Built a tool to test AI APIs and chatbots before release

We ve been building PromptBrake a platform for testing AI APIs and chatbots before they go live.

The idea came from seeing more teams ship AI features without really knowing how those systems behave under adversarial or unexpected input.

PromptBrake runs real-world attack scenarios against the actual endpoint your app ships to help uncover things like:

  • prompt injection

  • jailbreaks

  • unsafe responses

  • data leakage

  • tool misuse

  • off-script chatbot behavior

What tool should I add next?

Most developer tools waste time before they save time.

That frustration is exactly why I built DevUtilityLab.

A simple platform with instant tools developers actually use daily:

SQL Formatter
JSON Beautifier
CSV JSON Converter
Minifiers & Validators
Clean UI without unnecessary clutter

Launched FieldLine yesterday — a phone system for home-services operators — feedback wanted

Hey PH

I'm Tudor, a solo developer from Romania, and I launched FieldLine yesterday. I don't use social media much and I don't have a community to share this with so this forum is basically it.

FieldLine is a phone system built for US home-services operators HVAC, plumbing, roofing, electrical. Dedicated numbers per technician and per ad channel, every call recorded and transcribed, AI summary on every call, and a structured lead card the moment a call ends. No softphone. No CRM to learn. Two-minute setup.

I just launched Drop-Kit — a free tool that turns any link, tweet, photo or text into a post

Hey Product Hunters! I'm Caroline, and I just launched Drop-Kit a free tool that turns any link, tweet, photo or text into a beautiful social post image.

The itch I was scratching: I kept wanting to share articles, product links, or quotes on social media, but making them lookgood was either too slow (design tools) or too ugly (plain screenshots). So I built the thing I wanted.

What it does: Drop in a URL, paste some text, or upload a photo pick a style download or copy to clipboard. That's the whole loop.

Would you let AI guide your business?

We re building RevCore.AI an AI GTM copilot designed to help B2B SaaS teams: Identify their best-fit customer Detect wasted ad spend and pipeline inefficiencies Generate AI-powered outbound messaging and campaign ideas Improve conversion rates across sales + marketing Turn GTM decisions into measurable revenue outcomes The vision is simple: Instead of teams guessing where to spend money, who to target, or what messaging converts RevCore helps them see the highest-leverage opportunities instantly. Still early, but we re actively building and would love honest feedback from: * SDR leaders * Founders * Demand gen teams * RevOps/GTM operators * B2B marketers A few things I d love thoughts on: 1. What s the hardest part of building predictable pipeline today? 2. What GTM tools do you feel are overcomplicated? 3. Would you trust AI to guide ad spend + outbound strategy decisions? Why or why not?

Why does AI-generated engagement feel hollow — and is voice training the answer?

Something I've been thinking about since building in this space: the engagement problem with AI content isn't volume, it's recognition.

When someone replies to your post and it reads like "Great insight! Really resonates with me," you know immediately it wasn't them. Not because AI wrote it but because it sounds like no one in particular wrote it.
