Watch any codebase explain itself.

Drop in a GitHub URL. Lenzon reads the repo, picks what matters, and hands back an animated walkthrough narrated, paced, and scored for whichever human you need to bring along.

Sample from Focus Brief analysis of github.com/facebook/react.git

Three acts

Quiet on set. We point at your repo and roll.

Lenzon splits the work the way a film crew would. A fast scout reads the shape of the project. You pick the story. Writers, producers, and directors craft the scenes and the detail is brought to life.

Scout the repo

Our scene scout quickly reads the repo. It comes back with the major subsystems, entry points, and what looks load-bearing.

Choose the angle

Overview, focused-brief, scorecard, or walkthrough. Pick a lens and a depth. Only the parts you care about get read deeply.

The player renders code, state and data diagrams, motion and deep analysis with narration tuned to your audience.

What you get

A narrated walkthrough, not a pile of notes.

  • A paced, narrated presentation with real code on screen, highlighted line-by-line where it matters.
  • Tunable audience factors — so the same analysis can brief an exec or onboard a junior developer.
  • Re-render on demand. Change audience, pace, or persona without re-reading the repo.
Credits, not subscriptions

Pay only for the runs that land.

Buy a bundle of Credits. Each operation: triage, analysis, script, voice has a transparent per-credit cost. If a run errors out, you don't get charged. Private-repo analysis is included with every paid pack.
