Idea #1
A Chrome Extension That Organizes Your Browsing History with AI-Powered Summaries
yep! I have it scrape the page before the tab is closed to summarizes + tag them for primarily usefulness. uses stuff like time spent and scroll etc. not sure what else I'll do with the data yet, but want to collect like a years worth and see what I can pull from itBefore you close a tab, it scrapes the page, summarizes the content, and tags it based on how long you stuck around and how much you scrolled.
Uses something like Qwen3-8B, which runs locally (just 4–5GB RAM), so your data stays on your machine, not someone else’s server.
It builds a searchable archive of what you’ve read, watched, or skimmed… so instead of “I think I saw that somewhere,” you can actually find it, with context.
Perfect for students, researchers, or knowledge hoarders who want to make their browsing history actually useful for once.

Want agency clients without spamming Upwork or begging in cold DMs?
Here’s the $0 play that’s landing dev gigs right now.
Open Meta Ads Library. Search by job-to-be-done.
Use terms like:
“We run ads for”
“Meta + Google Ads”
“Lead generation agency”
“Ad experts”
“PPC for small business”
“Get more clients”.
Then scroll the preview. You’re looking for agencies running done-for-you ad services. They’ll usually promote their packages, show screenshots, or invite you to book a call.
Those are the people who desperately need better sites for their clients (and themselves).
Now here’s what you say:
"Ever run into clients with god-awful websites that tank conversions? I help ad folks like you rebuild client sites. Custom code. Want help?"
You’re not pitching web development. You’re pitching better ad performance. It’s riskless for them. It makes them look good.
And it doesn’t take more than 5–10 messages to land a call.
No cold list. No scraping. Just the Meta Ads Library and a bit of common sense.
Meta’s showing you who’s spending and probably leaking conversions. Now go message ’em.
P.S. You don’t even need to own the agency or be a dev.
You can run this play as a deal maker. Match both sides, track results, and get paid on performance. Win-win-win.
Idea #2
A Chrome Extension That Alerts Users to Companies That Prioritize Foreign Workers
Sadly for the Wall of Shame, I ended up with 65,859 distinct companies using the H-1B to deprive Americans of Work.
So you will need to zoom in to your city to see what is happening locally.
You will find two outcomes:
1) you can view the corporate executives compensation AND the H-1B applications they have filed for 2024 or
2) you can view the H-1B applications they have filed for 2024 if they are not a publicly traded company.
I do hope to add in the ability to search by ticker symbol for the large pubicly traded firms, but not today.
https://guestworkervisas.com/wallofshame.phpIt cross-references the site against a massive dataset (65,000+ companies from 2024) and pops up a quick alert:
“This company filed H-1B applications in 2024, here’s what you should know.”
You’d get links to more info too, how many visas they filed, executive pay (if they’re public), maybe even a direct link to USCIS records.
Built for folks who want transparency in hiring practices and don’t want to accidentally support companies that prioritize cheap imported labor over local talent.
Inspired by tools like H1B-ify, but this one works across all company websites, not just job boards.

Idea #3
A Chrome Extension That Uncovers Hidden Web Parameters and Endpoints
Created a private bookmarklet packed with features to extract hidden paths, URLs and endpoints. It fetches data from HTML elements, inline scripts, quoted strings, performance logs and even external JavaScript files for deep reconnaissance.You visit a site, hit a button, and it scrapes the page. HTML, inline scripts, quoted strings, performance logs, external JS, everything.
Then it spits out endpoints, parameters, hidden links, and other juicy recon data in a clean interface.
It could even highlight stuff directly on the page and let you export findings for later.
Perfect for bug bounty hunters and devs tired of wasting time hunting for stuff that tools like Arjun or ParamSpider sometimes miss.

Idea #4
A Chrome Extension That Simplifies Comparison Shopping with AI-Driven Product Alternatives
AI is crushing search for comparison shopping. Try this prompt:
I currently buy [current product name and manufacturer]. Find me the top three alternatives and focus on [features you want : price, feature 1, ewg rating etc]. Give me the results in a table with all information.You punch in what you’re looking for. Like “cheaper,” “cleaner ingredients,” or “EWG rating above 4”. The extension scans the web in real time, then shows a simple table with your product vs. the best 3 matches based on what you care about.
No more bouncing between review sites, pricing tools, or comparison blogs.
It could also track prices over time, send alerts, and link you to trusted reviews. All while you stay on the page you were already shopping from.
Kind of like Gizzmo… but with brains.
Built for people who hate wasting time and love getting a better deal.
