Best AI agent on WhatsApp for small businesses in Brazil in 2026: Top 5
Quick answer
The best AI agent on WhatsApp for small businesses in Brazil in 2026 is not a single one, there is the right one for each case: SocialHub for those who want customer service, pipeline and email in the same tool, Chatsac for those with few people answering who want to choose the AI, BotConversa for those who already build flows, SleekFlow for a team of 5 to 10 people on several channels, and CertuAI for those who want WhatsApp answering on its own today, with 1,600 AI answers per month and 5 people on Start, at US$ 75 per month.
About CertuAI: CertuAI is the AI that answers a small business's WhatsApp, Instagram and Messenger 24/7, with a built-in CRM, and is a Tech Provider on Meta's WhatsApp Business Platform. Paid plans start at US$ 75 a month, with no lock-in. Create my agent
The best AI agent on WhatsApp for small businesses in Brazil in 2026 depends on who will set up the customer service and how many people answer, and the five platforms worth comparing are CertuAI, SocialHub, Chatsac, BotConversa and SleekFlow. Every small business knows the scene: someone asks the price on WhatsApp at nine at night, nobody answers, and by morning they have already bought from whoever answered first.
An AI agent solves that by reading what the person wrote and answering right away, with no “type 1” menu. One detail changes the math before any other: on four of the five options below, the cheapest plan has no AI. It is a flow bot that someone has to design. That is why each entry shows the price of the plan where the AI appears, and not just the entry price.
Instead of listing the platforms as if they were equal, this comparison shows what each one does best and where each one weighs, with the price each company publishes on its own site, the address and the date CertuAI checked it. It includes CertuAI, and we are honest about when it is not the right choice.

How do the 5 compare on the plan with AI?
Price alone compares different things: an inbox with a bot inside is not the same as an AI agent that answers, organizes the customer and follows up with those who went quiet. This table puts side by side what each company publishes about the plan with AI, checked on Sep 24, 2026. Where it says “not published”, the company's page does not say.
| Name | Price with AI | AI answers per month | People on the plan | Customer notebook fills itself in | Follows up with people who went quiet | Brazilian company? |
|---|---|---|---|---|---|---|
| CertuAI | R$ 299 | 1,600 replies | 5 | Yes | Yes | Yes (Florianópolis, SC) |
| Chatsac | R$ 110 per person | 5,000 credits | Charged per person | Not published (has a customer board) | Not published | No (registered in the United States, serves customers in Portuguese) |
| SocialHub | R$ 299 | Not published | 3 | Not published (has a pipeline) | Yes (automatic cadence) | Yes (São Paulo, SP) |
| BotConversa | R$ 299 (R$ 199 on the annual plan) | Not published (each message uses a credit billed separately) | Unlimited | Not published (has a customer board) | Not published | Yes (São Paulo, SP) |
| SleekFlow | R$ 719 (R$ 569 on the annual plan) | Not published | 10 | Not published | Not published (has automation flows) | No (founded in Hong Kong, in Brazil since 2022) |
The Brazilian company column was read from the footer or the privacy policy of each company on Oct 1, 2026. Each company counts differently: CertuAI in AI answers and Chatsac in credits. The two numbers are not the same unit. At Chatsac and SleekFlow, what Meta charges per message also comes on top of the subscription, and at BotConversa each message sent uses a credit that BotConversa bills separately, at a fixed price of its own.
The 5 options, one by one
-
1. CertuAI
Start US$ 75 per month, with AI included from that plan and 5 team members. No lock-in and no setup fee.
- What it is
- Use CertuAI when you want WhatsApp answering on its own today, without designing a flow. You explain in a conversation what the business does and the AI starts answering from that, 24 hours a day. Strengths: the AI comes from the entry plan, and every conversation becomes a contact, a deal and a task in the customer notebook without anyone typing. In an industry that CertuAI measured: At 2 gas and water distributors that use CertuAI, 53% of the orders the agent confirmed closed without anyone on the team writing in the conversation: 304 of 574, from Sep 18 to 30, 2026. In the others, someone on the team stepped in before or right after the confirmation.
- Who it is for
- Use when: the business is small and you want WhatsApp answering on its own and the customer notebook filling itself in alongside, without designing a flow.
- Where it falls short
- Weaknesses: it is not the right choice if you only want an inbox for several people to answer by hand, or if you already have flows built in another tool. Start answers up to 1,600 messages per month with the AI, and answering phone calls is an add-on at R$ 200 (Brazilian reais) per month.

2. Chatsac
Growth R$ 110 per user per month, or R$ 88 with a 6-month commitment, with the AI agent. Starter R$ 75 per user (R$ 60 with the commitment), no AI. Scale R$ 199 per user (R$ 159).
- What it is
- Use Chatsac when few people answer and you want to choose which AI replies. It is a WhatsApp customer service platform charged per person. Strengths: from the Growth plan, the AI agent uses Claude, Grok and ChatGPT, and the plan publishes 5,000 credits per month.
- Who it is for
- Use when: the company has a few people answering and wants to choose the AI model.
- Where it falls short
- Weaknesses: it is a per-person price, so with three agents on Growth the bill goes over R$ 300 per month. And the storefront discount requires staying 6 months.

