Hi everyone, I’m Martijn 👋 I built ChatStash after getting frustrated that AI platforms don’t let us truly own our conversations. Every answer you get from ChatGPT or Claude lives on their servers. ChatStash runs quietly in your browser, automatically saving everything you write and receive. It’s 100% local, private, and simple. We use it internally to keep technical Q&A, code snippets, and...

Hey ProductHunt! 👋 I'm excited to share Deep Work Streaks with you all today. This started as a personal tool I built for myself after getting frustrated with existing productivity apps—they were either too complex or missing that satisfying streak element that keeps you motivated. As someone who's struggled with focus (like many of us!), I wanted something simple that combined the dopamine hit...

👋 Hi there Hunters, I’m excited to share Bluesky Keywords with you! Tracking conversations on Bluesky can be tough, so I built Bluesky Keywords to make it simple. It helps you monitor keywords, track mentions, and get real-time alerts or daily digests—so you can jump into conversations that matter. One of the early users shared this: "I landed my first customers by responding to posts I found...

Hey Product Hunt! 👋 I'm thrilled to introduce WhatPulse Profiles - a game-changer in personal productivity tracking. WhatPulse has always been about understanding your digital habits, but with Profiles, we're taking it to the next level. Now you can create separate profiles for different activities, giving you unprecedented insight into how you use your computer across various aspects of your...

Hi everyone 👋 I'm a big fan of TailwindCSS, and use it for every new project I build. Recently, I've wanted to make it easier to create responsive designs and get a grip on the Tailwind breakpoints (xs, sm, md, etc.) while doing so. There were a few solutions out there, but they either had to be integrated into the app codebase, or if it was a browser extension where I had to remember the width...

👋 Hey ProductHunt community, I'm excited to introduce TypeTest.io - a fresh take on improving typing skills for everyone, from casual typists to coding wizards! 🎉 As a developer and writer, I found that most typing tools were either too generic or too focused on speed alone and focused on single sessions. I wanted something more - something that I could use to keep track of my progress and add...

Hi ProductHunt 👋 While we're waiting on OpenAI to release a marketplace for GPTs, I decided to build a directory to list and find cool GPTs. There's some awesome GPTs out there already! It'll automatically update when Google indexes new public GPTs, so there's no submit process. Just create a new GPT marked as public - and the directory will pick it up!

Congrats! I think you have a leg up on other directories that just post a link and the product summary. Having deeper reviews like you have makes all the difference 😊

👋 Hey ProductHunt, I'm excited to be back with a new tool for all the AI enthusiasts! As someone who's built a few AI products integrating with OpenAI, I want to keep track of my API costs and identify any instances of abuse or runaway apps. There are tools where you can go and put in an API key to see your usage - but I wanted passive monitoring. So, I built AI Spend - an intelligent...

Hi everyone 👋 I'm Martijn, and I am thrilled to share DeckAssistant for Stream Deck with you! As a maker, content creator, and writer, I was constantly copy-pasting content between different apps and ChatGPT. There had to be a better way, so I built an AI-powered Stream Deck plugin that streamlines my workflow and removes a context switch between apps. With DeckAssistant, you can easily select...
