Shared AIs: How Your Documents Are Training Future Models (Without Your Consent)

The Best-Kept Secret of Free AIs

Have you ever wondered why ChatGPT, Claude, and other AI services offer such powerful free versions? The answer is simple: you are the product.

How AI Training Works

Large language models (LLMs) like GPT-4 or Claude need enormous amounts of data to improve. This data comes from:

1. Public internet: Books, articles, source code
2. Synthetic data: Artificially generated
3. User interactions: What you write and upload

The Fine Print Nobody Reads

Let's review the privacy policies of major services:

OpenAI (ChatGPT)

"We may use Content to improve our Services, for example, to train the models that power ChatGPT."

Anthropic (Claude)

"We may use conversations to improve our models and services."

Google (Gemini)

"Conversations may be reviewed by humans and used to improve our products."

Real Cases of Leaks

• Samsung (2023): Employees uploaded confidential source code to ChatGPT. Samsung had to ban the use of external AIs.
• Amazon (2023): Detected that internal code was appearing in ChatGPT responses to other users.
• Law firms (various): Cases where client information appeared in unexpected contexts.

The "Memorization" Problem

AI models can "memorize" fragments of the data they were trained on. This means:

• A contract you uploaded could be partially reproduced
• Personal data could appear in responses to other users
• Strategic information from your company could be accessible

What Does "Opt-Out" Mean?

Some services offer the option not to use your data for training:

• ChatGPT Plus: You can disable it in settings
• Claude Pro: More restrictive policy by default
• Enterprise versions: Generally don't train with your data

But even with opt-out:

• Do you trust it's being followed?
• What about already processed data?
• How do you verify it's really not being used?

The Alternative: AIs That Respect Your Privacy

works differently:

1. Pre-trained model: We use already trained models, we don't need your data
2. No storage: Documents are processed and deleted
3. No feedback: Your information never improves our models
4. Auditable: You can verify exactly what we do with your data

Checklist: Is It Safe to Upload This Document?

Before using any AI with a document, ask yourself:

• Does it contain confidential company information?
• Does it include personal data from third parties?
• Does it have confidentiality clauses?
• Could it harm someone if leaked?
• Would it violate any NDA agreement?

If you checked any box, don't use shared AIs.

Conclusion

AI is an incredibly useful tool, but the "free in exchange for your data" model has a hidden cost that many companies cannot afford. offers an alternative where privacy is non-negotiable.
