How it works
From upload to published, in three steps
Upload
Drag in one video. Flow detects its resolution, duration, and checks for watermarks automatically.
Select Platforms
Pick which platforms and accounts to post to. Write once, or let Claude generate captions per platform.
Post or Schedule
Publish now or let Flow pick the best time per platform. We resize, caption, and post automatically.
Power features
Not just cross-posting.
The smartest video tool on the internet.
AI Caption Writer
Claude writes a different optimized caption for every platform — casual and hashtag-heavy for TikTok, SEO-rich for YouTube, question-based for Facebook. Edit any of them before you post.
Auto-Resize for Every Platform
Upload one video and Flow reformats it automatically: 9:16 vertical for TikTok and Reels, 16:9 for YouTube, 1:1 for Facebook, 2:3 for Pinterest. No manual cropping, ever.
Best Time to Post
Skip the guesswork. Flow schedules each platform at its own proven peak engagement window — Tuesday 7am on TikTok, Wednesday 11am on Instagram, and so on.
Bulk Upload & Schedule
Drop in up to 30 videos at once, set a caption template and destinations, and Flow spreads them across the month automatically. One session, a month of content.
Content Vault
Every video you've ever posted through Flow, in one library. One click to repost any of it — with a fresh caption — to any platform or account.
Watermark Detector
Before cross-posting, Flow checks for TikTok or Instagram watermarks and warns you if reach could suffer — so you never accidentally post a stamped repost.
TikTok watermark detected
Posting to other platforms may reduce reach. Continue anyway?
Auto-Retry Failed Posts
If a post fails, Flow retries automatically up to 3 times with exponential backoff. You're only notified if every retry fails — no babysitting required.
Automatic retry with exponential backoff — no manual work needed.
Performance Score
48 hours after posting, Flow scores every post 0–100 based on views, engagement, and shares — and crowns your best-performing platform automatically.

Creators are getting hours back every week
“I used to spend an hour every day re-uploading the same video five times. Now it's one upload and I'm done before my coffee's cold.”
Maya Chen
Full-time creator, 480K followers
“The AI captions alone are worth it — they actually sound native to each platform instead of the same copy-pasted line everywhere.”
Jordan Ruiz
Video editor & consultant
“We run 14 client accounts through Flow's Agency plan. The Vault turned three years of dead content into a second content calendar.”
