AI analyzer for viral scores, captions and hashtags
Our AI tool for creators and social media managers: upload a photo to assess its viral potential, improve captions and suggest hashtags for Instagram and TikTok in multiple languages.
The challenge.
Creators often cannot tell whether a post has viral potential or which captions and hashtags could expand its reach. Manual testing takes time, while external agencies can be expensive and difficult to scale.
What we built.
A progressive web app with AI-powered image analysis. Upload a photo and get a viral-potential score, three improved caption options and curated hashtag sets in seconds. It supports German, English and Russian, can be installed as an app, offers Google sign-in and includes three free analyses.
