tenk

Talk to SEC filings with AI

Ask questions about 10-K and 10-Q filings, get answers with citations

What is tenk?

tenk lets you have a conversation with SEC filings. Instead of manually reading through hundreds of pages of 10-K and 10-Q reports, just ask questions in plain English and get answers with direct citations to the source.

Why not just use ChatGPT?

You could copy-paste filings into ChatGPT, but:

• 10-Ks are 100+ pages - you can't paste them all
• You definitely can't paste multiple filings to compare companies
• You'd have to manually find and download each filing first

tenk automates all of that. It fetches filings from SEC EDGAR, indexes them locally, and lets you query across multiple filings at once.

Features

• ✅ RAG over SEC filings with a local vector database (10-K, 10-Q)
• ✅ Auto-downloads filings from SEC EDGAR
• ✅ Citations with links to source documents
• ✅ Stock data via Yahoo Finance
• ✅ Web search for data not in filings
• ✅ Excel generation for tables and financial models
• ✅ Export answers to PDF, DOCX, or Excel
• ✅ Conversation memory with auto-summarization

Requirements

• Python 3.10+
• OpenAI API key (set OPENAI_API_KEY environment variable)

2. Download & index - Downloads filings and chunks them into a local vector database
3. Semantic search - Finds relevant passages using sentence-transformers
4. AI analysis - Generates answers with citations
5. Export - Optionally export to PDF, DOCX, or Excel
