zigxplain.ai

A new kind of developer documentation.
Powered by embeddings, built in Zig, made for codebases that matter.

What if documentation wasn’t just something you write?
What if it was something you ask?

ZigXplain turns Zig projects into their own intelligent assistants.
It extracts structure. Learns semantics. Generates Q&A.
Then builds a reasoning engine that knows your code — because it is your code.

What it does

Trains a language model on your codebase — including symbols, usage patterns, and design idioms.
Indexes your functions into a vector database using rich topic annotations and summaries.
Deploys a local multi-agent system that understands and answers semantically rich questions about your code.
Generates documentation — or replaces it with something better: interactive, conversational, always in sync.

Why we built it

Because explaining code is hard.
Because writing docs takes time.
Because searching source code is still stuck in 1999.
Because language models hallucinate unless you teach them your truth.
Because we wanted a smarter way to ship not just a repo, but an interface to its intent.

Because Zig inspires us.

ZigXplain is written entirely in Zig — not just because it targets Zig projects,
but because we believe Zig is shaping a new generation of software: fast, clear, and fearless.
We hope ZigXplain becomes a tiny part of that story — and a useful tool for those writing it.

The system is waking up

No install guide. No release yet. Just the raw system compiling.
ZigXplain is unfolding in the open — piece by piece, symbol by symbol.
If you’re watching, you already see it.
We’re just getting started.
