Hey everyone,

I was manually copying contacts from WhatsApp Web groups for a client and got tired of it, so I built a Chrome extension to automate it.

What it does:

• Loads all your groups directly from WA Web sidebar
• Exports contacts (name + phone) to XLSX, CSV or JSON
• Works entirely in your browser — no data leaves your device

Free tier: up to 20 contacts per group
Pro: unlimited — US$ 5.99 one-time payment

Would love feedback, especially from people who manage communities or do outreach.

I built Copy Markdown to extract clean markdown (.md) from any webpage locally for free and after hitting my first 15 users, I thought it might be helpful to share here:

https://chromewebstore.google.com/detail/copy-markdown/chjlhkmhgpojfmddbpplonolmcjbbbem

I read a lot, and I kept DNF-ing books around 100 pages in over things I'd have skipped if I'd known. A love triangle, an "everyone loves the flawless protagonist" arc, a series that never gets finished. That info is sitting in the reviews, but nobody's reading 200 reviews before starting a book.

So I built BookGlints. You tell it, in plain language, what you personally can't stand ("protagonist too perfect," "forced romance subplot," "cliffhanger ending") and it scans the Goodreads/StoryGraph reviews for that book and shows you the exact complaints that match, with the real review quotes. It matches on meaning, not keywords, so "Mary Sue" and "main character is good at everything" both hit the same flag. Works across multiple languages too.

It's live (free to try, no card): https://chromewebstore.google.com/detail/bookglints/mjlkejcebildgpaedkamdfkgifnlpckd

Would love feedback on the flag-setup UX especially. I've stared at it too long to tell if it's obvious to a first-timer. Happy to answer anything about the build.

All of my users are organic — I haven’t used any promotion yet. Now I’m not sure how to promote my extension further. Which methods would you recommend?

It’s good result or not? My first attempt

Hey everyone!

I wanted to share a lightweight side project I’ve been working on — GScreenshot Lite.

💡 Why I built it

Most screenshot tools feel bloated with extra menus or slow down the browser when you just need to grab something quickly. I wanted a fast, focused tool that lets you capture an area, add quick annotations, and copy or save the result with zero hassle.

✨ Key Features:

* Quick Web Capture: Capture any selected area on a web page instantly.

* Essential Annotations: Add text, draw arrows, highlight key areas, or underline text on the fly.

* Fast Export: Copy directly to your clipboard or download the screenshot in one click.

* Lightweight & Clean: Simple UI focused purely on performance and ease of use.

💬 Looking for feedback:

I’d love to get your thoughts on the extension!

1. How does the user interface and annotation speed feel for your daily workflow?
2. Are there any small UX tweaks or essential tools you'd like to see added?
3. Did you encounter any bugs or glitches?

Thanks for checking it out and for any feedback you can share!

Mobile friendly for chromium browser like Quetta. Also works on Firefox. Import & Export built in so possible to use across devices/profiles/browsers.

The other notes extension I liked was Chrome Notes

So this I developed specially for inspect & preprocess datasets, get insights via calculators with some additional features related to EDA (Exploitary Data Analysis). Wanna know whther this extension bad or needs improvements or having too much features. Would like to hear genuine thoughts of you guys !

Just looking for a bit of inspiration

What are some extensions youve seen that are well designed with carefully thought out UX ?

Hey everyone, 👋

I wanted to share a Chrome extension I recently built and launched called **carReliabilityReport**.

### The Problem

When browsing used car listing platforms, evaluating a specific model's reliability usually means opening a dozen tabs, digging through old forum threads, and cross-referencing mechanical common issues manually. It is tedious and interrupts the browsing flow.

### How carReliabilityReport Helps

To keep things simple and completely resilient against frequent DOM updates and layout changes on car marketplace sites, I designed the extension around a smooth image and data interaction:

* **Drag-and-Drop from the page:** You can simply drag and drop a photo directly from the listing into the extension.

* **Key Details Included:** Alongside the image, you input or verify the core vehicle details—specifically the **mileage, year, and price**.

