Garry Tan's Golden Shadow – Save Your Startup AI Coach

Hi HN, We built Shadow, a real-time meeting assistant that listens to your call and surfaces useful prompts while you’re speaking. The idea came from a simple observation: during important conversations (sales calls, founder meetings, interviews) you often realize the best question or insight 5 minutes too late. Shadow tries to solve that by acting like a quiet wingman during the call. What it does right now: • Tracks agenda topics so conversations don’t drift • Suggests follow-up questions based on what’s being said • Surfaces useful facts or angles in real time This is still an early MVP…

Hey guys well basically…yeah…I hate GoogleNoteLLM and other AI YouTube Summarizers. They feel meh…boring. I actually like youlearn.ai but it’s built for students. So, as a builder.

Over the past year, I’ve been building a deeply personal project called Eiren AI — a mindfulness and growth app designed to help people reduce overwhelm, stay grounded, and make daily progress toward their goals.

Eiren AI helps users: -Turn visions into structured goals and daily tasks with AI support. -Reflect through journaling (with templates + AI autocomplete). -Generate…

They are claiming to have 1M+ users with just one feature which is to convert your learning material into summaries, quizzes etc. I gave this a shot and cloned almost most of the features in just 9+ hours of continous vibe coding (with 20% manual though). Now I'm selling this on mvp marketplace. Might probably open source it in future or give it free.
