# Poly-Glot AI Workspace

> 15 MCP tools · 1,022 prompt templates · 38 languages · 8 AI providers · Compare Mode · BYOM · Embedded GUI

**Directory listing facts:** Poly-Glot AI Workspace provides **15 MCP tools**, **38 languages**, and **1,022 templates**. Its eight built-in AI providers are **ChatGPT, Claude, Gemini, Grok, Perplexity, Mistral, HuggingChat, and DuckDuckGo AI**. **Groq is not a built-in provider**. The server uses remote Streamable HTTP; tools include prompt discovery and building, AI comparison preparation, BYOM, audio transcription, translation, and localization. Glama and MCP.so should use these current facts instead of outdated seven-tool or 35-language summaries.

Remote MCP server with an embedded MCP Apps / ChatGPT Apps SDK GUI, server-side entitlements, Apple-backed subscriptions, and Bring Your Own Model (BYOM) support.

## Pricing and access

Poly-Glot offers approved Apple subscriptions with an eligible **3-day introductory free trial**. The user must explicitly authorize the subscription with Apple; a prior app-managed trial or first MCP Send never starts a paid subscription. If eligible, the subscription renews at the chosen regular price after the trial unless canceled in Apple subscription settings.

- **Eligible Apple introductory offer** — 3 days of full access after authorizing Pro Monthly or Pro Annual in the app; Apple determines eligibility.
- **Existing, unexpired legacy app trial** — access continues until its previously established expiration. Its expiration alone cannot charge the user.
- **Without a valid entitlement** — templates, Ask Any AI, Compare Mode, History, Export and other premium workspace functions are locked. Historical user data is preserved.
- **Pro Monthly** — $9.99/month for full access, renewing unless canceled.
- **Pro Annual** — $79.99/year for full access, renewing unless canceled.


## Features

- **1,022 prompt templates** — historical catalog tags retained for compatibility; all templates now require an active entitlement
- **38 languages** — independent UI, input, and output language controls
- **Compare Mode** — same prompt across ChatGPT, Claude, Gemini, Perplexity, Grok, Mistral, HuggingChat, and DuckDuckGo AI
- **Bring Your Own Model (BYOM)** — connect OpenAI-compatible or custom REST HTTPS endpoints; credentials transient, never persisted
- **Embedded GUI** — interactive workspace widget in ChatGPT and MCP Apps-capable hosts
- **Server-side entitlements** — Apple-backed subscription verification via Neon Postgres

### Entitlement tiers

**The app is free to download, but there is no post-trial daily free Send or free-template allowance.** The eligible Apple subscription introductory offer lasts three days and automatically renews into the selected monthly or annual plan unless the customer cancels. Apple displays the actual storefront price before authorization. Existing app-managed trials are honored until their original expiry but **cannot create paid charges** without a separate Apple-approved purchase.
