AI apps that don't sell
you out.
We build cutting-edge AI for the problems modern life actually throws at you — engineered on Apple Intelligence, so your stuff stays yours and never touches our servers. No accounts. No ads. No creepy data grab.
Hard problems. Sharp tools.
OctoSlice is an independent studio pushing Apple Intelligence as far as it will go — focused, private-by-design apps built for challenges that deserve better software.
Practical AI
Every feature has to earn its spot: save you time, kill confusion, or make the important stuff easier to act on.
Private by design
We skip accounts, tracking, ads, and needless cloud whenever a feature can run right on your device.
Built to grow
A whole portfolio is planned across study, organization, and everyday AI — Semester is just app #1.
Semester
Drop in each class syllabus once and Semester builds your entire term — then works it with you, every week until finals. Your whole semester, sorted.
- An AI for your whole semester — plus one for every class, and one for every group session.
- Calendar, reminders, and to-do lists — for you and your study group — built from the syllabus, not typed in.
- Flashcards, recaps, and cited answers from your material: PDFs, Word docs, typed notes, handwritten pages, lecture recordings.
- Listen instead of rereading — audio playback of your notes, or a two-voice, podcast-style review of any topic.
- Share notes, decks, and recaps with classmates — and with professors who have the app.
- Every answer cites your material — it never invents a date. And when your documents can't answer, it drafts the email to your professor, then saves the reply as a new source.
“What’s on the midterm for HIST 101?” — answered from your notes, with sources.
Your notes.
Your phone.
Nobody else's business.
Most study apps ship your work to their servers. We don't. Where a feature can run on your iPhone, it does — so the sensitive stuff never has to leave.
- Processed on-device with iOS frameworks & Apple Intelligence where available.
- No servers of ours receive your app content.
- We never sell or share personal info. Ever.
