AI Document Assistant for Live Meetings — RAG + Whisper
Upload your documents before the meeting. Ask questions during the call. CFAI surfaces the answers from your files in real time — locally, without any cloud upload.
What If You Could Ask Your Documents Questions During a Live Meeting?
Information retrieval during meetings is a common failure point: you know the answer is in a contract, a previous email, or a spreadsheet — but finding it quickly while the conversation continues is hard. Most people either interrupt the call to search, admit they'll follow up, or miss the moment entirely.
CFAI's Document RAG (Retrieval-Augmented Generation) changes this. Before your meeting, upload any document: a PDF contract, a Word doc, a CSV spreadsheet, a markdown notes file. During the call, ask CFAI in natural language — 'What were the agreed deliverables in the Q1 contract?' or 'What was the budget figure from last week's proposal?' — and CFAI surfaces the answer from your documents within seconds.
Everything runs locally on your Windows PC. Your uploaded documents are processed and indexed on-device using a local vector store. No document content is sent to external servers. Combined with real-time Whisper transcription and the Cognitive Map, CFAI becomes a live knowledge retrieval system for every meeting.

How to Set Up Real-Time Document RAG for Your Meetings
Upload Documents Before the Meeting
Before your call, open CFAI and upload your relevant documents: contracts, proposals, previous meeting notes, product specs, or any PDF/Word/CSV/JSON file. CFAI indexes them locally.
Start the Meeting
Join Zoom, Teams, Meet, or any platform. Activate CFAI's transcription and Document RAG mode. As the conversation runs, CFAI listens for questions that your documents can answer.
Query Documents Mid-Call
Type or speak a question into CFAI: 'What was the agreed price in the contract?' CFAI searches your uploaded documents and returns the relevant passage in seconds — without interrupting the call.
Build a Knowledge-Rich Transcript
After the meeting, your transcript includes both what was said and what CFAI retrieved from your documents. The Cognitive Map shows how discussion related to your document content.
Frequently Asked Questions
What is Document RAG in CFAI?
Document RAG (Retrieval-Augmented Generation) lets you upload documents before a meeting — PDFs, Word files, CSVs, markdown. During the call, CFAI retrieves relevant content from these documents when you ask questions. Everything is indexed and queried locally on your Windows PC.
Can I query a PDF during a live meeting?
Yes. Upload the PDF to CFAI before the call. During the meeting, ask any question about the document — CFAI finds and returns the relevant passage in real time, without uploading your PDF to any external service.
What file types does CFAI's Document RAG support?
CFAI supports .txt, .md (markdown), .pdf, .docx (Word), .csv, and .json files for Document RAG. Files are processed and indexed locally using a local vector store.
Does CFAI send my documents to the cloud?
No. Document indexing and retrieval run locally on your Windows PC. Your document contents are not uploaded to CFAI's servers. If you configure a cloud LLM, the LLM receives text queries but not your full documents.
How is CFAI's Document RAG different from Microsoft Copilot?
Microsoft Copilot requires a $30/user/month M365 add-on and only works within Microsoft 365 apps. CFAI's Document RAG works in any meeting on any platform, processes files locally, and costs €7.99/month with no platform lock-in.
