Recently I developed voice_convertor application which can work fully offline.
The client asked me to build it was musician (my thought) from Los Angels. He was a fan of Michael, a well-known singer in his region and had been using Voqul to convert othe similar singer's voice into that Michael's style. But, he faced several limitations, which the tool was cloud based, had unstable connectivity, and the output quality was inconsistent.

He asked me to build a fully offline solution with higher-quality results and real-time capabilities.

To train the model, he provided around 20 audio tracks (each ~3 minutes long). Based on this dataset, I developed a voice conversion system that runs entirely offline. The application includes the following features (actually this is a simple app).

1. File-to-file voice conversion

2. Real-time voice streaming

3. Pitch control for fine-tuning output

4. Optimized inference for low-latency performance

A lot of teams hear simulation and think:

• more realism

• more complex AI

• better physics

That s usually the wrong goal.

A good simulation isn t valuable because it s realistic.
It s valuable because it creates meaningful outcomes.

We built iQuelo Lead Prospector to help field sales teams prospect smarter, prioritize better, and reduce the cost of selling.

Instead of using disconnected tools for lead discovery, routing, and follow-up, we wanted one workflow that actually helps teams execute.

Would love your feedback from the Product Hunt community.

I'm the founder of Fundolink and I built this because I was tired of watching founders give away equity they didn't have to.

The problem: Every fundraising platform out there is built for investors. They post what they want. Founders compete to meet their criteria. The power dynamic is completely backwards.

What Fundolink does differently: Founders come in, define their own deal equity, revenue share, loan, convertible note, whatever fits their vision and our AI matches them with investors who align with those terms. Not the other way around.

Why this matters: The best founders aren't always the best negotiators. And a lot of great companies die because a founder signed a bad deal in a desperate moment. We're changing that.

Most people think lead-gen is just about asking for an email. I built Interactify to prove it s about making the decision for them.

In this demo, I show how to build a "Tech Stack Architect" recommender. Instead of just a generic quiz, this engine uses a specialized logic layer to weigh user answers and match them with specific solutions.

I designed this to be "One Brain." You manage your products, set logic weights for each answer, and the engine calculates the winner in real-time. No code, just logic.

Watch the build here:

Download the model once. Use it forever. Even in airplane mode.

Solo dev. No VC. No team. Just one app that does what cloud AI won't respect your privacy.

Hey PH community!

We're launching Agent Browser Today (April 9) and wanted to share it here ahead of the launch.

I read 16 IRS publications from Korea. Then I found several government audit reports from the GAO. Here's the number that stopped me cold.

I am not American. I've never filed a Schedule C. I've never spoken to the IRS.

But I was already building a product for 31 million U.S. self-employed people. So I needed to understand their tax reality.

16 IRS publications. Multiple audit reports. Hundreds of pages. One month.

Go to Market for B2B SAAS is not easy. Starting with cold out reach, I am currently trying a variety of tools to improve our cold outreach.
Here's what I'm planning to try or have tried

• Instantly

• Apollo

• Hunter.io

• Attio

• Gojiberry

• Lead Bay

• Lightfield

• Hubspot

What is everyone else using?

Hi PH! I m Alex.

I spent the last year reading reports, and realized this: Corporate ESG

budgets are often wasted on vague "awareness campaigns." Data proves
