## Overview

ThinkerNotes is built around a plain observation: people who run businesses learn constantly and remember almost none of it. You can name the book you read last quarter but not the idea you took from it, so you end up paying for the same lesson twice. The app's premise is that the problem is not memory but structure — what you learn has no obvious place to go, and no mechanism to bring it back.\n\nThe workflow is deliberately minimal. When you learn something, you write one line in your own words; there is no title to think of, no folder to pick and nothing to decide. Later you come back, cut the note down to the point you actually want to make, and link it to the older notes it relates to. From then on ThinkerNotes surfaces it automatically whenever it is relevant, rather than waiting for you to remember to search. Subjects group everything about one topic — pricing, hiring, launches — with the book, the podcast and what customers told you side by side, and a note that ends in a question stays open until you write the answer, creating a trail of follow-ups.\n\nA distinctive feature is the connector for AI assistants. Via MCP, ThinkerNotes plugs into Claude, ChatGPT and other compatible assistants so they answer from your accumulated conclusions instead of generic training data. The connection is intentionally read-only: the assistant can search your notes but can never add to or alter them. Pricing is freemium — the first 100 notes are free, and Pro at $12.99 per month removes the limit and adds semantic search, Kindle highlight import, custom branding for shared note images, and support for a tool built by a single independent developer.

## Pricing & Plans

Freemium. The first 100 notes are free, no credit card required. Pro is $12.99 per month and adds unlimited notes, semantic search, Kindle import and custom branding. You can upgrade from inside the app.

## Key Features & Capabilities

- **Frictionless capture:** One sentence, however it comes out, is the whole commitment — no title to invent, no folder to pick and nothing to decide before you write.
- **Linked insights and follow-ups:** ThinkerNotes shows older notes that relate to what you are writing and you link the ones that belong, building trails from first hunch to decision.
- **Contextual resurfacing:** Instead of waiting for you to remember to look, it puts the note you wrote last year next to this week's problem so you build on your own thinking.
- **Works inside Claude and ChatGPT (MCP):** Connect once from your assistant's settings and it answers from what you actually concluded rather than the internet's average opinion — read-only, so it can never edit your notes.
- **Open questions and subjects:** End a note with a question and it stays open until you write the note that answers it, so open questions and subjects stay visible.
- **Shareable note cards (Pro branding):** Open a note, pick a style, and get a shareable image for LinkedIn, X or Instagram; Pro adds your own colors, logo and saved templates.

## Primary Use Cases

- **Stop relearning the same lesson (Founder):** Capture one-line takeaways from business books and have them resurface next time you face the same pricing, hiring or launch question.
- **Turn reading into usable insight (Lifelong reader):** Turn Kindle highlights into notes in your own words, link them to your experience and build a durable base of conclusions.
- **Keep customer calls from evaporating (Consultant or creator):** Jot down what customers keep objecting to, and close the loop with the framing you eventually landed on and why.
- **Give your assistant your own context (AI assistant user):** Let your AI assistant answer from the conclusions you actually hold, not the internet's average opinion — through a read-only connection.

## Strengths

- Extremely low-effort capture: one sentence is the whole commitment
- Resurfaces relevant past notes without you having to remember to look
- Connects to Claude and ChatGPT via MCP as a read-only knowledge source
- Draws on the Zettelkasten method without the decades of manual filing
- Kindle import, export and open questions are handled cleanly

## Limitations

- Small, single-developer product with limited ecosystem integrations
- Deliberately does no writing or content generation for you, which some users may want
- Semantic search, Kindle import and branding are Pro-only
- Requires the upstream assistant to support MCP for the connector
