Name three things from the last business book you read.

Most people can't. ThinkerNotes keeps what you actually took from each book, podcast, customer call and mistake, in your own words, and brings it back the moment it's relevant again.

People don't buy the cheapest option. They buy the one they can most easily justify.

You're learning faster than you've ever learned. But you're forgetting it even faster.

Running a business is one long crash course. A book on pricing, a podcast on hiring, a call with a customer who explains exactly why they churned, a launch that goes sideways and teaches you something you swore you'd never forget.

Three months later you can name the book and not much else.

Every model has read the same books. None of them has your notes.

Generic knowledge is free now, and infinite. Any model will hand you a competent summary of anything you ask it.

The same sentence means different things to different people. It means something different to you now than it did two years ago. What you take from a book depends entirely on what you already have in your head.

We're not giving you AI notes. We find your own.

How it works

1

Get it down while it's fresh

A draft. One line, however it comes out. No title, no folder, nothing to decide.

2

Come back and sharpen it

Turn the draft into an insight. Add the context, cut it to the point you actually want to make. This is the part that makes it yours, and it takes a minute.

3

Find what it connects to

We show you the older notes it relates to. You link the ones that genuinely belong, and the link stays.

This is not a new idea. It’s just never been practical.

Niklas Luhmann was a sociologist with a wooden box of index cards. Every card held one idea in his own words, linked by hand to the cards it related to. Over thirty years he published more than 70 books, and he credited the box rather than himself.

He never claimed to remember what was in it. That was the point of having it. He described the box as a second memory, something he could have a conversation with, because his own memory couldn't hold thirty years of reading.

What it cost him was the filing. Deciding where each card went, and hunting down the ones it connected to, by hand, for decades.

That part is now automatic. The writing stays yours.

The note you forgot you wrote, back when it matters

Storage is easy. Remembering to look is the part nobody does. ThinkerNotes brings old ideas back to you in context, so the thinking you did last year shows up in the decision you're making this week.

Working on Momentum is far easier to keep than it is to create.

Consistency is a distribution strategy. Showing up weekly beats one perfect launch.

From thought to saved in one sentence

A realisation after a sales call. A line from a podcast that reframed something. Write it as you'd say it out loud. No title, no folder, no structure to maintain.

Find the thing you can only half remember

Describe the shape of the idea and the note comes back, even when you can't recall a word of how you wrote it.

Every source, still attached to what you learned from it

Books, podcasts, newsletters, articles. Import your Kindle highlights and turn them into ideas that sit next to where they came from.

Your notes, in whatever you already use

ThinkerNotes connects over MCP, so Claude or any other agent can search your insights directly. Ask about pricing and it hands back what you concluded, in your own words, not a generic answer pulled from the internet.

The model only ever gets to read what you've already written, never to add to it.

Reasonable doubts

“I already have Notion or Obsidian.”

So did we. Filing cabinets are excellent at storing and terrible at reminding. The question isn't where your notes live. It's whether any of them have come back to you unprompted in the last six months.

“Isn't this just AI doing my thinking for me?”

The opposite. ThinkerNotes never writes in your voice and never turns your ideas into content. It finds the connections and hands them to you. Deciding what they mean is the whole point, and it stays yours.

“I'll never keep it up.”

You won't have to maintain anything. There's no structure to design, no tagging system to invent, no weekly review to skip. One sentence when you learn something is the entire commitment.

What you work out should stay worked out.

You're going to learn something valuable this week. The only question is whether you still have it in March.
