Hey PH 👋 I built TikTok Viral Score because every "TikTok analytics" tool I found either needed a login/paid tier just to see a basic score, or was just an LLM guessing based on your description. This one fetches your video's real public data (stats, caption, hashtags, and even the auto-generated subtitle track) and scores it with a deterministic rule-based engine — five categories, instant, zero API key required. The part I found most interesting to build: a video's real reach tier (Nano→Mega, based on actual likes/plays) sets a floor for every other category. A video with hundreds of thousands of real likes shouldn't get scored near-zero just because its caption skips a copywriting rule — proven performance is treated as evidence the hook already worked. Bring your own AI key (Claude/OpenAI/Gemini/Groq/Ollama) for genuinely tailored feedback on that one video — grounded in the real fetched data, explicitly told not to penalize low view counts. It's fully open source: https://github.com/NaiaLorente/G... Would love feedback, especially on the scoring logic — happy to answer anything!
