    Callum Alpass

    Callum Alpass is an individual/solo developer and open-source creator, not a separately identified company. He builds TaskNotes, a file-first task-management system that keeps structured task records in portable Markdown and makes them usable in Obsidian, the web, Android, and iOS; the official site describes the shared model as status, priority, dates, projects, contexts, recurrence, reminders, relationships, and custom fields.

    TaskNotes for Obsidian
    Active through September 2026; stable version 4.13.1

    Open-source Obsidian task-management plugin in which every task is a separate Markdown note and views are powered by Obsidian Bases.

    TaskNotes v5 / TaskNotes app
    2026 beta

    Web-first client packaged for Android and iOS, compatible with TaskNotes v5 collections using the mdbase 0.3.0 specification; supports hosted or encrypted-relay Markdown collections.

    TaskNotes Workflows
    2026-06 initial development; 0.1.4 released 2026-08-09

    Optional Obsidian companion plugin for Markdown-defined automation, including task events, schedules, manual commands, typed actions, and editable workflow notes.

    TaskNotes CLI
    Public repository; date not stated on the fetched source

    Command-line companion exposing task creation and operations, search, JSON output, and calendar commands for Google, Microsoft, and subscriptions.

    Market Position

    TaskNotes differentiates from conventional database-backed task managers by treating each task as a portable Markdown note and using Obsidian Bases files as inspectable views. It is positioned alongside other Obsidian task tools such as the Tasks plugin, but emphasizes one-note-per-task structure, richer metadata, calendar/time tracking, APIs, and a shared v5/mdbase model spanning Obsidian and standalone clients.

    Leadership

    Founders

    CA

    Callum Alpass

    Independent software developer and maintainer of the callumalpass GitHub projects. GitHub identifies him as the author of TaskNotes, and the repository manifest names him as author; the Obsidian Hub lists him as author of the BibLib plugin as well.

    Executive Team

    CA

    Callum Alpass

    Creator and maintainer

    GitHub repository owner and named author of TaskNotes; also associated with the BibLib Obsidian plugin and related mdbase/TaskNotes companion projects.

    Founding Story

    TaskNotes began from a file-first, portable-data vision: each task is its own Markdown note with YAML frontmatter rather than a plugin-specific database. The project uses Obsidian Bases for views so users can read, edit, transform, and migrate their task data with ordinary tools. The later v5/app direction extends the same portable model to shared mdbase collections across Obsidian and standalone clients.

    Business Model

    Revenue Model

    The core TaskNotes Obsidian plugin is open source under the MIT License. The standalone web/Android/iOS TaskNotes app is in beta; the fetched official pages describe hosted mdbase and encrypted-relay connectivity but do not state a paid pricing model.
