What Hiperyon is
Hiperyon is a browser extension that lets you use several AI models at once and keeps a shared memory of your context between them. You can call ChatGPT, Gemini, Mistral, and Grok without re-entering the same information each time you switch. The extension records your conversation context and carries it to the next model, so a research session or drafting task continues instead of restarting. The product states that it protects personal data, and it offers a free plan with no credit card required.
What you can do with it
- Run several AI models side by side.
- Carry context from one model to the next.
- Avoid retyping the same background information.
- Call the memory layer during a conversation.
- Compare answers from different models on one question.
Who it is for
- Content creators who draft and refine across models.
- Researchers who need more than one perspective.
- Employees and students working in AI chats daily.
What to watch out for
The extension has to be installed and active, and it depends on the upstream models staying reachable. The time savings described on the site are the product's own claims, so treat them as marketing rather than measured fact. A shared memory layer also means your conversation context passes through the extension, which is worth understanding before you paste sensitive material. Paid terms can change. Processing speed depends on file size and network conditions, so retry later if a task stalls during peak hours. Run one full task end to end first, then expand once you are comfortable with the workflow and the result quality. Save a backup of the original file before large batch jobs, and keep an exported copy of key results in case the page or service becomes temporarily unavailable.
