Tap, talk, post. You had a thought worth posting. You opened your camera, recorded thirty seconds of yourself, then hit a wall. Uncaptioned video gets scrolled past. Most people give up. The ones who don't open a video editor, fight with auto-caption settings, wait for processing, fix three typos, export, and finally upload. Nine minutes later, the moment is stale. CapQuick is the fix. Open the app. Record. Captions appear. Tweak the font, color, or size if you want. Share to X. Done. That's it. No editor. No timeline. No clip-cutting. No subscription. What you get: - Quick automatic captions. - Customize font, color, emphasis color, stroke, and background per video. - Direct share to X and other social platforms. - Landscape and portrait video support. - Burned-in captions, ready for any platform. - Pre-recorded video import for captioning clips you already shot. Built for: - Tech founders and builders who post takes - Finance and crypto commentators - News and political voices - Sports takes - Educators and creators who want their face on the timeline - Anyone who wants captions for accessibility without the editing tax What's different: No subscription. CapQuick is free with a small watermark, or pay once for the watermark-free Pro version. No cloud upload. Your audio is processed on device using Apple's speech recognition. Nothing leaves your phone unless you share it. No timeline editor. We don't cut your video. We caption it. No accounts, no signups, no email required. Open the app and go. Privacy: CapQuick processes everything on your device. No analytics, no third-party tracking, no audio uploaded to a server. Your video stays on your phone unless you choose to share it. Built by Justin Hammon, an indie iOS app maker who got tired of paying $20 a month for tools that should take ten seconds. Tap, talk, post.
