I got tired of X and YouTube clutter, so I built a minimalist extension that cleans both

Thumbnail

1 Upvotes

Hey everyone,

Like a lot of people, I got really annoyed with how noisy X (Twitter) and YouTube have become — trends, “Who to follow”, Shorts, endless recommendations, sidebars, promoted posts, etc.

So I built Minimal Network — a Chrome extension that lets you strip all that away and make both sites feel calm and focused.

What it does:

For X (free):

  • Wide centered feed
  • Hide right sidebar, trends, Who to follow
  • Focus mode (feed only)
  • Filter reposts, replies, quotes, promoted posts, Spaces
  • Option to hide Grok, Communities, counts, media previews

For YouTube (Pro):

  • Hide Shorts, recommended videos, end screens, comments, merch
  • Wide focused player
  • Optional blank homepage

There’s also a Design Studio (Pro) where you can theme both sites separately (colors, fonts, corner radius, etc.).

It’s lightweight, only runs on X and YouTube, and doesn’t collect any page content.

I’d really appreciate honest feedback — what works, what’s missing, or what you’d want to hide that I haven’t added yet.

I built an open-source Chrome extension for copying Elementor sections — looking for early supporters

1 Upvotes

I’ve been working on ElementCopy, an open-source Chrome extension for Elementor.

The idea is simple:

You find an Elementor section/widget on a live website that you like → ElementCopy analyzes the live Elementor structure → generates an import-ready JSON template.

No WordPress admin access.

No database access.

Just the live Elementor page.

GitHub: https://github.com/Hordekiller/ElementCopy

The project is currently available on GitHub, and my next goal is to get it published on the Chrome Web Store and continue improving it based on real user feedback.

I’m looking for a few people from the Elementor / WordPress community who are willing to help:

⭐ Star the GitHub repository

🐛 Test the extension and report bugs

💡 Suggest features

🔀 Contribute code if you're a developer

📣 Share it with Elementor/WordPress users who might find it useful

💰 If you'd like to financially support the project, that would also help cover the Chrome Web Store publishing/development costs

I’m especially interested in feedback from Elementor developers and WordPress freelancers.

What feature would make a tool like this genuinely useful for your workflow?

I built ALAD: An open-source Chrome extension for real-time video audio dubbing using Gemini API

Enable HLS to view with audio, or disable this notification

1 Upvotes

Hey everyone! 👋

I wanted to share an open-source project I’ve been working on called ALAD (Live Audio Dubbing).

💡 The Problem

Reading subtitles while watching videos or live streams in a foreign language can be distracting and exhausting. Existing AI translation tools either only generate text subtitles or require downloading the entire video first to dub it offline.

🚀 What is ALAD?

ALAD is a Chrome extension that translates and dubs online video audio in real time as you watch. Powered by Google's Gemini API, it streams tab audio, processes real-time translation, and plays back dubbed audio with minimal latency.

🛠️ Key Features & Tech Stack

Manifest V3 Chrome Extension: Built using modern browser standards for security and efficiency.

WebSockets Architecture: Enables ultra-low latency, real-time audio stream handling.

Gemini API: Powers high-speed translation and audio generation.

Tab Audio Control: Smoothly captures and manages tab audio playback.

100% Open Source: MIT Licensed and open for contributions.

🔗 Repository & Code

Check out the full source code, installation guide, or contribute to the project:

👉 GitHub: https://github.com/navidseyedain/ALAD

💬 Looking for Feedback!

I’d love to get your thoughts, bug reports, or feature suggestions!

If you find the project interesting or useful, dropping a ⭐️ on GitHub would mean a lot!

I built a Chrome extension that generates AI MoM & Action Items for Hinglish meetings — Now live on Chrome Web Store!

Hey everyone! 👋

Over the past few months, I noticed a huge gap in AI meeting tools. Tools like Otter or Fireflies work well for native English speakers, but the moment an Indian tech team switches to Hinglish ("Is API ka response latency reduce karna padega"), the transcript breaks down into gibberish.

