Going viral isn't luck. It has a DNA. 

ViralDNA is built and tuned for YouTube, where hooks, retention and thumbnails decide everything. The script and hook insights transfer well to Shorts, TikTok and Reels too.

ViralDNA's evidence-based analysis engine examines the competitor video's script. The text is scored on 16 fixed sub-criteria across 4 dimensions: hook, retention, emotional impact and viral triggers, and for every sub-criterion the meaning of each score from 0 to 4 is defined in advance. The AI must justify every score with a verbatim quote from the text; the system checks each quote against the original script and automatically lowers any high score whose evidence cannot be found. The overall score is not guessed by the AI, the system calculates it from those sub-scores. Finally, the findings become a strategy brief of more than 10,000 characters that shows the evidence behind every instruction, so you can bring the competitor's strengths into your own video and outperform it where it falls short.

Script Analysis scores a competitor video's script on 16 evidence-backed sub-criteria, decodes why it gets watched and hands you a detailed, ready-to-use strategy brief to bring its strengths into your own script. Scenario Analysis goes deeper: it picks the best fit among 6 narrative engines, audits your full script scene by scene and delivers a report down to the finest detail so not a single weak spot is left in your text. In short, one decodes the competitor's success formula, the other X-rays your own script scene by scene.

Paste your script or a video transcript and the tool reads it line by line against YouTube's Community Guidelines and advertiser-friendly content guidelines. Every risky phrase is flagged with where it appears and a safer way to say it, so you can catch wording that tends to lead to limited ads (the yellow dollar icon), age restrictions or a strike before you upload. A finding that cannot be tied to a quote from your text is dropped. It works on text alone, so your script is all it needs. YouTube makes the final decision, and ViralDNA is not affiliated with YouTube.

Give it a video link, a channel or a written idea, and it generates 3 different post variants in your channel's tone, with poll and quiz options plus an image picker. Pick the variant you like, copy it and paste it straight into YouTube's community tab.

Yes, both are free to install. ViralDNA Auto Flow runs your Google Flow prompts in batches and downloads every result in order, and that part is free. Its Audio to Video mode, which turns a voice-over into scenes, is part of Pro and uses script tokens. ViralDNA Competitor Tools works on YouTube: the transcript, thumbnail and tag tools are free without signing in, and the AI analysis inside the popup is part of Pro.

Pro is $14.99 a month and you can cancel anytime. It unlocks unlimited script analyses, thumbnail analysis, the Opportunity Niches radar, Silence Remover, SRT Maker, Sync for CapCut, channel RPM estimates in the extension and 25 script tokens every month. Members who subscribed at an earlier price keep that price. Script tokens for the heavier tools (Scenario Analysis, Policy Audit, Community Posts) are also sold in one-time packs.

No. Every analysis comes as a clear roadmap in plain language. If you can paste text, you can use ViralDNA.

Absolutely. Faceless creators rely on script and thumbnail strength more than anyone, which is exactly what ViralDNA optimizes.

Yes, in three ways. Thumbnail Analyze scores a cover's strengths, weak points and click potential. Thumbnail Preview shows it on a replica of the YouTube home feed between other videos, on desktop and mobile. Viral Thumbnail Pro AI in Thumbnail Studio writes a design brief from your title and summary, generates finished thumbnails and checks that the headline text reads correctly before you see the result.

Yes. Start free with a full analysis and no credit card. Upgrade to Pro for unlimited script and thumbnail analysis whenever you're ready.

ViralDNA is an independent product, live since May 2026. You sign in with Google only and payments run through Stripe, so we never see your card details. Silence Remover, SRT Maker and Sync for CapCut process your audio and images on your own computer; nothing is uploaded. Both Chrome extensions are published on the Chrome Web Store and each has its own privacy policy, linked at the bottom of every page. Questions sent to support@viraldna.io are answered by a person.
