## 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

## PromptLocker

PromptLocker targets a problem that regulated practices already have: staff quietly pasting client files, tax records or patient information into consumer AI tools. Instead of trying to ban those tools, PromptLocker provides a sanctioned alternative. The governance layer is deployed inside the firm's existing cloud account, so prompts, documents and model responses are processed within the firm's own environment and under its own access controls rather than on a shared multi-tenant backend.

On top of that runtime, PromptLocker adds an append-only audit log. Every query, model call, document access and returned response is timestamped, attributed to a user and linked to a matter, which makes it possible to pull a compliance report for any date range without reconstructing history by hand. A leader portal gives owners and managing partners a firm-wide view of AI activity, and the audit trail stays in the customer's account rather than with the vendor.

The compliance side is deliberately vertical-specific: onboarding is designed to produce the documentation a given practice actually needs, such as WISP addenda, business associate agreements, ABA Opinion 512 summaries or Reg S-P governance policies. The platform is positioned as an early-access offering for regulated professional firms rather than a general-purpose developer framework, and it does not publish list pricing — access is arranged through a direct conversation about the firm's AI exposure.

**Pricing & Plans:** PromptLocker does not publish list pricing. The site describes an early-access program in which interested firms request access and have a direct conversation about their current AI exposure and the governance work required. Treat any pricing as custom and confirmed during that conversation.

- **Runs inside your own cloud account:** The governance layer deploys in the firm's existing cloud account, so client files, patient records and financial data are processed within the firm's own environment and access controls.
- **Append-only audit log:** Every query, model call, document access and response is timestamped, user-attributed and matter-linked, making firm-wide AI activity reconstructable and reportable.
- **Compliance documentation at onboarding:** Onboarding is built to deliver the artefacts a specific regulated vertical needs, such as WISP addenda, BAAs, ABA Opinion 512 summaries and Reg S-P governance policies.
- **Leader portal:** Owners and managing partners get a web dashboard showing every AI interaction across the firm, with full session logs exportable for any date range.
- **Sanctioned alternative to shadow AI:** Rather than banning consumer AI tools, PromptLocker gives staff a governed tool that works with the right documents already in place.

**Strengths:** Deploys in the customer's own cloud account, so client data does not leave the firm's network; Purpose-built for regulated verticals rather than a generic LLM tool; Immutable, matter-linked audit log supports compliance reporting on demand; Onboarding oriented around concrete compliance artefacts instead of roadmap promises

**Limitations:** No published pricing; you must request access and negotiate; Early-access stage, so features and terms may still change; Focused on regulated professional services, which makes it a poor fit for casual or hobbyist users
