Pricing and conditions
Documented terms
Listed monthly prices: Free $0/25k tokens; Pro $19/200k tokens. PR counts are estimates, not guarantees. Higher-button tier prices, currency code and tax were not verified. No rollover or automatic plan upgrade; exhaustion means wait or choose an upgrade. Paid subscriptions renew and are generally nonrefundable subject to legal/discretionary exceptions; a card-backed trial may auto-charge when it ends.
Pricing source read:
Pricing or terms sourceCode, model and service licensing
Proprietary service; its open-source page describes sponsorship, not source licensing. Terms reserve platform IP and assign feedback rights. The FAQ says neither it nor providers store code/diffs or train on them; this was not independently audited. Account/usage data still has separate analytics, sharing, transfer and retention rules, so do not infer all-data zero retention or cleared output rights.
Basis and limits of the recorded score
Original 4.4/5 retained; the original scoring worksheet and hands-on evidence are unavailable. This documentation review did not re-score it.
Overview
Its documented role is change explanation and communication, including weekly reports and a public changelog API. Suggested refactoring is not proof of correctness, vulnerability detection or secure production code. It reads diffs and produces written summaries; it does not run the code, so a summary is only as reliable as the diff and commit metadata supplied to it. Confirm which repository hosts, model providers and output channels a given plan supports before relying on it in a release process.
