Sillage refers to two distinct open-source projects: a gradient-free memory and test-time learning tool for frozen language models, and a self-hosted private journaling platform for AI-assisted reflection.
The memory tool provides fixed-size associative memory for LMs without requiring gradients or fine-tuning, while the journaling platform offers a private space for daily notes, history, and AI-based Q&A.

Open Source
MIT licensed, free and open source.
Best for
Users requiring private, self-hosted AI-assisted journaling or developers looking to add persistent, fixed-budget memory to frozen language models for verbatim recall.
Not ideal for
Large-scale narrative text generation where high-repetition memory is less critical, or users seeking cloud-based SaaS collaboration features.
A highly specialized, efficient toolset that excels at adding bounded, persistent memory to language models or managing private, self-hosted personal data with AI integration.
Version 1.0.0 for the memory CLI tool was released in August 2026, with ongoing development of the self-hosted journaling platform.
