Kronux dashboard - time blocks, raw logs, taxonomy

Built for people who think differently

Kronux doesn't assume one taxonomy fits all—your workflow, your rules.

  • Powerful default that works out of the box
  • Bend it: tell the AI "ACME = work" or force keywords into categories
  • Fully editable taxonomy tree—your rules override the model
  • One click re-runs your entire history; your data is never lost

Frequently asked questions

Everything you need to know before trying Kronux.

Can I try Kronux before buying?

Yes. Download the free trial and use Kronux for 14 days with no credit card required. When you're ready, pay $29 once to unlock it forever.

Does Kronux work offline?

Fully. Kronux tracks your active windows locally, stores everything in SQLite on your Mac, and classifies activity using Ollama's Llama 3.2—all without an internet connection. No cloud, no sync, no accounts.

Where does my data go?

Nowhere. Your time logs, database, and AI model run entirely on your Mac. Nothing is uploaded. No API calls, no telemetry, no third-party servers. Sensitive apps like 1Password have their window titles stripped before logging.

Can I export my data?

Yes. Export to CSV, JSON, or match time blocks to tasks from ClickUp and Jira. Your data lives in standard formats—backup, migrate, or use it however you like.
