I literally love this, here's my idea: "SkillMate is a micro-learning platform powered by an AI buddy that helps you master practical skills in 5–7 days with short daily tasks and personalized feedback.
Designed for creators, freelancers, and growth-driven professionals, it cuts through information overload with simple, actionable learning paths.
Learn in under 15 minutes a day—no endless courses, no fluff."
@luca_vizzielli ouch
With the ease and pace at which we can build apps with AI, we need this to have less AI-generated-app-noise!
So lets take it to the real world and roast this:
App that links banana stem waste to mushroom growers, geo‑matched
@luisa_lima2 ouch!
A market type of platform where people are able to rent their kids for corporate meetings. Kids often come with fresh ideas, able to unblock even the most dreading meeting discussions! - I'm proud of my 3/100
@adrian_pradzioch you win the lowest score of the day!
Love this @darnocks!
Roast me this - automated contract review based on commercial playbook with guidelines on negotiating wiggle room
so here's an offline idea; gap year for senior executives. get to experience 'play' again and reinvigorate your ambitions for the last 30 years of your life. gap year (or 3-6 months will include serious outdoor activities and personal reflection supported by professionals.

Great product! Loved seeing this come together from musings on a WhatsApp group to fully fledged product.
Here's my SAAS:
A platform where creators/influencers can sign up and talk to an AI assistant, that walks them from start to finish developing a course and community using AI powered image/video/quiz/3d game generation.
There's a community, payments, email nurturing, landing pages and CRM built in so creators don't have to juggle multiple tools.
It's free to start and paid members can clone their voice and likeness so their AI clone can teach their students while they sleep :)
(It's also already being built so hopefully I won't be told it's a bad idea!! haha!)
My response:
This is the SaaS equivalent of a kitchen sink thrown into a blender with every AI buzzword from 2023. You’re pitching an all-in-one creator platform with AI everything—course builder, community, payments, CRM, landing pages, and, for dessert, voice/likeness cloning. The only thing missing is blockchain and a metaverse tie-in. The build complexity here is off the charts: you’re talking months (if not years) to ship a brittle MVP, and every feature is a startup graveyard on its own.
Hilarious! Some actual useful insights from the detailed analysis, however I'm pleased to say I've already shipped an MVP and more :)
