See exactly how you use
AI coding assistants.
Analytics for AI-assisted development. Explore how AI shapes the way you build.
You can't improve what you don't measure.
Developers estimate they work 20% faster with AI but controlled studies show the opposite.
METR, 2025The average developer juggles multiple AI coding assistants with no unified view of impact.
JetBrains, 2025Most engineering orgs are spending on AI tooling without any data on what's working.
Jellyfish, 2025Adoption is near-universal. Measurement is not. The gap between spend and insight is growing.
Jellyfish, 2025Everything in DiffDive Lite
A complete local analytics tool built around the data your AI tools already generate.
Auto-discovery
Scans your machine and finds all AI assistant chat history automatically. No file paths to configure.
Session browser

Model analytics
See which models you use, how often you switch, and how model usage shifts across projects over time.
Activity heatmap
Day-of-week by hour-of-day breakdown reveals your peak AI-assisted hours and usage patterns.
Workspace insights
Per-project breakdown of AI usage, session frequency, and interaction patterns across all your workspaces.
Code impact
Lines added and deleted, files edited, edit density per session. Understand where AI actually moves the needle.
