I've been building this screenshot extension for a while, and honestly I'm starting to question whether it's actually useful beyond being a nice side project.

A few hundred people are using it, reviews have been pretty positive, and people seem to like the workflow. But at the same time, it's still just another screenshot extension. There are already a ton of them.

I built a lightweight browser extension called Social Monitor. You can use it to pull posts from specific subreddits, users, e.t.c. I'll add other sites, but its still pretty useful. Pls give me ur honest opinions.

Hi everyone,

I’m currently working on a Chrome extension, and I’ve run into a UI/UX design problem.

There is already an extension that has a UI very similar to what I originally had in mind. It uses a compact floating toolbar/tool-style interface rather than a traditional extension popup.

I like this approach because it fits the workflow of the tool really well, so I don’t want to completely change the interaction model just for the sake of being different.

However, I also don’t want my extension to feel like a clone of an existing product.

For those who have built browser extensions before:

• How similar can the UI/UX of two extensions be before it starts feeling like a copy?
• Would you keep the same general interaction model if it provides a better UX for the task?
• Should I focus more on differentiating the visual design, or the actual workflow and functionality?
• What are some good ways to make a tool feel original when the basic UI pattern is already established?
• At what point would you consider an extension's UI to be "too similar"?

For example, I'm considering keeping the general floating toolbar concept, but changing the tool organization, interactions, color selection workflow, and overall visual hierarchy.

I'd especially appreciate feedback from people who have designed or developed Chrome/Firefox extensions.

Thanks!

Hi everyone,

I recently built a small Chrome extension called Simple WebP Screenshot.

The idea was pretty simple: I wanted a screenshot tool that stays lightweight, gives me the basic editing tools I actually use, and saves the final image directly as WebP instead of producing unnecessarily large PNG files.

It currently supports:

Visible area screenshots

Full-page screenshots

Selecting a specific area

Crop

Blur

Highlighting

Drawing

Rectangles and circles

Arrows and text

Different colors and line thicknesses

Undo and reset

Copy to clipboard

Custom file names

Automatic .webp extension

Adjustable WebP quality, with 85% as the default

Everything is processed locally in the browser. There’s no image upload or external processing involved.

I originally built it for my own workflow, especially when preparing screenshots for websites and content, but after using it for a while I decided to publish it publicly on the Chrome Web Store.

It’s currently at v1.2.7.

I’d really appreciate feedback, especially from people who regularly take screenshots for documentation, blogging, development, or support work.

If there’s one small feature you think a screenshot extension should absolutely have, I’d be interested to hear it.

Simple WebP Screenshot – available now on the Chrome Web Store.

If you use Instagram on your browser, you know how frustrating it is to find a specific old post or filter through a busy profile — there's no search, no sort, nothing. I built Grid Insights to fix that.

It's a lightweight Chrome extension that adds the tools Instagram's web app is missing:

Key Features:

• Search & Filter: Find posts by keyword, date range, or specific usertags.
• Sort Everything: View posts by Most Liked, Oldest, or Newest.
• Auto-Scroll: Automatically loads a profile's entire history so you don't have to keep scrolling manually.
• Analytics Dashboard: Engagement rate, viral/outlier post detection, posting frequency, content breakdown, and CSV/PDF export.
• One-Click Copy: Quickly grab post links for sharing.
• Enlarge Media: Easier viewing for images, carousels, and profile pictures.

It's free and doesn't collect any user data — everything runs locally in your browser. Check it out here: https://chromewebstore.google.com/detail/grid-insights-%E2%80%94-profile-a/gpdehfapgdgijoejkdchhjomnlfokoni

Would love to hear any feedback or feature requests!

This happened twice this month — a free trial ended without me noticing and I got charged, then I realised I was still paying for two streaming services I don't even use. Checked my bank statement and it was more than I expected.

So I built a chrome extension called Renewal. You add your subscriptions in — name, price, renewal date — and it totals up what you're actually spending monthly and yearly, instead of finding out from your bank statement when it's too late.

Free version tracks up to 3 subscriptions, which honestly covers a lot of people. There's a paid tier too (unlimited subscriptions, a countdown badge on the toolbar, desktop alerts before something renews, spending by category) for anyone who wants to go further with it.

Genuinely curious if this is actually useful to other people or just something I built for myself. Link's below if you want to poke at it.

If you could, I would really appreciate if you checked it out and gave it a review. Everyone has access for 60 minutes a day, about an hour of learning which is what most people tend to do.

It works on plenty of services as of right now, my favorites are Netflix and Prime. For it to work, it needs a show that has the audio and/or subtitles in that language that you are learning. I tried to not have it use any API credits so it doesn’t require an account or cost money unless you want unlimited watch time, $3/Month or $10 lifetime.

