Private AI models, trained on your own data.
What you share with a public AI goes to the company that runs it. Monotonic gives you an AI that answers from your own documents and keeps up as they change. Your data is stored in isolation inside Monotonic and never sent to a public AI provider.

Common questions
What is a private AI model?
A model that runs isolated from other customers and is only ever trained further on your own data. Nobody else's questions or documents reach it, and yours never reach anyone else's.
Which models does Monotonic use?
Today every plan runs Qwen3 4B, a small AI model that runs entirely inside Monotonic. Pro and Business get larger, more capable models as each one passes our quality tests.
Does my data leave Monotonic?
No. Files are sent over an encrypted connection and encrypted as soon as they reach us. They are cleaned, stored and trained on inside Monotonic, and every answer is generated there.
How much does it cost?
Plans start at $29 a month, plus applicable sales tax. The price is per account, not per person: Starter is for one person, Pro includes up to 5 people and Business up to 25. Pricing and limits are in the pricing section above.
