Private Mode on Perspective AI: Encrypted, Browser-Only AI Chat

TL;DR: Private mode on Perspective AI keeps conversations out of server storage entirely: history is encrypted locally in your browser, requests are relayed statelessly to the model, and no server copy exists to delete. The platform commits to not logging, retaining, or repurposing conversation content, and meters usage by amount, not by reading what you asked. Unlike most privacy claims, this one is built to be checked: the Transparency page invites you to open your browser's network panel and verify what loads.

Private mode on Perspective AI keeps your conversations out of server storage entirely: history is stored only in your browser, encrypted locally, and each request is relayed statelessly to the model you chose, with the server metering credits used but not retaining the prompt or the reply once the response is delivered. That is the definition. The rest of this page does something most privacy pages refuse to do: it maps every claim to a published source you can check yourself, because a privacy promise you cannot verify is just a badge. This is part of our use cases section, alongside the workflows the privacy actually protects.

One position up front: privacy on Perspective AI is a property of the product, not a paid add-on. The platform is built so you can use frontier and open models without your conversations being logged, mined, or used to train anyone's model. You will not find absolute privacy claims anywhere on this page, because absolutes are exactly the kind of claim you cannot verify. What you will find is mechanisms, and where to check them.

Two ways to chat: standard mode vs private mode

Standard mode is the right default when you want your threads to follow you between your laptop and your phone. Private mode is for the conversations that should not exist anywhere but your own device. Both run against the same catalog of 60+ AI models, so going private does not mean downgrading to a weaker model.

Who actually needs the private option? More people than the phrase "sensitive conversations" suggests. Anyone drafting around confidential work, asking health or legal questions they would not put in an email, thinking through a negotiation, or simply working through something personal has a conversation that does not belong in anyone's retention policy. The useful mental model: standard mode is a notebook that syncs, private mode is a whiteboard you erase, and you choose per conversation rather than per product.

What private mode actually does

Three mechanisms, stated the way the docs state them:

• Stored only in your browser. Private-mode conversations are encrypted locally, per account, and never written to platform storage.
• Relayed statelessly. The server passes your request to the chosen model to get a response and meters the credits used, but does not retain the prompt or the reply once the response is delivered.
• Yours to erase. Because the history lives on your device, clearing it removes it. There is no server copy to ask anyone to delete.

The third point is the one to sit with. Most "delete my data" flows are requests: you ask, the company processes, you trust the result. In private mode the deletion question does not arise on the server side, because the design gives the content no server-side home in the first place.

What necessarily leaves your browser

Being honest about this is part of the point. To get a model's answer, your prompt has to reach the model that produces it. That is inherent to inference, in private mode or not, on Perspective AI or any other AI product. A privacy page that implies otherwise is selling you something.

What Perspective AI commits to is the part it controls: the platform itself does not log, retain, or repurpose that content, and private mode adds no server-side record on top. What the platform does keep, in any mode, is the minimum needed to run your account: who you are, your subscription and credit balance, and the metered quantity of usage. Quantity, not content: the meter counts how much you used, not what you said.

Does Perspective AI log or train on your conversations?

The commitment is deliberately structural rather than a promise you take on faith:

1. Usage is metered by amount, not by reading what you asked.
2. Private-mode content has no server-side home to leak from.
3. You are never deplatformed for what you ask an open model.

The order of those three points is the argument. A promise says "we will not read your chats." A structure says "the billing system counts tokens, not sentences, and the private-mode transcript it would need to read was never written to our storage." The second kind of claim ages better than the first, because it depends on how the system is built rather than on anyone continuing to behave well.

Where a guarantee depends on infrastructure still being rolled out, the docs describe it as the mechanism it uses, not as a finished audit. That caveat is published in the privacy docs themselves, and repeating it here is deliberate: overstating a privacy posture is how trust gets burned.

Verify it yourself: every claim, and where to check it

This is the part that separates verifiability from marketing. Each claim on this page traces to a page you can read, and the tracking claims trace to something better: your own browser.

The Transparency page opens with an invitation, not a badge: open your browser's network panel and check, because the page is meant to match reality. Take it up. The whole check runs about two minutes:

1. Open app.perspectiveai.xyz in a fresh tab and open your browser's developer tools before the page loads.
2. Switch to the Network tab and reload. Watch which domains appear.
3. If you are in the EEA or UK, note what loads before you touch the cookie banner: nothing from Google, no cookies, no pings, because the default is deny.
4. Compare what you saw against the Transparency page's "what we load" and "what we never do" lists.

What you see should match what the page says. If it ever does not, that is a bug report the platform has explicitly signed up to receive, and that willingness to be caught is worth more than any privacy badge, because a badge only certifies that someone paid for a badge.

What runs alongside your conversations

Separate from chat content, the site and app measure traffic to run the business, and the posture is specific rather than hidden: first-party attribution captured server-side and never sold, cookieless aggregate analytics with no personal data, and error monitoring with session replay off. Google Analytics and Google Ads load only after you accept the cookie banner, and ad conversions are reported only for users who consented to ad measurement. You can turn analytics off entirely on the Transparency page.

Compare that with the industry default of behavioural autocapture and pre-consent pixels, and the difference is the thesis of this page: the interesting question is never whether a company claims privacy, it is whether you can check. Every AI product you evaluate deserves the same two-minute network-panel test described above. Run it on the tools you use today and see how many pass it before the cookie banner is even answered.

Where private mode fits in a privacy stack

If you are choosing an AI tool on privacy grounds, put private mode in context. Our ranking of the best AI for privacy covers the whole field, including tools that go further on device-level guarantees and what you trade away to get that. The most common comparison we get asked about is Venice AI, whose privacy architecture we examined in our Venice AI safety and privacy review. The short version of Perspective AI's angle: verifiability over vocabulary, plus the things privacy-first tools usually lack, like agents with memory when you want continuity and private mode when you do not.

That last pairing is the practical takeaway. Privacy is not one setting, it is a per-conversation choice: standard mode when you want your history to follow you, private mode when the conversation should live and die in your browser. One subscription, both behaviors, and a published page that invites you to audit it.