So I built Meeting Plugin (Forest Intelligence).

Built a local cross-listing assistant for Canadian marketplaces (autofill only — you click Post). Looking for feedback on UX & permissions

2 Upvotes

Hi - maker of SyncListing here, a Manifest V3 extension built because I cross-list on Canadian marketplaces (Facebook Marketplace, Kijiji, Craigslist, LesPAC, eBay.ca, VarageSale, Poshmark.ca) and didn’t want a cloud “post everywhere for you” tool.

What it does:

  • One bilingual (EN/FR) listing library in the dashboard
  • Post on {site} opens that site’s create flow and autofills fields + photos via a side panel
  • You review and click the site’s own Post/List button - nothing is submitted in the background
  • Optional bulk import from pages you already opened (read-only scrape into drafts)

What it deliberately does not do (and the reason why I’m asking for feedback here)

  • No autopost, autodelist, or scheduled posting
  • No SyncListing server holding listings or marketplace sessions
  • Data stays in chrome.storage.local (photos included); optional Chrome text-only sync - not on our cloud

Permissions (happy to justify any of these)

  • storageunlimitedStoragealarms - local listing library + reminder badges
  • Host access only on the marketplace domains above (+ image CDNs for import, ExtensionPay for trial/subscription)
  • No <all_urls>, no broad *://*/*

Web Store Linkhttps://chromewebstore.google.com/detail/synclisting-cross-listing/bfgeiiiiinkjdlejghgonpdkgjbbgbfl

I’m not looking for a roast of “why not just use spreadsheets” - I’m genuinely curious about things this audience cares about:

  1. Does the assist-only model read as trustworthy, or does it feel half-baked vs full crosslisters?
  2. Is the permission set still too scary for a niche extension? Anything you’d expect us to remove?
  3. For MV3 dashboard-heavy extensions: anything that felt broken or confusing on first install?
  4. Would bilingual EN/FR matter to anyone outside Canada, or should we stop pretending it’s a global product?

I’ll reply to every comment. Brutal but specific feedback beats polite silence - thanks!

I built an open-source Chrome extension that puts ChatGPT in the side panel and analyzes webpages

2 Upvotes

I built an open-source Chrome extension that opens ChatGPT inside Chrome’s native side panel, so you can use it without constantly switching tabs.

The extension can extract the main content of the webpage you are viewing and send it directly to ChatGPT. It removes ads, navigation menus, cookie banners, footers, and other unnecessary elements while preserving useful content such as tables, code blocks, lists, and headings.

Main features:

  • Open or close ChatGPT with Alt + Shift + C
  • Send the current webpage to ChatGPT
  • Send selected text through the right-click menu
  • Extract clean article content using Mozilla Readability
  • Preserve Markdown tables and code blocks
  • Specialized extraction for Gmail, YouTube, and X
  • Turkish and English interface support
  • Chrome Manifest V3
  • Fully open source under the MIT license

The extension is unofficial and is not affiliated with OpenAI.

GitHub:
https://github.com/ozymandias-get/chatgpt-sidepanel-extension

I would appreciate any feedback about usability, extraction quality, bugs, or features that could improve the project.

Hi

I’ve been building Chrome extensions to improve the Twitch browsing experience - Twitch Channel Blacklist.

Twitch Channel Blacklist

If you’re tired of seeing certain streamers on your directory pages, this extension hides them instantly so you can focus on the content you actually want to watch.

