Your calm
study desk.
Deadlines, tasks, and instant flashcards from your notes. Free, private, remembers you.
See it in action.
Your deadlines counting down and flashcards made from your notes — right here.
Change the weather.
Slide from a glassy calm to a full storm. Wind tilts and whips the crests; the whole sky answers.
Or just breathe.
Calm mode slows the sea to a deep swell and guides your breath in and out with it. Set a timer, close your eyes between cues.
Why TIDES exists.
Study tools shouldn't cost money or sell your notes. The big "AI study" apps lock flashcards behind a subscription and upload everything you paste to their servers. TIDES is the opposite on purpose.
Free, no profit
No paywall, no account, no ads, nothing to buy. Built for students, given away. That's the whole point.
Private by design
Your notes, deadlines and grades live on your device only — never uploaded. Paste a whole chapter; it never leaves your laptop.
Works offline
Add it to your home screen and it opens instantly, even with no signal — a calm desk that's always there before a test.
Made by a student, for students. If it helps you pass something, that's the only return we're after. Share it with a friend — it's free for them too.
Why an ocean?
Studying is stressful; most study apps feel like spreadsheets. TIDES wraps the work in something calm — a living sea that reacts to you, shifts with the weather and time of day, and slows to a breathing guide when you need it. The ocean is the feeling. The desk is the tool. Play with it below.
Set the mood
Four times of day and calm-to-storm weather recolor the whole sea — pick what helps you focus.
Breathe when it's a lot
Calm mode slows the water and paces your breath in and out, with a quiet timer. Two minutes resets your head.
Optional sound
A soft focus drone and a satisfying timer tick — synthesized, no files. Off by default; on when you want it.
Built by a student. Ships as one small self-contained page — no trackers, no build, nothing phoning home.
