Pile

Pile is a desktop journaling tool that focuses on personal reflection and the development of thoughts. Users create a “Pile” to capture short entries, edit or delete them via timestamps, and highlight specific notes for later review. The interface supports burst‑style journaling, allowing ideas to be recorded quickly and revisited over time.

The application runs on macOS (both Apple silicon and Intel) and Windows, and it is distributed under an MIT license, making it free and open‑source. It stores entries locally, emphasizing privacy while offering optional integration with AI services.

If an OpenAI API key with GPT‑4 access is provided, Pile can generate AI‑driven reflections on the user’s entries, adding a layer of automated insight to the journaling process.
