Paste a public TikTok link and get an instant, deterministic breakdown of your hook, hashtags, timing, and real reach — no AI model needed for the free score. Add your own API key (Claude/OpenAI/Gemini/Groq/Ollama) for tailored written feedback on that exact video: what's working, what to fix, and an alternate caption to test. Also includes a Spotify-Wrapped-style recap of your own posting habits.
