We measure time to first audio, check pronunciation of names, numbers and acronyms, judge naturalness blind, listen for drift across a long passage, and price the whole script. This test hasn't run yet, so Task success is pending and the grades here come from the categories assessed from public evidence.\n\n## Indexed, not reviewed (4)\n\nSorted into this category from public catalogues, with facts and our own checks but no score, grade or rank (https://www.anchorterminal.com/indexed/index.md).\n\n| Listing | Kind | What it does | Why it's here |\n| --- | --- | --- | --- |\n| [APICK](https://www.anchorterminal.com/tools/apick-all.md) | MCP server | APICK Korean data, simple-auth lookups, OCR, search, conversion, image, video and TTS | vendor's own |\n| [BananaBanana Image, Video \u0026 Speech Generation](https://www.anchorterminal.com/tools/bananabanana-image-video.md) | MCP server | Images, video \u0026 speech: Nano Banana, GPT Image, Veo, Omni, Wan, Grok, Gemini TTS.
