today vs Obsidian: two tools for different parts of your knowledge work practice

today
Calm daily planner
Time blocks, focus, commitments, reflection

Obsidian
a markdown-based personal knowledge management tool with a local-first approach and extensive plugin ecosystem

Obsidian and today: solving fundamentally different problems

Obsidian is a personal knowledge management (PKM) tool — it organizes notes, links concepts together in a knowledge graph, and manages long-term thinking through markdown files stored locally. Its daily notes feature enables a journaling and task-capture workflow. Today is a daily execution planner: time blocks, focus sessions, commitment tracking, energy check-ins, reflection. The overlap is in the 'daily notes' territory — both can serve as an end-of-day reflection tool. Outside that narrow overlap, they serve completely different purposes and complement each other without competition.

When Obsidian users add today to their workflow

Many Obsidian power users already use daily notes for journaling and task capture. They add today when they find their Obsidian daily notes aren't giving them the execution tracking they want: session logging isn't built into daily notes, energy check-ins require custom templates, calendar sync is plugin-dependent and fragile, and the friction log and outcome model require significant custom implementation. Today provides these out of the box, making it a natural complement for Obsidian users who want stronger daily execution infrastructure without building it themselves in markdown and plugins.

What Obsidian does that today doesn't attempt

Obsidian's knowledge graph — the network of linked notes that represents your personal knowledge base — is something today doesn't attempt at all. Meeting notes, project documentation, literature notes from books and papers, connected concept maps: all of these belong in Obsidian, not in today. Today is a narrow daily execution tool; Obsidian is a lifetime knowledge accumulation system. They operate at different time scales (today's data is meaningful over weeks; Obsidian's knowledge compounds over years) and different purposes.

The local-first vs. cloud tradeoff

Obsidian is local-first: all your notes are markdown files on your device, synced optionally via Obsidian Sync ($10/month), iCloud, or GitHub. Today stores your planning data in the cloud via Supabase. For users with privacy concerns about cloud storage of personal data, Obsidian's local-first approach is preferable. For users who need seamless access across multiple devices without sync configuration, today's cloud-first approach is more convenient. Both approaches have legitimate tradeoffs — the right choice depends on your device ecosystem and privacy priorities.
