Subtightl - Auto Captions

About Subtightl - Auto Captions

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.
