I'm Tom, the cofounder of Canonical AI. I build a Voice AI agent that interviews you, then writes LinkedIn and X posts based on the interview. ### Why did I build this? 1. LinkedIn and X are b2b lead goldmines. But generating content is hard. You have to figure out what to say. If you're like me, you have trouble coming up with social post ideas when staring at a blank screen. But interesting ideas arrive when I step away from my laptop and talk to people. Also, it's hard to compose the content in a way that appeases the platform algorithms. 2. I want to dogfood my product. We’re building…

OmnyChat▲7Hey all, During Christmas and new year I was building this app day and night, I basically built it for my own use, I've got so much headache switching between tabs of different LLMs and chatbots, and other ai chat apps were missing some features that I really really wanted: - be able to chat with multiple models at once - be able to do debate with multiple models so thats why I built it, I launched it 2 days ago, 0 users so far, I really appreciate any feedbacks. I offer free plan with 20 message / day in some cheap models (I'm indie dev with no budget) and 2 plans that gives you higher…

Hi HN, I created a (realistic) fake tweet generator to make my mum believe I'm successful until I get there for real haha. Now I can proudly (not) show her Elon endorsed my SaaS! It's 100% free to use and I tried to make it as realistic as possible while being easy to use. There are already existing similar tools but I could not find one that automatically pre-fills data from a twitter username and that handles business accounts (square picture/gold badge/company picture) so I built it. I would love to hear your feedback or suggestions!

I've been experimenting with ways to increase AI adoption for non-technical people. Basically, all companies are pushing for AI because it's all over the news and they feel left behind but most people have no clue where to start. I think 90% of people (ie non coders) are sufficiently well served by using cowork instead of claude code or something similar. If we can get people from sales, customer support, marketing, etc to collaborate with skills and cowork to form a company brain, I think it's gold. So I think there's opportunity for the community to share skills that work well for 1000s of…

This is the first version of an app idea I had last month as a way to dip my toes into some of the AI APIs. The idea is you can record yourself answering and rehearsing what you'll say to common interview questions, and receive AI feedback on how you did and how you can improve. In the future I may expand into other subject areas, but wanted to scope it to the behavioral interview format for the time being. Super open to feedback and suggestions!

Hey everyone! I wanted to share a tool I built to help you quickly find potential customers across social media for your product. It's a really simple concept: you simply paste in your landing page URL, and it shows you highly relevant posts across Reddit (Working to integrate few more) from people who likely need your product or service. For example, if you have a minimal to-do list app, it will show you posts like "Anyone know of a minimal to-do list app?" or "Really starting to dislike how complex Notion is." These posts are from the last 48 hours, updated in real-time, and uniquely…

Hey folks, I'm Yuval. I run a tiny startup called Glitter AI. It's just me full-time here, with a couple of freelances to help here and there. A couple of months ago, I went from managing zero requests to hundreds -- overnight (won Product of the day on Product Hunt). As someone who gets VERY easily distracted (maybe you relate), I had to find some sort of way of handling all the chaos if I didn't want to burn out. I came up with a pretty cool automation flow that I thought folks on HN here may be interested in reading about :) So here goes: Most of my interactions come through Intercom.…

Hey HN I built a free AI SEO app called seoby.ai. I'm launching it on ProductHunt, Reddit and a few other places on Monday (19th February). It's 100% free, and has some pretty neat tools: 1.

AI Outline Generator: Remove writer's block and generate SEO-friendly outlines for your articles, blog posts, and landing pages. 3. AI SEO Topic Cluster Generator: Generate SEO-optimized topic clusters for your website and get better search engine visibility. I would love feedback/ideas/suggestions of…

I built a tool to solve a problem I kept running into: I was making product decisions based on guessing instead of real users. I kept building stuff nobody wanted as I was usually wrong. So, I built HolyShift: AI agents that validate product ideas by talking to real people on Reddit, HN, X, and LinkedIn … then generate a detailed GTM and “Should we build this?” report. No synthetic data (ChatGPT). No predictions. Only real conversations from real people. What it does • Posts platform-native questions (where allowed) • Collects real reactions, objections, pricing signals • Clusters feedback…

Excited to share something I've been building recently called ReplyGuy. I made it to solve a personal pain with a SaaS product I built, which was that we were always monitoring Reddit and Twitter to see if anyone had mentioned keywords indicating they were looking for us. Before, we had to go manually respond to posts, often missing good mention opportunities. Would love for HN folks to try it and let me know what you think!

So I've been obsessed with a weird question for the past 6 months, what happens to SEO when everyone starts asking ChatGPT for recommendations instead of Googling? The answer, apparently, is chaos. And maybe opportunity? I built FirstClick because I noticed something strange. My previous startup was getting zero traffic from AI assistants, but our competitor (objectively worse product, sorry not sorry) was getting mentioned by Claude and Perplexity constantly. It drove me crazy. So I reverse engineered why. Turns out there's a whole new game being played and most founders don't even know it…

Hey HN,I'm Arthur, solo founder here. After struggling to get consistent traffic for my own startup, I realized I was spending more time guessing how to market than actually building.

It covers: – Where and how to post on Reddit without getting banned – What to tweet to get engagement as a SaaS founder – How to grow LinkedIn with cold DMs and soft content Since launching, I’ve gotten 15k+ visitors and $5.7k…
