Upload an image → get SEO alt text (≤125 chars), an SEO title, 2 caption options & keywords. On-device image analysis by default — no key needed.
Keys are kept in this page's memory only — never stored, never sent anywhere except directly to the AI API you chose. Get a free Gemini key at aistudio.google.com (no card) or a free HuggingFace token at huggingface.co → Settings → Access Tokens (read-only). If a key call fails, the tool falls back to the on-device estimate with a clear notice.
