Monica.im Review: Is It Still Worth Using in 2025?

If you’ve spent any time around AI writing tools over the past year or so, you’ve probably come across Monica.im, a platform that promises to be your “all-in-one” AI assistant. 

Monica.im has definitely built a reputation for being one of the most convenient AI tools out there. 

But as 2025 draws to a close, it’s clear that the competition is only getting better and better… with tools like ChatGPT’s new desktop app, Perplexity, and advanced content writing platforms like Ikke påvisbar AI setting a much higher standard for quality and (most importantly for us), accuracy. 

So the real question is: Is Monica.im still relevant in 2025? Or has it been outpaced by newer, smarter AI tools? 

In this honest Monica.im review, we’re breaking down how the platform works, what it costs, and how accurate its AI detection tool virkelig is when tested side-by-side with our own AI detector.

Det viktigste å ta med seg

• Monica.im is a browser-based AI assistant with a handful of extra AI tools on its website.

• Notable features include its AI summarizer, AI writer, and chat assistant. 

• Based on our experience, the free version of most tools is very limited. So to get the most out of the platform, you’ll want to pay for the Pro plan. 

• We also tested Monica.im’s free AI Detector, which gave vague results without clear accuracy scores or percentages.

What Is Monica.im?

Monica.im or just “Monica” is a browser-based AI assistant designed to integrate into your workflow. 

So instead of switching between separate AI platforms or opening ChatGPT in another tab, Monica lives right inside your browser (typically installed as a Chrome or Edge extension). 

Once installed, you’ll have a small pop-up AI assistant, ready to help you:

• Summarize web pages, PDFs, or YouTube videos.
• Write, rewrite, and “humanize” AI text.
• Translate writing across multiple languages.
• Generate ideas, outlines, or responses to text prompts.
• Ask questions about the websites and content you’re viewing.

In addition to its browser extension, Monica.im also offers dozens of AI tools you can use directly on the Monica.im website (without having to install the Chrome extension).

This includes tools like an AI math solver, an AI logo generator, and a basic AI detector.  

Hvordan fungerer det?

Monica.im can work in a few different ways. 

As a browser extension, it sits right at the top of your browser and acts like a built-in ChatGPT on every website you visit. 

To download the extension: Head to the Monica.im website and click “Add to Chrome” or “Add to Edge”. 

If you don’t want to install the Chrome extension, you can also use Monica’s suite of AI tools directly on the Monica.im website. 

To use the website tools: Head to the Monica.im website, click “Products”, and you’ll find a list of AI tools categorized by: Image Tools, PDF Tools, Writing Tools, and Summary Tools. 

And in addition to the browser extension and online tools, Monica.im also offers mobile and desktop apps for Android, iOS, Windows, and Mac. 

To download a mobile or desktop app: Head to the Monica.im website, click “Products”, and you’ll find options for both mobile apps and desktop apps. 

How Much Does Monica.im Cost?

Monica.im offers a “freemium” pricing model. This means you can start using most of the tools for free, but you’ll definitely run into some limitations. 

With a free plan, you’ll have access to most of Monica’s basic AI functions, including the Chrome extension, web chat, summarization, and translation tools.

However, you’ll be capped on the number of queries you can send per day. And, you won’t have access to the more advanced GPT models. 

Here’s a general breakdown of what you can expect on the Free, Pro, and Unlimited plans. 

Monica.im Pricing
Plan	Pris	Viktige funksjoner
Gratis plan	$0	Basic AI chat, summarizer, translator, and Chrome extension access. Limited daily messages and GPT-4o responses.
Pro Plan	Around $9.90/month	Higher daily limits, faster response times, premium writing templates, and access to advanced AI models (like GPT-5 and Claude 4.5).
Ubegrenset plan	Around $24.90/month	Even higher daily limits, plus unlimited access to basic and advanced models.

Slik tester vi AI-verktøy

Before recommending (or rejecting) any AI tool, we alltid test the platforms for ourselves. And because we specialize in AI detection, we wanted to focus on Monica’s AI Detector tool. 

So to check for accuracy, we tested two short writing samples (each around 100 words). 

