Folio is a local-first digital memory layer. It silently reads, indexes, and shelves everything you capture — so you find it by describing what you remember, not by remembering where you saved it.
We don't struggle to store files.
We struggle to find them.
Every tool assumes you want to act like the librarian of your own digital life — naming things, sorting things, remembering where you put things. Folio removes that burden entirely. You capture. Folio remembers.
Six core capabilities that make Folio feel unlike anything you've used before.
Search by meaning, not keywords. "That idea about distribution I wrote in the car" finds the right file — even if those words aren't in it. Fully on-device. No cloud.
Photograph a handwritten note, whiteboard, or sticky. Folio reads it, indexes the text, and makes it searchable — without changing the original photo.
Dynamic phantom groupings. A physics photo can live on the "physics", "lectures", and "to review" shelves simultaneously, with zero duplication.
Two dedicated features. Speak a shelf name at capture. Or record a full voice memo on the dictaphone UI — waveform, transport controls, red record button.
Your entire memory, arranged by time. Pinch to zoom between year, month, and day. Scroll through everything you've ever captured, instantly.
Index-card format. One title, one body, one shelf. Grocery lists, ideas, references — live alongside photos, voice memos, and PDFs in the same context.
Photo, voice memo, quick note, or shared file. One tap from anywhere. No decisions required.
OCR reads the text. Embeddings encode the meaning. Metadata notes the context. All on your device. Nothing leaves.
A shelf row slides up. Tap one, speak one, or do nothing. Tagging improves retrieval — it never gates access.
Weeks later, describe what you remember about it. Semantic search surfaces the file, ranked by relevance, time, and how often you've opened it.
Your files never leave your device. No cloud sync required. No account needed. The app works fully offline, forever. Trust is earned by design, not promised in terms of service.
No notifications, no nudges, no streaks. Folio works silently in the background while the device charges. You never feel it working. You only feel the result.
You open Folio to capture something you saw, or to write something you thought. Both are first-class reasons. Neither is the afterthought.
Every process — OCR, speech recognition, semantic embedding, search — runs entirely on your hardware. There is no server. There is no account. There is nothing to breach.
Android beta is available now. iOS, Windows, macOS, and Linux are in active development — built on the same Rust core.
