Specify, understand, and ship demanding software — with AI.
Code Explorer turns an unfamiliar codebase into something you can reason about, document, and change with confidence. Spec-driven development meets a code intelligence engine that does the static analysis for you.
Two jobs, done properly. Understand any codebase through a prebuilt graph of symbols, call chains and clusters — no more grepping in the dark. And build with AI on a foundation that holds: functional specifications, project memory, hunk-level changelists, and an integrated Git client, all in one place.
Understand any codebase
The static analysis is already done. Tree-sitter ASTs, a full call graph, dependency edges and Leiden clusters are indexed up front, so navigation is instant and exhaustive.
- Jump from any symbol to its callers, callees and definition
- Trace a call chain across files in the graph view
- See how modules cluster — and where the cycles hide
Build with AI
Demanding, specification-driven development needs structure that survives. Code Explorer gives the work a spine:
- Specs — URS → FS → TC chains, anchored to symbols, with coverage and traceability computed for you
- Project memory — phases, plans, decisions and summaries that answer why, not just what
- Changelists & Git — hunk-level staging and an integrated client, so intent stays legible in history
Local, private, fast
Everything runs on your machine. The index is built once and cached; queries are answered from it in milliseconds. Your code never leaves your laptop.
Who it's for
Whether you're reading code, learning it, or building it — Code Explorer keeps you in control of systems too large to hold in your head.
Reviewers
Read a change's intent, not just its diff. Trace what it touches, why it exists, and which spec or decision it answers — before you approve it.
Onboarding
Understand an unfamiliar codebase in hours, not weeks. The graph and project memory hand you the structure and the why on day one.
Large-codebase analysis
Navigate, cluster and reason about systems that no longer fit in one person's memory. Cycles, hotspots and dependencies, made visible.
Professional builders
Stay in full control, but stop typing every line. Concentrate on what matters — the what and the why — and let the AI handle the how, with every decision on the record.
This isn't vibe coding. It's professional software development brought up to date — you decide what and why, the AI handles the how, and nothing is left undocumented.
