Bookmarks before transcripts

AI Lecture Recorder can transcribe a whole lecture. We still made a single tap to mark a moment the most important button in the app.

  2. During: one tap beats a note
  3. After: review, not replay
  4. Where transcription fits

When we started AI Lecture Recorder, the obvious headline feature was transcription: record an hour, get an hour of text. Students told us they rarely read a full transcript. What they wanted was to find the five minutes that mattered. So we organised the product around three moments in a student's day.

BEFORE

Start recording fast

Open, tap record, put the phone on the desk. No setup screen in the way.

DURING

Mark what matters

One tap to bookmark the moment the lecturer says "this will be on the exam".

AFTER

Find it again

Jump straight to bookmarks, and transcribe only when text actually helps.

Before: getting out of the way

Lectures start whether you are ready or not. The app opens straight to a record button, and recording works fully offline. Nothing about capture depends on a network or an account.

During: one tap beats a note

The biggest button on the recording screen, after stop, is bookmark. One tap marks the current moment. A label can be added later, but does not have to be. Marking something takes less effort than writing it down, so people actually do it.

The most advanced feature is not always the most useful one. Sometimes it is a single button that fits the moment.

After: review, not replay

Reviewing a lecture is different from listening to music. You skip, rewind a few seconds, slow down a dense part, speed through a tangent.

  1. RecordPhone on the desk, screen off
  2. Tap to bookmarkMark the moment, label it later
  3. Jump backPlayback starts just before the mark
  4. TranscribeOptional, when text helps
The study loop. Bookmarks do the finding; transcription is there when you want words.
  • Playback starts slightly before each bookmark so you hear the lead-in.
  • Skip buttons are sized for the short jumps people make most.
  • Speed control is one tap, not buried in a menu.

Where transcription fits

Transcription is still there, powered by Groq, for when text genuinely helps: searching for a term, copying a definition into notes, or reviewing in a quiet library without headphones.

Optional on purpose

Transcription is a choice per recording, not a default. People decide when audio is sent for processing, and recording never depends on it.

    AI can design an app now. Are designers redundant?

    AI makes the first draft of a screen cheap. That shifts design work to what matters most: understanding users and choosing what is right for them.

    AI in software development: turn change into an advantage

    AI does not replace technical thinking. With the right process, it frees teams to focus on the decisions that make products better.

    Adding AI to an app without a surprise bill

    Most of the cost of an AI feature is decided before the first request. Model routing, caching, context size and hard limits, in order of impact.
