second-brain-lite
A lower-compute second brain that searches your files fast and turns useful context into interconnected semantic wiki elements.

second-brain-lite is the faster, lighter path to the same end: helping AI recover the context already present in your work. It searches the material directly, then creates the semantic connections that make it useful.
How it works
- Find the right source fast. It uses rg (ripgrep) and grep to search source files directly and surface the material relevant to a question.
- Create semantic wiki elements. It turns what it finds into focused wiki elements and connects them around the key concepts, people, decisions, and projects in your work.
- Keep the cost down. By focusing on source search and semantic synthesis, it reaches the same useful retrieval outcome with less time and compute.
How it differs
The full second-brain maintains a cited, self-updating knowledge system. second-brain-lite narrows the path to the two things that matter most for lightweight use: finding the source and creating the semantic links. Same job, less machinery.
