What Shortimize does
Shortimize is a short-form video analytics platform for tracking performance across TikTok, Instagram Reels, YouTube Shorts, Facebook, Snapchat, and X - in one synced dashboard. Its strength is breadth and speed: unlimited account tracking (including accounts you do not own), near-real-time data refresh, viral-content discovery, competitor and influencer monitoring, and integrations that push data into Slack or Discord. It is built for creators, agencies, and teams that need to watch many accounts and spot trends fast.
What it does not do is watch the video itself. Shortimize reports the numbers around a video - views, engagement, cadence - but it cannot tell you that your hook at second 2 is where 40% of viewers left.
Shortimize is the right tool when you are monitoring lots of accounts or competitors and want fast, cross-platform metrics in one place.
What Reelyze does
Reelyze is an AI short-form video analyzer. You paste a single public Reel, TikTok, or Short URL - no account connection - and it watches the footage frame by frame the way an editor would: scoring the hook, mapping the retention curve, reading on-screen text and pacing, and pinpointing the exact second viewers left. Then it gives a clear verdict and specific changes to make. It also includes free no-sign-up tools (transcript, downloader, MP3 extractor), a Content Studio that drafts hooks and scripts, and Reelyze Chat for strategy.
Reelyze is the right tool when you want to understand and fix why a specific short video worked or flopped - yours or a competitor's.
The core difference: breadth vs depth
Shortimize answers how are my videos and my competitors' doing, across a whole portfolio. Reelyze answers why did this one video underperform, and what do I change, on a single clip. Shortimize is a dashboard of metrics; Reelyze is a frame-by-frame diagnosis with prescriptive fixes. They are complementary - track the field with one, fix the play with the other.

Which should you use?
If you run or manage many accounts and need to monitor performance and competitors at scale, Shortimize is built for that breadth. If you want to know why a specific video underperformed and how to fix it, that is Reelyze - it watches the footage and tells you what to change, which a metrics dashboard cannot. Many creators pair them: Shortimize to spot which videos over- or under-performed, Reelyze to diagnose the ones that matter and improve the next post.