Please let me know what I could improve on, in general or UI wise, maybe what you would want to see it do next? Thank you.

I open 50+ tabs a day, and Chrome’s default page feels increasingly cluttered with trending searches, suggested junk, and noisy search results. Most third-party startpages swing to the other extreme: bloated widgets (weather, stocks, notes) that slow down load times.
I’m prototyping a local-first, minimal New Tab extension focused on three things:
1. Clean Search: A fast search bar that defaults to clean, text-only Google results (⁠&udm=14⁠), bypassing AI overviews and ad carousels.
2. Visual Bookmarks: Automatically reads your native Chrome bookmarks into clean visual cards—no manual importing or link accounts.
3. RSS Reading Radar: A minimal 3–5 headline stream from your favorite blogs/Substacks directly below, with zero algorithmic feed noise.
The rule: Local-first, loads in <15\text{ ms}, zero tracking, zero setup fatigue.
Feedback wanted:
What does your current New Tab look like (default, blank, or an extension)?
Is a live RSS radar on your startpage useful, or would you prefer just search + bookmarks?
Roast the idea—brutal honesty appreciated.

A few months ago, I started building a small Chrome extension to solve a problem I had myself: actually finishing the huge YouTube playlists/courses I kept saving.

That side project became PlanYT (https://planyt.vercel.app) and now it's just a few users away from hitting 100 users.

The current v1.3 includes:

• Video-by-Video & Custom Schedule planning
• Per-video progress tracking
• Speed-aware planning (1x, 1.5x, 2x, etc.)
• Progress widget directly inside YouTube
• Local browser storage, no accounts or tracking

It's definitely not perfect yet. I'm still working on better UX, smoother workflows, and more features.

Still feels pretty cool seeing something that started as a personal tool slowly turn into something other people actually use.

Would love to hear any feedback or suggestions!

Hey everyone!

I built Shortie, a simple Chrome extension that lets you create custom shortcuts for quickly opening websites and URLs from the address bar.

I’ve been using it myself and would love to get some honest feedback from other Chrome users.

https://chromewebstore.google.com/detail/shortie/jokcmkhbnkjppppicmfadkjlafpcbkod

Try it out and let me know what you think — especially anything you’d improve or change. Honest feedback is very welcome!

Most of the day is spent in the browser, so having to open another app just to take a quick note can add unnecessary friction.

The goal was to have one place where notes, focus sessions, and productivity tools are always available without leaving the browser.

The extension combines:

* Quick notes with a rich Markdown editor similar to Notion
* Shortcuts and useful links
* Boards for organizing notes
* Website blocking for distracting sites
* Ambient sounds and background noise
* Focus sessions with labels such as work or study
* Detailed statistics to see how time was actually spent

Everything lives inside the new tab, turning it into a personal productivity workspace instead of just an empty page.

Really looking for honest feedback.

What feels useful? What feels unnecessary? What would you change or add?

If you want to try it, here’s the extension:

[Extension link]

After 5 months of developing this project and over a hundred continuous improvements, Focus Mode has reached 1,000 users 🥹🎉

At first, this was just another project, but with patience and a constant drive to make the best extension possible, I finally made it happen!

Good things take time, I wish you success and hope you achieve even your wildest goals.

Thank you all for this incredible adventure 🫶 and for all the support I’ve received throughout this project!

Keep believing! 🔥

Happy building!

I built a Chrome extension for annotating live web pages and then screenshotting them. Fully client-side, no account, no server. That was a deliberate choice and I still think it's the right one, but it means I know almost nothing about the people using it.

Two things running today. A prompt in the extension that routes happy users to the store review page and unhappy ones to a bug and feedback form. And an uninstall form asking why they left. Between them I get a handful of replies a week.

Most of the useful stuff has come from Reddit threads instead.

What else is there? How you guys find a way to actually talk to your users?

Why it's boring

(Even the name is boring - Transcript to PDF & Markdown for YouTube)

There's no AI in it. No summarization, no "chat with this video," no accounts, no cloud sync, no subscription. It doesn't try to tell you what the video is about — it just gets you the actual text, cleanly formatted, so you can do whatever you want with it. That's it. In a world of AI-wrapper extensions, this one is deliberately the opposite: it's a formatter, not a feature.

The pain point

YouTube's own transcript panel is technically there, but it's miserable to actually use — no search, no clean export, and copy-pasting it dumps a wall of text with timestamps jammed into every line. If you're a student turning a lecture into notes, a writer pulling source material from a talk, or you just want to paste a video into ChatGPT/Claude without hand-scraping the transcript panel, there's no good way to get from "video" to "usable text" without some manual cleanup. This just skips that step.

