A Free AI Chatbot That Reads Files, Draws Charts & Generates Images

No sign-up, no paywall: chat with an open-source AI that analyzes PDFs and spreadsheets, searches the web with sources, and generates images — all in one conversation.

Most “free” AI chatbots come with a catch: an account, a phone number, a message cap you hit in five minutes, or the good features locked behind a subscription. The ToolBox AI chatbot takes the opposite approach — open the page, type, done. No sign-up, 30 free messages a day, and every capability enabled from the first message.

One conversation, many tools

  • File analysis: attach a PDF, Word, Excel or CSV file and ask anything — “summarize this contract”, “what are the key numbers here?”, “compare these columns”.
  • Real data work: for spreadsheets, the assistant writes and runs actual Python code, then hands you a downloadable chart right in the chat.
  • Image generation: “generate an image of a cabin in a foggy forest” — done in seconds.
  • Image understanding: send a photo and it describes it, answers questions about it, or extracts its text (OCR).
  • Live web search: for prices, news and anything recent, it searches the web itself and cites its sources.

What's under the hood?

The engine is the latest open-source Qwen model — natively multimodal (it understands text and images together) and competitive with well-known commercial models in independent benchmarks. It runs on our own GPU servers, which is exactly why there's no third-party data sharing: your conversations and files never leave our infrastructure, and files are deleted after a short time.

Tips for better answers

  • Be specific: “summarize in 5 bullet points for my manager” beats “summarize”.
  • For data questions, name the columns or the exact comparison you want.
  • The chat has memory — iterate! Ask follow-ups and request changes instead of starting over.
