## 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

## sliiidea

sliiidea is a lightweight idea management app with a specific focus: collecting ideas and then evaluating them properly, instead of letting them pile up and fade. The interface is deliberately simple — capture a thought, optionally categorise it, and it immediately joins your evaluation flow.

The distinctive part is how evaluation works. Rather than scoring ideas once and moving on, sliiidea uses a swipe interface similar to popular dating apps: swipe right to upvote, left to downvote. Revisiting ideas regularly and evaluating them the same way builds a more reliable, less mood-dependent basis for deciding which ideas are worth pursuing. You can organise ideas in lists, filter them, track their status and mark the strongest ones as 'to implement' when it's time to choose.

The app is free to use on iOS, Android and the web, with no account required to try it. The developers also list AI features on the roadmap — AI-generated idea lists from a description, AI-augmented ideas mixed into your list, automatic enhancements and feedback, and duplicate detection — which will strengthen the brainstorming side as they ship.

**Pricing & Plans:** Free — sliiidea is free to use on iOS, Android and the web, with no account required to try it.

- **Fast idea capture:** Capture thoughts instantly with a simple interface so nothing is lost; ideas drop straight into your evaluation flow.
- **Swipe to prioritize:** Evaluate ideas like a dating app — swipe right to upvote, left to discard — for repeated, mood-independent judgment.
- **Lists, filters and statuses:** Organize ideas in lists, apply filters and track status, then mark winners as 'to implement' when it's time to decide.
- **Reflection over time:** Come back regularly, add new thoughts and let ideas grow and develop over time rather than stall after capture.
- **AI features on the roadmap:** The roadmap includes AI-generated idea lists, AI-augmented suggestions, automatic feedback and duplicate detection.

**Strengths:** Free to use across iOS, Android and web; Swipe evaluation makes prioritization fast and repeatable; Simple, focused interface avoids feature bloat; Roadmap promises AI-generated ideas and duplicate detection

**Limitations:** AI features (auto idea generation, feedback, duplicate detection) are still listed as upcoming; Focused purely on idea capture and prioritization, not on executing projects; Requires regular revisits to get the most from the evaluation model
