A free Markdown knowledge base in your browser

Slate is a place to collect what you learn and connect it. You write notes in Markdown, link one note to another with [[double brackets]], and Slate keeps track of which notes point where. Open any note and you see both the notes it links to and the notes that mention it, so a fact you wrote down months ago turns up again when it is relevant.

It suits students building course notes, developers keeping a personal wiki of commands and fixes, writers tracking characters and places, and anyone who has outgrown a flat list of notes. Tags and folders give you two more ways to group things, and the graph view draws your whole vault as a network, which shows clusters and loose ends at a glance.

Your vault lives in your free TechTools account, so it is the same on every computer and phone you sign in from. There is nothing to install and no sync to configure: changes save automatically a moment after you stop typing.

Features

  • Markdown editor. Edit, Split and Preview modes, GitHub-flavoured Markdown with tables, checklists and code blocks, and Tab for indenting.
  • Wiki-links with autocomplete. Typing [[ suggests notes by title; [[Title|text]] sets your own link text; a link to a missing note creates it on click.
  • Backlinks. The Connections panel shows Links from this note and Linked mentions, each with a count.
  • Tags. Every #tag is collected into the sidebar tag cloud and the note's tag list, and a click on a tag filters the vault.
  • Folders and pins. Notes group by folder in the sidebar, folders collapse, and pinned notes stay on top.
  • Knowledge graph. A force-directed map of all notes and links: drag, pan, zoom, hover to highlight neighbours, click to open.
  • Search. Filter the vault by words in note titles and text as you type.
  • Autosave and sync. Edits are saved to your account automatically and appear on any device you sign in from.
  • Example notes. An empty vault offers a small linked set of guide notes to try everything out.

How to build a linked Markdown knowledge base in Slate

  1. Create your vault

    Press Create my vault for a one-click account, or log in or register with your TechTools account. Save the generated username and password when they appear.

  2. Write a note in Markdown

    Press New, give the note a title and write Markdown. Switch between Edit, Split and Preview; every change saves itself.

  3. Link notes with double brackets

    Type [[ and pick a note from the suggestions, or type a new title. A dimmed link points to a note that does not exist yet; click it to create that note.

  4. Add tags and folders

    Write #tags anywhere in the text and put the note in a folder. The sidebar groups notes by folder and lists every tag; click a tag to filter.

  5. Explore the graph

    Press Graph to see every note as a node and every wiki-link as an edge. Drag nodes, zoom, hover to highlight neighbours and click a node to open its note.

Tips for a knowledge base that stays useful

  • Keep one idea per note and give it a clear title. Titles are what links point to, so short and specific works best.
  • Link freely, even to notes you have not written yet. The dimmed links become a to-do list of topics to fill in.
  • Create a few hub notes, such as a project or a course, that link to everything related. They become the large nodes in the graph.
  • Use tags for status or type (#todo, #idea, #reference) and folders for broad areas, so the two never compete.

Frequently asked questions

Is Slate free?

Yes. Slate and the TechTools account that stores your vault cost nothing.

Where are my notes stored?

On the TechTools server, in your account. Slate loads only the notes of the signed-in account, so nobody else can open your vault, but notes are not end-to-end encrypted: keep passwords and other secrets elsewhere.

Which Markdown does Slate support?

GitHub-flavoured Markdown: headings, bold, italic, strikethrough, lists, checklists, tables, quotes, links and fenced code blocks. A single line break is kept as a line break. On top of that come [[wiki-links]] and #tags.

How do wiki-links and backlinks work?

[[Note title]] links to the note with that title, and [[Note title|text]] shows your own link text. The Connections panel lists the links from the open note and, under Linked mentions, every note that links to it.

What happens to links when I rename a note?

Links use the note title, and renaming does not rewrite them. Links that used the old title show as missing until you change them to the new title.

Does Slate work on a phone?

Yes. On narrow screens the vault and the Connections panel open as drawers from the navbar buttons, and the editor switches between Edit and Preview. Split view needs a screen at least 1024 pixels wide. The graph works with touch.

How long can a note be?

A title can have up to 255 characters and the text up to 200,000 characters, which is far more than a typical note.

Can I export my notes?

My data in the account menu downloads the data your TechTools account keeps in every tool, Slate notes included, as one file. A note larger than 100 KB appears there only as its size, and there is no export to separate Markdown files yet.

Is Slate like Obsidian?

It borrows the same ideas: Markdown notes, [[wiki-links]], backlinks, tags and a graph. The difference is where notes live: Slate keeps them in your TechTools account and runs in the browser, so there are no local files, no plugins and nothing to install.
