## Goodnotes

Goodnotes is a digital note-taking app designed around the feel of writing on paper, then extended with everything a paper notebook cannot do. The core notebook experience uses a low-latency ink engine so handwriting feels natural on a tablet with a stylus. You can rest your hand on the screen, cross out to erase, and convert handwritten text into typed characters when you need something searchable or exportable.

Around that core sits a flexible document workspace. The app handles PDF annotation, typed documents, infinite whiteboards, imported images, and recorded audio in the same environment, so a meeting, lecture, or project space can mix formats without switching tools. Notes and documents sync across iPad, iPhone, Android, Windows, and the web, letting you start a page on a tablet and finish it at a desk.

Goodnotes also layers in AI and collaboration. AI-powered search looks across typed text, handwriting, and sketches at once, and can turn a page of notes into a mind map, a summary, or a project plan with action items. Real-time collaboration, shared notebooks, and education-focused deployments make it a practical fit for students, teachers, and knowledge-heavy teams in fields like architecture, engineering, legal, and consulting.

**Pricing & Plans:** Freemium with a free tier and paid subscription plans, plus separate offerings for education and business. A free trial is available; exact regional prices are listed on the official pricing page.

- **Natural handwriting engine:** Low-latency ink with palm rejection, cross-out to erase, and handwriting-to-text conversion keeps writing close to pen on paper.
- **PDF annotation and markup:** Import contracts, papers, or textbooks and mark them up by hand, with searchable annotations and clean exports.
- **AI search and transformation:** Search across typed text, handwriting, and sketches, and turn notes into summaries, mind maps, or structured plans.
- **Real-time collaboration:** Work together in shared notebooks, documents, and whiteboards simultaneously, without version conflicts or file ping-pong.
- **Cross-device sync:** Continue the same notebook on tablet, phone, desktop, or web so notes follow you between work and study settings.

**Strengths:** Best-in-class handwriting feel makes the transition from paper notebooks easy; Combines notebooks, PDFs, whiteboards, and audio in a single app; AI search reads handwriting and sketches, not just typed text; Broad device support with reliable cross-platform syncing

**Limitations:** The best features sit behind the paid subscription or one-time purchase; Advanced AI and collaboration features require an account and internet connection; Heavy notebooks with large PDFs can be slow on older devices

## OpenFlowKit

OpenFlowKit is an open-source diagramming studio built for engineers who think in systems. It supports three ways of working on one canvas: freehand drawing with shapes, connectors, ink, images and charts; writing the diagram as code in Mermaid, D2 or Structurizr; or letting an AI agent build and edit it live through the Model Context Protocol. Text and canvas stay in sync, so you can start with a snippet and finish with something visual.

A standout v2 feature maps a public GitHub repository directly in the browser: paste an owner/repo URL and OpenFlowKit reads the files, produces boxes and connections, and cites each arrow back to the exact line of code it came from. Private repositories can be mapped locally through the CLI. The result is architecture documentation that reflects the code rather than someone's memory of it.

OpenFlowKit is also practical for day-to-day diagramming: a toolset of 29 MCP tools for agents, C4 context/container/component views that stay connected to one underlying model, automatic matching of 2,000+ cloud and developer icons by node label, animated SVG/GIF/MP4 export, share links and self-hosting. It is MIT licensed, runs locally by default and needs no account.

**Pricing & Plans:** Free and open source under the MIT licence. There is no paid tier on the site; you can start creating without signing up, and the code can be self-hosted.

- **Repo-to-map generation:** Paste a public GitHub repository and OpenFlowKit reads its files in the browser to draw modules and connections, with every arrow cited to the source line it came from.
- **Agent-native canvas over MCP:** 29 diagram tools for Claude Code, Codex, Cursor, VS Code, Windsurf or any MCP client, so an agent can draw on the diagram you have open, one undo away.
- **Diagram as code:** Write or paste Mermaid, D2 or Structurizr; the text and the canvas remain the same diagram, so you can round-trip between syntax and visuals.
- **Connected C4 model views:** Move from system context to containers to components in linked views that all stay grounded in a single architecture model.
- **Icon matching and motion export:** Label a node 'PostgreSQL' or 'Kubernetes' and the right icon is matched automatically from 2,000+ cloud and developer icons; export animated SVG, GIF, MP4 or WebM for living documentation.

**Strengths:** Free, MIT-licensed and local-first with no account required; Unique repo-to-diagram mapping that cites each connection back to code; Works equally well for hand drawing, diagram-as-code and AI-agent workflows; Strong ecosystem coverage with automatic matching of 2,000+ cloud and developer icons

**Limitations:** No hosted paid support or managed cloud option is advertised, so teams self-host; Advanced MCP and CLI repo mapping assumes comfort with developer tooling; C4 model depth and multiple views can feel heavy for quick one-off sketches
