## ThinkerNotes

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.

- **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.

**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

**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

## UBBLU

UBBLU is built around a simple promise: search less, create more. Rather than treating notes as a filing cabinet you have to sort and remember, it treats them as a memory you can query. You capture ideas, inspirations, meeting notes, and key facts on the way in, and let the app handle recall on the way out.

The structure is deliberately lightweight. Quick Notes capture fleeting thoughts, while Cards hold longer, more developed ideas and build into a richer knowledge base. Tags link and categorize notes and cards so related material stays connected, and folders, pins, and reminders keep the things you use most within reach. The headline feature is 'Ask', which spans notes, cards, folders, and tags: you pose a question and UBBLU brings back the relevant information instantly, so you never have to hunt for where you filed something.

UBBLU also reaches beyond what you type. You can upload documents, ask questions about their contents, and save the insights back as notes. Grouping content under a tag lets UBBLU generate detailed answers and surface insights from the connected material. It is designed for thinkers who value creation over searching - the company's own framing. Sign-up is free with no credit card required. Note that UBBLU currently describes itself as desktop-only, with a mobile version announced as coming soon, so check device support before committing.

**Pricing & Plans:** Free. UBBLU offers free sign-up with no credit card required for its core AI-driven note-taking and retrieval experience.

- **Ask search across everything:** Ask a question in plain language and UBBLU pulls the answer from across your notes, cards, folders, and tags instead of making you scroll.
- **Notes and structured cards:** Capture fleeting thoughts as quick notes and develop longer ideas as structured Cards that build into a knowledge base.
- **Tags, folders, pins, and reminders:** Organize with tags and folders, pin the items you use most, and set reminders so deadlines and follow-ups do not slip.
- **Connected discovery and insights:** UBBLU links related concepts and generates detailed answers and insights from the content grouped under a tag.
- **Uploaded document interaction:** Upload documents, ask questions about them, and store the answers as notes for later retrieval.

**Strengths:** Ask-based retrieval removes the need to remember where notes are filed; Lightweight structure of notes, cards, and tags is quick to adopt; Document upload with Q&A extends it beyond typed notes; Free to sign up with no credit card required

**Limitations:** Currently desktop-only, with the mobile app still listed as coming soon; The public site is fairly minimal, so some details require signing up to see; Positioned as a newer product, so the ecosystem of integrations has room to grow; Note-taking habits are personal, and switching tools has a real learning curve