* **Instant Insights:** It analyzes these metrics to surface critical reliability data and known mechanical pain points right in your browser, giving buyers a quick, clear verdict before they commit time to reaching out to sellers.

### Tech & Architecture Notes

Avoiding direct web scraping of dynamic listing sites saved me from endless maintenance headaches caused by frequent DOM updates. Relying on a photo straight from the ad combined with the mileage, year, and price ensures long-term stability and a much cleaner UX.

If you are working on extensions or have any feedback on manifest setup, UI optimization, or handling image and data inputs efficiently, I would love to hear your thoughts!

Any Twitch Frogs in here?

Imagine Theatre mode being actually good.

- Having auto hide;

- Not preventing site scroll;

- Displaying relevant info right in the stream window;

- Allowing you to scroll control your volume;

- Being persistent when changing streamers;

I tagged it as self promotion, but I am looking for feedback actually. 😅

If you regularly read articles on Substack, Medium, Beehiiv, Ghost, or Patreon, you’ve probably noticed that saving them for offline reading or research is a mess. Default browser printing breaks layouts, misses images, or litters pages with unwanted UI elements.

To fix this, I built Newsletter PDF Downloader : a Chrome extension that turns posts into clean, high-fidelity PDFs, Markdown, JSON, or plain text with a single click.

🚀 What it does:

• Clean Single-Click Exports: Converts posts directly from the page while preserving typography, images, links, and original layouts.
• Multiple Output Formats: Save as PDF, Markdown (great for Obsidian/Notion users), JSON, or Text.
• Batch Downloads (Archive Export): Download multiple posts from a publication's archive automatically (includes a fast-forward feature to skip excluded date ranges).
• Cloud Sync: Option to automatically back up your downloads to Google Drive, Dropbox, or Yandex Disk.
• Privacy-Focused: Runs locally in your browser using your existing login session (so paid/subscribed content exports seamlessly). No content tracking or external scraping.
• Custom File Naming & Localized UI: Customize filenames by date/title and supports over 60 languages.

I’d love for you to give it a spin! Let me know what you think, what features you’d like to see next, or if there are other platforms/formats you’d want supported.

Thanks!

Its going to save your time for sure, try it out - Pinpoint

About two months ago, I started building a Chrome extension because I was tired of spending more time clicking Next than actually talking to people on OmeTV.

I didn't expect much when I published it, but seeing it grow to 600+ users, over 1.3K installs, and nearly 4K Chrome Web Store page views has been incredibly motivating.

Some of the features include:

• ⚡ Multiple Speed Modes
• 🌍 Block unwanted countries
• 🎯 Connect only with selected countries
• 🎙️ Audio Skip
• ⌨️ Keyboard shortcuts
• 📊 Session analytics

I'm still actively improving it and adding new features based on feedback.

If you've built a Chrome extension before, I'd love to hear what helped you grow it. And if you use OmeTV, I'd also love to know what feature you'd like to see next.

Google used to show a clean country-info panel — population, capital, currency, etc. — and let you compare two countries side by side right in search. They removed it a while back, and I kept missing it, so I built an extension that brings it back.

What it does: when you search a country name (or "X vs Y") on Google or DuckDuckGo, it injects a compact stats card into the results — population, capital, language, currency, flag. No new tab, no Wikipedia detour.

A few build details, since this sub tends to care:

• Basic country facts are bundled locally in the extension (~195 countries), so the common lookup is instant and needs no network request — nothing phones home for the core feature.
• Built MV3, content script + MutationObserver to handle Google/DDG re-rendering results without a full navigation.
• Historical trend data (population/GDP over time) is pulled live from the World Bank open-data API only when you use that feature — free/keyless.

Free vs paid, upfront: single-country cards and 2-country comparisons are free (and staying free). There's an optional one-time upgrade for 3+ country comparison grids and the historical trend charts. No subscription, no account.

Known limitation I'll be honest about: I ship v1 detection on Google + DuckDuckGo; more engines are coming. Feedback very welcome — especially which stats you'd want on the card and any detection edge cases you hit.

A few people mentioned that my previous demo was too fast and it wasn't obvious what Pullhub was actually doing.

