Signature look
Instrument Phrase
A short OnnOff intro in Instrument Phrase - who we are, what Capten is, and who it’s for. Hero word lands, support follows, then the next line.

How it works
Upload once. Caption like an editor.
01
Drop a Reel
Upload MP4 or MOV. Capten pulls audio and listens for Hinglish the way you speak it - not textbook Hindi.
02
Shape every word
Fix timing, pick a look like Instrument Phrase, nudge the hero word, save it as your brand kit.
03
Burn & ship
Export an MP4 with captions baked in - or on Pro+, send the Reel on WhatsApp and get it back captioned.
Editor
Built for finishing, not fighting the UI.
Timeline on the left. Preview in the middle. Style and kits on the right. Capten feels closer to a cut tool than a subtitle form.
Word-level timeline
Drag, trim, and retime captions the same way you scrub a Reel - not a subtitle spreadsheet.
What you see is what burns
Preview uses the same styling path as export, so Instrument Phrase doesn’t “flatten” on download.
Brand kits that stick
Save once. Reuse across videos and clients - fonts, lockup, colors, motion included.
Shoot on your phone. Caption in chat.
On Pro and Agency, link your WhatsApp number once in the dashboard, then forward Reels to Capten's bot. Your default brand kit and language apply automatically - the captioned MP4 comes back in the same thread. Tweak words later in the web editor if you need to.
