Now in Early Access — AI Code Governance Platform

Every line of code
knows its origin.

Specter gives engineering teams line-level visibility into AI-generated code — deterministic provenance tracking, policy enforcement, security routing, and analytics from prompt to production.

How it Works

From prompt to production — tracked.

Specter wraps the Git AI open standard to capture provenance at the source, then layers governance and analytics on top.

01

Developer prompts AI

When a developer accepts a suggestion from Cursor, Copilot, or Claude Code, the IDE hook calls git-ai checkpoint capturing the exact lines and the prompt that generated them.

# Auto-runs on commit
$ git-ai checkpoint --agent cursor \
  --model claude-sonnet-4-5
02

Provenance stored in Git

Attribution data is stored as Git Notes in refs/notes/ai — inside the repository itself. It survives merges, rebases, squashes, and cherry-picks. No external database to drift.

# Synced on push automatically
$ git push origin refs/notes/ai
✓ Attribution data synced
03

Specter governs & analyzes

Specter's GitHub App reads the notes on every push, evaluates your policy rules, posts a PR comment with attribution breakdown, routes reviewers, and feeds your analytics dashboard.

# .specter/policies.yaml
- trigger: ai_percentage > 80%
  paths: ["src/auth/**"]
  action: require_reviewers

Features

Built for every stakeholder.

From individual developers to security teams to engineering leadership — Specter surfaces the right data at the right time.

Line-Level Attribution

See exactly which lines are AI-generated, human-written, or mixed — down to the agent, model, and prompt. Survives merge, rebase, squash, and cherry-pick.

Automatic PR Comments

GitHub App posts a structured AI attribution report on every pull request within 30 seconds. Reviewers know exactly what they're looking at before reading a single line.

Policy Engine

Declarative .specter/policies.yaml rules with triggers like AI % > threshold, paths match, and models allowlist. Actions include requiring reviewers, failing status checks, or sending alerts.

Org Analytics Dashboard

Track AI adoption trends, code survival rates, agent/model comparisons, and team-level breakdowns. Answer "what is the ROI of our Copilot spend?" with real data.

Review Routing

Automatically assign the right reviewers based on AI content. Route auth/ and crypto/ modifications to security engineers. Load-balance review queues automatically.

ML Fallback Detection

For code pasted from ChatGPT or generated without CLI hooks, Specter's ML classifier identifies likely AI code with a confidence score — clearly labeled as "ML-detected, not provenance-tracked."

Personal Developer Dashboard

Individual developers see their AI usage patterns, code survival rates, prompt effectiveness, and agent/model comparisons. Free tier — no org required.

Compliance Reporting

Generate AI code disclosure reports, audit trails, and license risk reports for regulated industries. Full provenance history for every line of AI code in every release.

Self-Hosted Option

Deploy Specter in your own infrastructure with Docker Compose or Helm. Air-gapped deployments supported. No code content ever leaves your network.

Who it's for

Built for your whole team.

👩‍💼

Engineering Manager

Measure ROI, understand adoption

"Board asks 'what's the ROI of our $500K Copilot spend?' Specter gives me the answer — with real landed-code data, not vendor-inflated accept counts."

🔐

Security Engineer

Route AI code through stricter review

"AI code has different vulnerability patterns — hallucinated APIs, hardcoded secrets, insecure defaults. Specter lets me apply stricter SAST rules to exactly those lines."

👨‍💻

Individual Developer

Understand your AI usage patterns

"I can see which of my AI prompts produce code that actually survives review vs gets rewritten. It's made me dramatically better at prompting."

📊

VP Engineering / CTO

Justify AI tool spend to the board

"Specter's ROI calculator turns AI code volume into dollar value — factoring in survival rate, defect rate, and hourly cost — in a format ready for board presentations."

⚖️

Compliance Officer

Maintain audit trails for AI code

"Finance and healthcare increasingly require disclosure of AI involvement in software. Specter's audit trail and compliance reports have us ready for any regulator."

🌐

OSS Maintainer

Understand contributor AI usage

"When reviewing PRs from contributors, I can see which code is AI-generated at a glance and apply appropriate scrutiny without asking every contributor to self-disclose."

Built by an engineer,
for engineering teams.

Specter was founded because the same question kept coming up: "How much of our codebase is actually AI-generated, and how do we know if it's any good?" No existing tool could answer it reliably.

Built by Sumit Kanwal, Specter sits on top of the open-source Git AI standard to give engineering organizations the governance layer they need as AI-generated code becomes the norm, not the exception.
