AI Agent That Works With Your Files
Upload a PDF, spreadsheet or Word file, describe the job, and the agent reads it, looks things up on the web with sources, and hands back the finished file.
What Is an AI Agent?
An AI agent is an AI model that does more than answer: it works through a task in steps, uses tools such as file reading and web search, and checks its progress until it can hand back a result. On YesChat the agent is available on every plan. Start in the box above or in the YesChat chat; each task is saved to your chat history, so you can come back and continue. If you only need quick answers, the AI chatbot is the simpler place to ask, and the YesChat home page shows everything else YesChat offers.

What the AI Agent Can Do for You
Read PDFs and documents
It summarizes long PDFs with page references, pulls out deadlines, figures and clauses, and answers follow-up questions about the text.

Research the web with sources
When the answer has to be current, it searches the web and lists the sources it used, so you can check each claim yourself.
Work with spreadsheets
It cleans and summarizes Excel or CSV data, builds charts and explains what changed. More on the AI Excel page.

Return a finished file
It drafts slides with speaker notes as an editable .pptx, writes and edits Word documents, and gives you the file to download. See the AI presentation maker.
