FAQ
Is the caption generator really free?
Yes — 5 minutes of AI captions every month with no credit card. If you need more, Pro is $5/mo for 100 minutes.
Do I need to install anything?
No. ReelCaption runs entirely in your browser. Drop in a clip, caption it, and export.
Is there a watermark on free exports?
No. Your captioned MP4 has no watermark, even on the free tier.
Is my video uploaded to a server?
No. Your video is processed in your browser and never leaves your device. Only the extracted audio is sent for transcription, and it is not stored afterwards.

Your next clip is one drop away.

Just $5 a month, about the price of one coffee, and you can cancel whenever you want. Open the studio, drop your video, and post a captioned MP4 in under a minute.
