Frequently asked questions

Will this get me more views?

Retti shows you where viewers leave and what to change. When people watch for longer, YouTube tends to recommend the video more, and that is where more views, and more ad revenue, come from. It can’t promise a number: the change comes from making the fixes on your next upload.

What do I need to start?

A YouTube video link and a screenshot of that video’s audience retention graph from YouTube Studio (Analytics, then Engagement). Your first full review is free.

Can I review a video before I post it?

Yes. Upload your cut to Edit Review and Retti leaves timestamped notes on the frames: where viewers would leave, and what to change before anyone watches.

How is Retti different from vidIQ or TubeBuddy?

Those tools work on titles, tags, thumbnails and search. Retti works on what happens after the click: it reads your video against its real retention graph, finds the moments viewers leave, and tells you what to change so they keep watching.

What kind of tool is Retti?

An AI YouTube retention analysis tool for long-form videos. It reads a published video against its real audience retention graph from YouTube Studio, shows the moments viewers left and why, and tells you what to change. It also reviews your edit before upload, your script before filming, and your hook.

Does Retti predict retention, or read the real thing?

For a published video it reads the real thing: the retention graph YouTube Studio recorded for that video, matched to what was being said and how the section was built at each drop. Before upload there is no graph yet, so Edit Review, Script Review and Hook Review read the cut or the script itself. Once the video is live, Video Review shows where viewers really left.

Does Retti work for Shorts?

No. Retti is built for long-form YouTube videos, 8 minutes and up, where holding viewers through the middle is what decides watch time.

What comes with Pro?

Video Review, Edit Review, Hook Review, Script Writer, Video Planner, the Retention Dashboard and Retti AI, all on one monthly credit balance. Pro also works inside Claude, ChatGPT and the Retti Chrome extension.

Does Retti learn from my videos?

Retti learns which patterns hold viewers from the videos reviewed on it, so its reads get sharper over time. Your own data stays private.

Can I cancel anytime?

Yes. Upgrade, downgrade or cancel whenever you like. Changes take effect at the end of your billing period, with no long-term contract.
