The brain behind every video

The only video generator
that knows why videos win.

Other tools render and hope. Retentionr started as a retention analytics engine — so every script is scored, every hook is tested, and every published video feeds data back into the next one.

Publish and learn

One click — or Autopilot — publishes to YouTube. Live stats flow back in, so every next video is smarter than the last.

Most channels don't fail
from ideas. They fail from blind spots.

Creators don't know what loses attention.

They don't know why retention drops.

They don't know what their audience actually responds to.

Retentionr identifies those blind spots.

Creators using Retentionr

Your audience has patterns.
Retentionr learns them.

Retentionr studies your past videos to understand what drives retention and engagement on your channel — then adapts its analysis to you.

Platform Intelligence

Retentionr gets smarter
with every creator.

When a video blows up on any channel using Retentionr, we learn why. Those patterns feed back into every analysis — so the more creators use the platform, the sharper it gets for everyone.

Breakout Detection

When a video hits 3x+ a channel's average, Retentionr automatically flags it and extracts what made it work.

Niche-Specific Learning

Patterns are tagged by niche. Cooking insights stay with cooking creators. Streamer clip patterns stay with clip channels.

Evidence-Backed Advice

Your analysis isn't based on theory alone. It's informed by what's actually working for real creators, right now.

Trusted by creators who
care about retention

My retention jumped from 42% to 68% in two weeks. Retentionr showed me my hooks were burying the lead every single time.

Alex Rivera
@AlexCreates
+62% retention

I used to guess what was wrong with my videos. Now I know exactly where viewers drop off and why. Game changer for my workflow.

Priya Sharma

Channel DNA is insane. It figured out that my audience responds best to tutorials under 8 minutes with a question-style hook.

Questions, answered.

Faceless YouTube Shorts and full-length 16:9 videos. Pick a template — Reddit stories, fake text dramas, Fruit Drama / Fruit Love Island (real AI video), psychology facts, true crime teasers, history in 60s, finance explainers, and more — or describe your own series. The AI writes the script, generates visuals, records a lifelike voiceover, adds word-synced animated captions and music, and renders a finished MP4.

Yes. Connect your channel once, and every finished video can be published with one click — title and description pre-filled by the AI. On the Studio plan, Autopilot generates and publishes videos on a schedule you set, fully hands-off.

Retentionr is a retention analytics engine first. Every script is retention-scored before rendering, and after publishing, live YouTube stats flow back in — so the platform tells you which formats are winning on your channel and helps you make more of them. Other tools render and hope; Retentionr closes the loop.

No. You never touch an editor, a microphone, or a camera. Type an idea (or let the AI suggest one), pick your look, and get a finished video in about 5 minutes.

On the Studio plan, you define a custom template — your niche, art style, voice, captions, and music. Autopilot then generates a fresh video from it daily, every 3 days, or weekly, and can auto-publish straight to your channel. Your faceless channel keeps posting even while you sleep.

The free Hobby plan includes 3 shorts per month so you can try everything. Creator includes 50 shorts (50% off your first month), Pro includes 80 shorts plus 4 long-form videos (also 50% off first month), and Studio includes 100 shorts plus 8 long-form videos and 30 studio credits/month for Sora video and cinematic motion, plus Autopilot and custom templates.

Yes — a real one, no credit card required. You can generate a video, run script and video analyses, and see the whole workflow before paying anything.

No. Every image is generated fresh for your script in your chosen art style — with style consistency enforced across every frame. Combined with 15 art styles, 6 caption presets, 6 voices, and custom music uploads, no two channels look alike.

Your channel doesn't
need you anymore.

Videos that write, render, score, publish, and improve themselves. You just pick the direction.
