The internet has changed. With the explosion of AI-generated content, automated workflows, and “answer engines,” navigating the web requires a new set of tools. Here are ten essential browser extensions to help you stay productive, verified, and efficient in the post-AI era.
1 Perplexity AI
Traditional search is being replaced by “answer engines.” The Perplexity extension allows you to skip the list of blue links. With a single click, you can ask questions about the page you are currently on or search the entire web for a cited, summarized answer. It’s the ultimate tool for cutting through SEO-bloated articles.
2 Monica
Monica acts as an AI sidekick that lives in your sidebar. It integrates GPT-4, Claude 3, and Gemini, allowing you to process any text on any website. Whether you need to summarize a PDF, translate complex technical jargon, or compose a formal email directly within your browser, Monica handles it all without switching tabs.
Video Summarization
3 Eightify
In the post-AI web, video content is more abundant than ever. Eightify uses AI to summarize YouTube videos instantly. It provides key insights and timestamps, allowing you to decide if a 30-minute video is worth your time before you even click play. It is essential for rapid learning and research.
Reading & Fact-Checking
4 Wiseone
With AI making it easier to generate misinformation, Wiseone is a researcher’s best friend. It helps you master your online reading by cross-referencing information, simplifying complex terms, and providing a “Check Facts” feature that pulls data from multiple reliable sources to verify claims in real-time.
5 Grammarly
Grammarly has evolved far beyond a spellchecker. Its new generative AI features help you rewrite sentences for specific tones, brainstorm ideas, and even draft replies based on the context of your email threads. It ensures your human-driven content remains polished in a world of automated text.
Verification
6 Originality.ai Lite
As the web becomes flooded with synthetic content, knowing what is human-written is increasingly important. This extension allows you to scan text on a webpage to determine the likelihood that it was generated by an AI. It’s a vital tool for editors, students, and skeptical readers.
Workflow Automation
7 Merlin
Merlin offers a “magic” CMD+M (or Ctrl+M) shortcut that brings up an AI prompt on any website. Its standout feature is the ability to summarize LinkedIn posts, automate Twitter/X replies, and even write complex Excel formulas directly in your Google Sheets web interface.
8 Glasp: Social Web Highlighter
Glasp allows you to highlight and tag content across the web, but its AI “Digital Twin” feature is what makes it post-AI ready. It uses your highlights to learn your interests, allowing you to query your own curated knowledge base using AI to find connections between things you’ve read months ago.
9 Fireflies.ai
The post-AI web isn’t just about reading; it’s about the transition from meetings to data. The Fireflies extension integrates with Google Meet and Zoom (web version) to record, transcribe, and summarize your meetings. It turns your conversations into searchable knowledge assets instantly.
10 Consensus
Tired of AI hallucinations? Consensus is a search engine that uses AI to find answers solely from peer-reviewed scientific research. The extension allows you to highlight any “scientific claim” you find on the web and see if the actual research supports or refutes it. It is the ultimate antidote to AI-driven “fake news.”
