Project context for AI coding

Stop letting AI assistants guess your codebase.

cix gives AI coding tools a live index of your project so they can understand symbols, dependencies, schemas, and impact before generating code.

Support for Claude Code, Codex, and Gemini CLI.

01 — WHAT CIX DOES

Without cix / With cix.

The patterns on the left are not rare — they happen quietly on every long session, in every large repo. cix doesn't force a better outcome; it gives the model a structured alternative to search and guesswork: a queryable index of what your repository actually contains.

Without cix

With cix

Guesses how data is structured

→ Can inspect indexed schema definitions

Searches many files for relationships

→ Can query indexed symbols and dependencies

Estimates rename impact manually

→ Can trace callers and references

Rebuilds context repeatedly

→ Can use a persistent project index

Has limited visibility across repositories

→ Can navigate indexed relationships across repositories

02 — PRIVACY

Your code stays yours.

Your code is indexed into a private index scoped to your account. The only people who can read a repository's index are verified collaborators on that repository — people who already have access to the code on GitHub. We don't train models on your code, sell it, or share it outside the disclosed sub-processors. Indexed code is deleted within 30 days of disconnect or cancellation.

03 — EXAMPLE

What it looks like in practice.

Your assistant queries the index before it writes. The output is symbols and edges, not arbitrary chunks. The same loop applies to every workflow that follows.

04 — CROSS-REPOSITORY

Understand one repository or twenty.

Most AI coding tools operate within a single repository. cix can help navigate relationships across multiple repositories, making large systems easier to understand and change safely.
