FOR THOSE WHO STILL THINK CODE MATTERS

Enjoy reviewing
code again.

A judgment that stays yours.

Difflane routes attention through large changes so you can focus on the code that deserves judgment.

services/payments/src/ledger/reconcile.ts

MAIN  ←  FEATURE/SETTLEMENT     7 / 12 REVIEWED

86export async function reconcileTransfer(transfer: Transfer) { 87  const entry = await ledger.load(transfer.id); 88  await ledger.apply(entry, transfer.amount); 89  await settlement.enqueue(transfer.id); 90  await audit.record(transfer.id); 91}

02 / THE PROBLEM

Large reviews hide
what deserves judgment.

An 80-file pull request makes every file look equally urgent. It isn’t.

80 CHANGED FILES

SOURCE ORDER

Source order. Every file has equal visual weight.

  1. pnpm-lock.yaml+2,412  −1,008
  2. packages/api-client/src/generated.ts+1,804  −1,772
  3. tests/fixtures/payment-events.json+390  −390
  4. db/migrations/enforce_ledger_balance.sql+84  −12
  5. services/payments/src/ledger/reconcile.ts+47  −19

ONE FILE NEEDS JUDGMENT. THE LIST DOESN’T SAY WHICH.

03 / ATTENTION, ROUTED

Your attention,
best used.

Difflane brings the files that need judgment forward. Everything else stays within reach.

THE ORDER IS VISIBLE. THE REASON IS EXPLAINABLE.
  1. 01HIGHER ATTENTION12 files

  3. 03TESTS23 files
  4. 04GENERATED14 files

THE AI POSITION

We don’t outsource judgment.

AI is already everywhere in the development pipeline, even where it should not be. Production systems deserve accountable decisions.

Today, Difflane does not use LLMs to decide what matters. If that changes, any AI features will be explicit, optional, and accountable. They will not replace reviewer judgment.

04 / PRODUCT PROOF

Know why a file matters
before opening the diff.

The route and its reason remain visible while the code stays central.
