What is Mindwtr?
Mindwtr is a local-first GTD (Getting Things Done) application for macOS. It implements David Allen's productivity methodology—capture, clarify, organize, reflect, engage—in a clean native interface where all your data stays on your Mac. No cloud accounts, no sync servers, no data leaving your machine. GTD is a productivity system built around one principle: your brain is for having ideas, not holding them. You capture every task, thought, and commitment into a trusted system (the Inbox). You clarify each item (is it actionable? what's the next step?). You organize it (into projects, contexts, or reference). You reflect weekly (the Weekly Review). And you engage—do the work, confident that nothing is slipping through the cracks. Most GTD apps—Todoist, OmniFocus, Things—store your data in the cloud. That's convenient for sync but problematic for privacy. Your task list reveals what you're working on, what's stressing you, and what your priorities are. Mindwtr's local-first approach means this data never leaves your Mac. There's no account creation, no terms of service, no third-party data access. The quick capture feature is the most important workflow element. A global keyboard shortcut opens a capture window from any app—type your thought, hit Enter, and it lands in your Inbox. The friction between 'I just thought of something' and 'it's captured in my system' is under two seconds. This low-friction capture is what makes GTD actually work in practice—if capturing is annoying, you stop capturing, and the system falls apart. Mindwtr includes a guided Weekly Review that walks you through each GTD step: process the Inbox, review active projects, check waiting-for items, update next actions, and clear your head. The review takes 30-60 minutes depending on volume. Most GTD practitioners agree that the Weekly Review is the single most important GTD habit—it's what keeps the system trustworthy. Mindwtr makes it structured enough that you don't skip steps. Context lists (@computer, @phone, @errands, @office, @home) organize your next actions by what tools or location you need. When you sit down at your Mac, filter by @computer and see everything you can do right now. When you're running errands, filter by @errands. Contexts answer 'what should I do next?' based on where you are and what's available.

The case for keeping your task management system off the cloud.
History & Background
David Allen published 'Getting Things Done' in 2001. The methodology predates smartphones and cloud computing. Early GTD implementations used paper (the original medium), then desktop apps like Palm Desktop, then cloud-based tools like Remember the Milk, Todoist, and OmniFocus. The cloud era made sync easy but introduced privacy trade-offs. Your task list—every commitment, worry, and plan—now lived on someone else's server. The local-first movement (inspired by Ink & Switch's 2019 paper on local-first software) argues that personal data should stay personal. Mindwtr applies this principle to GTD.
How It Works
Mindwtr stores all data locally, typically in a structured format (JSON or SQLite) within your user directory. The app reads and writes directly to this local store—no API calls, no authentication, no network requests. This architecture means the app works offline, launches instantly (no sync loading), and can never lose data due to a cloud service outage. The trade-off is that sync between devices requires manual setup (Syncthing, iCloud Drive pointing to the data directory, or git).
Ecosystem & Integrations
Local-first productivity tools are a small but growing category. Obsidian stores notes locally. Standard Notes encrypts and stores locally. Mindwtr stores tasks locally. The philosophy is consistent: your data, your machine, your control. For GTD specifically, the local-first approach means your weekly review data, someday/maybe lists, and project plans never leave your Mac—information that many people consider deeply personal.
Future Development
Local-first apps face a core challenge: how to provide device sync without cloud servers. Emerging technologies like CRDTs (Conflict-free Replicated Data Types) and peer-to-peer sync (used by apps like Muse and some Obsidian plugins) may eventually give Mindwtr cross-device sync without a central server. Until then, the app serves users who prioritize privacy over convenience—a growing segment.
Key Features
GTD Workflow Implementation
Mindwtr implements the five phases of GTD: Capture (get everything into the Inbox), Clarify (process each item—is it actionable?), Organize (assign to projects, contexts, and reference), Reflect (Weekly Review), and Engage (work from context lists). The app's structure maps to the methodology—Inbox, Projects, Next Actions, Waiting For, Someday/Maybe, and Reference. If you've read David Allen's book, Mindwtr's interface will feel immediately familiar.
Quick Capture
A global keyboard shortcut (configurable) opens a capture window from any application. Type your thought, press Enter, and it's in your Inbox. The window disappears and you're back to what you were doing. Capture supports text, URLs (paste from clipboard), and multi-line notes. The speed of capture is critical—GTD only works if you actually capture everything, and that requires near-zero friction.
Context Lists
Organize next actions by context: @computer, @phone, @errands, @office, @home, @calls, or any custom context you create. When you process an Inbox item and determine the next action, assign a context based on where/how you'll do it. Later, when you're ready to work, filter by your current context to see only relevant actions. This prevents the paralysis of seeing your entire task list—you only see what's doable right now.
Guided Weekly Review
A structured walkthrough of the GTD Weekly Review process. Mindwtr presents each step in sequence: empty the Inbox, review active projects (are they still relevant? what's the next action?), check Waiting For items (follow up needed?), review Someday/Maybe (promote or remove?), and do a brain dump (capture anything new). The guided review takes 30-60 minutes and ensures you don't skip steps—the most common failure mode for GTD practitioners.
