Just shipped a smart guardrail in experiments: if your flow needs test data, it now blocks runs with a friendly prompt and offers one-click AI-generated samples. No more silent all-fail runs! Small details, big peace of mind. #BuildInPublic

Been deep in AI tools this week. Here are 10 that actually earned a spot in my stack: 1. (prompt once, generate with 40+ image/video models) 2. (an AI colleague that works your tickets in Slack) 3. (a blockchain built so AI agents can pay each other) 4. (one API key for 100+ models, auto-routed + insured) 5. (an AI employee that lives in Slack and Teams) 6. (run your fleet of Claude Code/Codex agents in parallel) 7. (AI search that answers instead of just linking) 8. (describe a topic, get a full slide deck back) 9. (speak naturally, get polished text 4x faster) 10. (60+ image/video models, one prompt box) Don't lose this list, it could be incredibly helpful.

I built a kind of paas for llms, the idea was to allow my family deploy webs cheap and easy, my family doesn't use It, but It end being very useful form mento deploy small apps. You can check It out on https://onvibe.run there is a list of forkable apps that I use. I did some kind of meta thing, because bownI can create apps with llm (like Claude) and expose an mcp on theme (like the notes and todolist apps).
