## Flexnote

Flexnote organizes notes as cards placed freely on an infinite canvas rather than in a linear document. You can zoom, drag, and rearrange them, or view the same board as a mind map, while typing @ creates bidirectional links that turn loose cards into a connected knowledge network. A tag-based database view lets the same cards double as a task list, book library, or web-clipper archive.

Annotation is a core workflow. PDFs and videos can be dropped onto the canvas to highlight, comment, and generate linked knowledge cards; video annotations support timestamped notes from major platforms, so a quote in a lecture links straight back to the moment it came from. Sharing is one click — any canvas becomes an interactive webpage with optional password protection and no account needed for viewers.

Unlike cloud-first tools, Flexnote stores files on your device by default and is fully usable offline. For multi-device work you connect your own storage via WebDAV, Amazon S3, OneDrive, or Baidu Netdisk, and credentials stay under your control. Flexnote AI runs semantic search and knowledge-base Q&A over your notes; chat uses your own model API key, and index points are bundled with Pro plans. A custom rendering engine keeps panning and editing smooth even at 10,000+ nodes.

**Pricing & Plans:** Flexnote has a free plan with 3 whiteboards, 100 cards, core canvas features, and local storage. Pro and Lifetime plans unlock unlimited whiteboards, Flexnote AI smart-index points, and optional cloud sync; during promotional periods a Lifetime license has been offered at a discounted price. See the pricing page for current plans and point quotas.

- **Infinite canvas with mind maps:** Place cards anywhere on the canvas, then switch to mind-map or database views to see structure without reorganizing your notes.
- **PDF and video annotation:** Highlight and annotate PDFs on the canvas and take timestamped notes on videos; highlights automatically become reference cards.
- **Knowledge-base AI:** Semantic search, knowledge-base Q&A, and content retrieval find the right notes; chat works with your own model API key.
- **Local-first with your own cloud:** Files live on your device by default and sync across devices through WebDAV, S3, OneDrive, or Baidu Netdisk — your credentials stay yours.
- **Publish to the web:** Turn any canvas into an interactive webpage with a single link, with optional password protection and no account required for viewers.

**Strengths:** Local-first storage means notes stay on your device and work offline; Combines infinite canvas, mind maps, and databases instead of splitting tools; PDF and video annotation with automatic reference cards is rare in note apps; Sync uses your own WebDAV, S3, or OneDrive accounts, so you keep control of data

**Limitations:** The full web app is not finished; online access is view-only so far; Flexnote AI smart-index points are billed separately from AI chat usage; Advanced publishing and AI features sit behind the Pro or Lifetime tiers

## 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
