Secret Chat AI
in Your Browser's Sidebar

Launch Private Chat

An AI assistant is most useful at the exact moment a question appears — while you are reading, writing, comparing or deciding. The Secret Chat AI browser extension puts the whole app into your browser's sidebar, so the chat is one click away and stays open beside whatever you are doing: ask, read the answer, keep working. Same anonymous chat, same models, same account — no switching to another tab, no losing your place. This is one of the features of Secret Chat AI, the AI aggregator.

The sidebar sits beside whatever you are reading — type a question the moment it comes up, without leaving the page.

What the extension is

The extension is a thin shell: it opens the Secret Chat AI web app — the same one that runs at app.secret-chat.ai — in the browser's side panel. There is no separate "extension version" of the app, no separate account and no separate history: you are signed into the same account and see the same conversations as in a normal tab, and your chat history keeps living in your own browser, not on our servers.

It is also entirely free. Nothing is sold inside the extension — no purchases, subscriptions or unlocks. The service's free daily quota works in the sidebar exactly as it does on the website, with no account needed, and if you ever buy credits, that happens on this website, in a normal tab.

Why a sidebar beats another tab

A chat in a tab competes with your work; a chat in the sidebar sits beside it. The panel stays open while you move between tabs, so you can draft an email on the left and shape a paragraph on the right, read a long article and ask questions as they come up, or keep a running conversation going through a whole working session without ever hunting for the right tab.

And because Secret Chat AI is an aggregator, this one panel replaces not one AI tab but several: ChatGPT, Claude, Gemini, Grok, DeepSeek USA and Perplexity live behind one model picker, on one balance, with image generation and the AI Council included. One sidebar instead of six logins.

It cannot read the page you are on

Many popular AI sidebar extensions ask for permission to read and change the websites you visit — reading the page beside them is what their "summarize this page" features are built on. This extension asks for exactly two domains: its own app and its own API. There is no content script, nothing is injected into any page, and nothing from the sites you browse passes through the extension. When you install it, check the permission prompt — that short list is the entire ask.

The honest consequence: it will not summarize your current tab automatically, because it cannot see your current tab. Paste the text or attach the PDF instead — the models read both. That is the deliberate trade: a sidebar that cannot watch your browsing is a sidebar you do not have to trust about your browsing.

The privacy of the chat itself is the app's, unchanged in the sidebar: no profile is built about you, no conversation is associated with you, and your queries reach the AI providers anonymously. The honest limit is unchanged too — Secret Chat AI removes you from your queries, it does not remove the data from your messages, so what you type still reaches the model you chose verbatim.

How to install and open it

Chrome

Install it from the Chrome Web Store, then click the extension's icon in the toolbar — the chat opens in Chrome's side panel, beside the page (Chrome's settings let you choose which side it sits on). Pin the icon (the puzzle-piece menu → pin) so it is always one click away.

Firefox

Install it from Firefox Add-ons, then click the toolbar icon, or open it via the menu: View → Sidebar → Secret Chat. Firefox lets you keep the sidebar on whichever side you prefer.

Microsoft Edge

Install it from Microsoft Edge Add-ons, then click the extension's icon in the toolbar — the chat opens in Edge's sidebar. (Edge can also install the Chrome Web Store version if you allow extensions from other stores, but the Edge Add-ons build is the native one.)

What people use it for

  • Writing beside the work — draft the difficult reply in the panel while the message you are answering stays on screen, then paste the result over.
  • Reading with questions — keep a long article, paper or contract open and ask about the parts that need untangling as you reach them (paste the passage in — the sidebar cannot see the page itself).
  • A second opinion on demand — run a claim you just read through the AI Council without leaving the page it came from.
  • Everything the app does — projects, threads, custom instructions, attachments and voice input, export — the sidebar is the full app, not a cut-down one.

Frequently Asked Questions

Is the sidebar extension free?
Yes, entirely. Installing it costs nothing, and there are no purchases, subscriptions or unlocks inside the extension — it is a free client for the same web service. The service itself has a free daily quota that needs no account, so you can install the extension and start asking questions right away. If you later want more than the daily quota, credits are bought on this website, never inside the extension.
Can it read or summarize the page I am viewing?
No — and that is deliberate. The extension has no access to your tabs, so it cannot read the page next to it. To work with a text or document, paste it into the chat or attach the file; every model that can read it will. A sidebar that cannot watch your browsing is a sidebar you do not have to trust about your browsing.
Will I see my existing account and chats in the sidebar?
Yes. The sidebar loads the same app from the same address, so you are signed into the same account and see the same chat history as in a normal tab. Your conversations still live in your own browser, not on our servers — the panel is just another window onto them.
Can I run the AI Council from the sidebar?
Yes — the sidebar is the full app, so one question can go to two, three or four models from different companies at once (the AI Council). The models are asked in parallel, the first answer appears as soon as the fastest one finishes, and a referee then compares the answers claim by claim, so you read a ready conclusion instead of reconciling several long replies by hand. Two honest notes: agreement between models is evidence, not proof — they share training data and can be wrong together, so the reliable signal is where they disagree — and a council widens where your text travels, since it reaches every model on the panel plus the referee, so the advice to leave identifying details out of a message applies with more force, not less.
Which browsers does it work in?
Desktop Chrome, Microsoft Edge and Firefox — the three desktop browsers the extension is built for. On any other browser, and on phones, the app itself works as a normal tab or installed web app at app.secret-chat.ai.
