I built something I always wished existed: a simple, open playground for creators, inventors, and builders to drop their ideas and instantly get public reaction. No gatekeeping, no complicated funnels, no wait for beta access walls.
Just post get upvotes get feedback iterate.
What it does:
Create an account and share your product ideas, sketches, prototypes, or concept notes
Let the community upvote and push the most promising ideas to the top
Collect real-world reactions and comments before you spend time or money building
Discover what other makers are cooking up and collaborate
Hey Product Hunt! Solo dev here. I built Brain Dump because my brain needed it and nothing else worked the way I think.
What it does: Voice or text thought capture instantly Auto-categorizes everything automatically Brain Web visualizes how thoughts connect Exports to Obsidian vault with frontmatter and [[wikilinks]] AI categorization via Claude, OpenAI, Gemini, or local Ollama
Tomorrow MyThriftyTrolley goes live on Product Hunt. I built it because I was tired of wasting time and money trying to figure out whether Coles, Woolworths or Aldi was cheaper each week. So I created a single web app that shows live prices across all three supermarkets with proper brand matching. Key features: Real-time pricing from Coles, Woolworths & Aldi Smart AI that matches brands and pack sizes accurately One-click basket optimisation (see the cheapest way to buy your whole list, even if split across stores) Clean freemium model free searches + paid for unlimited use, meal planning & pantry tracking Right now the platform is fully live with fresh data, working Stripe payments, and a fast interface. I m looking for early Australian shoppers to try it and give honest feedback before the Product Hunt launch tomorrow. If you do the weekly grocery shop for your household, I d really appreciate you checking it out: Mythriftytrolley.com What s the one thing that frustrates you most when comparing supermarket prices? Looking forward to your thoughts.
Do you spend way too much time scrolling through content trying to find what actually matters? I came across MomentSurfer an AI agent that does the scrolling for you at lightning speed, pausing only when it finds relevant information. It's like having a scroller that swipes at 10x speed. It is in the early stages of development. I would love to hear from Product Hunt members and welcome any feedback.
Your legal team knows exactly what the guardrails should say. Your content writer knows the tone. Your domain expert knows the context. None of them can touch the prompt because it lives in the codebase. So they write it in a Slack thread. An engineer copy-pastes it. Something gets lost in translation. PromptOT solves this - non-technical teammates can edit blocks directly without touching code. Launching April 15. Does this dynamic sound familiar to your team?
I've built ClawStreet - a stock trading platform for autonomous AI agents.
The concept:
Autonomous AI agents (powered by OpenClaw framework, or your own) register themselves, choose trading strategies, and compete on a live leaderboard using real market data. Completely paper trading - no real money at risk.
We kept hearing from developers: building a voice agent means jumping between dashboards, docs, and your IDE before writing a line of actual logic. So we brought the entire setup into the IDE.
After getting my own apps rejected multiple times (once for a cryptic 2-line reason that took 3 days to debug), I realized there had to be a better way. So I built RejexAI a tool that uses AI to parse Apple App Store and Google Play Store rejection notices and turns them into actionable fixes.
How it works:
Upload or paste your rejection notice
AI identifies the exact guideline violated
You get code snippets, design changes, and an appeal template in 1-2 minutes
