01 — Start a session

Set your intention.
Start the clock.

Define what you're going after and what to watch out for. Start the timer and work. Chronicle counts up with color thresholds you set — green, yellow, red — so you always know where you stand.

Take notes as you go. They're autosaved to a Markdown file alongside your check-ins, goals, and summary.

## Notes
Good flow so far. The auth middleware
rewrite is cleaner than expected...

02 — Check in along the way

Your metrics.
Your schedule.

Chronicle prompts you at your own cadence — every 25 minutes, every 45, whatever works. You define the metrics: focus, energy, mood, clarity, or anything else.

Each check-in is a quick pulse. The numbers tell you how. The notes tell you why. Over time, you see what affects your performance and what doesn't.

03 — See the patterns

Every session
is a data point.

Browse your full history. See averages across metrics, total hours, and how things change over time. Filter by date, duration, or scores.

Session 1 is a note to yourself. Session 50 is a dataset. The more you run, the clearer the picture gets.

04 — Reflect on the bigger picture

A journal that connects the dots.

Had a good week? A rough one? Open Reflect, see your sessions side by side, and write about it. Daily, weekly, monthly — whatever scope makes sense.

Your sessions tell you what happened. Reflect is where you figure out what it means.

Weekly reflection
Best week in a while. Energy held up across all sessions. The morning-only schedule is working — afternoon sessions keep scoring lower.

No cloud.
Just clarity.

Plain Markdown
Every session and reflection is a .md file on your computer. Open them in any editor, back them up however you want, or browse them in Obsidian.
No telemetry
Chronicle doesn't phone home, track usage, or sync anything. The only network call is a one-time activation check. After that, everything runs locally.
Yours forever
Your data isn't locked in a database or behind an API. It's files in a folder. Even if you stop using Chronicle, your journal stays.

Built for the long game

It compounds.

Session 1 is a note to yourself. Session 50 reveals patterns. Session 200 with weekly reviews is a body of work you can learn from. Chronicle is designed to get more useful the longer you use it.
