AI extension for Brave

Brave's own help center says you find the extension in the Chrome Web Store and click Add to Brave, and Brave states it supports nearly all extensions compatible with Chromium. That is why Copilotly points Brave users at the same listing as Chrome.

Brave's privacy settings can affect individual sites, so if something behaves oddly, check the site's Shields settings.

• Sidebar chat that can use the open page, a YouTube video, or a PDF, Word, Excel or CSV file. Chat with PDF.
• Rewrite anywhere, with tone and length pickers and a word-level diff. Rewrite anywhere.
• Bilingual page translation. Page translation.
• Your own API key, never metered by us. Bring your own key.

Brave has its own built-in assistant. Copilotly is separate, with its own account, and adds choice across GPT, Claude, Gemini and others.

Dictation uses the browser's speech recognition. MDN lists support for Chrome, Edge and Opera, but Brave is not in its table, and Brave is a modified Chromium that may handle Google's recognition service differently. We have not tested dictation in Brave, so we will not promise it. Try it and, if it does not start, type instead; everything else on this page works regardless. See dictation.

Free has daily limits; Pro is $6.99/week, $19.99/month or $149.99/year, with a 7-day free trial for first-time subscribers. See free and pricing.

1. Pin the extension. Open the Extensions menu and pin Copilotly so the icon stays visible.
2. Try rewrite on a draft. Select text in any field, pick tone and length, and read the comparison before you replace it.
3. Translate a page. Right-click, "Translate this page", for a side-by-side view.
4. Add your own API key. If you already have one, add it in settings; requests on it are not metered by Copilotly.

Two settings change how well answers fit you. Custom instructions and memory let you tell the assistant who you are and how you like answers, so you stop repeating yourself (see memory and personalization). My Voice learns your writing style, so rewrites sound like you rather than like a generic assistant.

People who pick Brave tend to care about what leaves the browser. Copilotly sends the content you ask about to an AI model, so do not use it on pages you would not paste into any online service. Incognito chats are available in the product.

Brave's community forum has threads where the store shows "Installation is not enabled". If you see that, check Brave's extension and privacy settings, then retry; Brave's help center is the authority on what is blocked. After install, reload open tabs, confirm the extension is enabled at brave://extensions and test on an ordinary website.

If Alt+C conflicts with another shortcut, review shortcuts in Brave's extension settings. And if you would rather not install an extension, the web app at app.copilotly.com offers the chat features.

Different product, different account

Leo is Brave's own assistant. Copilotly is a separate extension from a separate company, with its own account and plans.

Where each tends to fit

Use Leo for what is built into the browser. Use Copilotly for a wider model list (GPT, Claude, Gemini), in-place rewriting and page translation. Details are on the rewrite anywhere and page translation pages.

Is it free?

Yes to start. See the free plan and pricing.

Copilotly runs as a desktop extension in Chrome, Edge, Firefox, Brave and Opera. Arc and Vivaldi also install the Chrome Web Store build. Safari is the exception: no Safari build is published, so the Safari page covers what to use instead.

How was the dictation column checked?

Dictation uses the browser's built-in speech recognition, so it follows the browser, not Copilotly. We took the support data from MDN's SpeechRecognition page. MDN also notes that in browsers such as Chrome the audio goes to a web service for recognition, so it will not work offline. Brave is marked "not verified" because we have not tested it. Rewrite, translation and chat do not depend on speech recognition.

What about phones and tablets?

Desktop extensions do not run in mobile browsers in general. On a phone, use the iOS or Android app, which works on the free plan. Everything is listed on the download page.

Limits belong to your account, so they are the same in the extension, the web app and the mobile apps. Free covers fast models within a token allowance, plus these daily allowances:

What does Pro cost?

Pro is $6.99/week, $19.99/month or $149.99/year, with a 7-day free trial for first-time subscribers. Compare plans on the pricing page.

Do my own API keys count against these limits?

No. Requests on your own key are never metered by Copilotly; see bring your own key.

The same account works everywhere, but the surfaces are not identical.

Rows marked No for the web app and mobile reflect that those features act on the browser page you are viewing. If you rely on them, the extension in Chrome, Edge or Firefox is what you need. For the rest, see all features.

Which shortcuts and menus matter?

• Alt+C opens the sidebar widget.
• Select text to show the rewrite toolbar; Cmd/Ctrl+K opens its command menu.
• Right-click selected text for the context menu, or right-click a page and choose Translate this page.
• Undo and versions restore earlier wording after a rewrite.

How do I turn it off or remove it?

Open brave://extensions, find Copilotly and turn it off or remove it.

Where does my text go?

Content you ask about, including selected text, is sent to the AI model you choose, so avoid using it on anything you would not paste into an online service. Incognito chats are available in the product.

Ask the same prompt twice

Run a question in one model, switch the picker and run it again. A GPT answer and a Claude answer often differ in wording and sometimes in substance, so a second opinion is cheaper than finding the mistake later. Neither is right every time.

Match the model to the job

Use a fast model for quick lookups and small edits, and a premium model when a question needs careful reasoning. Free accounts get 10 premium-model messages a day, so spend them on the questions that matter. Our professional-work comparison is a good starting point.

Check what matters

For anything you will send, publish or act on, read the result and verify the facts and numbers against the original source. Turn on web search when you need cited sources, then open the citations.

Be specific about tone and length

The rewrite toolbar has tone and length pickers. "Friendlier, shorter" is a clearer instruction than a bare rewrite, and you can run it again with a different setting. See rewrite anywhere.

Read the word-level diff

The comparison shows exactly what changed against your original. Approve the parts you like, use undo for the rest, and check that names, dates and numbers are untouched.

Teach it your style

My Voice learns your writing style, and custom instructions and memory tell the assistant who you are and how you like answers. Both are covered in memory and personalization. For a one-off reword with no setup, the free paraphrasing tool works without an account.

Ask specific questions

"What does the author claim, and where is the evidence?" works better than "summarize". Ask for quotes or section names so you can check them against the page.

Work in steps on long pages

Ask for an outline first, then dig into one section. For documents, upload the PDF, Word, Excel or CSV file instead and use chat with PDF. On video pages, ask for a summary and follow up on the part you care about; see YouTube summaries.

Know what leaves the page

Only ask about pages you are comfortable sending to an AI model. Pages behind a login, such as banking or health portals, are better left alone.

Check your organisation's rules first

Many employers restrict browser extensions or AI tools. Ask your IT or security team before installing it on a work profile. This is general guidance, not legal or compliance advice.

Keep sensitive content out

Selected text and pages you ask about go to the model you choose. Do not use it on confidential client data, credentials or personal records unless your policy allows it. Incognito chats and your own API key give you more control, but they do not change what is sent for a request.

Personal profile, personal use

A separate browser profile for personal use keeps work and personal accounts apart. See pricing for plan details.
