## 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

## tabOS

tabOS is a Chrome extension that reframes your browser's new tab as a small operating system for your work. Rather than being a one-trick tab manager, it bundles tab and group management with documents, notes, feeds and AI into a single surface. You install it from the Chrome Web Store, and from then on every new tab is a dashboard where you lay your open work out in the open instead of hunting through a strip of tabs.

The tab management layer is thorough: drag and drop to save or close tabs and groups, create and rearrange groups, layer groups into folders, discard tabs to free memory, pin and move tabs, and view everything in grid, column, list or tree layouts. Alongside it sits a real productivity stack — create documents with Markdown and syntax highlighting, take quick notes, run to-do lists and store code snippets and images, all without leaving the browser. There is also a feeds section for RSS, YouTube and Reddit.

The AI side is where tabOS leans into the ChatGPT branding. You can assemble custom-prompted AI helpers, chat with AI, use Vision AI for image recognition, and select among ChatGPT 3.5, 4.0 and Turbo. A sharing and collaboration layer supports shared folders, shared documents and live sessions, with global, open-tab and fuzzy search to find anything across tabs, bookmarks and cloud files. Pricing is freemium: a Free Plan covers the core, while Pro and AI Plus plans add extra cloud storage, AI sorting and automatic daily backups. It is developed by Aconiti interfaces AB, the same independent studio behind tabExtend, and is not an official Google product.

**Pricing & Plans:** tabOS uses a freemium model with in-app purchases. The Free Plan unlocks the core workspace features and can be started with an anonymous account. Pro and AI Plus plans add extra cloud storage, AI sorting capabilities and automatic daily backups; exact prices are shown in the Chrome Web Store and in-app.

- **Tab and group management:** Manage tabs and tab groups, drag and drop to save or close them, discard tabs to free resources, and organise everything in grid, column, list and tree views.
- **Documents and notes:** Create and edit documents, take notes, manage to-dos, store code snippets and use Markdown with syntax highlighting directly in the new tab.
- **AI helpers and assistants:** Assemble custom-prompted AI helpers, chat with AI, use Vision AI for image recognition and choose among ChatGPT 3.5, 4.0 and Turbo models.
- **RSS, YouTube and Reddit feeds:** Create and subscribe to RSS feeds, and follow YouTube and Reddit feeds, all from inside your new tab.
- **Search and organisation:** Search across tabs, bookmarks and cloud files with global, open-tab and fuzzy search, and keep data safe with automatic daily backups on paid plans.

**Strengths:** Combines tab management, documents, notes, feeds and AI in one surface; Solid tab workflow with groups, folders, discarding and multiple view layouts; Free Plan covers the essentials, with paid tiers for storage and AI sorting; Includes collaboration features like shared folders and documents

**Limitations:** Pro and AI Plus tiers are needed for extra cloud storage and AI sorting capabilities; It is a full workspace system, so there is more to learn than a simple tab-grouping add-on; AI features depend on the ChatGPT models the extension exposes, whose availability and behaviour can change