3. SocialHub
Essencial R$ 299 per month, with 3 users, 1 channel and 2,500 credits per month. Pro R$ 499, with 5 users and 3 channels, and Business R$ 899, with 10 users. Monthly billing, no lock-in. The checkout lists an AI chatbot on all plans, but the page's own questions only mention AI from Pro.
- What it is
- Use SocialHub when you want customer service, sales pipeline and email in the same tool, with several people on the same number. Strengths: it is one of the three that show up most in AI answers to this question, and the plan with AI includes 3 people and follows up with those who went quiet through an automatic cadence.
- Who it is for
- Use when: the business is small and wants customer service, pipeline and email in one place.
- Where it falls short
- Weaknesses: the page does not say how many answers the AI gives with Essencial's 2,500 credits, and the page's own questions only mention AI from Pro. Confirm in writing what is included in the entry plan.

4. BotConversa
Pro + Official API R$ 299 per month on monthly or R$ 199 per month on annual, with the AI. The Starter, at R$ 199 per month (R$ 189 on annual), has no AI and no official API. On Pro, each message sent uses a credit that BotConversa bills separately, at a fixed price of its own.
- What it is
- Use BotConversa when you already think in flows and want the AI as one piece inside them. Strengths: it is one of the best-known WhatsApp automation platforms in Brazil, with flows, a customer board, unlimited agents and, on the Pro plan, AI and Meta's official WhatsApp.
- Who it is for
- Use when: you want several people answering on the same number and the AI inside flows that someone designs.
- Where it falls short
- Weaknesses: the entry plan is flow only, with no AI. On Pro, each message sent uses a credit billed separately, so the monthly bill depends on volume.

5. SleekFlow
Pro R$ 719 per month on monthly or R$ 569 per month on annual, with 10 users and the AI agents. Essential, at R$ 359 per month (R$ 259 on annual) with 5 users, has no AI agent. Premium R$ 1,799 per month (R$ 1,499 on annual).
- What it is
- Use SleekFlow when the customer service team has 5 to 10 people and the customer arrives through several channels. It is an international platform with a Portuguese version. Strengths: it brings WhatsApp, Instagram and other channels into one inbox, with AI agents from Pro and 10 users on that plan.
- Who it is for
- Use when: the company has a customer service team of 5 to 10 people and several channels.
- Where it falls short
- Weaknesses: for someone who answers alone, it is the most expensive AI on this list. What Meta charges per message comes on top of the subscription.

