What is Quelta?
Quelta does two things with short vertical video ads. First, it checks how well a video sells on a given platform, in a given country and for a given audience age. The preliminary check is free; the full check shows every mistake with a timecode and how to fix it. Second, in one click it rebuilds the video into a version that sells and makes versions for other markets and languages. The fix and the generation are available in private access.
What is free and what is paid?
The preliminary check is free: up to 5 videos a day, no sign-up. It gives a score range, a checklist of 30+ metrics and a review of the first 3 seconds. The full check gives the exact score, every mistake with a timecode and how to fix it. Sign in with Google and your first full check is free; after that, full checks come in packs, from 10 for $19. To count the daily limit we use one functional cookie; signing in adds a session cookie.
What does the one-click fix do?
Based on the review, Quelta rebuilds the video: a hook in the first seconds, subtitles, tighter pacing, balanced sound, a clear offer and a call to action. You get a new video, not a list of tips. The before and after example on this page was made this way: from 22 to 94.
Is localization just a translation?
No. Besides the language and the subtitles, Quelta adapts what the ad leads with to local buyers: in one market it is the price, in another a discount or installments, in a third quality and free returns. The delivery, the pace and the text on screen change too.
How do I get private access?
Leave your email in the form on this page. We open access to brands and agencies one by one and get in touch to discuss your products, markets and volumes.
Which videos can I check?
Any vertical video ad up to 100 MB and 3 minutes long: TikTok, Instagram Reels, YouTube Shorts, X, Snapchat. Upload a file or paste a link to a public post.
How long does it take?
Usually 1–3 minutes. You can close the tab: the report opens at its link for 7 days.
What happens to my video?
The video and the report are kept for 7 days and then deleted automatically. We do not sell videos, do not share them except with the processors needed for the analysis and do not use them to train models. Details are in the Privacy Policy.
How is the score calculated?
The score is built from six categories: hook, story, offer, delivery, picture and sound. Some checks are measured precisely (loudness, cuts, subtitles), others are assessed by AI models. Each mistake shows whether it is a platform rule, a proven practice or the model’s opinion, and how sure we are.
Does a high score guarantee results?
No. The review is a recommendation: it finds typical mistakes that cost views and sales. The result also depends on the product, the offer, the audience and the ad settings.
In which languages does it work?
The site and the report are available in English, French, Spanish, German, Kazakh and Russian. The video itself can be in any common language.
