A free AI assistant for your browser: what you get without paying

You need a free account for the extension, web app and mobile apps. It costs nothing and asks for no card. With it you get:

• Fast models on every chat, within a token allowance. They handle most everyday questions, summaries and rewrites.
• 10 premium-model messages a day. When they run out, the chat continues on the provider's fast model rather than stopping.
• 5 web searches a day with cited sources. See web search.
• 3 images a day. See image generation.
• 1 deep research run a day. See deep research.
• 3 full-page translations a day. See page translation.
• 5 voice drafts a day. See dictation.

The sidebar, rewrite-anywhere toolbar, chat with files, YouTube summaries and memory are part of the product on the free plan; the limits above are what is capped. Allowances are per day.

If you do not want to sign up at all, the free tools run without an account. Each visitor gets 5 runs a day, on a fast model, with up to 6,000 characters in a long field. The text you paste is sent to the AI model to produce the result.

• Writing: paraphrasing tool, text summarizer, tone changer, email writer.
• Career: cover letter generator, resume checker, resignation letter generator, counter offer letter generator, PIP response letter generator, appeal letter generator.
• Content: SEO content checker.

The tools are a way to get one job done. The extension is for doing it on the page you are already on.

Each model has a tier. Fast models are on every plan, premium models draw on your 10 daily messages, and frontier models need Pro or your own key. The models page lists them all, and the per-model pages go into detail:

• ChatGPT: GPT-6 Luna (fast), GPT-6.1 Terra and Sol (premium), GPT-6 Astra (frontier).
• Claude: Claude Haiku 5.5 (fast), Claude Sonnet 5.5 (premium), Claude Opus 5.5 and Fable 5.1 (frontier).
• Gemini: two Flash models (fast), Gemini 3.1 Pro (premium), Gemini 4 Argon (frontier).
• Grok, DeepSeek and Mistral: one fast and one premium model each.

So if you are looking for a free ChatGPT alternative in a sidebar, this is it: a mix of providers in one menu, with a daily budget for the strongest ones.

If you already have an API key from OpenAI, Anthropic, Google or another provider, you can use it in Copilotly. Requests on your own key are never metered by Copilotly, whatever the model, and that includes frontier models on the free plan. You pay the provider directly. See bring your own key for the setup.

This suits people who use AI heavily but do not want a subscription, as long as they are happy to manage an API account.

Pro removes the premium limit and raises every daily allowance, and adds the frontier models and PDF export of chats. It is $6.99/week, $19.99/month or $149.99/year, with a 7-day free trial for first-time subscribers. The table below shows each limit side by side, and the pricing page has the details.

You do not need Pro to judge the product. Use the free plan for a week on real work. If you keep running into the premium limit or want frontier models, upgrade then.

Copilotly is an independent assistant. It is not affiliated with Microsoft Copilot, OpenAI, Anthropic, Google or any model provider; it uses their models through their APIs. If you are comparing it with an official app, the ChatGPT comparison and Claude comparison say where each is the better fit.

Numbers on a page are easy to misread. Here is how the daily allowances line up with real work.

Premium-model messages: 10 a day

A message is one prompt you send to a premium model, such as Claude Sonnet 5.5 or Gemini 3.1 Pro. Ten is enough for a focused task: drafting and revising one document, or working through a hard problem. Everyday lookups and quick rewrites can go to fast models, which do not use the 10.

Web searches: 5 a day

Each search returns an answer with cited sources. Five covers a handful of fact-checks. For one broad question, a single deep research run (1 a day on Free) is the better spend.

Images, translations and dictation

Three images a day suits occasional use. Three full-page translations is enough for the few foreign-language pages you read in a day; selecting a paragraph to rewrite or translate is not the same thing as a full-page translation. Five voice drafts cover short bursts of dictation, where your browser supports speech recognition.

When you run out

The chat does not stop. After the premium messages are used, it continues on the provider's fast model, and counts reset the next day.

Free tiers change often, so this is what each vendor's own page or official Chrome Web Store listing said as of November 2026, in plain terms. Follow the links to read the current wording.

The figures are not like for like: "Pro chat", "premium message" and "web session message" are each defined by their own vendor. The only reliable test is to use each on your own tasks. Merlin's listing does not state free limits, so see the Merlin comparison for what we could verify.

Chrome, Brave, Opera, Arc and Vivaldi

These Chromium browsers all install the Chrome Web Store build. Open the listing from the download page or the Chrome page, click Add to Chrome (or the equivalent in your browser), then confirm. Then click the puzzle-piece icon and pin Copilotly so it stays visible. See Google's guide to installing and managing extensions.

Edge and Firefox

Edge and Firefox each have their own store listing, linked from the download page: Edge and Firefox.

Safari

There is no Safari build yet. Use Chrome, Edge or Firefox for the extension, or the iOS app or web app on Apple devices.

Phone and web

The iOS and Android apps and the web app at app.copilotly.com use the same account and work on the free plan.

The free plan is a limited version of the same product, not a trial that expires. You pay nothing and give no card. The limits are the daily allowances above, and Pro is how Copilotly makes money.

What you should still do is treat anything you type as sent to an AI model: the model provider processes it to produce an answer. Do not paste passwords, card numbers or anything confidential. Incognito chats are available if you do not want a conversation kept in your history. See memory and personalization for how memory works.
