ChatGPT is powerful out of the box, but the right browser extensions can take it further—better prompts, cleaner output, faster workflows.
I've tested dozens of ChatGPT extensions. Most are bloated, redundant, or abandoned. Here are the 8 that actually earned a spot in my browser, with honest assessments of what each does well and where they fall short.
Quick Summary
- Best for prompts: AIPRM for ChatGPT
- Best for search integration: ChatGPT for Google
- Best for power users: Superpower ChatGPT
- Best for clean output: DeGPT
- Best for emails: ChatGPT Writer
- Best for browsing: Merlin or Monica
- Best for YouTube: YouTube Summary with ChatGPT
AIPRM for ChatGPT
Prompt templates and community library
AIPRM adds a prompt library directly into ChatGPT's interface. You get thousands of community-created prompts organised by category—SEO, marketing, coding, writing, and more.
What it does well:
- Huge library of tested prompts you can use immediately
- One-click prompt insertion
- Save and organise your own prompts
- Active community constantly adding new prompts
Honest downsides:
- The interface can feel cluttered—lots of options compete for attention
- Quality of community prompts varies wildly
- Premium features require a subscription
- Can slow down ChatGPT's interface on older machines
Best for: People who want prompt inspiration and templates. Especially useful if you're new to prompt engineering.
ChatGPT for Google
AI answers alongside search results
This extension shows ChatGPT's response in a sidebar when you search on Google (or DuckDuckGo, Bing, etc.). You get traditional search results plus an AI take.
What it does well:
- Seamless integration—appears automatically on searches
- Works with multiple search engines
- Quick way to get AI context without opening ChatGPT
- Clean, minimal interface
Honest downsides:
- Less useful now that Google has its own AI overviews
- Requires you to stay logged into ChatGPT
- Responses can be slower than native Google AI
- Adds visual noise to search results pages
Best for: People who want a second opinion alongside traditional search, or prefer ChatGPT's responses over Google's AI.
Superpower ChatGPT
Advanced features for power users
Superpower ChatGPT adds features that ChatGPT should probably have built-in: chat history search, export options, custom instructions per chat, and more.
What it does well:
- Search through all your chat history
- Export chats to markdown, PDF, or JSON
- Pin important conversations
- Word/character count
- Auto-continue when responses get cut off
Honest downsides:
- Feature-heavy—takes time to learn what everything does
- Some features duplicate what ChatGPT now offers natively
- Can conflict with other ChatGPT extensions
- Occasional bugs after ChatGPT interface updates
Best for: Heavy ChatGPT users who need to search, export, or organise conversations. Researchers and writers will appreciate the history features.
DeGPT - Clean AI Text
Format and clean ChatGPT output for professional use
DeGPT solves a specific but common problem: ChatGPT output looks fine in the chat window, but when you paste it into Word, Outlook, Notion, or Google Docs, the formatting breaks. DeGPT cleans text so it pastes correctly.
What it does well:
- One-click cleaning directly in ChatGPT
- Fixes bullets, headings, and spacing for different destinations
- Removes "AI tells"—phrases that scream "this was written by ChatGPT"
- Strips markdown when you need plain text
- Optional PII removal (emails, phone numbers)
- Works with different destination profiles (Word, email, plain text)
Honest downsides:
- Focused specifically on text cleaning—doesn't add prompts or other features
- Only useful if you actually copy ChatGPT content to other apps
- Newer extension with a smaller user base than established players
Best for: Anyone who regularly copies ChatGPT output into documents, emails, or notes. Particularly useful for business users sending AI-assisted emails.
ChatGPT Writer
AI email and message writing
ChatGPT Writer focuses on one thing: helping you write emails and messages. It integrates with Gmail and other platforms to draft responses or new messages using AI.
What it does well:
- Works directly in Gmail—no copy-paste needed
- Can read the email you're replying to for context
- Simple interface focused on the task
- Fast for quick replies
Honest downsides:
- Limited to email/messages—not a general ChatGPT enhancer
- The AI tone can be generic without careful prompting
- Results still often need editing before sending
- Less control over output compared to using ChatGPT directly
Best for: People who write lots of emails and want a quick drafting assistant without leaving Gmail.
Merlin
AI on any website
Merlin brings AI assistance to any website via a keyboard shortcut. Highlight text, press the shortcut, and get summaries, explanations, or rewrites without switching tabs.
What it does well:
- Works everywhere—any website, any text
- Fast keyboard shortcut access
- Multiple AI models available
- Good for quick questions while browsing
Honest downsides:
- Free tier has daily limits
- Can feel intrusive if you accidentally trigger it
- Premium features get expensive
- Overlaps with similar tools like Monica
Best for: People who want quick AI access across the web without opening ChatGPT.
Monica
AI copilot sidebar
Monica is a sidebar AI assistant that can chat, summarize pages, help with writing, and more. It's like having ChatGPT available in a side panel on any website.
What it does well:
- Persistent sidebar doesn't interrupt your workflow
- Can read and summarize the current page
- Writing assistance with multiple tones
- Clean, polished interface
Honest downsides:
- Free tier is quite limited
- Subscription required for regular use
- Sidebar takes up screen space
- Feature overlap with native ChatGPT sidebar (if you have Plus)
Best for: People who want an always-available AI assistant while browsing, and don't mind a subscription.
YouTube Summary with ChatGPT
AI video summaries
This extension adds a "Summarize" button to YouTube videos. Click it, and ChatGPT generates a summary of the video content based on the transcript.
What it does well:
- Save time on long videos—get the key points in seconds
- View and copy video transcripts
- Works with most English videos
- Simple, single-purpose tool
Honest downsides:
- Only works if the video has a transcript/captions
- Summary quality depends on transcript accuracy
- Doesn't work well with highly visual content
- Opens ChatGPT in a new tab (not inline)
Best for: Researchers, students, or anyone who watches educational/informational YouTube content and wants quick summaries.
How to choose the right extensions
Don't install all of these. Pick based on your actual workflow:
If you mainly use ChatGPT for work emails and documents:
Start with DeGPT (for clean output) and optionally ChatGPT Writer (for Gmail).
If you're learning prompt engineering:
AIPRM is your best starting point for prompt templates and ideas.
If you want AI help while browsing:
Choose either Merlin or Monica (not both—they overlap significantly).
If you're a ChatGPT power user:
Superpower ChatGPT adds the most missing features for heavy users.
A word of caution
Browser extensions have access to your browsing data. Before installing any extension:
- Check the permissions it requests
- Look at user reviews and ratings
- Consider whether you actually need the features
- Be cautious with extensions that require accounts or subscriptions
All extensions in this list are established tools with significant user bases, but you should still do your own due diligence.
Final thoughts
The best ChatGPT setup is one that fits your workflow. For most people, 1-2 extensions is plenty. Start simple, add more only if you find yourself needing specific features.
If you're copying ChatGPT content into documents or emails daily (like most business users), DeGPT solves a real friction point. If you need prompt inspiration, try AIPRM. If you want AI everywhere while browsing, pick Merlin or Monica.
