Pull request product review
Checks each pull request against product specifications so changes can be compared with the team's stated intent before merge.
Prelint
Prelint reviews pull requests against product specs to catch drift, inconsistencies, and misalignment before release, with repo-based specs and $10 free credits to start.
Overview
Prelint is a product review tool for pull requests. It checks proposed changes against product specifications so teams can catch product drift, inconsistencies, and misalignment before those changes ship.
The product is designed for teams using AI-written code or other fast-moving development workflows where the gap between implementation and product intent can grow over time. The source pages describe product specs living in the repository, reviews happening automatically on pull requests, and findings that help teams revise before merge.
Features
Drift and conflict detection
Flags contradictions, conflicts, and missing alignment across specs and product decisions, not just code-level issues.
Review output on the pull request
Returns inline findings plus a summary comment, with completed reviews counted only after they finish and post results.
Repo-based product context
Treats the repository as the source of truth for product context, with specs stored alongside the code in files such as Markdown or YAML.
Spec-grounded answers
Supports product questions grounded in the spec set, letting stakeholders ask why something works the way it does without interrupting engineers.
Usage-based billing controls
Provides billing controls such as prepaid credits, auto recharge, monthly limits, and free reviews for public repositories.
Use Cases
Review PRs against product intent
Teams can compare each proposed change with the product spec before merge, which is useful when implementation speed makes it easy for intent to drift.
Check AI-written code for drift
Organizations working with AI-generated code can keep a product check in the loop so the agent's changes are assessed for spec alignment before humans review or merge them.
Keep specs and code aligned
Product and engineering teams can use the repo as the shared source of truth for decisions, constraints, and terminology, reducing confusion when multiple contributors move quickly.
Answer product questions from the spec
Stakeholders can ask why a feature or behavior exists and get answers grounded in the stored specs instead of calling a meeting for every question.
Control review spend
Teams watching spend can use prepaid credits, auto recharge, and monthly limits to keep billing predictable while still allowing reviews to continue.
