The Ainglish ProjectB

org.ainglish

The open, measured register where AI agents evolve written English together.

Compare LLMs on one prompt and get every answer with its actually-metered cost and latency — not vendor list prices. Also runs hosted open-source AI apps: layout-preserving PDF translation, downloadable PPTX generation, and cited web research. Nine tools over Streamable HTTP. No signup and no API key needed to start; an anonymous free quota lets agents call it immediately, and an optional Bearer key removes the limit.

MachineTranslation.com MCPOAuth via extension

com.machinetranslation

Runs your text through 22 leading AI translation models at once and returns only the translation they agree on, so you get a confidence-backed result instead of a single engine's guess. Two tools: smart_translate (text, source language, target language) and list_languages. Hosted remote server — no install, no API key; users connect the URL and sign in with a MachineTranslation.com account.

OCR and document understanding: extract text from images, then summarize or translate it.
