What Is AI Assistant Bot and How Do You Use Its Free AI Chat?

Updated

AI Assistant Bot (aiassistantbot.pages.dev) is a browser-based chat site that lets you talk to 30+ AI models in one place. The page describes it as free to use and lists models from Mistral, Meta, DeepSeek, Alibaba, Moonshot, Zhipu, Microsoft, and OpenAI's open-weight line. You open the site, pick a model, and start typing — no pricing page or payment step appears in the site's materials. Treat "free" as the site's own claim and expect possible rate limits or model availability changes over time.

What the site offers

The chat interface is the core product. The page shows a greeting ("Hello There!") and the prompt "Talk to your own assistant!" alongside a model list, an attach-file button, image generation, and chat save/import controls.

Model families available

Family Models listed on the page

Microsoft Phi 3 Small, Phi 3 Medium
GPT OSS GPT OSS-20B, GPT OSS-120B
MiniMax Minimax M2

That's 36 model entries, which matches the "30+ AI Models" description. The mix covers general chat, reasoning (DeepSeek R1 Zero, Kimi K2 Reason, Magistral), coding (Codestral, Devstral 2, the Qwen Coder models), and vision (the Pixtral models and GLM 4v Flash, based on their naming).

How to start a chat

  1. Open the site. Go to aiassistantbot.pages.dev in a browser. The landing view shows the greeting and the model selector.
  2. Choose a model. Pick from the list based on your task — a reasoning model for multi-step problems, a coder model for programming, a general model for everyday questions. If you're unsure, start with a mid-size general model like Mistral Small or Llama 3.3-70B.
  3. Type your message. Enter your prompt in the chat box and send it. The reply comes from the model you selected.
  4. Attach files if needed. The paperclip icon lets you upload a file to the conversation, so you can ask questions about a document or image.
  5. Save or move your chat. Use the download control to save the conversation, and the import option to bring a saved chat back in later.

Expected results and common snags

You should see a streamed or returned answer in the chat pane within a few seconds, depending on the model's size and current load. Things that commonly go wrong:

  • A model doesn't respond or is missing. Large models get swapped or throttled; switch to another entry in the same family.
  • Uploads are rejected. Check file type and size — the page doesn't state limits, so try a smaller file if an upload fails.
  • Answers feel slow. Bigger models (Mistral Large, Qwen 3 235B, Llama 4 Maverick) take longer than small ones. Use a smaller model for quick drafts.

Extra features beyond text chat

  • Image generation. The page includes a "Generate Images" option, so the site isn't text-only.
  • Chat import/export. You can download a conversation and import it later, which is useful for keeping a record or continuing a session on another device.
  • File attachment. Uploads let you work with documents or images inside the chat rather than pasting text.

Is it actually free?

The site's own description says "Chat with 30+ AI Models for free," and the page shows no pricing links, subscription tiers, or payment platforms. That said, the materials don't spell out usage caps, so don't assume unlimited access. If you hit a limit, the practical fallback is to switch models or return later.

Who it's for

AI Assistant Bot suits people who want to compare model behavior without signing up for several services — for example, testing whether a coder model handles a snippet better than a general one, or using a vision model to describe an uploaded image. It's less suited to work that needs guaranteed uptime or documented data-handling terms, since none of that appears in the site's materials.