Writing Samples
100% AI-Generated Sample (Written by Chat GPT)	Human-Edited AI Sample
Gen Z isn’t just changing how we work and communicate — we’re redefining how the world travels. With a phone full of apps, an eye for budget-friendly adventures, and a passion for experiences over possessions, Gen Z travelers are rewriting the rules of exploration. Forget the glossy travel brochures — this generation finds hidden flight deals on TikTok, books eco-friendly stays through niche platforms, and turns weekend getaways into full-blown digital detoxes (or content opportunities). Whether you’re planning your first solo trip, trying to stretch your student budget across Europe, or just want to travel like a pro without breaking the bank, these Gen Z–approved travel hacks will help you save money, skip stress, and see more of the world — your way.	Gen Z has redefined the way we work, the way we communicate, and now? We’re redefining how the world travels.  With a phone chock full of apps and keen eye for a budget-friendly adventure, Gen Z travelers have officially rewritten the rules of exploration.  So whether you’re planning your first solo trip or just trying to figure out how to make your budget stretch across Europe, these Gen Z-approved travel hacks will help you save money, skip the stress, and see the parts of the world you’ve always wanted to see.

We then ran each sample through Monica.im’s AI Detector and our own Undetectable AI Detector (which is proven to be one of the most accurate AI detection tools available). 

Resultater

Here are the results of these quick tests: 

Monica.im vs Undetectable AI: AI Detectors Compared
	100% AI Sample		AI Edited Sample
Monica.im	“Seems” to be AI-generated		“Seems” to be AI-generated
Ikke påvisbar AI	99% AI Sannsynlighet		84% AI Probability

For both samples, Monica.im gave the same vague verdict of: “Seems to be AI-generated."

That result didn’t change whether the content was 100% AI-written or human-edited, which makes us wary of the tool’s overall accuracy.

Monica.im also did not display a clear probability score or sentence-level breakdown in its free version. To see any detailed analytics, you have to upgrade to a paid plan. 

I motsetning til dette, Uoppdagelig AI-detektor delivered a more precise breakdown of what was and wasn’t likely to be AI. 

The 100% AI sample was correctly identified as 99% AI-generated.

And then the human-edited sample came back at 84% probability, showing that the detector is sensitive enough to detect even minor human involvement in AI-generated text.

You can also run the same samples through our AI-sjekker to verify whether tool-generated content is truly original.

It benchmarks AI vs human traits, returns clear probability scores with sentence-level highlights, and shows exactly what still needs revision.

Monica.im vs Undetectable AI

It’s clear that Monica.im and Undetectable AI are two completely different platforms with different strengths, weaknesses, and purposes.

Here’s how the two platforms compare. 

Monica.im vs Undetectable AI Compared
	Monica.im	Ikke påvisbar AI
Primært formål	Browser-based AI assistant for quick tasks and very light writing help.	Advanced AI detection, rewriting, and humanization platform for professional content creation.
AI-detektor	Basic verdict (“Seems to be AI-generated”), no probability score or sentence breakdown.	Industry-leading AI detection accuracy with detailed AI probability maps and sentence-level analysis.
Humanization Tools	Basic rewriter and tone adjuster.	Dedikert AI Paraphraser og Stealth Writer tools that rewrite text to sound naturally human and pass AI detectors.
Brukervennlighet	Extremely beginner-friendly with simple right-click and sidebar functions.	Simple dashboard designed for editors, educators, and SEO writers.
Best for	Students, researchers, and casual users.	Professionals, publishers, and agencies that rely on accurate, undetectable writing.
Priser	Freemium model, limited access to advanced GPT models and better features.	Free AI Detector + affordable premium tools for rewriting and detection at scale.

Avsluttende tanker

So, is Monica.im still worth using in 2025? 

If you need a simple AI tool for your browser, Monica.im provides a decent service (if you’re willing to pay for the pro plan). 

However, if you need more advanced AI functionalities, like accurate AI detection with detailed analysis, Monica alone probably won’t be enough. 

Based on our testing, Monica’s AI Detector was too vague to be useful. It gave identical “Seems to be AI-generated” results across both test samples. And it did not show clear probability scores, which is standard across most free AI detection tools (including our own free AI Detektor). 

Although we didn’t test the paid version, we’re left feeling a bit skeptical as to whether it can offer the level of precision that professional writers, marketers, and academics need.

For a more reliable and precise AI detection experience, try Udetekterbar AI.

It offers advanced detection accuracy, humanization features, and detailed analysis to ensure your content stays authentic and professional.
