About this app
85% of social videos are watched on mute. Without captions, you're losing views before the first word is spoken. Subtightl fixes that in seconds.
Pick a video. Choose your language. Get accurate, timed subtitles — burned right into the video, ready to post. No manual typing. No expensive software. No learning curve.
What you get
More views, more reach
Captions keep viewers watching longer. Subtitles make your content accessible to muted scrollers, non-native speakers, and hearing-impaired audiences — all at once.
AI transcription that actually works
State-of-the-art speech recognition — accurate across accents, noise, and fast speech. Supports Russian, English, Spanish, French, German, Italian, Portuguese, Japanese, Korean, and Chinese.
Subtitles that look good
Multiple font styles and highlight colors so you can match the look to your content — bold, clean, or cinematic. Live word-by-word preview so you see exactly what you're getting before you export.
Export your way
Burn subtitles directly into the video for Instagram, TikTok, or YouTube Shorts. One tap to share or save.
Pricing that makes sense
Try it free
Every new account gets a starter allowance so you can run a real job before you spend anything.
Pay for what you need
Top up with credits and use them at your own pace — no forced bundles.
Go unlimited if you post often
One subscription removes the limits so you can keep creating without watching the clock.
Stay in control
Credits work without a subscription; subscribe only if it fits how you work.
No ads — ever
We'd rather charge fairly than interrupt your workflow.
How it works
1. Open Subtightl and pick your language
2. Select a video from your device
3. AI transcribes the audio in seconds
4. Preview subtitles with live word highlighting
5. Style, export, and post
Stop losing views to silence. Add captions and let your content speak — even on mute.
