No More Circling Back
Smart glasses · a second brain

Close itnow.

Glasses that listen with you, know what you know, and answer before the moment passes. So every conversation ends with a decision and an owner.

The problem

Every conversation breaks in the same six places.

Three when you listen. Three when you talk. Miss one and the conversation starts over a week later, in a new meeting, with the same people. Tap a step.

And then someone says “let’s circle back.”

Who it’s for

One pair of glasses. Three modes. Three levels.

A student, a new hire and someone walking into a reception need different help. Each mode comes with its own recipes: one-tap prompts that run on the last few minutes of conversation. The recipes change with how much you already know, and you can write your own.

Try it

It all lives on one ring.

The conversation below is running now. Use the ring the way you would on your finger: tap, double tap, swipe, press and hold. Or use the list.

How it helps

It speaks up. You ask. Your notes are one gesture away.

Proactive nudge

When it matters, then gone.

Numbers disagree: they said 18% churn. Your Sep 3 notes say 14%.

It watches every turn of speech for the few moments worth interrupting: a term you won’t know, a number that contradicts your notes, a task nobody owns. Then it closes itself.

What you ask for stays.

Two lemonade stands merge. Saving on lemons usually happens. Selling twice as much usually doesn’t.

Swipe up for your recipes. Tap for a quick answer. An answer you asked for stays on the lens until you double tap it away, because you wanted the substance.

Tap and hold opens the menu. Notes holds the pre-read, what you saved with a long press, and what you promised whom. Nobody sees you check.

The second brain

It was in the room. Every room.

Every conversation, class and document becomes part of one brain: people, projects, courses and ideas as linked pages. During the day it’s the context behind every answer. At night, it dreams.

Day · listening · 14 conversations so far
100+MBA materials: syllabi, cases, slides, readings
200slides of the strategy deck you built at work
Everyconversation, transcribed and linked to who was there
Inboxemail and calendar, so it knows what’s next
  1. Sorts the day’s conversations into people, projects and courses
  2. Merges new facts, flags anything that contradicts what it knew
  3. Writes tomorrow’s pre-reads for every class and meeting
  4. Pulls the news you’ll want before your first conversation

Imagine privacy were solved. You’d have an expert on your own life, in your eye.

An agent that has read all 200 slides you made at work and all 100 documents from the MBA. It correlates a lecture with your job and tells you why this topic matters to you, right when it comes up.

Today’s synergy haircut is the same math as the cross-sell uplift in your pricing deck (slide 47). The deck assumes 12%. This professor would cut it to 6%, and your payback moves out a year.

Where it comes from

Built on four things I couldn’t stop using.

Granola

Ask questions of a meeting’s transcript. I want that live, on your face, with your whole life as context and the courage to speak first.

ChatGPT Voice

Snappy, natural, genuinely useful. It set the bar for how fast and human help should feel.

GBrain

Garry Tan’s second brain: every person, company and idea as a page the AI can read and keep current.

Retrieval

Knowledge graphs, RAG, Qdrant, embeddings. Many ways to pull the one right fact in the second you need it.

Onboarding

The setup is a conversation.

A voice agent asks you a handful of questions, connects your email and calendar, and draws an accurate map of who you are: your priorities, your people, your work. The easiest onboarding a second brain has ever had.

The engine

Generative AI runs every part of it. Day and night.

While you talk

Inference, every turn of speech.

  • Decides, proactively, whether this moment deserves a nudge
  • Runs your recipes on the last minutes of transcript
  • Answers from your brain, preloaded when the session starts
While you sleep

A nightly cycle.

  • Organizes everything learned that day into the brain
  • Writes the pre-reads for tomorrow
  • Scrapes the news worth reading at breakfast

What success looks like

A beginner holds their own in a room of experts.

An expert sees the edge case first.

The more you use it, the less you need it.

Nobody says “let’s circle back.”

Weigh in

Help me build it. What would you use?

Anonymous. Everyone who opens this page sees the results as they come in.

Where would you use it first?

Would you use recipes other people wrote?

A shelf of prompts, shared or sold, like an app store for questions.

Which recipes would you actually use?
