v0.0.9 · live on npm

Your year of AI pair programming, in receipts.

One install. Every prompt, every model, every dollar — searchable on your laptop. No account, no upload, no telemetry. Local from the first byte.

$npm i -g crixin && crixin install

What it actually does

Local. Indexed. Yours.

Three jobs. No cloud, no SaaS, no second account to forget. Your sessions stay where they live — Crixin just makes them legible.

01

Recall

"Where did I solve that auth refactor?" Sub-second deep search across every Claude, Codex, and Cursor session — with copy-paste resume commands the second you find it.

02

Reflect

How you actually use AI: peak hours, model mix, project distribution, real cost per output token. Numbers you didn't know existed, computed locally on raw BPE.

03

Reveal

An honest behavioral archetype based on your actual sessions — Cowboy, Architect, Debugger, Tinkerer, Prompter-First. Plus an annual Wrapped report when December comes.

The annual moment

Run it once. See your year.

crixin wrapped generates a self-contained HTML report — archetype reveal, hour-of-day heatmap, top projects, est. spend. Local. Shareable as a screenshot. PII auto-stripped.

See what's on the page → The archetypes

A Crixin Wrapped report — 91 sessions, 17,156 messages, 2,744 hours, $27.69 estimated spend, archetype 'Architect', hour-of-day heatmap, day-of-week strip, monthly bars, top projects, source breakdown

How it works

Two commands. That's the whole thing.

No setup wizard. No API keys. No telemetry that magically "helps us improve." The package on npm is the entire product.

# Install + wire MCP into Claude Desktop, Claude Code, Cursor.
$ npm i -g crixin && crixin install

# Open the dashboard.
$ crixin

# Sub-second deep search from the CLI.
$ crixin search "auth refactor"

# Or just ask your assistant: "use crixin to find …"

Per-host install

Pick a host. One click.

crixin install wires all three at once — but if you'd rather install per-host, here's the manual path.

Cursor

One click. Cursor opens a confirmation dialog and writes the entry into its MCP config.

Add to Cursor

Claude Code

One CLI command. Lands in ~/.claude.json alongside any existing MCP servers.

claude mcp add crixin -- npx -y crixin --mcp
Copy command

Codex CLI

Append this block to ~/.codex/config.toml. Codex picks it up on next launch.

[mcp_servers.crixin]
command = "npx"
args = ["-y", "crixin", "--mcp"]
Copy block
