Your context should stay with you.

Sure, ChatGPT remembers some things. Claude keeps project context. But try switching between them. Or migrating your data. Or using your GPT-4 context in Claude. Your memory lives in their platform. Moving means starting over.

AI Amnesia

Starting over. Every. Single. Time. Hours of context-building, gone with each new AI. Your AI's memory is limited, fragmented, and locked to one platform.

Locked to One Model

Want to try Claude for coding and GPT-4 for writing? Your context doesn't come with you. Each model is a fresh start, every time you switch between models.

Data You Can't Own

What has your AI learned about you? Good luck finding out. ChatGPT won't show you. Claude gives you a summary. Your memory and context should belong.

AI memory, solved

Your memory shouldn't be trapped in ChatGPT.

Switch between Claude, GPT-4o, or Gemini mid-conversation. Compare responses. Let Onoma route to the best model for each task.

Shared Memory

One context layer across 16 models. Switch providers, keep your history.

Frequently asked questions

Two reasons: data control and provider portability. When you use ChatGPT or Claude directly, your conversations may be used to train their models. Your context is also locked inside that one platform. Switch providers and you start from zero. Onoma gives you one persistent memory across 14+ models from 7 providers. Your context follows you everywhere, you can see exactly what's stored, and your data stays yours.
You control what's stored and what's shared. View, edit, or delete any memory. Unlike using AI providers directly, where your data may be used for training, Onoma keeps your context private and portable. Enable EU-only mode to restrict to EU-hosted models. Turn on PII protection to strip personal information before it reaches any AI. Export everything anytime. Your data, your rules.
Onoma supports 14+ models from 7 providers including OpenAI, Anthropic, Google, Mistral, xAI, and more. Free users get access to 8 models, Ambassadors unlock all models plus new ones as they're added. See the full current list at askonoma.com/models.
Spaces organize your context automatically. Work stays separate from personal projects. Client A stays distinct from Client B. You don't tag or sort anything. Onoma does it for you. Relevant context surfaces when you need it, stays hidden when you don't.
Anyone who uses multiple AI tools and is frustrated with rebuilding context every time they switch providers. Privacy-conscious professionals who want control over their data and don't want their conversations training AI models. Anyone who values knowing exactly what AI knows about them, with the ability to edit or delete it.
Yes. Your memory travels with you. Switch providers mid-conversation, regenerate an answer with a different model to compare, or try Grok today and Claude tomorrow. Your context follows. Zero switching cost.
Models are the AI brains (like GPT-4o, Claude Sonnet, Gemini Pro). Providers are the companies that make them (OpenAI, Anthropic, Google). Onoma lets you switch both freely. Use a fast model for quick questions, a powerful one for complex tasks, all while keeping your context intact.
No. Your conversations and context are never used to train any AI models. When you use ChatGPT or Claude directly, your data may contribute to their training. With Onoma, you maintain complete ownership and control over your data.
Before any data reaches an external AI model, Onoma detects and anonymizes personally identifiable information using Presidio, Microsoft's open-source PII detection engine. Data like names, emails, addresses, and phone numbers are replaced with tokens before leaving your device. The AI sees [PERSON] and [EMAIL] instead of your actual data.

Stop re-introducing yourself to AI.

One memory across every AI model, entirely yours. If you're ready for AI memory that actually remembers you, welcome home.
