What is Sea Notes?

Sea is a local-first, Markdown-based note-taking app designed to give you a calm place to think, write, and organize your ideas.

Instead of trying to turn note-taking into a complicated productivity system, Sea focuses on a simpler idea: your notes should stay easy to write, easy to find, and easy to keep.

A calm space for writing

Sea is built around a distraction-free editor that lets you focus on your words.

You can write naturally using Markdown without constantly switching between an editor and a preview. Sea keeps the document readable while still giving you access to the underlying Markdown whenever you need it.

Your notes remain portable and are not tied to a proprietary writing format.

Local-first by default

Sea is designed to work primarily with data stored on your own device.

You can create, edit, search, and organize your notes without needing a constant internet connection.

This also means Sea does not require your writing to live on a remote server just for the app to work.

Some optional features may use an internet connection, such as checking for updates or future synchronization features, but the core writing experience is designed to remain local.

Organize without folders

Sea does not require you to build and maintain a complicated folder hierarchy.

Instead, you can organize information using:

• Tags and nested tags

• Search

• Wikilinks

• Backlinks

• Note relationships

This makes it easier for a note to belong to more than one context without having to decide on a single folder where it must live.

For example, a note could relate to both #university and #projects/sea while also linking directly to other relevant notes.

Markdown-native

Markdown is at the core of how Sea represents your writing.

You can use familiar syntax for headings, lists, links, code blocks, quotes, task lists, and other formatting.

Sea presents that Markdown in a more comfortable writing interface while keeping the underlying structure predictable and portable.

This makes it easier to move your writing between tools and reduces dependency on Sea itself.

Notes can be connected

Sea supports links between notes using wikilinks.

For example:

[[Project Ideas]]

A note can also show which other notes link back to it through backlinks.

Over time, this lets your notes form useful connections naturally, instead of requiring you to manually organize everything upfront.

Intelligent features stay out of your way

Sea may provide optional features that help you understand and organize your notes, such as discovering related notes or suggesting useful organization.

These features are designed to assist your existing workflow rather than take control of it.

You remain in control of how your notes are organized and what features you choose to enable.

Who is Sea for?

Sea may be a good fit if you:

• Prefer writing in Markdown

• Want your notes available offline

• Care about keeping your data portable

• Do not enjoy maintaining complicated folder structures

• Like connecting ideas through links and tags

• Want a minimal writing environment without giving up powerful organization tools

Sea is intended for anything from quick notes and personal writing to study notes, technical documentation, project ideas, and long-term knowledge.

The idea behind Sea

Sea is built around a simple principle:

Your note-taking app should help you think, not give you another system to maintain.

Write first. Organize naturally. Keep your notes yours.
