Last Updated: October 21, 2025
Some note takers prefer keeping their data stored locally rather than relying entirely on the cloud. Local-First Note Apps store your notes directly on your device, syncing when needed while keeping you in control of your own data.
These tools appeal to privacy conscious users, developers, and offline workers who want reliability and control over where their notes actually live. Local storage also means your notes remain accessible even without an internet connection.

Obsidian is a note-taking app that works with plain text files stored directly on your device. You can write notes, link them together, and see how your ideas connect through a visual graph. Unlike cloud-based tools, everything stays private on your computer.
The app uses simple text files with basic formatting, which means your notes remain readable even without Obsidian. You can link any note to another, creating connections that help you discover patterns in your thinking. This makes it great for building knowledge over time.
There is a free version with all core features and optional paid services for cloud syncing and web publishing. The app works on computers, phones, and tablets.
Logseq is an open-source note-taking tool that helps you capture and connect your thoughts. Everything you write is stored as plain text files on your device, giving you complete control over your data. You never have to worry about a company shutting down or changing their prices because your files belong to you.
The app works with a daily journal where you can write notes, create tasks, and link ideas together. When you link notes, Logseq shows you all the connections, helping you see relationships between different topics. This creates a graph of your knowledge that grows over time.
You can use it on Windows, Mac, Linux, iPhone, and Android. The basic app is free forever, with optional paid sync to keep your notes updated across devices.
AFFiNE is a workspace application that brings together three main tools in one place: documents for writing and note-taking, whiteboards for visual thinking and drawing, and databases for organizing information. Unlike cloud-first tools, AFFiNE takes a local-first approach, which means your data lives on your computer first and only syncs to the cloud if you choose.
You can switch between document mode and whiteboard mode easily, turning any page into a drawing canvas and back again. This flexibility helps you work the way your mind works, not the way the software forces you to work. AFFiNE is completely open-source, meaning the code is public and can be customized. It works on Windows, Mac, Linux, and has mobile apps too.
Anytype is a tool for organizing your notes, tasks, files, and projects while keeping everything private on your device. You create content using objects, which are like structured notes with properties you can customize. For example, a book object can have an author, rating, and notes all connected together.
The app works offline and stores data locally with encryption, meaning your information stays on your device unless you choose to sync it. When you do sync, it uses secure connections between your devices. You can create databases, link related information, and build visual connections between different pieces of content.
There is a free plan with limited cloud storage, plus paid plans for those who need more backup space and advanced features like shorter custom names.
SiYuan is a personal knowledge management system that treats every piece of content as a block. These blocks can be linked, referenced, and organized in multiple ways. Unlike traditional note-taking apps, SiYuan gives you complete control by storing everything locally on your device.
The tool uses a block-based approach where even whole documents are treated as blocks. This makes it easy to split, move, and connect information without breaking existing links. You can create bidirectional links between ideas, use outlines to organize thoughts, and view your knowledge as a graph.
It includes features like mathematical formulas, charts, flashcards for learning, and database views. The app is self-hosted, meaning you own your data completely.
Trilium Notes is a note-taking application that lets you organize information in a tree structure. Each note can contain text, images, code, diagrams, or other content types. Unlike basic note apps, Trilium allows one note to appear in multiple places in your tree without copying it, which is called cloning.
The app stores everything in a local database, making it fast even with thousands of notes. You can use a rich text editor for regular writing or a code editor for programming. It also includes features like note linking, full-text search, note encryption for privacy, and web clipping to save websites directly into your notes.
You can use Trilium offline on your computer or set up a sync server to access your notes from multiple devices and through a web browser.
