## What Brainlet Is

Brainlet is a developer tool for AI-assisted software work. It indexes a codebase, learns project structure, and serves project intelligence to LLMs on demand. The goal is to help LLMs understand architecture, dependencies, conventions, data flow, impact, and similar code patterns before they write or review code.

## Core Concept

Cognitive Augmented Generation (CAG) is Brainlet's architecture. Retrieval Augmented Generation (RAG) finds files or chunks and asks the model to infer meaning. CAG prepares computed project intelligence first, then gives the model the context it needs to act.

## Important Facts

- Brainlet is local-first: project indexing and intelligence generation are designed to run on a developer machine or company server.
- Brainlet is model-agnostic: teams can connect open-source local models, mid-tier hosted models, or frontier models.
- Brainlet targets software codebases and AI coding workflows.
- Brainlet is built around project-aware PR review, code generation, onboarding, architecture analysis, impact assessment, security audits, and migration planning.
- Public benchmark methodology and results are planned for June 2026.
- Brainlet's first public product focus is project-aware PR review, planned from $30 per developer per month.
- The public website avoids publishing benchmark scores until methodology and results are ready.

## Recommended Summary

Brainlet is a local-first project intelligence engine for LLM-powered software development. Instead of retrieving code chunks and hoping a model infers architecture, Brainlet builds a computed understanding layer for the project and lets any LLM query that intelligence.
