AI workspace for Germany and the EU
Every AI. One bridge.
Use models from OpenAI, Anthropic, Google, Mistral AI and Octodus in one workspace, with one account and monthly usage limits you can see before you pay.
5 modelsfrom €9.90 / monthlimits shown upfront
One account in front of several AI models.
OpenBridge connects to each provider through its official API. You sign in once, choose a model for each conversation and keep track of one allowance.
-
Create one account
Sign up with your email. There is no separate subscription to manage with each AI company, and no shared logins.
-
Pick the model for the task
Switch between OpenAI, Claude, Gemini, Mistral and Octo in the model picker. The workspace shows which provider and model answer each message.
-
Watch your allowance as you go
Every plan has a monthly allowance of messages and tokens, counted on our servers. When it is used up, new requests pause until the next billing period or a plan change.
Built for daily work, not for hype.
-
One workspace
All conversations in one place
History, new chats and model choice live in one interface, whichever provider answers.
-
Right model
Choose per conversation
Use a fast model for quick drafts and a stronger one for long documents, without switching apps.
-
Transparent usage
Limits in plain numbers
Messages, tokens and request rates per plan are published below. No plan is unlimited.
-
Privacy-conscious
Keys and requests stay server-side
Your prompt goes only to the provider you pick. OpenBridge does not use your conversations to train models.
Five model families, one picker.
Each model runs through its provider's official API under that provider's terms. Availability depends on the provider and on our configuration.
OpenBridge is independent and not endorsed by these providers. A subscription does not include ChatGPT Plus, Claude Pro, Gemini Advanced or any other consumer plan.

Draft launch pricing. Prices are per month in EUR. Limits are configurable and may change before public launch; the final VAT presentation will be confirmed before launch.
Access is subject to plan limits, fair use, model availability and each provider's terms. A token is a piece of text of roughly four characters in English; long conversations use more tokens per message.
Payments are processed by Stripe. Until launch, checkout runs in test mode and no real charge is made.
Questions before you start.

Which models can I use?
Models from OpenAI, Anthropic (Claude), Google (Gemini), Mistral AI and Octo by Octodus. The workspace only offers models that are connected and available at that moment. The current model of each family is listed in the Models section above.
Is this the same as ChatGPT Plus or Claude Pro?
No. OpenBridge is an independent service that uses the providers' official APIs. Your subscription does not include any provider's consumer plan, and OpenBridge is not affiliated with or endorsed by OpenAI, Anthropic, Google or Mistral AI.
How do the usage limits work?
Each plan has a monthly number of messages and tokens, a per minute request rate and a maximum message length. We count usage on our servers and show what is left in your account. When you reach a limit, new requests pause until the next billing period or until you move to a bigger plan.
How is billing handled?
Plans are billed monthly in EUR through Stripe. Your plan becomes active only after Stripe confirms the payment. We never see or store your full card details.
What happens to my data?
Your prompt and the conversation context are sent to the provider of the model you chose, and the answer is stored in your conversation history. API keys stay on our servers. OpenBridge does not train models on your conversations. You can delete conversations and request deletion of your account at any time. Details are in the Privacy Policy.
Can I cancel?
Yes, from your account at any time. Your plan stays active until the end of the period you have paid for and is not renewed after that.
Is OpenBridge available in German?
The interface is in English at launch. German is planned. You can write to any model in German.
