Standard Notes

Standard Notes is a privacy-first note-taking app that encrypts every note and file with audited, industry-standard end-to-end encryption before it ever leaves the device. Only the account holder holds the keys needed to decrypt their data, and the company positions itself directly against services like Evernote, Google Keep, and Notion on the grounds that those services cannot fully protect user data from employer or government access. The app syncs notes and files across unlimited devices on Windows, Mac, Linux, iOS, Android, and the web, and it keeps an offline copy of everything so notes remain accessible without an internet connection. Beyond plain notes, it supports markdown, rich text, task lists, code snippets, and spreadsheets through an extensible editor system, and its source code is open and independently security-audited. The company states it takes no venture capital and earns 100 percent of its revenue from paying subscribers.

Notability

Notability is a digital note-taking app that combines handwriting, typed text, live audio recording and transcription, and AI-powered study tools like flashcard and quiz generation. Notes can import PDFs and documents, be searched by handwriting, and be summarized or queried through a chat-with-your-notes feature. Originally an Apple-only app, Notability has expanded beyond iOS, iPadOS, and Mac to Android and the web, with notes syncing across devices. It uses a freemium model with a free Starter tier, several paid subscription tiers, and a one-time-purchase Classic option available to users grandfathered from before the subscription switch.

Simplenote

Simplenote is a minimalist note-taking app, made by Automattic, focused on simplicity and speed over complex features. Notes sync automatically and in real time across iOS, Android, Mac, Windows, Linux, and the web with no manual sync step required.
