GitHub Copilot code review: Reviews the diff plus instructions files, not the codebase - shallowest context in our comparison.
Greptile: Graph index of the full codebase gives deep cross-file context; ticket/business context is not a focus.
GitHub Copilot code review: Repo instructions (copilot-instructions.md, AGENTS.md, path-scoped files) give basic standards control.
Greptile: Plain-English custom rules on Pro; community reports on default precision/noise are mixed.
GitHub Copilot code review: Copilot spans IDE assistance and PR review, but the review product itself is PR-only.
Greptile: PR-focused; MCP, Claude Code plugin, and one-click IDE fixes exist, but no local review surface documented.
GitHub Copilot code review: No ticket or requirements validation documented.

GitHub Copilot code review: No model choice or BYOK; metered AI credits at model token rates plus Actions minutes.
Greptile: No BYOK or model choice on standard plans; credit billing does not expose model costs.
GitHub Copilot code review: Suggested fixes can be applied via the Copilot coding agent; otherwise comment-only, no follow-up replies.
Greptile: One-click IDE fixes and /greploop iterative resolution with coding agents.
GitHub Copilot code review: No review ROI metrics documented; spend visible only through AI credit consumption.
Greptile: No review-metrics or ROI dashboards documented in the sources we verified.
