## 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

## Idlen

Idlen targets the dead time built into AI-assisted work. Whenever a model is generating code or text, the user waits a few seconds staring at a spinner. Idlen fills that window with a small native ad for a developer tool and shares the resulting revenue with the person who saw it. Developers install an extension for VS Code, Cursor, Windsurf, a Chromium browser, or Firefox, then keep working normally; earnings accumulate in an account and can be withdrawn through Stripe or PayPal, or converted into API credits at a bonus rate.

For advertisers, Idlen sells access to that developer attention with technology-stack targeting rather than cookie-based tracking. Campaigns can be aimed at audiences defined by what their code actually imports — React, Python, AWS, or Kubernetes, for example — which Idlen determines by analyzing package.json locally on the user's machine and sending only anonymous keyword tags to its ad server. Budget controls, a second-price auction model, and real-time analytics round out the advertiser side, with a generous first-deposit welcome offer.

Publishers and AI app builders get a third path: a chat SDK that drops the same ad format into an AI chat product with roughly three lines of code, plus revenue analytics and a revenue-share arrangement. Across all three flows Idlen emphasizes privacy, no latency impact, and cancel-anytime terms. A reporting blog, comparison pages, and a calculator that estimates earnings based on daily coding hours are also part of the site.

**Pricing & Plans:** Free for developers (extensions are free and earn a revenue share); advertisers fund campaigns on a paid basis, with a first-deposit bonus offer. Publishers integrate the SDK and share revenue.

- **IDE, browser and Firefox extensions:** Install for VS Code, Cursor, and Windsurf, or add a Chromium and Firefox extension, then keep using your usual AI tools with no workflow changes.
- **Privacy-first local analysis:** Package.json is inspected on your own machine to match relevant ads, and only anonymous keyword tags are sent; source code is never read, stored, or transmitted.
- **Stack-based advertiser targeting:** Campaigns reach audiences defined by technologies in their code, such as React, Python, AWS, or Kubernetes, instead of third-party browsing cookies.
- **Flexible payouts:** Withdraw earnings through Stripe or PayPal, or take API credits with a bonus, with referrals earning a share of what they bring in.
- **Chat monetization SDK:** AI chat products can embed the ad format with about three lines of code, using a sandbox to preview which ad would serve before going live.

**Strengths:** Extension installs in one click and requires no change to existing AI workflows; Local package analysis means source code never leaves the developer's machine; Multiple payout routes including Stripe, PayPal, and bonus-value API credits; Advertisers can target by real technology stack instead of intrusive tracking

**Limitations:** Earnings depend on AI usage volume and ad inventory fill rates, so amounts vary month to month; Coverage is tied to a set of supported editors and browsers rather than every environment; The platform is comparative young, so long-term advertiser demand is still developing