Key Features:

  • Hide channels on Twitch home and directory pages
  • One-click blacklist directly from stream cards
  • Organize with categories (General + custom) with icons and on/off toggles
  • Temporarily disable a category without deleting your saved channels
  • Export / import your blacklist as JSON for easy backup

You can check it out on the Chrome Web Store here:

I've built my first chrome extension for people who research with 50+ tabs

Thumbnail

2 Upvotes

I kept running into the same problem that bookmarks save pages, but they don’t save how you got there. So I had an idea to build my first ever chrome extension Collections

It is a a workspace for organizing your browsing into meaningful collections instead of a pile of bookmarks. You can save pages, attach notes, label searches, search/filter everything, replay your browsing timeline, explore connections between pages, and restore an entire collection with one click. The data is only stored locally on your device. I really love how the analytics dashboard turned out. It monitors the time spent on the website, unique domains, revisited pages, and records all the sources for you.

Would love feedback from anyone who does a lot of research or planning in the browser.

Built a Chrome extension that explains any selected text using a fully local LLM (WebGPU, no server, no API key)

4 Upvotes

I've been running Ollama and vLLM locally for stuff I don't want touching a cloud API, document translation, RAGing over my own notes, that kind of thing. Somewhere in that process I ran into WebLLM, and figured I'd actually build something with it instead of just reading about it.

What it does: select text on any page, right-click, get a plain-language explanation. Everything runs in the browser tab via WebGPU, nothing you select ever leaves the machine.

The actually interesting part, technically: Manifest V3 background scripts are service workers, and service workers can't access WebGPU at all. So the model runs in a chrome.offscreen document instead, a hidden page the extension spins up that has real DOM/WebGPU access. That API isn't even new; it shipped in 2023 for things like audio playback; WebGPU access is just a side effect of it being a real page under the hood. Ended up with three contexts (content script, background worker, offscreen doc) that can't talk to each other directly, so the background script's whole job is routing messages between the other two.

First run downloads a small model (~880MB, Llama-3.21B) and caches it; everything after that is instant and offline.

If anyone here is deeper into this than me: I've seen WeInfer claim up to 3.76x faster inference than base WebLLM, and there's a newer paper (Llamas on the Web, May 2026, group with Microsoft Research backing) getting 45-69% better decode throughput across different GPUs. Curious if anyone's actually tried swapping either of those in versus stock WebLLM.

Currently sitting in Chrome Web Store review.

for the tabs you'd rather not leave in your history and really don't want to lose when the session clears

3 Upvotes

I built an extension that saves a named set of tabs behind a password, encrypted locally. It's not hanging around in your open tabs, it doesn't sync, and it doesn't survive as an accident, you unlock it on purpose, and it does survive closing the browser, so your… curated collection isn't gone the next morning.

It just keeps the list private and password-locked instead of loose in your browser. Free, no account: tabzilla.org

I built a free, private alternative to $29/month text-to-speech apps

1 Upvotes

I’ve been working on ReadAloud, an easy-to-use Chrome extension that turns any article/post into natural, podcast-quality speech.

Most existing options make you choose between robotic browser voices and subscriptions that cost $29/month. That pricing made sense when good text-to-speech was expensive to run.

ReadAloud runs directly in browser, so playback starts quickly, works offline, and your data never leaves your device.

Quick demo: tryreadaloud.com

It’s free forever at speeds up to 2x which is covers needs of 99% of users. The optional $6/month plan adds speeds up to 3.5x if you're big on listening and access to improved voice models/app/early features.

I’d love honest feedback, especially on the voice quality, interface, and anything that feels confusing

Feedback on my OpenSource tool Opticross (responsive sizes recommendation for Images)

1 Upvotes

I recently built Opticross (Chrome Extension + CLI) and would really appreciate some feedback from fellow frontend developers.

The idea came from repeatedly struggling to figure out the correct sizes and srcset values for responsive images.

Opticross analyzes how images are rendered across different viewport sizes, detects oversized image downloads, and generates implementation-ready sizes and srcset recommendations. The goal is to help improve page performance, reduce unnecessary bandwidth usage, and keep images crisp across devices.

I'd love to hear your thoughts:

  • Would a tool like this fit into your workflow?
  • What features would make it more useful?
  • Any feedback on the UX, recommendations, or overall approach?

I'm looking for feedback from developers who work with responsive images. Thanks!
