denoise

Review code you didn't write.

Code diffs for the agentic pace.

Six zoom levels, and the line you were reading stays where it was. Focus a function in a file or a pull request, starting from the most complex. On a phone the controls are icons.

See it on a small change

The call didn't change. What guards it did.

A line diff shows one deleted line, and save(record) looks untouched. denoise reads both versions of the function and says what happened around that call. Select the finding to see where.

Flow changes

  • Early return removed before save(record).

A structural observation, not a verdict: denoise does not say whether the change is right. It is read from the code with a parser, with no AI and no guessing. How it works and what it skips

Schematic · What does it do, step by step, in plain words?

update(allowed, record)
returns early if !allowed return
end
update(allowed, record)
returns early if !allowed return
save()
end
calls save
2export function update(allowed, record) {3  if (!allowed) return;4  save(record);5}
update(allowed, record)
returns early removed if !allowed return
update(allowed, record)
returns early removed if !allowed return
save()

This example is a three-line function, read when this page was built by the same engine the app runs. Try your own pull request, public ones work without signing in.

Deterministic

Same commit, same picture. 0 failures across 70,811 functions in 22 real repositories: no crashes, no drawings that broke their structural rules, no redraws that differed. This does not test that a drawing is right.

Built for agents too

The same trees and diffs as versioned JSON, from the CLI or in CI.
