10 Best WhatsApp AI Agent Platforms Compared (2026)

Summarise this post with:

A WhatsApp AI agent is software that answers customer questions, qualifies leads and takes real actions like checking an order or booking a slot, on its own, over the official WhatsApp Business API.

Unlike a keyword chatbot, it understands what a customer means rather than matching fixed phrases.

This guide compares the 10 best WhatsApp AI agent platforms in 2026 on pricing, included message quotas, knowledge base support and tool calling.

Every figure was checked against each vendor's own pricing page.

AiSensy's WhatsApp AI Agent costs ₹3,500/month and includes 3,500 AI messages, a knowledge base, long-term user memory and tool calling, with 500 free AI messages to test before you pay.

It trains on your website the same day you set it up, with no developer needed.

WhatsApp AI agent vs basic keyword chatbot: what changes for your business

A keyword chatbot breaks the moment a customer types something it doesn't expect, and then a real person has to step in anyway, so you've paid for automation and still need the headcount.

A WhatsApp AI agent handles the conversation the way a trained employee would: it understands what the customer actually wants, remembers what was said earlier, and can look up an order or book a slot without anyone watching the chat.

The difference isn't technical. It's whether you still need a human standing by.

A keyword bot on WhatsApp is fine for one narrow, predictable job, share a price list, confirm a demo slot.

Anything with real volume or variety, support queries, lead qualification, order tracking, needs an agent that doesn't fall over the moment someone phrases things differently.

Every platform in this guide is a genuine AI agent, not a keyword bot with an AI label, and the entries below flag where that line gets blurry.

10 best WhatsApp AI agents compared

The right AI agent isn't the one with the longest feature list, it's the one that actually stops a support ticket from reaching a human, or gets a lead qualified before your sales team wakes up.

The 10 platforms below cover everything from a same-day no-code setup to fully custom builds for teams with engineers to spare.

1. AiSensy — get a full funnel WhatsApp AI agent today

Best for: Indian SMBs and D2C brands running WhatsApp as their main sales channel

Verified BSP: Yes (AiSensy Communications Pvt Ltd, official Meta Business Partner)

WhatsApp AI agent pricing: ₹3,500/month

Included quota:  3,500 AI messages/month, plus 500 free AI messages for testing

Knowledge base: Yes, just point it at your website, or upload PDFs, docs and spreadsheets, up to 50MB each

Tool calling: Yes, it can update a customer's record and hand off to a human on its own, no engineering required

What it actually saves you: The setup time. Paste your website URL and the agent is trained on your business the same day, so you're not waiting weeks for an implementation project.

Most businesses don't have a spare engineer to wire up an AI agent on WhatsApp, and AiSensy is built for that reality.

You pick a tone (Friendly, Professional, Concise or Playful), tell it what it's allowed to do, and it starts answering customers on the official WhatsApp Business API, understanding mixed-language messages including Hinglish, not just textbook English.

When it genuinely can't help, it hands off to your team instead of guessing.

Pros:

• Live the same day. No developer, no weeks-long onboarding.
• Updates customer records and escalates to a human on its own, so nothing falls through the cracks.
• Understands customers who type in Hinglish or mixed language, which most platforms in this list don't advertise handling at all.

Cons:

• 3,500 AI messages a month covers most SMBs, but a high-volume brand should confirm what happens past that before committing.
• Meta's standard WhatsApp conversation fees apply on top, as they do with every platform in this guide.
• You shape the agent's tone with presets and one instruction field, not raw prompt access, which is a feature for most teams and a limit for one that wants to hand-write every response rule itself.

Verdict: If you want an AI agent answering real customers this week, without hiring a developer to build it, this is the fastest path there.

2. Respond.io: for teams already juggling WhatsApp, Instagram and email in one inbox

Best for: Support teams drowning in messages across multiple channels who want one AI agent covering all of them

WhatsApp AI agent pricing: Included from the Growth plan, $159/month billed annually ($199/month monthly)

Included quota: Not sold as a separate AI quota; tracked by Monthly Active Contacts instead

Knowledge base: Not published. Confirm with the vendor before committing volume.

Tool calling: Yes, Developer API and webhooks from Growth up, so it can talk to your other systems

What it actually saves you: The tool-switching. Your team stops jumping between apps to handle WhatsApp, Messenger and Instagram separately.

