GitClear attributes every line of code to the model that wrote it via Claude, Cursor, Copilot, Codex, Augment or Gemini. Then durable output is scored against rework, defects, review time, and more.

One comprehensive scorecard. Ten minutes to get started. No sales call required.

Diff Delta is lineage-aware: moves, renames and reformatting keep their lineage, so code the developer rewrites stops counting toward the model.

Databricks data engineering

Your bronze tables already hold the answer. We build the tables that relate it.

GitClear specializes in enriching Databricks bronze tables — raw AI assistant telemetry, git history, pull request events, issue trackers — into the silver and gold tables that relate facts nobody could join before: which model earned its inference spend on which kind of task, and how much of its output was still in production 90 days later. The two panels at the top of this page are those tables.

We build these pipelines on Apache Airflow with Astronomer, the same orchestration we run for billion-dollar enterprises. Bronze ingest → silver work episodes → gold marts, rebuilt nightly in Unity Catalog, against your own warehouse — your data never leaves your Databricks account.

  • Medallion modeling (bronze → silver → gold) in Unity Catalog, with lineage that survives an audit
  • Containerized, idempotent Airflow DAGs on Astronomer — backfill a year of history without babysitting it
  • Diff Delta as the unit of output, so moves, renames and reformatting never inflate a model's numbers
  • Episode-grain facts, so cost, durability and revision risk can all be asked about the same row
The product

Four surfaces. One defensible ROI score.

Every AI stat in GitClear originates from deep analysis of code changes — so when a number doesn't look right, you can always drill into the code that produced it.

01 · Line-level attribution

Every line tagged with the model that wrote it.

GitClear cross-references your Git history with vendor AI usage APIs and agent telemetry hooks to produce commit-grade provenance — no guessing, no aggregate estimates.

  • Claude, Copilot, Cursor, Codex, Augment and Gemini APIs supported out of the box
  • Attribution precision maximized via telemetry hooks
  • Access via a robust API, for your own analysis or internal reporting

02 · AI hotspot directories

Find the folders where AI is creating more work than it saves.

Not every directory responds to AI the same way. GitClear surfaces the folders where AI-assisted code has elevated defect and duplication rates — so you can coach, gate, or restrict tool access before it compounds.

  • Per-directory AI %, defect Δ, duplication Δ
  • Risk score normalized against your own baseline
  • Exportable as quarterly engineering review artifact

03 · Cohort comparison

See human vs. LLM code, measured by the same yardstick.

GitClear's Diff Delta metric works the same way whether a line came from Claude or a senior staff engineer. Compare durable change velocity, rework rate, and review time across cohorts — without apples-to-oranges caveats.

  • Cohort views by team, repo, or AI tool usage level
  • Side-by-side weekly trends — AI power users vs. non-adopters
  • Statistical significance flags on every delta

The methodology

Inspired by Google DORA. Built for the AI era.

Three inputs, one defensible number — so finance, your board, and your own engineers can all read the same scorecard without arguing about what it means.

01

Attribution

AI usage APIs plus commit heuristics plus agent telemetry hooks — not survey estimates. Every line traceable to the model that wrote it.

02

Output quality

Diff Delta quantifies durable change vs. churn. Human and LLM code measured with the same metric, across the same time window.

03

Developer experience

Self-reported hours saved and satisfaction scores. Productivity gains don't count if your best engineers are walking.
