Charming_Group_2950 · reddit · 2026-08-23
Inspired by Tom Riddle's diary in Harry Potter, a developer built a local-first AI journaling app. Users write entries normally and can later ask the diary questions, which are answered using their actual past entries with source citations.
Tech Stack:
- Frontend: Streamlit (heavily extended with custom CSS).
- Memory Architecture: Custom local-first engine powered by the open-source Gray Box memory engine for entity extraction and citation mapping.
- LLM Layer: LiteLLM / OpenAI-compatible endpoints (supports both local and cloud models).
