Recordings from any call
Zoom, Google Meet and Microsoft Teams save recordings as MP4, and AutoCap captions them as they are.
A Riverside alternative for calls you've already recorded.
Keep recording where you and your guests already meet. AutoCap turns the recording into captioned clips afterwards.
No credit card · 2 free minutes every month · MP4, SRT and VTT export
Riverside is a studio for recording conversations: each guest is recorded on their own device in high quality, on a separate track, with text-based editing, AI-picked clips, captions and live streaming around it.
When recording quality is the priority, that setup earns its place. Plenty of good conversations happen somewhere else, though: on a Zoom call with a client, in a team's weekly Google Meet, in a webinar run on Microsoft Teams.
AutoCap starts from those recordings. Upload the MP4 the call already saved, caption it word by word, and post the moment that mattered.
Captions for the recordings you already have.
Nothing new for your guests
Guests keep the call tool they already know; there's no studio link to send and nothing for them to set up.
Captions placed around faces
Move the captions anywhere in the frame, so they sit under a speaker-view face or between the tiles of a gallery view.
Styles that survive compression
Outlined and boxed styles stay legible over the soft, compressed picture a call recording usually has.
From call recording to captioned clip in four steps.
- 01
Find the moment
Note the timestamp of the answer worth sharing while the call is fresh, then trim it from the recording.
- 02
Upload the MP4
Add the trimmed recording; AutoCap transcribes the speech and times each word.
- 03
Correct and place
Fix names and jargon, then position the captions clear of faces and the call's own labels.
- 04
Crop and export
Choose 9:16 or 1:1 if the clip is going to a feed, and render the MP4.
When Riverside is the better fit
If the recording itself is the product — a show where every guest should sound and look their best, on separate tracks you can fix one by one — a dedicated recording studio is the right tool, and AutoCap doesn't record anything.
The same goes for live streaming to several platforms at once. AutoCap begins after the recording ends.
A cleaner clip from a call recording
Transcription is only as good as the audio, and calls are where audio goes wrong. Ask guests to wear headphones so their speakers don't echo into the microphone, and record in speaker view if you plan to crop to vertical.
Trim each clip to one complete answer, and check the first line twice: a call recording rarely starts at a clean sentence, so the opening words are where a misheard fragment sneaks in.
Good to know.
Can AutoCap caption a Zoom recording?
Yes. Zoom saves recordings as MP4, which you can upload as they are; clips can run up to 60 seconds on the free plan and 5 minutes on paid plans.
Can AutoCap record calls or interviews?
No. It captions recordings you already have, made in whichever app or camera you use.
Do my guests need to install anything?
No. AutoCap is used only by whoever makes the clips, after the call is over.
Is there a free Riverside alternative for captions?
AutoCap's free plan includes 2 minutes of transcription each month on clips of up to 60 seconds, without a card, and adds a small watermark to exports.
Is AutoCap affiliated with Riverside?
No. Riverside belongs to a different company and is named here only for comparison.

The free plan needs no card. Upload a clip, check the captions yourself, and only upgrade when you want the watermark gone.
