Transcription for students

Record a lecture in the browser or upload a recording, and get a transcript you can search, quote and study from. Interviews for your thesis come out with every speaker told apart.

How SonaFact helps

Lectures you can search

Search all your recordings at once, or ask a question about them and get an answer linked to the moment it was said. Each question uses one AI job.

Interviews for your thesis

Speakers are separated automatically; rename them to participant codes once. Export to DOCX, or a file ready for NVivo, MAXQDA or ATLAS.ti, on every plan.

Record straight in the browser

Press Record, see the time and the sound level, pause and stop. The sound reaches SonaFact in parts as you speak, so if the page closes, what was recorded is kept.

Straight into NVivo, MAXQDA or ATLAS.ti

Export a file laid out the way your analysis software reads transcripts: the speaker at the start of every utterance and a timestamp that links it to the recording. Clean verbatim leaves out “um” and “uh” when you want it to. On every plan.

Good to know

Ask before you record a lecture or a conversation. A machine transcript is a draft: check the underlined words and every passage you quote before you hand anything in.

Which plan

The free plan takes 3 recordings a day, up to 30 minutes each, and writes summaries. A full lecture is often longer: Starter takes files up to 3 hours and 20 hours a month. On a student budget? Write to support@sonafact.com — we look at education requests case by case.
