You attend six sessions at a conference. By the evening, how much do you remember? Most researchers leave with a few photos of slides, scattered notes and a vague feeling that someone said something important about a method they want to try. This guide covers practical ways to capture talks, lectures and meetings so you can find the details again, and where AI helps and where it does not.
Short answer: first check that you are allowed to record. Then record the audio, let a transcription tool turn it into text, and ask questions of the transcript instead of rereading it. The quality of your audio decides almost everything.
Step 1: Check that you are allowed to record
This comes before any tool. Rules about recording conversations differ by country, and many conferences do not allow audio or video recording of sessions, especially when unpublished data is presented. Before you record:
- Read the conference's recording policy, usually in the program or on the registration page.
- If a session is private or has unpublished results, ask the speaker for permission, or take written notes instead.
- For meetings (Zoom, Teams, lab meetings), tell everyone that you are recording and why.
If permission is unclear, do not record. Written notes are always allowed.
Four ways to capture a talk
1. Handwritten or typed notes
Notes force you to decide what matters, which helps understanding. Their weakness is that you miss things while you write, and you cannot search a notebook page by a phrase you half remember.
2. A voice memo on your phone
Simple and free. The audio is complete, but an hour of audio is hard to use. Nobody replays 60 minutes to find one number.
3. A meeting bot that joins your call
Tools like Otter, Fireflies and the built-in assistants in Zoom and Teams join a video call and write notes. They work well for online meetings you host. They are not made for a lecture hall, and a bot joining someone else's meeting needs the host's approval.
4. Record in the browser, then transcribe and ask questions
ProfAgent Recordings works this way. You open ProfAgent in your phone or laptop browser, tap record, and it saves the audio, writes a transcript, summarizes it and lets you ask questions about what was said. There is nothing to install. It is one tool among several, and the same approach works with other transcription services too.
How ProfAgent Recordings works
- Record: choose Microphone for a room (conference session, lecture) or Online meeting for Zoom, Teams, Meet or a video tab on your laptop. For online meetings the browser asks which tab to share, and you tick "share audio".
- Live transcript (optional): you can watch a rough transcript appear while you record. The final transcript is produced when you stop.
- Summary: a summary with key points, decisions and questions worth following up, and an automatic title if you did not type one.
- Ask questions: type or speak a question, such as "what did the speaker say about sample size?", and hear the answer read aloud if you like. Answers come from the transcript.
- Listen again: the saved audio is kept so you can check the exact words. It is deleted when you delete the recording.
Tips for better recordings
- Sit near the front or place your phone close to the speaker. Distance is the main cause of poor transcripts.
- Keep the screen on. A locked phone or another app in front can pause recording in a mobile browser. Plug the phone in for long sessions.
- Test for one minute before the first session and read the result.
- Use headphones if you are asking questions by voice later, so the answer is not picked up by the microphone.
- Add a name you will recognize or leave the title empty and let the tool name it.
Limits you should know
- Automatic transcripts contain mistakes, especially with names, formulas, accents and background noise. Check anything you plan to cite against the audio or the slides.
- Speakers are not labelled, so a discussion with several people can be hard to follow.
- A summary is a starting point. It can miss nuance, so read the transcript for anything important.
- Free accounts include a small trial of Recordings, and paid plans have a daily recording limit.
An evening routine that works
After the day, open your recordings and read each summary first. Ask two or three questions per session: what was the main claim, what data supported it, and what should I read or try next. Copy the answers into your notes with the speaker's name and session title. Ten minutes per session beats an hour of rewatching.

Is it legal to record a conference talk?
It depends on the country, the conference rules and whether the speaker agrees. Many conferences forbid recording, and unpublished data is often protected. Always check the policy and ask for permission. If in doubt, take written notes.
Can I record a Zoom meeting without installing anything?
Yes, in a computer browser you can record the meeting tab's audio plus your microphone with ProfAgent Recordings, using the Online meeting option. Tell the other participants that you are recording.
Does recording work on a phone?
Yes, by opening ProfAgent in your phone's browser. Keep the screen on and the page in front, because locking the phone or switching apps can pause the recording.
How accurate are automatic transcripts?
Accuracy is good for clear speech in a quiet room and worse with distance, noise, accents and technical terms. Treat the transcript as a searchable draft and check important details against the audio.
Can I ask questions about a recording?
Yes. In ProfAgent you can type or speak a question about a saved recording and get an answer based on its transcript, which is faster than replaying the audio.
