... principles. The success criteria. Then let AI do the few things it's actually better at rapid iteration, spotting patterns you missed, exploring variations fast. But there's always something I keep for myself. The line in the sand. For me, it's the "why." I won't let AI define why something matters or who it's for. That clarity has to come from real judgment, from understanding your users or your own convictions. Everything else can be negotiable ...

... tools we simply can t imagine our day without. If I had to pick a few AI tools that have become part of my daily workflow, these would be: ChatGPT + Claude summarising and improving text (and Codex in VS Code for coding) Grammarly AI correcting and improving my English Figma with its AI prompting helps me a lot with improving my graphic design ideas Google Gemini for note-taking from Google Meet, plus AI features in Google Sheets and Docs ... ... transcription for meeting notes. What actually changed my work is not any single tool, it is that I stopped keeping a mental list of which writing was worth doing myself. Grammarly I use less and less though, it keeps sanding

... ruling this June, plus the oversight board (PCLOB) losing quorum, have weakened the exact safeguards the framework was built on. A "Schrems III" case is widely expected. If you plan a product roadmap around that, you're building on sand. So European teams end up doing what we did: EU-only hosting, on-device processing, avoiding the strongest US models on purpose. Sometimes that's better engineering. Sometimes it just means shipping a weaker product for reasons that have nothing ...

... Aravindh, founder of DotSpark. The problem: the better AI got, the less my output sounded like me. Every answer came back polished but generic the median take anyone would get. My reasoning, my analogies, my angle, all sanded off. DotSpark fixes that. It maps how you think and feeds it into Claude, ChatGPT, Gemini, and Perplexity via an MCP server, so your AI reasons the way you do. Three pieces: ThinQer Index free, 60 seconds. Reads your AI chat history ...

... never trust to automation? For fellow founders: we're holding ourselves to a "First Blood" milestone one deterministically validated vuln on a live authorized program before we open funding conversations. Smart line in the sand, or over-engineering the proof? Open question: where does "autonomous" stop being a feature and start being a liability in security tooling? Drop a comment I'll reply to every one and share what we learn along the way. Roast the idea, poke holes ...

... teams that failed were not the ones with bad code. They were the ones with no visibility into how bad the code was. What is the first signal you look for that tells you a team is building on sand? Comment from Imed Radhouani(@imed_radhouani): @tijogaucher  That is the trap. "After PMF" sounds responsible. Like you are focusing on what matters. But PMF is not a destination you hit and then pause to fix the foundation ... ... spent 6 months paying for shortcuts you took in the first 6 weeks. The cost breakdown is not about the money. It is about the lost features you never got to build. The customers you never acquired. The competitors

... used to love playing Falling Sand, so I built my own version you can play right in your browser. I added weather effects, chain reactions, and synth style sound effects to make it feel a little fresh while keeping the same chaotic fun that made the original so addictive. Would love any feedback on the gameplay, effects, and overall feel. What would you add next? https://brzzy.co/falling-sand-game Comment from James Haver(@mchaver): It was a little awkward playing ...

... evolves based on real usage. Comment from Derek Cheng(@derekattonkotsu): @build_with_aj  thanks for the thoughts! Regarding things that are not obvious, can you share an example or two? We're eager to sand down the rough edges. Let us know what you find once you settle on your first project! Excited to see the results. Comment from AJ(@build_with_aj): Tempted to build an agentic coding harness. dw it won't be a competitor

... adopted, your name goes into the Authors section. Add your name, email, and (optional) product link you ll be listed as a Signatory. This isn t marketing fluff. It s a declaration. A line in the sand for how we build as indie founders. Would love your thoughts and if you d be proud to sign it alongside ...

... internal/external database or run across internet, Lan/wan network. I also share my app with others to test and review which provides valuable feedback to improve later. I also test my prototypes in a real world environment not in some sand box virtual environment or IDE so i can then move to production stages. Testing and security is paramount to account for any and all possibilities that could create application errors, crashes, etc. making for a bad user experience which results ... ... assist me in various stages of development including code completion, bugs or overcoming other complexities. I learn from this as well and makes me better at what i want/need to accomplish now and on future projects. I use VS

... best situation is get the name out there a little more because it takes many, many times of hearing of a tool to become a sale. We decided based on having a line in the sand within a month also had to consider holidays and weekends. We decided also on being able to have a milestone in the month ahead. Theres always got to be another feedback and improvement line to run to, this is just another line ... ... that space is part of the job. Then always prioritise what to build next in short sprints (2 weks) and keep focused. Think about what s most valuable to users and the business, then prioritise based on effort vs

... project was a todo webapp classic entry point But the one I'm most proud of came later: Claudine , a kanban board for Claude Code. Built it because I kept losing track of which agent conversations needed my attention vs. which were still running. Tool used: Claude Code itself (meta, I know) Most difficult part: Auto-detecting conversation status from raw JSONL files inferring "is this waiting for me?" is surprisingly tricky Earned money? Not directly it's free ... ... refactor it from procedural code to a state machine architecture cleaner logic for handling market conditions. But back then it was the ancient era of AI coding: copy code paste into ChatGPT copy the response paste back into VS

... setting personal goals for myself to make and else as many SaaS apps this year as possible. I'm going to launch technically my second of the year, in about a week on product hunt, I'm just sanding out the edges and trying my best to not add any more features before launch haha. It's an AI spritesheet maker! I noticed that the newest image generation models could do pretty good at creating spritesheets, but I often wanted ...

... Prompt A + Model B = Output C... Until it suddenly doesn't. Same input. Same config. Totally different output. Because LLMs aren t deterministic and when your product depends on stable responses, it feels like building on sand. I got tired of playing prompt roulette. Tired of: Copy-pasting prompts into playgrounds Switching models manually Changing temperature settings Scoring responses by eye Losing track of what worked and what didn t So I built PromptPerf A fast, focused prompt testing playground ...

... Rahul Vohra(@rahulvohra): @rajiv_ayyangar  Thanks Rajiv, and you're totally right this is a very ambitious set of features! So this launch isn't a "one and done". It's more like drawing a line in the sand and saying: we're going to keep making these better from here Comment from Rahul Vohra(@rahulvohra): @randomor  aww thank you!! others sometimes do get there first, but I am confident that we always end up with the best ...
