"Does ChatGPT read my chats?" The short answer is: Yes, unless you opt out.
Most public AI tools use your inputs to train their next model. If you paste proprietary code or sensitive customer data into a standard chatbot, that data effectively becomes part of the public brain.
The "Zero-Training" Standard
For businesses, this is unacceptable. You need tools that adhere to a "Zero-Training" policy. This means the AI processes your data to give an answer, but instantly forgets it afterwards.
1. PlusB (Enterprise Privacy)
PlusB was built for professionals who cannot leak IP. We have a contractual Zero-Training policy.
How we protect you:
- No Training: Your data never enters our model training set.
- Encryption: All chats are encrypted at rest and in transit.
- Siloed Memory: Your "Project Memory" is isolated to your workspace. Meaning, one user's project context cannot leak to another user.
2. ChatGPT Enterprise
If you pay for the Enterprise tier (not the $20 Plus tier), OpenAI promises not to train on your data. However, this tier typically requires a minimum number of seats and a hefty annual contract.
3. Local LLMs (Llama 3, Mistral)
The ultimate privacy is running the AI on your own laptop. Tools like Ollama or LM Studio allow you to download open-source models comfortably.
The Tradeoff: Your laptop will get hot, and the models aren't as smart as GPT-5 or PlusB's cloud models.
Checklist: Before you paste data
- Check the "Terms of Service" search for "training".
- Look for an "Opt-out" switch in Settings (ChatGPT has one).
- Anonymize names and sensitive numbers manually before pasting.
Verdict
If you are coding or working with sensitive docs, do not use free public tools. Use a secure workspace like PlusB or run local models.
