The first 2 seconds
What your opening shows before the first swipe.
For Reels, TikTok and Shorts
Know what to fix before you post.
Signal watches your reel second by second, the way your viewers do, and tells you what to fix first.

Example review
What to fix first
Example reels made for this page. The review is Signal's real output.
How it works
A review takes about as long as your reel.
Upload your reel
Before you post it. MP4, MOV or WebM, up to 3 minutes.
Signal watches every second
The picture, the text on screen and every word that's said.
Fix what matters first
Each fix points to its second. Tap it and the video jumps there.
What Signal checks
What Signal checks, second by second.
Each check follows a published guide. The examples come from the reel you picked above.
Text the app covers
Each app covers part of your video with its caption and buttons. Signal flags text underneath.
Text too fast to read
Signal reads along at subtitle speed and flags lines that leave too soon.
What's said
When your first sentence ends, and how much of it people get with the sound off.

Account audit
Then it learns what works for your account.
Upload your recent reels with their numbers, or connect Instagram (read-only). Signal shows what your best reels have that your weakest don't.
On reels already posted, Signal's best bets beat its worst bets 2 times out of 3.*
*Backtest on 3 Instagram accounts and about 250 reels that were already posted, September 2026. Signal scored each reel as if it were new, using only that account's earlier reels, and compared its top and bottom picks on watch time and views. Results vary by account. Next: the same test on new reels, scored before they're posted.

FAQ
Questions people ask first.
Is Signal free?
Yes, while it's in beta. At launch there's a free plan with 3 reels a month, and paid plans from $19 a month.
When do I get access?
Signal is in private beta. Leave your email below and we'll send your access as spots open.
Do I need to connect my account?
No. Upload a video and you get the full review. Connecting Instagram (read-only) adds your numbers: how long people watch each reel, how many skip it in the first 3 seconds, and what your best reels have in common. The Pro trial is one per Instagram account.
What happens to my videos?
Signal uses them to make your review. You can delete them from your account whenever you want.
Which apps and languages does it cover?
Instagram Reels, TikTok and YouTube Shorts: vertical video up to 3 minutes, in English or Spanish. Horizontal and square videos get the same review, without the app guides.
How is this different from a virality score?
A score gives you a number. Signal shows you what happens at each second, why it matters and the rule behind it, with its source, so you know exactly what to change.
Who's behind Signal?
Pixories, an animation and video studio that makes explainer and social videos for brands. Signal is the checklist our editors use, turned into a product. The studio uses Signal like any other customer and can't see your account.
Will you contact my clients or offer them edits?
Never. We don't contact your clients, and we don't use your videos, reports or client names to sell anything. Your account and its data stay yours.
