Citrine

An ADHD-friendly desktop and mobile app for notes, planning, and task management—designed to help you capture thoughts, organize without friction, and move forward calmly.

Why Citrine?

Most productivity tools either demand rigid structure up front or overwhelm you with endless configuration, notifications, and streak pressure. Citrine is built to be broadly useful while treating executive-function barriers as first-class design concerns.

You get a guided, approachable starting workflow for daily planning, notes, and tasks— backed by examples and sensible defaults—while staying free to adapt, replace, or ignore any part of it as your system evolves.

Core Goals

  • A Calm, Usable Personal System: Capture notes, ideas, and commitments without demanding perfect structure, and recover calmly when plans change or tasks are missed.
  • ADHD-Friendly Support for Everyone: Reduce blank-page and choice overload by making memory, time, priorities, and next actions visible and manageable.
  • Guided Start, Not Forced Methodology: Start with a coherent workflow out of the box, then customize views, templates, and plugins whenever your needs change.
  • Local-First Data Ownership: Authoritative user data lives in understandable files on your own devices. Core use works offline with no required account; optional sync uses end-to-end encryption.
  • Durable User Control: Portable formats and reversible workflows mean you are never locked into one provider or method.

Guiding Principles

Capture now, organize later

Never force categories, projects, or perfect wording while trying to capture a thought.

One item, many useful views

A note or task can appear in a daily plan, project, or review without duplicate copies.

Make the next step visible

Prefer concrete next actions and start cues over abstract goals and overwhelming backlogs.

Forgiving over punitive

Missed tasks and changed plans lead to calm recovery—never shame, broken streaks, or artificial urgency.
