Vetoo
Greptile Review modelA panel of specialist agents reviews every PR in parallel, reconciled into one ranked verdict. Interactive by design: reply to any finding and get answers in thread. Long-term memory learns your team’s preferences across reviews.A swarm of agents reviews each PR against a prebuilt codebase graph, tracing git history to understand why code was written a certain way.
LLM providersVetoo leads on this dimensionMultiple models, including frontier ones, weigh in on every diff, so no single model decides the review.Reviews run primarily on Anthropic’s Claude, via the Claude Agent SDK, a single-provider pipeline, not a multi-provider panel.
Cross-repo contextVetoo leads on this dimensionClones every repository your change depends on and searches sibling repos for callers it could break, on every plan and with no cap on linked repositories. Workspace wiped when the review ends.Indexes a whole repository for deep context and can pull related repositories in as read-only context; tuned for single-repo and tightly-coupled repos.
Source code retentionVetoo leads on this dimensionZero retention by design: your code is processed only for the review, encrypted, then deleted the instant the verdict lands. Never stored, never trained on.Builds and continuously updates a persistent index of your codebase (code and embeddings), so a long-lived copy is stored, not just the diff.
Bring your own keysBring your own Anthropic key on Enterprise to run reviews on your own model spend as you scale.Managed models on its cloud, with bring-your-own-LLM on the self-hosted tier.
