Syncist (Todoist Sync) - Obsidian Plugin

Code 100% written by AI; plug-in 100% validated and tested by human.

Summary

With this plugin it is possible to create Todoist tasks from Obsidian and keep them in sync bidirectionally. Its usage is very simple after the plugin has been connected to your Todoist account. When you add the #todoist tag to a task (or checkbox item) it will automatically be created on Todoist and from that moment onward, the Todoist and Obsidian task will be synced.

Features

• Bidirectional Sync: Changes in Obsidian or Todoist are synced both ways
• Subtasks: Indented tasks beneath a #todoist parent are synced as subtasks automatically — no tag needed on each child
• Import from Todoist: Search and import any Todoist task (with its subtasks) into your note via a fuzzy-search modal
• Projects & Labels: Per-task project assignment with 📁 ProjectName metadata, bidirectional label sync via #hashtags
• Query Blocks: Embed live Todoist task lists in your notes using syncist code blocks (e.g., filter: today)
• Tasks Plugin Compatible: Works with the popular Obsidian Tasks plugin emojis (📅, ⏫, 🔼, 🔽)
• Configurable: Customize sync tag, default project, sync interval, and conflict resolution
• Commands: Quick commands to create tasks, import tasks, and trigger sync
• Conflict Resolution: Choose how to handle conflicts (Obsidian wins, Todoist wins, or ask)
• Zero Dependencies: Direct Todoist API v1 integration via Obsidian's built-in requestUrl — no external SDKs
• AI-Crafted: Code 100% written by AI; plug-in 100% validated and tested by human

Usage

Creating Tasks

Add the #todoist tag to any task:

- [ ] Buy groceries #todoist
- [ ] Meeting with team #todoist 📅 2026-01-28 ⏫

After sync, the task will have a Todoist ID:

- [ ] Buy groceries #todoist <!-- todoist-id:8765432109 -->

Subtasks

Indent tasks beneath a #todoist-tagged parent. Subtasks inherit the sync tag automatically — you do not need to add #todoist to each one:

- [ ] Buy groceries #todoist <!-- todoist-id:111 -->
  - [ ] Milk <!-- todoist-id:222 -->
  - [ ] Bread <!-- todoist-id:333 -->
  - [ ] Eggs

• Subtasks are synced as Todoist subtasks (using parentId)
• New indented tasks without a Todoist ID are created as subtasks on the next sync
• Subtask hierarchy is preserved in both directions

Importing Tasks from Todoist

Use the command "Import task from Todoist" to search for any open Todoist task and insert it at your cursor:

1. Open the command palette (Ctrl/Cmd + P)
2. Run "Syncist: Import task from Todoist"
3. Search by task content, project, label, or due date
4. Select a task — it and its subtasks are inserted as synced markdown

Projects and Labels

Assign a project to a task using the 📁 emoji:

- [ ] Design review #todoist #design #urgent 📁 WorkProject 📅 2026-03-05 <!-- todoist-id:123 -->

• 📁 ProjectName sets the Todoist project for the task (overrides the default project)
• #hashtags (other than the sync tag) are synced as Todoist labels, bidirectionally
• Project names are resolved from the Todoist project list and cached

Query Blocks (Show Today's Tasks)

Embed a live, interactive task list in any note using a syncist code block:

```syncist
filter: today
```

The block renders as a styled task list with checkboxes, priorities, projects, and due dates. You can complete or reopen tasks directly from the rendered block.

Supported filters (uses Todoist filter syntax):

Filter	Description
filter: today	Tasks due today
filter: overdue	Overdue tasks
filter: today | overdue	Combined filters
filter: #ProjectName	Tasks in a project
filter: @label	Tasks with a label
filter: p1	High priority tasks

Each query block includes a refresh button and shows when it was last updated.

Commands

• Create Todoist task from current line: Convert current line to a synced task
• Import task from Todoist: Search and import a Todoist task at cursor
• Sync with Todoist now: Manually trigger sync
• Open Todoist Sync settings: Quick access to settings

Supported Task Formats

Emoji	Meaning	Todoist Mapping
📅	Due date	Task due date
⏫	High priority	Priority 4
🔼	Medium priority	Priority 3
🔽	Low priority	Priority 2
📁	Project	Task project

Network Usage

This plugin connects directly to the Todoist API v1 (via Obsidian's built-in requestUrl) to sync tasks. There are no external SDK dependencies. Your Todoist API token is stored locally in Obsidian's plugin data and is only used to communicate with Todoist's servers (api.todoist.com).

Development

To build the plugin from source:

npm install
npm run build

To lint:

npm run lint
