Confidentiality & security
Is client data used to train AI models?
It depends on the tool, and the difference matters enormously for lawyers. Many consumer AI tiers reserve the right to use your inputs to improve their models, which is a poor fit for confidential client material. Legal-grade AI should commit, in its contract, not to use your content to train any model. Always confirm that no-training commitment in writing before putting client matter into any AI tool.
Why training on your data is a problem
Content fed into a model that learns from it leaves your control and can, in principle, influence outputs delivered to other users. For ordinary text that may be acceptable; for privileged client material it is not.
The safe default for a law firm is that nothing you put into an AI should ever become training data.
Consumer tiers versus legal-grade tools
Many consumer AI tiers train on user inputs by default unless you opt out, and make no confidentiality commitment to you. Legal-grade tools should do the opposite: commit contractually not to train on your content, and keep it confidential.
The marketing language is not enough — the commitment needs to be in the agreement you sign.
What to confirm before you upload
Ask for a written, contractual commitment that your content is not used to train or fine-tune any AI model, and check it covers everything you put in — documents, prompts and outputs. If the answer is vague, treat that as the answer.
Frequently asked questions
Does ChatGPT train on my conversations?
It depends on the tier and your settings — some consumer use trains on inputs unless you opt out. Do not assume; check the terms, and for client work prefer a tool with a contractual no-training commitment.
How do I stop my data from training an AI?
Use a tool that commits, in its contract, not to train on your content, and confirm that commitment in the agreement rather than relying on a settings toggle.
Does Quillio train on client data?
No. Quillio does not use client content to train any AI model — it is a contractual commitment.
