The best AI agents for WhatsApp

The table orders the eleven options by their points out of 100, using the six criteria in the next section. The last column says how far a trial account got on October 28, 2026.

Each criterion scores 0 to 5 and is multiplied by its weight. What we saw in a trial scores 5; what the vendor documents but we could not see scores 3, not zero; what it does not publish scores 0. A tie goes to the lower cost, never to the publisher of the list.

Each cell is that criterion's 0 to 5 score; the points add up each score times its weight, divided by 5.

This is the cheapest plan with WhatsApp and the AI agent, for one number and three people, before tax. Equivalents use the European Central Bank rates of October 22, 2026; the messages Meta charges for are extra on every option.

“Documented” means the vendor publishes it in its help center or pricing page; “advertised” means it says so on a sales page; “we saw it” means it showed up in our trial. We saw no action run on a real customer.

Choose respond.io if your team works several channels, wants an agent that answers from your information, moves the contact to the next stage and hands off to a person, and can pay in dollars without a CFDI invoice. Growth, the first plan with AI agents, costs $159 USD a month billed yearly.

What we saw on October 28: we opened the 7-day Growth trial with no card and no phone number, and built an agent from the FAQ of a test furniture store. In the preview it quoted the sofa set's exact price; asked about shipping to Silao, it said it had no confirmed information and handed the conversation to a person with an internal summary; asked how to reserve a dining set, it gave the price and the deposit, told the customer not to pay in the chat and handed off as well. The channel screen offers the official WhatsApp Business API, and the account ships with lifecycle stages (New Lead, Hot Lead, Payment, Customer and Cold Lead) and usage meters.

What we could not check: the agent changing a contact or booking, since we connected no WhatsApp number and messaged nobody; that is why that criterion scores 3. respond.io documents that its agent closes conversations, assigns, updates contact fields and stages, adds comments, triggers workflows and books appointments. The account showed English and dollars, and we reached no option to pay in pesos or to get a CFDI invoice.

Choose Dapta if you want text and voice agents with no-code flows that qualify prospects and pass them to HubSpot or Salesforce, and you pay in dollars without a CFDI invoice. Pro costs $99 USD a month with five users.

What we saw on October 28: nothing inside the product. We did not attempt its trial; its documentation says the 7-day Pro trial asks for a card and turns into a paid plan unless you cancel, and we used no card in these trials.

What we could not check: anything inside the product. We scored it on what Dapta publishes: connection through the official API with Meta's embedded signup, booking and quote requests as agent use cases, and an inbox that assigns a person. It documents no sales stages of its own: prospects go to an external CRM. Its documentation asks for a number not registered on WhatsApp, it bills in dollars and it publishes no CFDI invoicing.

Choose Chatbase if your agent should act on tools you already use, such as Calendly, Stripe or Shopify, and learn from your documents and website. Hobby costs $40 USD a month with five actions per agent and two members; we could not confirm the price of a third, so its cost score drops one step.

What we saw on October 28: we opened a free account and saved a test text as a source. To create the agent, signup only offered 7-day trials of paid plans, with no free choice, and the free dashboard stayed without agents. That plan screen listed Hobby with 700 message credits a month.

What we could not check: the agent, its actions and WhatsApp, since signup would not let us create an agent without a paid plan. Chatbase documents actions to book, collect payment, capture prospects and escalate to a person, and lists WhatsApp among its channels without saying whether it uses the official API. It bills in dollars and publishes no CFDI invoicing.

Choose Aurora Inbox if you want to pay in pesos with a CFDI invoice and have an agent that books, sends follow-ups and alerts your team, for three people: $1,800 MXN a month plus VAT.

What we saw on October 28: nothing inside the product. We did not attempt the trial because its 7-day trial signup is paid, and we paid for nothing in these trials.

What we could not check: everything else. We scored it on what Aurora publishes: agent tools for follow-ups, routing to the team, booking, alerting a person and sending approved templates. Among them it documents no quoting and no change to the contact or the deal, which is why acting scores 1. It publishes no price for AI replies beyond the allowance.

Choose Eva if you want the agent to make the sale on WhatsApp: quote from your catalog, book, collect by SPEI bank transfer, create and update deals in the built-in CRM and follow up, with a CFDI invoice and the setup done by us. Eva is our product: Esencial costs $3,333 MXN a month billed yearly ($3,999 MXN month to month), plus Mexican VAT, with 5 users.

What we saw on October 28, from 8:41 to 9:13 p.m. Mexico City time: we tested it with the same case on a local copy of the current product, not in production. We created an agent without changing its default behavior and loaded the furniture store's FAQ. It quoted the sofa set's exact price; asked about shipping to Silao, it said the information only confirms free shipping in León, promising nothing; asked how to reserve the dining set, it worked out the deposit the store asks for and said it had no verified way to pay. In two of the three answers it asked for a name and mobile number to send the quote. It did not hand the conversation to a person: by default it has no handoff tool configured, and the conversation stayed unassigned, with a "Take conversation" button for the team. Each conversation created a contact with an open deal on the sales board linked to the agent. Eva has no self-serve signup and no free trial: signup is by invitation. Setup is included: we configure everything Eva does today, at no extra cost.

What we could not check: a real WhatsApp number, or the agent booking, collecting or changing a record, since we connected no calendar, payments or catalog in the test; that is why acting scores 3, what we document, like respond.io. The handoff to a person exists as a tool switched on per agent, but with the default settings it did not happen, which is why it scores 1. If you only need someone to answer questions, the chatbot list has cheaper options.

Choose Clientify if you want a CRM with sales processes, email and marketing in Spanish, with AI flows that answer from your knowledge and assign a person. Todo en uno costs $39 USD a month billed yearly and includes one user; we could not confirm the price of extra users, so its cost score drops one step.

