A Second Brain For Creators

One place for all of your ideas, notes, highlights, and writing. It's free for personal use.

"Kortex is like if Google docs, Notion, and Obsidian had a baby. All of my ideas, highlights, and past writing are finally in one place."

Get Started

For Minimalist Writers, Creators, & Note-Takers

Most apps add so many features that make it difficult to just write. We don't alienate those who want a simple workflow. Kortex is built around one simple workflow, capture and create.

Step 1

Capture Ideas Fast

Stop texting yourself ideas and reminders you forget about. Capture any idea, organize it quickly with tags, connect it to a document, and have it ready when it's time to write.

Kortex is built by creators who were fed up with tools that are decent for organization, but suck for writing. Stop putting your ideas in one app, your notes in another, and your writing in another. This ruins the creative process without you realizing it (and you're probably annoyed with all the tabs you have open).

You don't need an English degree to write in a way that helps you stand out. You need the right ideas, in the right place, at the right time. You can't write fast because you stare at a blank screen and expect ideas to come to you. Kortex feeds you your best ideas when you need them.

One Workflow
Fast Writing
Your Digital Garden

How many bookmarks, notes, captures, documents, and highlights are collecting dust in a corner of your workspace? They should grow in value as you add more. Kortex helps you exchange your digital swamp for a digital garden.

For Those Who Want A Bit More Power!

Transfer your workflow to a less overwhelming environment (without sacrificing your favorite features). Kortex has everything you need to do it all: Build a second brain, write a best-selling book, create a batch of engaging social posts, or write a viral video script.

Eliminate Writer's Block

Build templates, outlines, and guide your writing with Kortex Elements. What looks like a simple feature has become an instant "must have" for note-takers and writers.

Never Lose An Idea Again

Most search features are useless.Kortex allows you to search by tags, related words, document contents, captures, elements, and highlights so you can find those long-lost ideas without having to know exactly what to search for.

Own Your Knowledge

Never feel locked into Kortex. Export your files or workspace as markdown at any time.

Share Your Notes & Writing

Share individual documents and templates with friends, students, and teams, or create a new workspace for collaboration. Easily duplicate documents across workspaces.

All Highlights In One Place

Your highlights don’t belong in random documents that are messy and difficult to navigate. Save highlights from your favorite PDFs, books, tweets, articles, and more in a simple and searchable library view. Readwise integration available. Native Kindle highlights, web clipper, and audio highlighter coming soon.

Close All Of Your Tabs

Discover new ideas you won’t find with one-dimensional note-taking and writing apps.Connect your documents, captures, elements, and highlights and have them all open in one clean interface.

"Been writing and dumping ideas into the app all week. Before I was putting ideas in random different place like Notion, Google Drive, etc. This app is giving me the opportunity to collect, compile, and organize. Freaking awesome."

"I was an early adopter of using a second brain for writing. For years I used Roam Research. Kortex is a huge improvement. Without tools like Kortex, my career wouldn't be the same."

"Obsidian was my favorite note-taking app, and I can confidently say WAS. Good work ya'll."

"I've been writing letters for a year or so now, and they've always been pretty good… but DUDE. The ease of merging ideas in Kortex?! It's like a dream come true!"
