Monica alternative: Copilotly compared

As of November 2026, Monica covers far more surface area than Copilotly. The facts below are from its Chrome Web Store listing and its home page (monica.im).

More platforms

Monica's home page lists a web app, a browser extension for Chrome and Edge, desktop apps for Windows and Mac, Android and iOS apps, and Monica Code, a coding assistant for VS Code and JetBrains IDEs. Copilotly has browser extensions, a web app and iOS and Android apps. It has no desktop app and no IDE plugin.

More built-in features

The Chrome listing names Monica Agent, Browser Operator, Deep Research and Slides Generation, plus a prompt library, voice input, an "AI Memo" knowledge base, and image and video creation (it names Nano Banana Pro for images and Sora 2 for video). The home page also lists a template library of over 80 options, bots, and PDF tools including PDF translation and a resume checker. Copilotly generates spreadsheets, documents and slides as downloadable files and has image generation, but does not list video generation or a browser operator.

Scale

The listing shows about 3,000,000 users and a 4.8 rating from 32.4K ratings, marked Featured, at version 9.0.24 updated November 2, 2026. Those are Monica's own figures from its listing.

If you want one assistant for coding, documents, video and chat on every device, Monica's range is the bigger one and deserves a serious look.

More browsers, one build

Copilotly installs in Chrome, Edge, Firefox, Brave and Opera (Brave and Opera use the Chrome Web Store build). Monica's listing and home page name Chrome and Edge for the extension.

Rewrite anywhere with a diff

Rewrite anywhere works on selected text in any page with tone and length pickers, a word-level diff, versions and undo. Monica lists writing tools; we have not verified how they show changes.

Deep research and cited search

Deep research shows a live research plan, and web search cites its sources. Monica lists Deep Research as well, so this is parity.

Your own API key, never metered

Copilotly lets you use your own key, and requests on it are never metered. Monica's listing and home page do not mention a bring-your-own-key option.

Memory and My Voice

Copilotly remembers preferences and learns your writing style with My Voice. Monica lists an "AI Memo" knowledge base, which is a related but different idea.

Both do bilingual or side-by-side page translation, web search, YouTube summaries and chat with PDF, so those are not differentiators.

Monica's listing says it offers "limited use for free" and a Premium Plan for unlimited access, and marks in-app purchases. Its pricing page returned only its title to our fetcher in November 2026, so we do not quote a price.

Copilotly Free gives you fast models within a token allowance, plus per day: 10 premium-model messages, 5 web searches, 3 images, 1 deep research run, 3 full-page translations and 5 voice drafts. Copilotly Pro is $6.99/week, $19.99/month or $149.99/year, with a 7-day free trial for first-time subscribers. See pricing and the free plan page.

When you compare, check how each treats the strongest models on the free tier, since that is where most limits bite.

Choose Monica if

you want desktop apps, a coding assistant, an agent or browser operator, slide and video generation, or its template and bot library. It is the more complete suite.

Choose Copilotly if

you use Firefox, Brave or Opera, want in-place rewriting with a diff, want to bring your own key, or just want a simpler free sidebar. Also see the Sider comparison and MaxAI, or which AI tool fits your job.

Feature lists tell you little. A short test on your own work tells you a lot, and costs nothing because both have free tiers.

A one-week test

1. Day 1: summarize the same YouTube video in both and check the summary against the video.
2. Day 2: ask a question about the same PDF in both. Check that each answer points to the right section.
3. Day 3: translate the same foreign-language page in both and read the result against the original.
4. Day 4: rewrite the same three emails in both, at the same tone.
5. Day 5: do a task you could only do in one (an IDE task for Monica, a rewrite with a diff for Copilotly) and decide how much it matters.

What to record

Write down how many times you hit a free limit, how many answers you had to correct, and which interface you opened without thinking. The last one is usually the real answer.

Removing an extension from your browser does not delete your Monica account or chats; that is managed in Monica itself, so use its own account controls if you want data removed. Monica's Chrome listing discloses what it handles, including personal communications and user activity, and says it does not sell data outside approved use cases. Read the listing's privacy section before deciding.

Copilotly sends the text you ask about to the AI model that answers. Do not paste passwords or card numbers into any assistant. For how Copilotly handles incognito chats, memory and sharing, see memory and personalization.

1. List the Monica features you used last week. Anything on the "more platforms" list above stays with Monica.
2. Install Copilotly from the download page and sign in.
3. Use a different shortcut. Monica's listing says Cmd/Ctrl+M summons it, and Copilotly uses Alt+C. If you want Copilotly on the same key, change it at chrome://extensions/shortcuts after removing Monica.
4. Move PDF and YouTube habits. Open a PDF in the browser or a YouTube page and ask Copilotly directly. See chat with PDF and YouTube summaries.
5. Re-enter instructions. There is no import from Monica; paste your instructions into Copilotly's custom instructions.
6. Remove Monica from the three-dot menu, Extensions, Manage extensions, Remove, once you are sure.
