For a small or mid-size business that wants AI to answer, sell and take orders on WhatsApp, Yusr is the lowest-cost option with AI included on every plan and a free plan. respond.io suits larger teams on many channels, Wati suits WhatsApp marketing and broadcasts, SleekFlow suits teams that need calls and CRM connections, and ManyChat suits creators running Instagram comment-to-DM funnels.
Who wrote this list, and how were the tools picked?
We make Yusr, so read this as a list from one of the vendors. To keep it useful, every fact about the other tools comes from their own pricing pages and help centres as of October 2026, each one is linked under Sources, and we say plainly where another tool is the better choice.
We picked the five tools that business owners most often compare when they look for an AI agent on WhatsApp: tools that answer customers, not just send campaigns. Prices change and can differ by country, so check each pricing page before you buy.
How do the five compare side by side?

1. Yusr: an AI employee included in every plan
Yusr answers customers on WhatsApp, Instagram, Messenger, Telegram, LINE, Viber, SMS and email from your own prices, products and documents. It takes orders and reads them back before recording them, books appointments in Google Calendar on Basic and up, transcribes every voice note and can reply by voice, and hands hard chats to a person with a summary.
It replies in the language each customer writes in, and you choose the Arabic dialect (Gulf, Saudi, Egyptian, Levantine and others). Plans: free with 10 conversations a month, then Starter $49, Basic $150, Business $350 and Scale $600 a month.
- Best for: businesses that want the AI to sell and take orders, not only answer FAQs.
- Watch out: no TikTok, WeChat or voice calls, and WhatsApp campaigns go to up to 1,000 numbers at a time; if calls or very large broadcasts matter most, look at SleekFlow, Wati or respond.io.
2. respond.io: many channels for larger teams
respond.io puts WhatsApp, TikTok, Messenger, Instagram, WeChat, LINE, Viber, Telegram, website chat, SMS, email and calls in one inbox. Its AI Agents learn from files and public web pages and can act on audio messages.
- Best for: teams of five or more managing leads at volume, including calls.
- Watch out: AI Agents start on Growth at $159 a month billed yearly, and there is no free plan.
3. Wati: WhatsApp marketing with an AI add-on
Wati is strongest at WhatsApp broadcasts, chatbot flows and integrations; it lists more than 100 apps. Its AI agent, Astra, is trained on your knowledge base and catalogue and is billed separately from the inbox plans.
- Best for: businesses whose main WhatsApp job is campaigns and flows.
- Watch out: the inbox starts at $119 a month billed yearly, and AI costs extra.
4. SleekFlow: broadcasts, calls and CRM connections
SleekFlow covers a wide channel list including WeChat, TikTok and voice calls, and connects to Shopify, HubSpot and Salesforce. Its AI agents learn from crawled websites and internal documents.
- Best for: teams already running Shopify or a CRM that want calls in the same place.
- Watch out: no free plan, and its AI pages we checked do not detail Arabic dialects or voice-note handling.
5. ManyChat: Instagram and TikTok growth on a small budget
ManyChat is built around rule-based automations: comment and story triggers, lead capture and funnels. It is the cheapest paid option here, starting at $17 a month.
- Best for: creators and brands growing an audience on Instagram and TikTok.
- Watch out: its AI Replies work on Instagram only and are in beta, and per its help centre its AI cannot interpret audio.
How do you choose the right one?
Write down the three questions customers ask most, then test each tool with a free plan or trial on exactly those questions.
- If customers ask prices, stock and want to order in the chat, choose a tool whose AI answers from your catalogue and confirms orders.
- If many customers send voice notes or write in Arabic dialects, test those first; most tools do not list dialect choice.
- If your main job is sending campaigns, a marketing-first tool fits better than an AI employee.
- Count the full cost: plan, users, AI credits, and Meta's own WhatsApp fees.
What will WhatsApp itself cost on top of the tool?
On the official WhatsApp Business Platform, Meta bills separately from any of these tools. From 1 October 2026, Meta gives each business phone number 1,000 free delivered service messages a month and charges per message after that; template messages (order updates, follow-ups) are charged by Meta's rates for your country.
Questions people ask
What is the best AI agent for WhatsApp?
It depends on the job. For an AI that answers from your catalogue, takes confirmed orders and replies to voice notes, starting free, Yusr fits. For large multi-channel teams, respond.io; for WhatsApp marketing, Wati; for calls and CRM connections, SleekFlow; for Instagram growth funnels, ManyChat.
Which WhatsApp AI agent has a free plan?
Of these five, Yusr (10 conversations a month) and ManyChat (25 active contacts) have free plans. respond.io, Wati and SleekFlow offer free trials instead, as of October 2026.
Which WhatsApp AI agent works best in Arabic?
Yusr lets you choose the Arabic dialect, such as Gulf, Saudi, Egyptian or Levantine, and replies to Arabic voice notes. The other four describe their AI as multilingual but do not list a dialect choice on the pages we checked.
