Captions written from your video
Most caption generators only see the text you type. UploadFlow looks at key frames of your video and transcribes what is said, so the title and captions describe what really happens in the clip.
What the AI looks at
Key frames
Several frames across your clip show the scene, the action and any on-screen text.
Spoken audio
What you say in the video is transcribed and taken into account.
Your context and voice
Add optional context, pick a tone and a brand voice, and the AI writes for each platform you picked.
What you get per video
Title suggestions
Several YouTube titles to choose from, or write your own.
Platform captions
Separate captions for TikTok, Instagram, Facebook and LinkedIn, plus a YouTube description and tags.
Hook and virality scores
A score for the first seconds of your video with a concrete tip to improve it.
Captions that sound like you
Describe how a brand talks once, in any language, and link it to its accounts. Every caption for those accounts follows that voice. Agencies can set a different voice per client.
AI caption questions