If your support team already lives in Respond.io because they're fielding messages from ten different channels, adding the AI agent means those channels get automated coverage without adopting a second platform just for WhatsApp.

Pros:

• One inbox for every channel, so agents aren't switching tools mid-shift.
• The Developer API is included at this tier, so custom actions aren't a paywall away.
• Backed by a large, strong independent review base.

Cons:

• You can't get the AI agent without also paying for the multichannel platform around it, so it's a poor fit if WhatsApp is your only channel.
• No published AI-specific quota means your bill moves with contact volume, which is harder to forecast.
• Overkill if you just need WhatsApp handled, not five channels.

Verdict: Worth it if your team's real problem is too many channels, not just WhatsApp.

3. Wati (Astra): a dedicated AI product if you're ready to pay for unlimited agents

Best for: Teams that want AI agent capability sold and priced on its own, with a free tier to try first

WhatsApp AI agent pricing: Astra Pro $79/month annual ($99/month monthly); Astra Business $319/month annual ($399/month monthly)

Included quota: Pro: 3 agents, 5,000 credits, 50MB training data. Business: unlimited agents, 25,000 credits, 100MB

Knowledge base: Yes, scaling with the tier

Tool calling: Yes, HubSpot, Salesforce and Slack connections; deeper API access on Business

What it actually saves you: A trial period. You can test the agent free before spending anything.

Astra is Wati's answer to "just let us try it first," a genuine free tier with 1 agent and 100 credits, before you ever pay.

The catch shows up when you outgrow, Pro: Business jumps to $319 a month, a step most SMBs feel.

Pros: 

• Free tier means you can test drive it before a single rupee changes hands.
• Voice agent support from Pro, not locked behind Enterprise.
• Transparent credit-based pricing, no guessing at overage.

Cons:

• The jump from Pro to Business is steep, roughly 4x, once you need more than 3 agents.
• 50MB of training data on Pro is tight if your product catalogue or docs are heavy.
• Standard Meta conversation fees still apply on top of the Astra subscription.

Verdict: Try the free tier first. If you outgrow it fast, budget for the jump to Business early rather than getting surprised by it.

4. Interakt: three specialised WhatsApp AI agents for one flat add-on

Best for: Existing Interakt users who want sales, support and lead qualification automated without adding a new tool

WhatsApp AI agent pricing: ₹3,000/month add-on, requires the Growth or Advanced base plan

Included quota: 100 free AI messages, then ₹0.50 per additional message

Knowledge base: Not confirmed from primary source, verify before publishing

Tool calling: Not confirmed from primary source, verify before publishing

What it actually saves you: Buying three separate tools. Sales, support and lead qualification run as one add-on instead of three subscriptions.

If you're already on Interakt's Growth or Advanced plan, the AI add-on is the cheapest way in this list to get three distinct agent types working at once, for a flat ₹3,000.

Pros:

• Three agent types, sales, support, lead qualification, in one add-on price.
• Predictable overage at ₹0.50 a message, no surprise billing.
• No large upfront cost to test it once your base plan is in place.

Cons:

• You need Growth or Advanced first, so the real starting cost is higher than ₹3,000.
• 100 free messages a month disappears fast on an active line.
• Knowledge base and tool-calling depth aren't public; confirm directly before betting real volume on it.

Verdict: Makes sense if you're already paying for Interakt's higher tiers. Not worth switching to just for this.

5. Botpress: build the exact agent you want, if you have engineers to spare

Best for: Product and engineering teams who want to design the agent's logic themselves, not configure a preset

AI pricing: Plus tier $150/month annual, the first tier with WhatsApp access

Included quota: 250 conversations/month, unlimited AI agents included on Plus

Knowledge base: Yes, structured knowledge sources through Botpress Studio and Desk

Tool calling: Yes, full API access and custom logic building

What it actually saves you: Nothing, upfront. This is the platform you pick when the other nine are too restrictive for what you're building, and you're trading setup time for control.

Botpress doesn't sell you a finished agent, it sells you the building blocks. That's exactly right for a team that wants to design custom logic, and exactly wrong for a founder who wants something live by Friday.

Pros:

• Unlimited WhatsApp AI agents from the first paid tier, unusual generosity in this market.
• Full control over the agent's behaviour for teams that need it.
• Transparent, published tiered pricing.

Cons:

• No way to test WhatsApp specifically without paying first, the free tier excludes it.
• 250 conversations a month on Plus is thin for a live support line.
• If you don't have engineering time to spend, you'll be slower to launch here than on any no-code platform in this list.

