Hey PH community,

I've been building FounderSignal over the last few weeks and wanted to share it here.

Mask sensitive fields before screen sharing with scope, partial masking and page-scan controls.

Screen Share Privacy Field Masker helps protect sensitive information while browsing, recording tutorials, sharing your screen, taking screenshots, preparing demos, handling support calls, or working with client data. The extension can hide common sensitive data such as email addresses, phone numbers, names, addresses, usernames, company fields, card numbers, IP addresses and your own custom words or phrases. It can also blur images and videos separately, with an intensity control and one-click media blur toggle. You can run protection across the full browser, only on the current Chrome tab, only on specific URL rules, or ignore pages where masking is not needed. Choose full masking or partial masking by percentage or fixed digits/chars. For pages where you only want to hide specific fields, use Page Scan. It scans the current page, shows detected sensitive fields, and lets you save only the fields you want to mask for that URL. Screen Share Privacy Field Masker includes a 7-day trial and paid license activation. Customers can start a trial with email signup, sync an active subscription by email, open the pricing page, and activate with a license key. The extension stores masking preferences locally in Chrome browser storage. Page content and custom masking rules are processed locally in the browser and are not uploaded to the license server.

Over the past few months, I've been really impressed with Claude for stock research. However, I often found myself still juggling different tools to pull certain things (price charts, live information, etc.).

So I made a connector for Claude that let's you pull in real-time information--charts, financials, earnings, institutional ownership, etc.--into a consolidated report.

I've found it helpful and just wanted to share--totally free to use:

Options trading has a massive learning curve, and most educational resources either dumb it down to uselessness or throw you straight into the deep end with the Black-Scholes formula and wish you luck.

I'm a high school sophomore, and after getting interested in finance, I built StrikeLab an interactive options pricing education site that lets you actually play with the variables behind Black-Scholes (strike price, volatility, time to expiry, etc.) and see in real time how the option's value changes.

A few things I ran into building it:

• Making math intuitive without hiding it is genuinely hard. Most "beginner" explainers avoid the formula entirely, which means users never build real intuition.

• Volatility is the variable people understand least even people who trade options regularly. Visualizing it helped a lot.

• The gap between "I understand the concept" and "I can apply this" is where most learners fall off.

I've spent the last year figuring out how Reddit actually works as a marketing channel.

Not the spammy way. The right way.

I learned which subreddits convert, how to write posts that don't get removed, how to start conversations that naturally lead people to your product, and how to do it all without triggering mods or looking like a bot.

The results surprised me. Reddit drove more genuine interest than any other channel I've tested.

Most founders ignore Reddit. Big mistake.

Reddit users are actively searching for solutions. not passively scrolling. One genuine post in the right subreddit can outperform a $500 ad spend.

The secret? Don't pitch. Add value first.

• Share a real insight or story

• Mention your product naturally as a solution

• Reply to every comment to keep the thread alive

A while back, I needed exchange rate data for a small personal project. Nothing fancy just convert a few currencies, maybe pull some historical rates for a simple chart.

So I did what most developers do: went to RapidAPI, picked the first free currency API that looked decent, and integrated it.

It worked. Until it didn't.

When I first launched FreeViralKit, the goal was simple: give YouTubers free SEO tools without the crazy $30/mo paywalls. The response was amazing, but I knew the platform could be better.

Today, we just deployed the biggest update yet: Stunning New UI: We completely revamped the interface. It s faster, cleaner, and looks incredibly premium. Smarter AI Engine: We tweaked the backend prompts to ensure the tags and hashtags generated are even more optimized for YouTube's 2026 algorithm. Squashed Bugs: Fixed the markdown rendering issues in the Script Generator so your output is perfectly formatted every time. New Resources: We just dropped a comprehensive new guide on mastering YouTube Tags to get your videos ranked faster.

The best part? It is still 100% free. No signups. No paywalls.

Check out the new updates here and let me know what you think of the new design!

Don't get me wrong, I love the idea. Installed it day one, played with skills, even wrote a few custom ones.

But on my actual messy desktop (20 Chrome tabs, 3 Office apps, VPN, weird folder structures), it fails ~40% of the time.
Not because the model is dumb because the execution layer has no tolerance for real-world chaos.

• A popup appears -> agent freezes

• File name typo -> agent gives up

• App not in foreground -> click misses

I know I could write more robust skills, but that defeats the voice and forget promise.

Noticed something during my internship recruiters were spending 2-3 hours DAILY just going back and forth on WhatsApp trying to fix interview times.

"Are you free Tuesday?" "No what about Wednesday?" "Morning or evening?" "Let me check with the manager..." "Sorry that slot is taken now"

Literally 10 messages just to book ONE interview slot.

So I built a WhatsApp bot that handles this automatically. Candidate gets a message replies however they want slot confirmed. No human needed.
