Which AI Tools Train on Your Data?
Find out which AI tools train on your data and which do not. Learn how API access can bypass data training, and how Krater.ai uses transparency badges.
Most major AI companies — including OpenAI, Google, and Meta — may use data from their free and consumer chat products to train future models, unless you opt out. Anthropic (Claude) generally does not train on user conversations. Third-party platforms that access AI models via API — like Krater.ai — bypass consumer data training policies because API usage is typically excluded from training data. Krater.ai displays transparency badges on every model so you always know whether your data may be used for training.
Which Major AI Companies Train on Your Data?
| Company | Consumer Product | Trains on Chat Data? | API Data Training |
|---|---|---|---|
| OpenAI | ChatGPT | Yes (opt-out available) | No (excluded by default) |
| Gemini | Yes (activity settings) | No (excluded by default) | |
| Anthropic | Claude | No (by default) | No |
| Meta | Meta AI | Yes | Llama is open-source |
| Mistral | Le Chat | Varies by plan | No (excluded by default) |
How Third-Party Platforms Bypass Data Training
When you use ChatGPT directly at chat.openai.com, your conversations may be used to improve future GPT models. However, when a third-party platform like Krater.ai accesses GPT via OpenAI's API, the data handling is different.
Most AI providers explicitly state that API data is not used for training. This means:
- Your conversations through Krater.ai go through the API, not the consumer product
- API terms of service typically exclude user data from model training
- Your prompts and responses are processed but not stored for training purposes
This is one of the key advantages of using a third-party AI platform over using each AI provider's consumer product directly.
Krater.ai's Transparency Badges
Krater.ai displays clear badges on every AI model in the platform, indicating:
- Data training status — whether the model provider may use your data for training
- Privacy level — the overall privacy posture of the model
- Environmental impact — the estimated energy footprint of the model
These badges give you the information to make informed choices about which model to use for sensitive or personal content. No other major platform provides this level of per-model transparency.
Best Practices to Protect Your Data
- Use API-based platforms — third-party apps like Krater.ai that access models via API generally provide better data protection than using consumer products directly
- Check opt-out settings — if you use ChatGPT or Gemini directly, review your privacy settings and disable data training where possible
- Avoid sharing sensitive data — regardless of training policies, do not share passwords, financial details, or highly confidential information with any AI
- Use models with strong privacy defaults — Claude and models accessed via API have the strongest default privacy postures
- Check transparency badges — on Krater.ai, check the badge before using a model for sensitive topics

Frequently Asked Questions
Does ChatGPT train on my conversations?
On the free tier and consumer products, yes — unless you opt out in settings. When accessed via API (as through platforms like Krater.ai), OpenAI does not use your data for training.
Is Claude safe for private data?
Claude has one of the strongest privacy defaults among AI providers. Anthropic does not train on user conversations by default, whether through the consumer product or API.
How do I know if a model trains on my data?
On Krater.ai, every model displays transparency badges indicating its data training status. On other platforms, you need to read each provider's privacy policy individually.
