How we turn one question into the best possible answer — using every frontier AI model available. The complete decision tree from user input to synthesized output.
ChatGPT + Claude + Perplexity + Gemini + Grok + DeepSeek + Llama + GLM = €77+/mo separately. Yonoo Pro = €19.99/mo.
Users don't need to know which AI is best. Yonoo's intelligent router analyzes every question and sends it to the optimal model automatically.
When accuracy matters most: send to multiple AIs simultaneously, synthesize the best answer. Inspired by Perplexity's Model Council, included in every plan.
Starting at €5.99/mo. Study modes, quizzes, family plans for 5 users at €29.99. No AI company serves this market specifically.
From the chat interface at yonoo.ai/app. The message includes: text content, selected task type (Write, Learn, Create, etc.), active Composer Mode (Fusion, Coding, Research, etc.), conversation history, and any uploaded files.
Server validates user token, checks subscription tier (Free/Student/One/Pro/Family), and enforces usage limits. Free: 50 chats/week. Student: 100/week. Pro: unlimited. All tiers get access to all 8 AI models — we democratize access, not quality.
Before routing, we check for special composer modes that bypass standard routing:
routeAI()The heart of Yonoo. A 4-priority decision system that analyzes the question and picks the best AI:
When one AI isn't enough. Multiple models answer the same question — then the best insights are synthesized into one superior response.
Perplexity charges $40/mo for this. Yonoo includes it in every plan.
For factual queries, Yonoo first fetches real-time context from Perplexity (web search), then feeds those facts to the routed AI. This means even Claude or GPT answers are grounded in current reality — not just training data.
The selected model (or Fusion synthesis) generates the response. Each provider uses its native API format — OpenAI-compatible for most, custom SDK for Claude. Yonoo handles all the API differences transparently.
Every response arrives with full transparency: which AI answered, why it was chosen, and any web sources used. The user always knows which model they're talking to — that's the Yonoo promise.