Verdict: Pick this only if configuring a preset agent genuinely isn't enough for what you're building.

6. Gallabox, AI qualification bundled into your regular plan

Best for: Sales teams running WhatsApp and Instagram together who want AI qualification without an extra line item

WhatsApp AI agent pricing: Included in tier pricing; Basic ₹2,399/month, Essential ₹5,599/month, Advanced ₹13,599/month, all billed annually

Included quota: 500 AI credits (Basic), 2,000 (Essential), 8,000 (Advanced)

Knowledge base: Yes, scaling from 10MB up to 1GB by tier

Tool calling: Yes, data extraction webhooks and API access from Advanced

What it actually saves you: A separate AI bill. Credits are baked into the subscription instead of sold as an add-on.

Gallabox skips the "base plan plus AI add-on" math entirely, AI credits are just part of what you're already paying for, and it's one of the few platforms here offering AI voice, not just text chat, before you hit the top Enterprise tier.

Pros:

• No separate AI purchase, it's already in the plan you're paying for.
• AI voice on WhatsApp and phone from the Advanced tier, ahead of most competitors.
• Free trial with 500 AI credits to test on real conversations.

Cons:

• No monthly billing option, annual is the only way in, so you're committing for a year minimum.
• Knowledge base support on the entry Basic tier is limited.
• Running past your AI credit allowance adds to the bill each month.

Verdict: A strong pick if AI qualification plus Instagram coverage both matter and you're comfortable committing annually.

7. Chatbase — train an agent on your docs and deploy it everywhere, not just WhatsApp

Best for: Teams that want the same AI agent answering customers on WhatsApp, their website and other channels from one brain

WhatsApp AI agent pricing: Standard tier $150/month (monthly confirmed; annual pricing not confirmed at time of writing)

Included quota: 4,000 message credits/month, 3 team members

Knowledge base: Yes, scaling from 1MB (Free) to 40MB (Pro), with auto-retrain on paid tiers

Tool calling: Yes, Zendesk, Salesforce, HubSpot and Shopify integrations from Standard up

What it actually saves you: Rebuilding the agent for every channel. Train it once, deploy the same brain to WhatsApp, your website widget and Slack.

Chatbase treats WhatsApp as one deployment target among several, so if you're already sold on training an agent from your documents and want it everywhere, not just on WhatsApp, this fits differently than the WhatsApp-first platforms above it.

Pros:

• Pick your underlying AI model, OpenAI, Anthropic, Gemini and others, on paid tiers.
• One trained agent works across WhatsApp and several other channels.
• Clear, published pricing and a detailed comparison table.

Cons:

• WhatsApp specifically needs the Standard tier or above, the cheaper Hobby tier doesn't include it.
• Extra agents cost $300/year each, on top of your base plan.
• Removing "Powered by Chatbase" branding is another $99/month.

Verdict: The right call if you want one agent everywhere, not just WhatsApp. If WhatsApp is your only channel, you're paying for reach you won't use.

8. ManyChat — if WhatsApp is one channel in a bigger creator or marketing play

Best for: Creators and marketers already running Instagram and TikTok automation who want WhatsApp folded in

WhatsApp AI agent pricing: Base plans from $14 to $17/month. AI add-on pricing is not published separately.

Included quota: Contact-based, scales with Active Contacts per plan

Knowledge base: Not published. Confirm with the vendor before signing up.

Tool calling: Not confirmed from primary source, verify before publishing

What it actually saves you: Running separate tools for Instagram, TikTok and WhatsApp. One automation layer covers all three.

ManyChat's real strength is social automation, DMs, comments, follow-up sequences, with WhatsApp as one more channel in that mix rather than the main event.

Pros:

• One platform for WhatsApp, Instagram, Messenger, TikTok and SMS.
• Free tier to test before paying anything.
• Official Meta and TikTok Business Partner status.

Cons:

• AI agent capability isn't the platform's main selling point, confirm the current features and pricing directly before betting on it as a WhatsApp AI tool specifically.
• Pricing moves with your Active Contacts, which can shift your bill mid-cycle.
• If WhatsApp depth is what you actually need, this isn't built for that first.

Verdict: Good if your marketing already lives across Instagram, TikTok and WhatsApp together. Not the pick if WhatsApp is the whole job.

