Chat with the git history of any git repo.

• Built with OpenAI, LlamaIndex, Streamlit and Timescale Vector.
• TSV Time Machine is an example of time aware retrieval augmented generation. Time aware retrieval involves RAG with a retrieval step that searches for vectors that are semantically most similar to a user query and that also fall within a specified time range.
• TSV Time Machine enables you to go back in time and chat with the commit history of any GitHub repository. Each Git commit entry has a timestamp associated with it, as well as a natural language message and other metadata (e.g author, commit, hash etc).

See a live demo of the app here.

• The demo is pre-loaded with the history from PostgreSQL. The demo disables loading data from other git repos. To load data, launch your own fork.
