The 5 options, one by one
-
1. CertuAI
It comes out of the account credit: each answer costs what that AI used, and the number appears next to the answer. There is an annual chat-only plan and one-off credit packs. The prices are under "How much does it cost to use the AIs on CertuAI?", further down.
- What it is
- A chat with 24 AIs from 10 companies, including Claude, GPT, Gemini, DeepSeek, Qwen and Llama. You write the question once and up to 3 AIs answer side by side. It reads PDFs and images, searches the web and saves your conversations. The AI agent that serves customers on WhatsApp and the CRM live in the same account.
- Who it is for
- Business owner who wants to compare answers and use the same account to serve customers. The AI can answer knowing what your company sells.
- Where it falls short
- It is not unlimited use: the credit runs out, and a heavier AI uses more than a light one. It does not generate images yet. If you just want to chat freely, with no business involved, you are better off with an unlimited-use subscription.

How CertuAI built this list
The list includes platforms that bring AIs from more than one company into a single chat and that show the price on their own page. Each price was read on the official page on Oct 12, 2026 and is written in the currency and format in which it was published. Nothing was converted.
CertuAI's numbers come from its own system on the same day: 24 AIs, 10 companies and up to 3 answers side by side. Poe and Monica were left out because the price could not be read on the page. Nobody paid to appear here.
How much does it cost to use the AIs on CertuAI?
You pay in credit, and each answer costs what that AI used. On Oct 12, 2026, an answer of about a thousand words costs from 7 credits (Mistral Small 3.2) to 1,680 credits (GPT-6-astra). The cost appears next to each answer, and the balance sits at the top of the screen.
The chat's annual plan costs R$ 588 (Brazilian reais) per year and gives 50,000 credits per month. It does not renew on its own: when the year ends, you decide whether to buy again.
If you would rather not commit to a year, you buy a one-off pack: 60,000 credits for R$ 69 (Brazilian reais), 150,000 credits for R$ 149, 350,000 credits for R$ 299. If you already have a CertuAI plan, the chat uses the plan's own credit. See the math for each type of use in how much the AI costs.
Unlimited subscription or credit per answer: which to choose?
An unlimited subscription suits people who chat a lot, every day. You pay the same amount using little or a lot. Inner AI works this way on the Pro plan, within a fair-use rule.
Credit per answer suits people who use it now and then or want to pick the AI for each question. A light AI costs little, a heavy one costs more, and you see the spend right away. CertuAI and OpenRouter work this way.
How do you compare three AIs with the same question?
1. Open the CertuAI AI chat and choose up to 3 AIs.
2. Write the question once. If you want, attach a PDF or turn on web search.
3. Read the answers side by side and keep the best one.

Do I need a CertuAI plan to use the AI chat?
No. You can buy just the chat's annual plan or a credit pack. If you already have a CertuAI plan, you use the plan's own credit.

It depends on the platform. CertuAI reads PDFs, images and text files and searches the web, but does not generate images yet. Inner AI, Adapta and ChatLLM advertise image generation.
