Buildermark is an open-source, local-first desktop app that measures AI contribution across your codebase by matching agent diffs to commits. It supports Claude Code, Codex, Gemini, and Cursor, producing a breakdown of which files, functions, and commits involved AI generation — all without sending code to external servers. A browser extension handles import from cloud-based agents, and a Team Server edition for org-level aggregation is planned as a paid self-hosted offering. The tool surfaces metrics like percentage of total lines AI-generated, AI contribution by file type, trend over time, and breakdown by agent (which AI wrote what). For solo developers it's a personal diagnostic; for teams, it becomes a code quality signal — sections with high AI contribution may warrant extra scrutiny in review. Buildermark taps into a growing enterprise need: as AI-generated code becomes the norm, teams, auditors, and compliance officers want provenance data — both for quality assurance and for emerging legal questions around IP ownership of AI-generated work. GitHub doesn't expose this natively, and most agent tools don't track it. Buildermark fills that gap with a zero-cloud approach that enterprise legal teams can actually approve.

GitHub Copilot Workspace is an AI-powered development environment that turns issues into code changes using a plan-implement-verify loop. Works directly from GitHub issues.
Reviewer scorecard
“Unified attribution across Claude Code, Codex, Gemini, and Cursor simultaneously gives me something no single agent tool provides. Commit-level AI attribution is genuinely useful before merging — I want to know if a section is heavily AI-generated so I can give it proportionally more review attention.”
“Issue-to-PR workflow is the right abstraction. The planning step prevents the 'just generate code' antipattern.”
“Most AI-assisted code is human-modified before commit, creating a false dichotomy between 'AI-written' and 'human-written.' The legal question of IP ownership for AI-generated code is also unresolved, so Buildermark's framing could create more confusion than clarity for compliance teams. Wait for the enterprise edition.”
“Still limited in what it can handle. Works for straightforward issues but struggles with anything architecturally complex.”
“In 18 months, enterprise procurement will ask for AI contribution reports the same way they ask for test coverage reports. Getting a baseline now builds the historical data that future audits will require — and Buildermark's zero-cloud architecture means early adopters won't have to migrate when compliance requirements arrive.”
“This is where all development is heading — describe what you want, AI plans and implements. GitHub has distribution advantage.”
“Having a dashboard that shows my AI usage patterns across projects would genuinely change how I think about skill development. Am I outsourcing the hard parts? Am I improving? Buildermark is the mirror I didn't know I needed — and the fact that it's free and local means there's no reason not to try it.”
