Ellipsis is an AI code reviewer that catches bugs and enforces style on every pull request, and can automatically fix what it finds.
Ellipsis plugs into GitHub and GitLab and reviews every pull request like a diligent senior engineer: it flags bugs, security issues and style violations, explains why they matter, and can push fixes directly to the branch. What sets it apart is that teams can define their own review rules in plain English — company coding standards become enforceable checks rather than wiki pages nobody reads.
Ellipsis also handles developer chores such as answering questions on pull requests, generating changelogs and writing summaries for reviewers. Because it learns from the team’s conventions over time, false positives drop as it observes how maintainers respond to its comments.
Teams configure Ellipsis by writing review rules in plain English — things like ‘all database queries must use parameterized statements’ or ‘API responses must follow our error format’ — and the reviewer enforces them consistently on every pull request. It also handles the social layer of review: answering questions from PR authors, summarizing long threads and drafting changelog entries from merged work. Organizations report that automated style enforcement removes a whole category of review comments, letting humans focus on architecture and logic.
Ellipsis offers a free tier for open source and small teams, with paid per-developer plans for private repositories, custom rules and enterprise security requirements.
Engineering teams drowning in review load that want consistent standards enforcement without slowing merges to a crawl.
There is a free entry tier; teams using it on private repositories at scale move to paid per-seat plans.
Ellipsis operates through Git provider integrations and configurable review rules rather than a standalone public API.
Its natural-language custom rules and automatic fixes put it ahead of linter-style reviewers that only report problems.
Ellipsis integrates with GitHub and GitLab, reviewing pull and merge requests automatically and posting its findings and fixes directly in the PR conversation.