What we saw on October 28: we opened the 7-day trial with no card and confirmed the email. Signup offers Mexican pesos as the account currency and warns it cannot be changed later; we could not get the choice to save or get past that screen. Its signup menu lists WhatsApp Web as a channel.

What we could not check: WhatsApp, the AI flows and the handoff. Clientify documents flows that answer from your knowledge base, collect information and assign a person; quotes and booking links belong to the CRM, not to documented agent actions, which is why acting scores 1. Its electronic invoicing is for Spain only; it publishes no CFDI invoicing.

Choose Kommo if your team already sells from a visual sales board and you want an agent that answers from your sources, updates the lead and moves it to the next stage. Avanzado costs $30 USD per user a month, with six months prepaid at least.

What we saw on October 28: the signup page advertises a 14-day full-access trial with no card. The form rejected the plus-sign alias email we used for every trial (“Enter a valid email”), so we did not get an account.

What we could not check: WhatsApp, the agent and the handoff. Kommo documents that its agent only runs configured steps: asking for information, updating the lead, starting a bot or transferring the chat; it does not edit custom fields or start conversations, and it stops replying when the AI credits run out. Booking with the agent starts on Pro, which is why acting scores 1 on Avanzado. It publishes no peso price and no CFDI invoicing.

Choose Leadsales if a small Mexican team wants an agent that qualifies WhatsApp prospects and moves them through the stages, with a peso price and a Mexican invoice. The agent is billed separately: Profesional costs $3,239.88 MXN a month and Lead Agent starts at $87 USD a month.

What we saw on October 28: the site offers a 14-day CRM trial. Signup accepted the email and password and reached “Personaliza tu cuenta”, which requires a personal WhatsApp number to send a code to; we stopped there.

What we could not check: the agent, the stages and the handoff, or whether the trial charges anything, since its page shows no trial price. Lead Agent documents replying, qualifying, moving the lead through the sales stages and passing it to your team; it documents no booking and no quoting, which is why acting scores 1. It can only be added to Profesional or Avanzado, on the official API.

Choose Wati if what you mostly need is the WhatsApp API with a team inbox, campaigns and an AI agent included on the entry plan: Growth costs EUR 59 a month billed yearly, ≈ MXN 1,240, with three users.

What we saw on October 28: the site advertises a 7-day trial with no card. The signup form requires a personal phone number, explicitly not the business one, and asks you to accept marketing messages; we stopped before submitting it.

What we could not check: anything inside the product. Wati publishes AI agents that handle conversations end to end and two commerce or CRM integrations on Growth, but it does not name which actions the agent takes or how it hands off; its inbox documents manual assignment. That is why acting and handoff score 1. Its page shows euros; a Mexico peso price is not verified, and it publishes no CFDI invoicing.

Choose Vambe if you would rather have the vendor build the agents and flows with you over a one-month implementation and you have a dollar budget: Standard costs $431 USD a month billed yearly, plus a $600 USD implementation.

What we saw on October 28: nothing inside the product. We did not attempt a trial; its pricing page has no free trial and no online checkout, buying goes through a consultation and the first month is a paid implementation.

What we could not check: anything inside the product. Vambe advertises agents that update your CRM, book meetings and process payments, with its own sales board; the handoff to a person appears in its customer stories, not in a guide, which is why it scores 1. Its terms say the customer must review and approve what the AI answers. It bills in dollars and publishes no CFDI invoicing.

Choose Mercately if you sell with a catalog, orders, PDF quotes and payment links in the same system as the agent: Scale IA costs $239 USD a month billed yearly, with five users.

What we saw on October 28: nothing inside the product. We did not attempt a trial; its pricing page offers to book a demo and publishes no free trial.

What we could not check: anything inside the product. Its agent, MIA, answers from your catalog, FAQs and guides, and escalates to a person; booking is listed as a use to train it for, without the connection's detail, and quotes and orders belong to the system, not to documented agent actions. That is why acting scores 1. It bills in dollars and publishes no CFDI invoicing.

If you want to try an agent today that answers, moves the contact to the next stage and hands off to a person, across channels and in dollars: respond.io.

If you need the agent to quote from your catalog, book, collect payment and log it all in the CRM, with CFDI invoices and the setup done by us: Eva.

If you want voice agents as well as text and to send prospects to HubSpot or Salesforce: Dapta. If your agent should use Calendly, Stripe or Shopify: Chatbase.

If paying in pesos with a CFDI invoice outweighs everything else: Aurora Inbox or Eva. If your team already sells from a visual sales board: Kommo or Leadsales.

If you only need someone to answer questions rather than act, a chatbot is enough and costs less: compare on the list of AI chatbots for WhatsApp.

On October 28, 2026, between 2:43 and 4:34 p.m. New York time, we tried to open a trial account at six of these tools with the same case: a furniture store in León, Mexico, with three customer questions (the price of a sofa set, shipping to Silao and how to reserve a dining set). We used no card, no WhatsApp number and no real contacts, and we messaged nobody.

Only respond.io let us build an agent: we saw it give the price, admit it knew nothing about shipping and hand the conversation to a person with a summary. We did not see it quote against a catalog, book or change a contact, since there were no contacts and no WhatsApp connected. We did not attempt Dapta, Mercately or Vambe, nor Aurora Inbox, whose trial is paid. We tested Eva, our product, with the same case that evening on a local copy of the current product: it answered all three questions without inventing anything, but with the default settings it did not hand the conversation to a person.

What we could not test anywhere: connecting a real WhatsApp number, the agent booking or changing a record with a real customer, and receiving a CFDI invoice. We review this list every month; the next review is on November 28, 2026.

Each price links to the vendor page it came from, with the date of the fact sheet that recorded it.
