This workflow suits students reviewing a class, professionals revisiting a training session and learners working through an audio course. It handles uploaded recordings after the session, not live classroom captioning.
From a recorded class to searchable lecture text
Upload MP3, WAV or OGG audio and select the recognition language. Once processing finishes, open the result to read the transcript beside the audio. Click a timestamp when a definition or explanation needs another listen.
If a class includes questions from students, optional speaker separation can help distinguish turns. Labels such as Speaker A and Speaker B are not verified identities, and overlapping voices can still be difficult to separate.
Build notes in three passes
- Find the structure: read the transcript and identify the main topics and changes in subject.
- Condense the ideas: generate the Summary and review its overview and key points. Generate a Mind Map separately if you want a topic hierarchy.
- Make the notes yours: copy useful points into your notes, add your own examples and write questions for later review. Keep a timestamp beside definitions you may need to revisit.
Check what the audio cannot tell you
A lecture recording may contain “as you can see here” without explaining the diagram on screen. Audio transcription does not read slides, handwritten formulas or a whiteboard. Add that material yourself from the course resources.
Check names, specialist vocabulary, abbreviations and numbers by replaying the relevant segments. A clear microphone recording gives you a better starting point than distant speech mixed with classroom noise. A transcript should support your understanding of the class, rather than become an unchecked replacement for it.
Plan for the length of your lecture
Free supports 30 minutes per file and 30 transcription minutes per month, up to 200 MB per file. A longer lecture needs a plan with a suitable duration allowance: Basic supports files up to two hours and 500 MB; Pro supports up to four hours and 1 GB.
Paid plans support Word export. You can include timestamps and speaker labels in the transcript document. Recording and uploading a class should follow the permission and course rules that apply to your session.
A lecture excerpt and a study-note outline
Illustrative example written for this guide, not a customer recording or a guaranteed AI result.
LECTURE EXCERPT [02:10] Speaker A: Correlation describes how two variables move together. It does not, by itself, tell us that one caused the other. [02:24] Speaker A: A third variable can influence both. Think about temperature, ice-cream sales and swimming. STUDY NOTE — WRITTEN FROM THE EXCERPT Concept: Correlation is an association, not proof of causation. Example: Temperature can affect both ice-cream sales and swimming. Review question: What other variable could explain an observed association? Replay: 02:10–02:24. MIND MAP OUTLINE Correlation ├─ Association between variables ├─ Causation is a separate question └─ Possible third variables
Frequently asked questions
Can I turn a lecture into notes automatically?
TranscribeX.ai generates the transcript, summary and mind map. You can use those outputs to assemble study notes; custom flashcards, quizzes and Cornell-note layouts are not built-in outputs.
Can it transcribe slides or equations shown on screen?
No. This audio workflow processes spoken content, not slide images or a whiteboard. Add visual material to your notes separately.
Does it record the lecture for me?
No. Upload an existing supported audio file. It is not a live lecture recorder.
What if my lecture is longer than 30 minutes?
The Free per-file limit is 30 minutes. Basic supports up to two hours per file and Pro up to four hours, subject to the file-size and available-minute limits.
