Is Perplexity Comet safe to use?
Perplexity’s Chromium-based web browser. It works like an ordinary browser, but adds an assistant that can summarize the page you are on, answer questions about open tabs, search your history when you allow it, and act on websites or connected services. It is a different privacy object from Perplexity’s search and chat product.

Does Perplexity Comet train on what you type?
Yes, unless you switch it off — and you can.
Can you turn Perplexity Comet's training off?
Assistant access: Open Settings → Privacy and security → Comet Assistant. You can disable the assistant, stop it using browser history, or block it on specific websites. Perplexity uses a bank site as its own example. When an agent first asks to run, choose “Allow this time only” or “Don’t allow” until you understand the task. Model training: Open your Perplexity Account settings → Preferences → AI data retention, then switch it off. Perplexity says this affects data collected after the opt-out; it does not remove data already used for training. Review Settings → Memory separately and delete saved memories or search history you do not want reused. Browser hygiene: Review comet://settings/privacy. Third-party cookies are allowed by default, so change Settings → Privacy and security → Third-party cookies if you want them blocked. Use Incognito when you do not want Comet to save local history, cookies, or cache, but remember that Incognito does not stop network-level or website tracking. Connect Gmail or Calendar only when you want the assistant to work with those accounts.
Is what you put into Perplexity Comet private?
Most ordinary browsing data stays on your device by default, including visited sites, cookies, open tabs, downloads, site permissions, passwords, and autofill data. Perplexity says Comet Assistant does not upload your full history, every open tab, passwords, or text you type into a website just because the browser is open. When you ask for a task that needs context — such as summarizing the current page, using @tab, finding something in your history, or working with connected email or calendar — Comet sends the context needed for that request to Perplexity. Its Help Center says page, tab, or history context used by the assistant may be kept for up to 30 days for Library and query-history features, then deleted automatically unless you remove the expiry timer. A synced account changes the picture. Perplexity’s Privacy Notice says that, depending on your settings, it records browsing history and tracks use and engagement when you use Comet with a synced Perplexity account. That is broader than the older Comet FAQ, which still describes cloud history sync as a future opt-in feature. The legal notice is the safer document to follow. Incognito stops Comet from saving local history, cookies, and cache for that session, but it does not make you invisible to Perplexity, your internet provider, an employer, or the sites you visit. Training follows the Perplexity account rules. For Free, Pro, and Max accounts, AI Data Retention is on by default. Perplexity says some data may be used to train AI models and improve search unless you turn that setting off; the opt-out applies to data collected after you change it. This does not mean every locally stored URL is automatically training data. It means queries, memories, and other content that reaches Perplexity may be used under the consumer account setting. Enterprise data is excluded from model training. Perplexity also says linked Email Assistant contents are not used to create, train, improve, or fine-tune its models.
So, is Perplexity Comet safe to use?
Mostly, with care. We currently rate Perplexity Comet "Use With Caution" (privacy risk: Medium). Worth reading the points above before you share anything personal.
Our take
“A browser used to be a window. This one comes with a helper who can look through the window when I ask. Useful, certainly. It is still not getting the bank tab or the family inbox without a very specific invitation.”