Local-First Storage
All data is stored locally on your Mac in a portable format (typically JSON or SQLite in your home directory). No cloud sync, no account required, no internet connection needed. You own your data completely—back it up with Time Machine, version control it with git, or copy the directory to another Mac. The trade-off: no automatic sync between devices. The benefit: complete privacy and data sovereignty.
Project Management
GTD defines a 'project' as any outcome requiring more than one action step. Mindwtr's project view lists all active projects with their next actions, completion status, and deadlines (optional). Each project can have notes, reference materials, and a list of supporting actions. The project view answers 'what am I committed to?' at a glance—a question that's hard to answer when tasks are scattered across apps and notebooks.
Who Should Use Mindwtr?
1GTD Practitioner Leaving Todoist
A seasoned GTD user has been on Todoist for three years but is uncomfortable with their entire task history on Todoist's servers. They export from Todoist, import into Mindwtr, and rebuild their GTD system locally. The workflow is familiar (Inbox, projects, contexts, weekly review) but the data stays on their Mac. They back up the Mindwtr data directory with git for version history.
2Privacy-Conscious Developer
A developer avoids cloud services for personal data. They keep notes in local Markdown files, use Signal for messaging, and run a local email server. Mindwtr fits this philosophy—their task list, project plans, and someday/maybe ideas never touch a server. The global capture shortcut integrates with their terminal-heavy workflow.
3Freelancer Managing Client Projects
A freelance consultant manages 5 active client projects simultaneously. Each project has a next action, waiting-for items (client responses), and reference notes. Mindwtr's project view gives a dashboard of all commitments. The Weekly Review ensures nothing falls through cracks between client calls. Context lists separate @computer work from @calls and @meetings.
How to Install Mindwtr on Mac
Mindwtr is available through Homebrew as a macOS cask.
Install via Homebrew
Run `brew install --cask mindwtr`. The app installs to your Applications folder.
Set Up Quick Capture Shortcut
Open Mindwtr Preferences and configure the global capture shortcut. Choose a key combination you don't use in other apps (e.g., Ctrl+Space, Hyper+C). This is the most important configuration step.
Create Your Context Lists
Set up contexts that match your real-world environments: @computer, @phone, @office, @home, @errands, @calls. Custom contexts are fine—create whatever matches how you work.
Do a Full Brain Dump
Spend 30-60 minutes capturing everything on your mind into the Inbox. Every task, idea, concern, project, and someday-maybe. Then process each item through GTD's clarify and organize steps.
Pro Tips
- • Don't skip the initial brain dump. GTD only works when everything is captured—if half your tasks are in your head and half are in Mindwtr, you won't trust either system.
- • Schedule your first Weekly Review for the end of your first week. This is where GTD clicks—reviewing everything and knowing nothing is forgotten.
- • Back up the data directory regularly. Since there's no cloud backup, a Time Machine backup or git version control protects against data loss.
Configuration Tips
Set the Capture Shortcut First
The global capture shortcut is the most important feature to configure. Without it, you'll forget to capture things because opening the app takes too long. Set it to something accessible from any application—Ctrl+Space, Cmd+Shift+I, or a Hyper key combination if you use a keyboard remapper.
Start with 5-7 Contexts
Don't create too many contexts initially. Start with @computer, @phone, @errands, @home, @office, and @calls. Add more only when you find yourself needing a distinction that existing contexts don't cover. Too many contexts make the system harder to maintain.
Alternatives to Mindwtr
GTD-style task managers range from simple to full-featured, local to cloud-based.
OmniFocus
OmniFocus ($49.99 one-time or $9.99/month subscription) is the gold standard for GTD on Apple platforms. It supports projects, contexts (now called tags), perspectives (custom filtered views), forecast view, and cross-device sync via OmniSync Server. OmniFocus is more powerful than Mindwtr in every feature dimension but costs money and syncs to a cloud server. If you want the most capable GTD tool and don't mind paying, OmniFocus is the choice.
Things 3
Things 3 ($49.99 Mac, $9.99 iPhone) is a beautifully designed task manager that supports GTD-style workflows. It uses iCloud for sync, has a polished native UI, and handles projects, areas, and tags. Things is less strict about GTD methodology than Mindwtr (no guided Weekly Review, no formal clarify step) but more polished and feature-rich.
Todoist
Todoist (free tier, $5/month for Pro) is the most popular cloud-based task manager. It supports projects, labels (similar to contexts), filters, and collaboration. Todoist works everywhere (Mac, iOS, Android, web, browser extensions). The trade-off: your data lives on Todoist's servers. If cross-platform sync matters more than privacy, Todoist is the pragmatic choice.
Pricing
Mindwtr is free and open-source. No subscription, no premium tier, no account required, no feature limits. The source code is available on GitHub.
