Does QuillBot train on your data?
QuillBot trains on what you type unless you act: extension users get two switches, website users must email privacy@quillbot.com, and only Team Plan users are excluded by default.
Opt-out is sold, not offered

How we read it: Re-graded from E on 18 September 2026 after Learneo, QuillBot's owner, replied. The policy claims everything it collects and only gestures at controls: services "may offer you additional privacy settings or controls". The help centre documents two switches, but for the browser extension only. For the website tools the route is the one Learneo gave in its reply: users "can submit a request to object or opt-out of the use of text inputs or training purposes by email to privacy@quillbot.com". Published nowhere, so recorded as the company's statement; an email is the way out. Training data gets "automatic pseudonymization of certain sensitive fields", a qualified promise.
opt out, opt-out, settings, controls, object, revoke consent, Team Plan, privacy@quillbot.com
What the document does offer
- in the policy: "Our Services may offer you additional privacy settings or controls, such as the ability to opt-out of certain activities like storage or use of inputs for AI model training" — names no setting, and "may offer" commits to nothing
- in the policy: the Team Plan carve-out, definite where the individual control is not: "This default setting applies to all Quillbot Team Plan users and does not require any opt-out or action from the Team Plan Owner or users"
- in the help centre (help.quillbot.com, captured 2026-09-18): two extension controls, "(1) allowing Quillbot to store text inputs (all users) and (2) allowing Quillbot to use text inputs to train the models that power our AI tools (available to account-holders)", reached via Extension Settings > View All Settings > Data and Privacy. Nothing for the website tools.
- in Learneo's reply of 2026-09-18: website users "can submit a request to object or opt-out of the use of text inputs or training purposes by email to privacy@quillbot.com" — published nowhere
- support.quillbot.com, where the policy defers the detail, is Disallow: / in its robots.txt; help.quillbot.com, where the answers actually are, is not
Why none of it applies: The website tools have a way out and it is an email address, stated by the company in reply to this site and published in none of its documents. The extension has two switches the help centre names and locates. The Team Plan is excluded by default. D rather than E because a route now exists for an individual; D rather than C because for most users it is a letter to the company, and the help centre never says which way the extension's training switch ships for a new account-holder.
"For extensions users on versions 4.37.0 or above, we offer two data controls to opt out of: (1) allowing Quillbot to store text inputs (all users) and (2) allowing Quillbot to use text inputs to train the models that power our AI tools (available to account-holders)."

How we read it: The help centre names the switches and where they live, and says storage "will be on by default for everyone". Which way the training switch ships for a new account-holder it does not say: existing users' "prior consent setting will be applied to the new control for training", and nothing is said about anyone else, so the default is undisclosed. Website users get neither switch. The same page promises the desktop app the same controls "in the future".
"When you use Quillbot's premium services with a Team Plan, we will use and store your inputs to provide our Services as described in this policy, but we will not use your text inputs for the purposes of training our AI models ."

How we read it: The exemption is explicit and is the other half of the paywall: the same document that claims all collected data for training carves out Team Plan text inputs from it. Note the limit — it covers text inputs, and the policy still says inputs are used and stored to provide the service.
What QuillBot said when we showed them this
Corrected us“While the excerpt of the Learneo Privacy Policy (applicable to Quillbot) included in your inquiry is accurate and applicable, we would like to help clarify your “finding” statement. [...] For extensions users on versions 4.37.0 or above, we offer two data controls to opt out of [...] allowing Quillbot to use text inputs to train the models that power our AI tools. Users of any of our website-based tools can submit a request to object or opt-out of the use of text inputs or training purposes by email to privacy@quillbot.com. [...] Quillbot does not train on any text inputs from Team Plan users.”

How to opt out of QuillBot AI training
Plan by plan, from what QuillBot'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.
Website tools (free and individual Premium)
Yes, but not self-serve: QuillBot makes you contact support.
Browser extension 4.37.0 or later (account-holders)
Yes. QuillBot has a self-serve setting.
- Click the QuillBot extension icon to open Extension Settings, or open the Popup Menu.
- Click View All Settings.
- Open the Data and Privacy menu and switch off the control for using your text inputs to train the models.
The training control is offered to account-holders only; the storage control to everyone. Storage is on by default for all; the training default for a new account-holder is not stated.
Team Plan (paid)
Nothing to switch off: QuillBot's policy says training is off here.