Why I built this one

I'd already solved the hard technical problem for a bigger product I run (SavePosty) — the actual transcript extraction is not trivial (more on that below) — and it occurred to me it'd take almost no extra effort to strip that piece out into its own free, standalone tool. No backend coupling, no auth, nothing to onboard — just the transcript extractor and an export UI. Built in a few days because the hard part was already proven in production elsewhere.

Why it's free

No monetization in this version, on purpose. It's an audience/volume experiment more than a product — I wanted to see if a genuinely useful, no-nonsense tool gets traction on its own merits. Honest kill criteria I set for myself: if it doesn't cross a few hundred installs with organic reviews in the first 90 days, I unpublish it rather than keep pushing a tool nobody wants. If it does get real usage, the plausible next step is something like bulk/playlist export, not slapping AI features on it — that space feels commoditized to me already.

If you regularly shop on AliExpress, I built a small Chrome extension called XpressCoupon to make finding current coupon codes easier.

Instead of searching through old Reddit posts, expired coupon pages, or trying codes one by one, the extension gives you quick access to the latest AliExpress coupon information while you browse.

What XpressCoupon is for

✅ Find current AliExpress coupon codes faster
✅ Check available discounts before placing an order
✅ Keep up with major AliExpress sales and promo periods
✅ Quickly access XpressCoupon tools and coupon resources
✅ Avoid wasting time testing obviously expired promotions

I created it mainly because AliExpress coupon codes change constantly, especially during events like Choice Day, Anniversary Sale, 11.11 and Black Friday.

The extension is still being improved, so feedback from this community would genuinely be useful.

Chrome Extension:
XpressCoupon - Aliexpress Coupon Codes

If you try it, let me know what you would like added or changed.

Disclosure: I created XpressCoupon and also run XpressCoupon.com. Some links or offers available through XpressCoupon may be affiliate links.

Hi! Am new to this. So hello! I have been creating a chrome extension to reference and explain institutional and technocratic language. You think that is something people might be interested in? Do not wish to advertise, just looking for people that also feel like we need to do something to keep our language clean and like chrome extensions :) If interested I can of course give directions to the extension.

I built this because I kept getting 5-minute voice notes at work and had to listen to all of them to find one useful sentence.

What it does: adds a "Transcribe" button under every voice message on WhatsApp Web. Text shows up inside the bubble. It can also summarize a long audio, generate meeting notes for a whole conversation, and answer questions about what was said.

The part I care about, and why I'm posting here: there is no server of mine in the middle. The extension talks directly to whichever AI service you configure, with your own key. Groq's free tier (~8h of audio/day) is the default, OpenAI works, and Ollama works for summaries if you want nothing leaving your machine at all. The key stays in local storage, not synced.

Permissions: storage + WhatsApp Web + Groq. OpenAI and Ollama are optional host permissions, requested only when you pick them. No remote code.

Heads-up before you install: the UI is in Brazilian Portuguese for now (transcription itself works in any language Whisper handles). English UI is next if there's interest.

Happy to answer anything about the MV3 side — capturing the audio was the hard part, since WhatsApp doesn't keep the <audio> element in the DOM.

Update to my ChatGPT chat organizer: segregated chats can now be fully hidden from Recents, not just badged.

New optional toggle — when on, segregated chats disappear from ChatGPT's main sidebar entirely and only live in their own section. Off by default.

Still:

- Tag any chat as segregated from the sidebar

- Dedicated section keeps them out of your main history

- One-click unmark if a chat turns out to matter

- 100% local — no backend, no tracking, no account

Not the same as ChatGPT's own "Temporary Chat" mode — works with your normal, permanent chats.

For all the successful extension makers, how did you promote your products and how did it become a success?

Hi everyone,

I recently built a small Chrome extension called ImageLite – Image Format Converter.

The idea is simple: when you find an image on the web, you can right-click it and convert/save it directly as:

• WebP
• AVIF
• JPEG
• PNG

There’s no need to download the image first and then upload it to an online converter.

Everything is processed locally on your device. There are no uploads to external servers, no account required, no ads, and no tracking.

You can also adjust the quality for WebP, AVIF, and JPEG, and choose whether files are downloaded automatically or Chrome asks where to save them.

I originally built it because I wanted a faster workflow for working with web images, and I’ve now published it on the Chrome Web Store.

Chrome Web Store:
ImageLite – Image Format Converter

It’s free. I’d really appreciate any feedback, especially if you encounter an image or website where the conversion doesn’t work as expected.
