## What is Sediment?

Short lines settle into the grain of a week, the shape of a month, the story of a year. Sediment is a quiet archive built for stacking, not writing.

— You don't have to write well
One line is enough. So is one photo. Don't arrange your thoughts. Leave them as they come.

— Time does the sorting
After seven days, your first weekly layer is woven. Four weeks make a monthly. Then quarterly, then yearly. Scattered fragments find their place.

— AI traces the grain
Recurring currents, moments of change, words appearing for the first time — Google Gemini AI points them out. You spend less time looking back. Sediment is not a substitute for medical or psychological care; it offers observation only.

— Start anonymous
No email, no name asked. Like it? Link an Apple, Google, or email account later. Your fragments come along.

— It's yours
Your fragments belong to you. We just hold them for a while. Export or erase everything anytime. No ads, no tracking, no data sales.

Features
• Text + photo fragments (short, often)
• Today timeline + streak counter
• AI Chronicles — auto-generated weekly / monthly / quarterly / yearly layers
• AI-assisted one-liner — for days when words won’t come
• Korean, English, and Japanese

50 credits per month are refilled automatically, free. Sediment Pro unlocks unlimited weaving for those who write more.

What settles, stays.
