Does Writesonic train on your data?
Writesonic publishes a provider-by-provider table of who may train on your data, and rules it out for all of them. The qualifier is which kinds of model it names.
No opt-out found in this policy

How we read it: The disclosure is the best of its kind found so far: a table naming each model provider — OpenAI, Anthropic, Azure OpenAI, Azure for Anthropic, custom deployments on Azure and AWS — with the training configuration used for each, and the statement that the no-training commitment covers the free tier and trials too. Most policies name no provider at all. One qualifier, in the clause rather than hidden: it covers "any general-purpose, foundation, or large-language model". A narrower model trained for one task is not addressed, and the same policy says Writesonic uses "models developed or fine-tuned by Writesonic".

How to opt out of Writesonic AI training
Plan by plan, from what Writesonic's own policy says about refusing. Where it publishes the steps, they're listed here with the limits they carry. Where there's nothing to switch off, or nothing graded, this says so instead of inventing a menu path.
All plans (including free tier and trials)
Nothing to switch off: Writesonic's policy says training is off here.
