An AI agent that watches your videos
and tells you exactly why they win or lose.

Retensis is an Agentic AI video analysis platform built for short-form content creators. It scores your TikTok, YouTube Shorts, and Instagram Reels across five dimensions - Hook, Pacing, Audio, Visual, and Engagement - predicts second-by-second viewer retention, pinpoints exact drop-off moments, and gives you specific actions to improve. It also includes a full suite of AI content strategy tools, organized into four studios - Research, Create, Performance, and Agency - to help you plan, write, optimize, measure, and collaborate on every video.

You upload a video file or paste a YouTube URL. Our AI agent watches every frame, every second, listens to every word, and analyzes your content against patterns from high-performing short-form videos. Within 90 seconds you get a full report: five category scores, an overall grade, a predicted retention curve with timestamps for every drop-off, and specific rewritten hooks and captions. Pro users also get emotional pacing charts, audio-visual sync analysis, and voice delivery coaching.

Retensis supports TikTok, YouTube Shorts, and Instagram Reels. You can upload video files in MP4, MOV, or WebM format, or paste any public YouTube URL to analyze without uploading. Each analysis includes platform-specific compliance checks and optimization tips tailored to the platform you are creating for.

Yes. The free plan gives you 2 video analyses per month with no credit card required.

Most analyses complete in under 90 seconds. You upload your video or paste a YouTube URL, and our AI agent processes everything - scoring, retention prediction, drop-off detection, and rewrite generation - while you wait. Longer videos may take slightly more time, but the process is fully automated with no manual steps required.

Yes. Paste any public YouTube URL - including Shorts, regular uploads, and Reels reposts - and Retensis analyzes it directly. No download or re-upload needed. This works for your own videos and for studying what is working for other creators. The analysis is identical to what you get when uploading a file.

The Pro plan includes a full suite of AI content strategy tools, organized into four studios. Research: Radar surfaces breakout videos in your niche, Creator Research breaks down other creators' strategies, Trend Finder surfaces trends that fit your style, Topic Opportunities spots under-covered topics, Watchlist tracks competitors over time, and Audience Questions mines what your viewers keep asking. Create: Viral Planner generates scene-by-scene blueprints, Hook Writer creates ready-to-use hooks, Script Coach gives AI feedback and rewrites, and Title Lab, Thumbnail Lab, and Version Lab test and compare variations. Performance: Retention Lab scores an idea, script, or rough cut before you publish, Before vs After tracks the lift between versions, and Experiments prove what actually works for your channel. Agency: shared Team workspaces, a Command Center for client oversight, and Integrations for Slack, Discord, and webhooks. Creative DNA underpins them all by finding your winning content patterns, Weekly Missions tell you what to make next, and every tool uses your analysis history to personalize its output.

Yes, and you do not need to be a developer. Retensis connects to Claude and ChatGPT through MCP, so you can use it right inside your chat. Connect your assistant in a few clicks, then ask in plain language, for example "find trending topics in my niche," "score this title," or "break down this competitor's video." Your assistant runs the matching Retensis tool and replies with the result in the conversation. There are 14 tools covering research, content creation, and video analysis, all with secure, scoped access you can revoke at any time. It is included with the Pro plan, and you can find step-by-step setup in the MCP documentation.

Yes. Your video is stored securely so you can review it alongside your analysis. It is never shared with third parties, used to train AI models, or made visible to other users. We keep it until you delete it or close your account, and you can delete any video, or your entire account, at any time from your dashboard, which removes the file from our storage.
