What is Synap?

Your knowledge deserves a home

Right now, your professional knowledge is probably scattered across a dozen different tools. Notes in one app, tasks in another, content drafts in a third, reference documents in a fourth. You spend more time switching between tools than actually doing your work.

Synap brings everything together in one place. It's a desktop application where you can organize your knowledge, plan your content, manage your tasks, and work with AI — all without leaving a single window.

Built for professionals, not developers

You don't need any technical skills to use Synap. If you can organize files on your computer, you can use Synap. There's nothing to configure, no accounts to create, and no learning curve that requires a manual.

Synap is designed for marketers, consultants, project managers, content creators, founders, and anyone else who needs to stay on top of their knowledge and work. It's the tool that finally makes AI useful for everyday professionals — because when your knowledge is organized, AI can actually help you with it.

Free, offline, and private

Synap is completely free to download and use. It works offline — no internet connection required. And everything you create stays on your computer, not on someone else's server. Your knowledge is yours.

There are no accounts to sign up for, no subscriptions to manage, and no data leaving your machine unless you choose to share it.

Three ways to use Synap

Desktop app is the main experience. It's where you'll do most of your work. Free, full-featured, and available for both macOS and Windows.

Web version is for teams that want to collaborate on shared knowledge. This is a paid service for organizations that need to share and access knowledge together.

Mobile app is coming soon, so you'll be able to access your knowledge on the go.

AI that works with your knowledge

Synap has AI built right in through a feature called Cortex. It's a sidebar where you can ask questions about your own notes, get help drafting content, brainstorm ideas, or work through decisions — all grounded in the knowledge you've already organized.

This isn't a generic chatbot. Because Synap understands how your knowledge is structured, the AI can give you answers that are actually relevant to your work. No technical setup required — it just works.

Getting started is easy

Installing Synap takes less than a minute, and you'll have a workspace ready to explore the moment you open it. In the next section, we'll walk you through the simple installation process.