9. Yellow.ai — built for enterprises with a budget and a sales call ahead of them

Best for: Large enterprises that need a fully custom, unlimited-scale deployment and have the budget for it

AI pricing: Not published. Free tier exists; everything past it requires an Enterprise contract, "Contact us" only

Included quota: Free tier: 500 sessions/month, then $0.99 per resolution after that

Knowledge base: Yes, depth not detailed publicly

Tool calling: Yes, unlimited on Enterprise

What it actually saves you: Nothing you can calculate without a sales call. This is the platform for a business big enough that a custom quote is the normal way to buy software.

If you're comparing prices on a spreadsheet before committing to anything, Yellow.ai won't give you a number to put in that spreadsheet, only a "Contact us" button.

Pros:

• Enterprise tier genuinely scales to unlimited agents, channels and integrations.
• Free tier lets you test before any commitment.
• Covers 35+ channels beyond WhatsApp for large omnichannel operations.

Cons:

• No public pricing between Free and Enterprise, you can't compare costs without talking to sales.
• The Free tier's $0.99-per-resolution overage adds up fast past 500 sessions.
• Not practical for an SMB trying to compare options quickly.

Verdict: Right for a large enterprise with a real budget conversation ahead. Everyone else will find a faster, clearer-priced option above.

10. Twilio, for engineering teams building their own agent, not buying one

Best for: Teams with developers who want to build a fully custom AI agent using their own choice of AI model

WhatsApp AI agent pricing: No packaged AI agent exists.

Pay-as-you-go: $0.005/message (Twilio's own fee) plus Meta's per-template fee by category and country

Included quota: None, fully usage-based

Knowledge base: Not applicable, Twilio is messaging infrastructure, not a built-in AI layer Tool calling: You build this yourself through Twilio's API

What it actually saves you: Nothing directly, but it gives you complete control if the other nine platforms are too restrictive for what you're building.

Be clear on what you're buying here: Twilio doesn't sell a WhatsApp AI agent. It sells the messaging pipes, at a transparent, published rate, that your developers connect to whichever AI model you choose. Everything else in this guide is a product. This is a construction kit.

Pros:

• Fully transparent, published pricing with a live calculator, no sales call needed to estimate cost.
• Complete freedom to choose your own AI model and build exactly the behaviour you want.
• Reliable infrastructure trusted at real scale.

Cons:

• There's no agent here to buy, only the parts to build one, real engineering time required.
• Your AI model costs (OpenAI, Anthropic, etc.) are entirely separate and not included in anything Twilio charges.
• Wrong choice if you want something live this week without a developer.

Verdict: Only worth it if you have engineers and specifically want to own every part of the agent's behaviour. Every other platform on this list ships faster.

Which WhatsApp AI agent should you pick for your business?

The real question isn't which platform has the most features, it's which one gets a working AI agent answering real customers this week, without you needing an engineer on standby.

If that's you, AiSensy is built for exactly that: live the same day, trained on your own website, handling WhatsApp as your main channel.

If WhatsApp is one channel among many you're already juggling, Respond.io or ManyChat fold it into what you're already running.

If you've got engineers who want to build something custom from scratch, Botpress or Twilio hand you the raw materials.

And if you're an enterprise with a real budget and a sales team ready to negotiate, Yellow.ai is built to go that far.

Is there a free WhatsApp AI agent?

Yes, several platforms let you test a WhatsApp AI agent before paying. Wati's Astra has a free tier with 1 agent and 100 credits.

Gallabox offers a free trial with 500 AI credits. Yellow.ai's free tier covers 500 sessions a month.

ManyChat has a free plan. AiSensy includes 500 free AI messages to test the agent before you pay.

The quotas differ enough that "free" means something different on each platform, so check the specific number before assuming they are comparable.

How we verified WhatsApp AI agent pricing for this guide

Every price here was checked against each platform's own pricing page in July 2026, not against aggregators, resellers, or AI-generated summaries.

While researching this guide, we found Google's own AI Overview stating the wrong price for three of these platforms, off by as much as 40% in one case, and describing a pricing structure for another that didn't match the vendor's actual page at all.

We're flagging this because it's a live example of how easily wrong numbers spread when nobody checks the source, and it's exactly why every figure below is pulled from the vendor's own pricing page, not a summary of one.

Where AI-specific pricing wasn't published separately from the base platform, we say so rather than guess.

AiSensy appears in this guide and is held to the same sourcing standard as every other platform.
