About Dualyne
Every AI model, one prompt away.
Dualyne is a small, independent product built by the Dualyne team. We made it because picking an AI model shouldn't take five accounts and five subscriptions: you should be able to ask a question, see how different models answer, and use the one that works for you.
What you can do
- Chat with Claude, Llama, DeepSeek and Mistral for free, with no signup, in the browser or on Telegram (@dualynebot). Pro adds GPT-5, Gemini 2.5 Pro and Claude Sonnet and Opus.
- Compare two models on the same prompt, side by side, and vote for the better answer. Votes build a public leaderboard.
- Build with one OpenAI-compatible API key for every model in the catalog.
How it works
Your message goes from Dualyne to OpenRouter, which passes it to the model's provider (Anthropic, Meta, DeepSeek, Mistral, OpenAI, Google) and streams the answer back. We don't train models and we don't sell data.
How we make money
Free chat and comparisons run on the smaller models, paid for by us within a daily budget. To keep it fair, each person gets a number of free messages a day, and on a very busy day free chat can pause until 00:00 UTC. Pro is a flat $19 for 30 days, paid in crypto, and unlocks the premium models. Developers pay model cost plus 15% through the API. That's the whole business: no ads, no selling data.
Your privacy, in short
- Chats on the website stay in your browser. We don't store the text on our servers.
- The Telegram bot remembers your last 10 messages for one hour so it can follow the conversation.
- We count visits without cookies and without storing IP addresses.
The details are in the Privacy Policy and the Terms of Service. You can check that everything is running on the status page.
