Frequently asked questions
How do usage limits work?
Pro includes a monthly allowance with a daily cap, so one busy day can't use up the month. Capable models use more of it per reply than fast ones. Learn more
How does the trial work?
Seven days of Pro for €1.00. After that, Pro renews at €29.99 every month — cancel anytime. Learn more
Which AI models can I use?
Many, across providers (Claude, GPT, Gemini, Grok, DeepSeek and more). Use the model switcher at the top of a chat to change models mid-conversation.
What does Pro include?
Pro unlocks every premium model, image generation, web search, Deep Research and file analysis. It includes a monthly usage allowance with a daily cap — how far it goes depends on the model you use.
Can I change my plan later?
Yes. Manage or cancel your subscription anytime from Settings → Account.
How do I cancel my subscription?
Open Settings → Account and choose Cancel subscription, or use the Cancel Subscription link at the bottom of the page. Your access continues until the end of the period you've paid for.
How do attachments and PDFs work?
Attach images or documents to a message, or add files to a project's knowledge base. Text (including from PDFs) is extracted and given to the model as context.
