About

Etch

Features
Read full description

Etch is a place for the things you want to remember. It sits somewhere between a notes app and flashcards: quick to capture, gentle to revisit, without the pressure of a study app. Capture in whatever way is fastest. Type a quick note, dictate it with your voice, or clip a passage while you read. In Safari, select the text and send it with the Share button in the toolbar, and Etch keeps both the passage and a tappable link back to its source. Every card is either a simple fact or a question with an answer. A question gives you a small moment of recall before you reveal the answer, which is what makes revisiting feel like reminiscing rather than testing. Revisit a handful at a time, whenever you feel like it. No streaks, no due dates, no counts piling up. You come back to what you saved because you want to, not because an app is nudging you. Optional on-device AI. On supported devices, Etch can help shape what you capture into a clean card. It is entirely optional, it runs on your device, and it only ever works on the text you enter. Nothing is sent away to do it. Made to travel. The interface is in English and French, and you can create cards in many supported languages, so your notes stay in whatever language you think in. Yours, and private. Your cards sync across your own devices with iCloud, and you can export a full backup any time. Etch collects no data about you.

About

Nebulearn

Nebulearn is the most time-saving spaced repetition platform. It is seamlessly collaborative, AI native, and gamified. By using Nebulearn, you will spend less time making cards and reviewing what you already know, and more time on the stuff you need to review. Here's how. Frictionless card creation Paste notes, upload a PDF, snap a photo, or record audio and turn it into a deck. Write cards yourself when you want control, with AI autofill for explanations. Generate flashcards or multiple-choice quizzes from your own material instead of typing every card by hand. You stay in charge of the AI. Set difficulty, question count, and custom instructions so cards come out the way you actually study - cloze, definitions, exam-style questions, whatever you need. Smart studying, not extra studying Every card gets scheduled with real spaced repetition, including multiple choice. FSRS is the default: it brings a card back right before you'd forget it, so you don't waste reviews on what you already know. Switch to SM-2 or Leitner, or tune the algorithm. Everything in one place Folders, tags, search, sharing, stats, streaks, and Ask AI live while studying in the same app. There's no need to jump between a generator, a deck manager, and a review tool. Study on your phone, then pick up the same library on the web, with no manual syncing needed. What you get - AI flashcards and quizzes from notes, PDFs, images, and audio - Custom AI profiles and generation instructions - FSRS, SM-2, and Leitner spaced repetition - Image occlusion and photos on cards - Unparalleled question stats and metrics - Mastery stats, consistency, and learning pace - Seamless sharing and collaboration and public decks - Streaks, ELO, and achievements Nebulearn is free to start.
