Parallax
Using it
The lenses, the line a sweep leaves in your terminal, and where each part is explained in full.
When a session ends
A Stop hook, an explicit end, or thirty quiet minutes, and the door sweeps the session: it proves the agent’s own edits in a sandbox, reviews the transcript, forks the implementation turn to router-picked seats from other labs, re-runs the proven tests of the other sessions on the same files, runs the lenses below with a proof for each finding, scans for dead code, and delivers. Each step and what it can say is on Sessions.

| lens | asks | proof |
|---|---|---|
bugs | what is wrong that the existing test did not check? | the new test fails without the fix and passes with it; the full-suite result is reported separately |
security | what could an attacker use? Asked together with bugs as one question per shard | the same reproduction, with a severity; a mechanical pass first, free |
perf | a faster, simpler or smaller way? | a benchmark on each side, or fewer branches; suite green |
hygiene | what was left behind? | static first: an edit may only remove or reword, never add a branch or a call; then the suite is green with the cleanup |
drift | which document now says something untrue? | the referent is really gone; a one-line prose fix |
dead code | what does nothing reference? | each removal proven alone and together; no model call |

On a pull request
When automatic PR review is enabled or a review is explicitly requested, one check, Parallax, carries a first pass in minutes and a deep pass after it. Automatic PR review is off by default (PARALLAX_PR_REVIEW=on enables it). Findings carry an evidence state and a confidence. The deep pass offers eligible proven and suite-green patches as one-click suggestions, with at most three inline threads; housekeeping findings remain outside those threads. Admitted patches share one fix PR per review. Unverified and could-not-run findings remain in the summary and console; refuted patches and patches that regress the suite have neither a one-click suggestion nor a fix PR. What each label means, the exact rules, and the sections of the comment are on What a review means.
Memory
A proven finding, a merged fix, or a suggestion you applied becomes a lesson for the repository, and the next session that touches that file is handed it. A suggestion you dismiss becomes a suppression. What a lesson is, what is injected, and how to see the receipts are on Memory.
What it costs
The Parallax app is a monthly plan. Every plan comes with free DeepSeek and GLM (with daily rate limits), uses your own Claude and Codex subscriptions, and can run cloud machines by the hour. Reviews use episode credits: Setup shows your balance and the packs you can add.
A new account gets DeepSeek V4.1 Flash free and 5 free episodes. Each new episode after that uses one Parallax credit when its review starts. Retrying a failed review, fixing its findings, and rechecking the same episode use no extra credit. The free episodes are a lifetime allowance for the account. See Episode credits for your remaining allowance, current prices, and available packs. Parallax credits are separate from Conifer gateway credits.