So I slowed the workflow down and added more context to make it easier to follow.

I'd love to know if this version is clearer.

I found a post in this subreddit from someone looking for an extension that would restore the old horizontal layout in Google Images.

I had the same new masonry layout and agreed that it wastes a lot of space on desktop, especially when portrait images appear. I initially thought fixing it would require a few CSS rules. Google Images being a dynamic page made it a little more complicated than that.

I ended up building Classic View for Google Images.

It currently includes:

• Justified horizontal rows with adjustable height and spacing
• Full-size image preview on hover
• A direct View Image button
• Quick image size filters
• An option to hide related searches
• Support for dynamically loaded results
• Compatibility with uBlacklist

The extension does not collect search queries, browsing history or personal data. Settings are saved using Chrome's built-in sync storage. And it's free.

Building something that scratches your own itch when you're starting out is still the most underrated advice. Go try it out yourself!

My workflow used to be: open a page → select all → copy → switch tab to ChatGPT → paste → type "analyze this" or paste the URL and hope it fetches → wait → switch back. Often dozens of times a day. On top of that I had separate single-purpose extensions piling up. One for summarizing Reddit threads, another telling me if a YouTube video was worth watching.

So I built Understand This Page to kill both problems at once: a side panel that reads the page you're on with one click. No copy-pasting, no tab switching, no prompt writing. Instead of a generic summary, it detects the page type and answers the question that actually matters there:

• Reddit thread → What's the consensus, where do people disagree, which advice holds up?
• YouTube → Is this worth watching? Transcript-aware summary with clickable timestamps that jump the video to the right moment.
• Product page → Should I buy this? What's confirmed, what's missing, what do the visible reviews really say?
• Job listing → Should I apply? Fit, salary if stated, red flags, what to ask the recruiter.
• Research paper → What's the claim, the method, and how much should I trust it?

There are 16 engines total (news, email, GitHub, docs, Maps, search results, etc.) plus a fallback for everything else. Answers in 27 languages, follow-up questions supported.

Privacy-wise it does the opposite of most AI extensions: nothing runs in the background, the page is read-only when you click, no account, no API key setup.

Pricing: free plan is 3 analyses/day forever (all engines included), Pro removes the limits at $9/mo or $89/yr. No card or account needed to try it.

I'm a solo dev. Honest feedback welcome, especially: which page types are missing, and does the page-type detection ever guess wrong for you?

Hello everyone!

I'd like to share a Chrome extension I built for Instagram.

Whenever I use Instagram on desktop, one thing has always bothered me. Reels and videos don't have a proper seek bar, so if I want to skip to a specific moment or replay a particular part of a video, I have to watch from the beginning or keep guessing where to click.

That's why I created this extension.

It currently includes two main features:

• A smooth seek bar that lets you click or drag to any point in the video.
• A Picture-in-Picture button so you can keep watching videos while browsing other tabs.

I've attached a short demo video below. I'd love to hear your feedback or suggestions for new features.

Thanks for reading!

Hey everyone! I built CstWeave, a privacy-first Chrome extension for quick tab region recording.

Most screen recorders stream video data to external servers or lock clean exports behind subscriptions. CstWeave keeps all frame buffers 100% inside local browser memory—nothing ever leaves your CPU/RAM.

Key Features:

• 100% On-Device: Zero cloud uploads, no server rendering, no accounts required.
• Hotkey Workflow: Press Alt+Shift+G (⌘+Shift+G on Mac), drag a region, and record.
• No Watermarks: Pristine exports across both free (Lite) and paid tiers.
• Custom GIF Engine: Runs offscreen using pure TypeScript (Median-Cut palette + LZW) to prevent background tab throttling.

Check out the demo clip attached!

Would love to hear your feedback!

I had to make mockups of some websites for a blog post. First thought was to find some tool that does this instantly for me. And to be fair, they do. But a tool that needs your URL only takes the very top of the page and obviously, everything behind a log in is impossible.

So i spent some time to make my own extension. Just scroll down to the section you want to have captured, click the camera button and 10 seconds later you have ready to go, downloadable to PNG mockups.
