We’re two engineers who built a system that acts like a guardrail/policy enforcement layer for large language models (GPT, Claude, etc). It analyzes both prompts and responses in real time, and applies configurable policies like:

Blocking PII (emails, IPs, phone numbers, etc.) Detecting company secrets (e.g., passwords, API keys) Preventing accidental leaks of proprietary code Filtering toxic/inappropriate language Catching mentions of competitors, people, or locations Each policy can be tuned (strict or lenient), and you can decide whether to just log it or actually block the message. Everything is logged with full metadata: policy IDs, timestamps, token counts, etc.

The architecture has two parts: a self-hosted data plane (which handles all sensitive message content), and a hosted control plane (for configs and API keys). So it can be used in privacy-sensitive environments.

You can integrate it via API, browser extension, or a simple chat UI.

Now here’s where we’re struggling:

We don’t have a strong network of buyers or investors. Most of our outreach has been cold emails, and it hasn’t led to much traction. Pricing experiments (per seat, per org) haven’t helped. So it’s unclear whether the idea isn’t good—or we’re just not getting it in front of the right people.

We’ve started thinking about open-sourcing it. The idea would be: self-host for free, pay us if you want the hosted version (similar to MongoDB/Redis models). Probably support bring-your-own-encryption-key for hosted users.

But I’m honestly torn. Open-sourcing sounds right for trust and adoption—but we’ve spent a lot of time on this, and there’s that fear of releasing it and getting little to nothing back.

So: if you work with LLMs, or have faced issues around privacy/compliance/safety, I’d really love your take. Does this sound useful? Would open source make it more attractive? Are we just early to a problem people don’t feel yet?

Not promoting anything, just hoping to learn from folks who’ve walked this path.

The Nintendo Switch 2's official specs aren't too different, but the new console has a lot of upgrades on the original Switch.

The $450 console will get Mario Kart World as a launch title, games in 4K resolution and new GameChat communication features.

According to reports, the FAA's move to hide ownership details might not stop those who post private jet details on social media.

Some Nintendo Switch games, like Breath of the Wild, are getting upgraded versions for the new console called Nintendo Switch 2 Editions.

Commentary: I tried the Minecraft-themed McNuggets sauce. It might just be the hottest sauce Mickey D's has ever offered.

Hey HN,

Three months ago, I decided to shift careers into software development and indie entrepreneurship. This is my second web app since then.

The idea came from a simple, frustrating experience: I needed to organize a meetup with multiple possible dates. I looked for a quick tool to create a poll... and finally decided to use a group chat instead...

So I built quickpoll.cc – an AI-powered tool that lets you create scheduling polls just by describing what you want in plain language. For example:

“A team dinner next week with options on Tuesday evening, Thursday lunch, or Friday afternoon.”

It instantly turns that into a shareable poll. No sign-up, no fluff, no waiting.

Highlights: - No account needed - Available in English, French, and Spanish - Totally free (just a small promo for my first mobile app) - Designed to be simple and fast - Works well on desktop and mobile

This was mostly built to solve my own problem, but I’m hoping it can help others too. I’d love your feedback on: - How well does the natural language processing handle your inputs? - Any bugs or usability pain points? - Ideas for improvements or other use cases?

Appreciate your time!

Br. Alessandro
