# PageIndex vs hindsight

PageIndex and hindsight share 6 technologies: Claude, OpenAI, openai-agents, litellm, MCP, and pillow. Both are written in Python.

- [VectifyAI/PageIndex](https://seerepo.com/r/VectifyAI/PageIndex): 📑 PageIndex: Document Index for Vectorless, Reasoning-based RAG

## Side by side

| | PageIndex | hindsight |
|---|---|---|
| Size | 53,287 lines written, 99 code files | 749,226 lines written, 1,156 code files |
| Who writes it | 5.4% of its commits signed by AI. With Claude Code and GitHub Copilot | 6.8% of its commits signed by AI. With Claude Code, Cursor, Codex, and GitHub Copilot |
| Activity | Last push November 6, 2026, 503 commits, 40,110 stars | Last push November 5, 2026, 4,037 commits, 58,979 stars |
| Tests | 14 test files. 29.3% of its code files have a test that imports them | 1,333 test files. 30.2% of its code files have a test that imports them |

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
