CodeBlendInsights about AI assistance in your code (formerly AI Contribution Tracker) Installation Launch VS Code Quick Open ( Ctrl+P), paste the following command, and press enter.Copied to clipboard |
CodeBlendPrivacy‑friendly code analysis extension that estimates how much of your code is AI‑assisted (inline accepts, pastes from AI chat, Copilot, etc.) versus manually typed. It classifies every insertion in real time and visualizes attribution per line & per session. Available for VS Code, IntelliJ IDEA, and Android Studio.

| Command | Purpose |
|---|---|
| Sign In / Switch Account | Acquire / switch Microsoft account & verify ingest rights |
| Reset Current Session Stats | Start fresh session; snapshot previous |
| Manual Submit If Commit Changed | Force boundary if commit advanced |
| Show AI Edit Characters | If per‑character trace enabled: opens virtual doc with historical AI spans; else toggles line style between previous and char for live spans |

Enable per‑character historical attribution (extra memory) |
aiTracker.maxTrackedDocChars |
200KB |
Max per-document size (in KB) to attribute; files above are ignored (range 1–1024KB). Legacy byte values auto-mapped. |
aiTracker.maxCheckpoints |
100 |
Max number of recent attribution checkpoints retained for fast restore (minimum 50, no explicit upper cap). Older ones dropped FIFO. |
Marker semantics: bright = fully AI line, light = mixed line, none = no AI characters. In char mode, a subtle background highlights contiguous AI character spans (merged). Safeguards:
- Spans merged (never per char) & capped (~5k) else fallback to line mode.
- Dense high‑AI very large files auto fallback.
- Debounced updates share line highlight timing.
Data Upload & Privacy
This plugin only records repository and commit metadata—no personal data is collected. Microsoft login is needed to upload data. For details on collected data, visit HowItWorks.
The limited data described below is uploaded solely to understand overall AI assistance usage patterns. It is not intended or suitable for individual performance evaluation, and no personal identity or prompt content is collected.

FAQ
How is AI % computed? (likelyAi + pasteFromCopilot + pastelikelyAi + pastepossiblyAi + fallback) / totalCharacters. ignoredCharacters are excluded from both numerator and denominator.
