Does Notion AI train on my data?
No. As of 2026-07, Notion states that by default neither Notion nor its AI providers (OpenAI, Anthropic) use your content to train AI models. On non-Enterprise plans, providers may hold data up to 30 days before deletion; Enterprise gets zero data retention. Notion AI is covered by SOC 2 Type 2 and ISO 27001.
Why — the first-principles explanation
There is a difference between an AI using your data to answer you and an AI training on your data. To answer, the model must read your note right now — that is unavoidable. Training is different: it means your content gets absorbed into the model's permanent memory, potentially influencing answers for other people later. That second thing is what most people worry about, and it is the thing Notion contractually blocks.
Notion does not run its own frontier model; it sends requests to third parties like OpenAI and Anthropic. So the real protection lives in the contracts Notion signs with them. Notion states that, by default, it and its AI subprocessors do not use customer data to train any models, and the providers are contractually prohibited from doing so. That flips the usual consumer-AI default, where free chatbots often do train on your chats.
The remaining nuance is retention — how long a provider temporarily holds your data before deleting it. On regular plans, providers keep it 30 days or fewer (for abuse monitoring), then delete it. On Enterprise, it is zero retention: nothing is stored with the LLM provider at all. None of this retained data is used for training; it is just a short holding window. So the plain answer is no, your data does not train Notion AI's models.
An example that makes it click
Imagine handing a translator your private letter. To translate it, they have to read it — that is fine. What you fear is that they memorize your letter and start quoting it to their other clients. Notion's rule is: the translator reads your letter to help you, shreds their copy within 30 days, and signs a contract promising never to memorize it or reuse it for anyone else. On the Enterprise plan, they shred it the instant they finish.
That memorizing-for-others part is 'training,' and it is exactly what Notion blocks by contract.
Key facts
- By default, Notion and its AI subprocessors do not use customer data to train any AI models.
- AI providers Anthropic and OpenAI are contractually prohibited from training on your content.
- Non-Enterprise plans: providers retain data 30 days or fewer before deletion; Enterprise: zero data retention.
- Search embeddings are deleted within 60 days of deleting the related page or workspace.
- Notion AI is included in Notion's SOC 2 Type 2 report and ISO 27001 certification, with TLS 1.2+ encryption in transit.

Does Notion AI train on your data? No. And it helps to know the difference between two things. Using your data means the AI reads your note to answer you — that has to happen. Training means your content gets baked into the model's memory and could leak to other users. That's the scary one, and it's exactly what Notion blocks. Notion says that by default, neither it nor its AI providers — OpenAI and Anthropic — use your content to train models, and they're contractually banned from doing so. What about storage? On regular plans, providers hold your data for thirty days or less, then delete it. On Enterprise, it's zero retention — nothing is kept. Notion AI is also covered by SOC 2 Type 2 and ISO 27001. So your workspace stays your own.
