Write.md

What it does

Write.md is a Markdown editor for macOS that stores documents as local files. It provides optional Vim key bindings and a customization system called "appearance profiles" that lets users adjust typography, colors, backgrounds, window opacity, and layout. The editor includes basic spell-checking and grammar suggestions that run locally without connecting to external services.

Who it is for

The tool targets writers and developers who want a distraction-free writing environment and prefer to own their files outright. It appeals to users comfortable with Markdown who value privacy and control over their appearance settings. The emphasis on customizable "rooms for writing" suggests it may suit people who switch between different writing contexts or moods throughout the day.

Pricing

Free. The application is free to download and use with no paid tier or premium features mentioned.

How it stands out

Write.md positions itself as privacy-first: no accounts, no telemetry, no analytics, and documents stored as plain files rather than in a vendor database. The appearance profile system goes deeper than typical light/dark mode toggles, letting users save combinations of font, size, line height, page width, colors, opacity, glass effects, borders, and backgrounds as reusable configurations. It ships with no bundled theme catalog, pushing users to build profiles manually within the editor. The optional Vim mode can be toggled without affecting the rest of the interface. The application is open source under the Apache 2.0 license, making the source code available on GitHub. Currently it runs only on Apple silicon Macs.

What a founder should check

A competitor should understand whether the local-only correction system (US English only by default) creates meaningful friction compared to cloud-based alternatives like iCloud-synced Notes or web editors with more sophisticated language tools. Second, verify the actual audience size for appearance customization as a primary selling point—whether users see profile switching as valuable or as unnecessary configuration overhead. Third, examine whether the privacy-first positioning and open-source nature translate into user retention or word-of-mouth growth in practice, or whether most Markdown editor users remain indifferent to telemetry and accounts as long as the core writing experience is solid.