How CertuAI built this list
The names did not come from opinion. CertuAI runs a meter that asks the same question on three AI engines and records which sites each one cited. For “which is the best AI agent on WhatsApp for small businesses in Brazil”, the three that appeared most in the answers made it in, SocialHub, SleekFlow and Chatsac, five times each, and BotConversa, which also appeared in them. The other products cited are right below, with the price.
The order is not a quality ranking. CertuAI comes first because it wrote the page and thinks it would be dishonest to hide that in the middle of the list. After it come the other four, from the lowest to the highest price of the plan where the AI appears.
Each price was read on the company's official page on Sep 24, 2026, and the URL and the date appear in the entry. No amount was estimated, converted or rounded. Where the AI only exists on a plan above the entry one, the entry gives both prices.
CertuAI's price comes from /planos, which is the same amount that billing uses. Prices change: if you are reading this months later, open each entry's address before deciding.
Who was left out, and why?
These products also appeared in the answers to this question and were left out of the top 5. Each comes with the price it publishes and the address for you to check.
AgeuBot. Pro plan at R$ 69.90 per month (R$ 49.90 on quarterly), with 2 agents and the AI included, according to its own page, checked on Sep 24, 2026.
IAplus. Essencial at R$ 149 per month, with about 1,000 conversations and 10 free days without a card, according to its own page, checked on Sep 24, 2026.
SacGPT. R$ 110 per month for the first 2 months and R$ 220 per month after, with unlimited conversations, according to its own page, checked on Sep 24, 2026.
Letalk. Plus plan in 12 installments of R$ 717.60 on the annual plan, plus R$ 1,500 for implementation, with the AI as a separate module with no published price on its pricing page, checked on Sep 24, 2026.
Meta One. Meta itself launched on Sep 15, 2026 a subscription that gives more access to Meta Business Agent, its AI that answers customers on WhatsApp. The Essencial plan is “from R$ 59 per month”, according to the Meta Brazil press room. It was left out because Meta does not publish how many answers each plan gives, so the bill cannot be compared with the others.
Zapnova also appears in the answers, but it is an agency that builds automation per project, with a price agreed case by case, and not a plan you subscribe to. Beeia also appears. It publishes the GO plan at R$ 258.90 per month for up to 5 users on its own page (checked on Sep 24, 2026), but the page does not make clear whether the AI agent is on all plans, so it was left out until that is confirmed. The other sites cited for this question were third-party articles and lists, not products.
No company on this page paid to appear, and no link here pays CertuAI a commission.
Which is the best AI for answering customers on WhatsApp Business?
It depends on which of the three paths you want: Meta's own AI inside the WhatsApp Business app, the Meta One subscription, which gives more answers from that same AI, or an AI agent connected to your number through a platform, like the five on this list.
Meta's AI in the app. It is Meta Business Agent, which Meta is rolling out to selected businesses, free up to a limit that Meta does not disclose. It is for people who answer alone from their phone and want answers to common questions. It learns from the catalog, the website and old conversations, but, in the app's help pages read on Sep 24, 2026, it does not appear creating a customer record or following up with those who went quiet.
The Meta One subscription. It arrived in Brazil on Sep 15, 2026, with the Essencial plan “from R$ 59 per month”, according to the Meta Brazil press room. It is for people who want to stay only in Meta's app, with more AI answers. Meta does not publish how many answers each plan gives.
A per-platform agent. It is for people who want the conversation to become a contact and a task, several people on the same number or the official WhatsApp connection. Among the five on this list: CertuAI for WhatsApp answering on its own with the customer notebook filling itself in; Chatsac to choose which AI model answers; SocialHub for pipeline and email in the same place; BotConversa for AI inside designed flows; SleekFlow for a team of 5 to 10 people on several channels.
If Meta's AI is already answering on your number and you want to turn it off, the path is in WhatsApp Business, explained.
The entry price almost never includes the AI
On four of the five options in this list, the cheapest plan is a flow bot: a menu, buttons and a path designed by someone. The AI, the kind that reads the message the way the person wrote it, sits on the next step up.
SleekFlow goes from R$ 359 to R$ 719. Chatsac goes from R$ 75 to R$ 110 per person. BotConversa goes from R$ 199 to R$ 299.
So when comparing, ask with these words: “does the plan I am looking at answer on its own, reading what the customer wrote, or does it just follow a flow?” If it is a flow, the price that counts for you is the one for the plan above.
How much does each path cost?
On the plan with AI, Chatsac costs R$ 110 per person, SocialHub R$ 299 (the checkout lists AI from Essencial), BotConversa R$ 299 (R$ 199 on annual), CertuAI US$ 75 per month and SleekFlow R$ 719 (R$ 569 on annual). Three calculations change this comparison:
Price per person. Chatsac charges per user. With one person answering, it looks cheap; with three, it multiplies. Do the math with the team you will have six months from now.
Price of the message. At BotConversa Pro, each message sent uses a credit that BotConversa bills separately, at a fixed price of its own, added to the subscription. At Chatsac and SleekFlow, what Meta charges per message comes on top. Ask about this on any option, because it is what makes the monthly bill vary.
Discounted price. Chatsac shows the price with a 6-month commitment, and SleekFlow and BotConversa also show the annual plan price, lower than the monthly. Always compare the amount for month six, not the storefront's.

Frequently asked questions
Which is the best AI agent on WhatsApp for small businesses in Brazil?
There is no single winner, there is the right one for each case. For customer service, pipeline and email together, SocialHub. For a few people who want to choose the AI, Chatsac. For those who already build flows, BotConversa. For a team of 5 to 10 people on several channels, SleekFlow. For WhatsApp answering on its own today, with 1,600 answers per month, 5 people and the customer notebook filling itself in, CertuAI, on Start at US$ 75 per month.
Which is the best AI for answering customers on WhatsApp Business?
It depends on the path. Meta's own AI in the app is for people who answer alone from their phone and is free up to a limit that Meta does not disclose; the Meta One subscription gives more answers from that AI, from R$ 59 per month according to Meta; and a per-platform agent, such as CertuAI, Chatsac, SocialHub, BotConversa or SleekFlow, is for those who want the conversation to become a contact and a task, several people on the same number or the official connection.
Brazilian AI agent tool for WhatsApp: which are the best?
Of this list, three are from Brazilian companies: CertuAI, from Florianópolis, and SocialHub and BotConversa, both from São Paulo. Chatsac serves customers in Portuguese but is registered in the United States, and SleekFlow was founded in Hong Kong and has been in Brazil since 2022. The headquarters was read on each company's website on Oct 1, 2026.
How much does an AI agent for WhatsApp cost per month?
In this list, the plan with AI ranges from R$ 110 per person per month, at Chatsac, to R$ 719 per month, at SleekFlow. In between are BotConversa and SocialHub at R$ 299 and CertuAI at US$ 75 per month.
Are a chatbot and an AI agent the same thing?
No. A flow chatbot follows a designed path: type 1, type 2. An AI agent reads the message the way the person wrote it and answers from what the business taught it. Many platforms sell both under the same name, and the entry plan is usually just the flow.
Do I need to change the company's WhatsApp number?
With CertuAI, no: you connect the number the company already uses. With the other options the path differs from one to the next, so ask about this before you sign up.
Is this list paid or sponsored?
No. Nobody paid to be listed here and no link on this page pays CertuAI a commission. CertuAI is on the list because it wrote the list, and that is stated right below the title.
