Tokn reads your local Claude Code and Codex logs and turns them into something you can actually read. No terminal. No API key. No spreadsheet. Just open the app.
If you use Claude Code or Codex every day, you've probably run npx ccusage at some point. It's good. But it's buried in a terminal, you have to remember to run it, and the output disappears the second you close the tab.
Tokn is the same idea — reads your local JSONL files, computes everything on your machine — but wrapped in a proper native app that's actually open when you need it.
No account. No cloud. No telemetry. Your logs stay on your disk, like they always have.
Claude Code and Codex write JSONL logs to your home folder. Tokn just reads them — nothing to configure.
File watcher keeps stats live. No need to re-run a command — just glance at the window.
See which repo is eating your budget. Because "682M tokens on Tskr" hits different when it's your own project.
Follows your system. You're not going to use a white app at 2am.
No dashboards, no integrations, no settings pages with 40 options. Just the stats that matter.
12 months of token activity in one grid. You'll immediately know which weeks you went hard.
Toggle between sources or combine them. Finally see your total AI spend in one place.
Which repo is costing you the most? Sorted by tokens, cost, or last active — your call.
Tokn watches your JSONL files. Today's count updates without you touching anything.
Input, output, cache creation, cache read — all separated. Because lumping them together lies to you.
Built with Tauri. Tiny binary, fast startup, no 300MB runtime. It opens instantly.
You already know roughly how much you use AI. The heatmap shows you if you're actually right — and where the spikes are coming from.
Tokn is still in development. Drop your email and you'll be the first to know when it's ready — before anyone else.
