Penbeam vs OBS Studio — which is better for recording lectures? (2026)

An honest comparison by the Penbeam team · Updated June 2026

Note: Penbeam is our own product — we try to keep this objective.

In short

If you need free live streaming, multi-scene switching and full control, pick OBS — it's powerful and open-source, but the learning curve is steep and it only records: no editing, no subtitles. If you're a teacher who just wants to annotate while you talk, get auto subtitles, and one-click remove filler words, Penbeam is simpler: recording and editing in one app, ready out of the box.

Choose Penbeam if…

You’re a teacher who wants to explain a lesson clearly

OBS is built for streamers — recording a lecture means configuring scenes, sources and plugins just to annotate. Penbeam is built around teaching, from the pen/zoom/webcam while recording to subtitles/editing afterward. No learning curve.

You need to edit and caption after recording

OBS only records — you’re left with a raw file to import into a separate editor, then find another tool for captions. Penbeam goes straight to its editor: auto subtitles, one-click removal of silences and "um/uh", export and share.

You want simple, not fiddly

OBS is powerful but full of settings — daunting the first time. Penbeam: click "New recording" and go — countdown, annotate, stop, export.

Choose OBS Studio if…

You need live streaming

OBS’s core strength is streaming and real-time scene switching to Twitch / YouTube. Penbeam doesn’t do this — OBS is the standard answer.

You need complex multi-source mixing

Multiple cameras, green-screen keying, complex transitions — OBS’s source and filter system is powerful and free. Penbeam focuses on solo teaching and doesn’t cover these.
