About

Decision Log

Read full description

Decision Log is a tool for documenting important decisions, personal and professional. You record not just the decision itself, but why it was made, what the options were, and what comes out of it. So you can revisit your choices, learn from them, and spot patterns. Decide with clarity. Learn from experience. Every day you make decisions, at work, in life, in small habits. Unrecorded, they slip away quickly: why you're doing something, what the context was, what you're thinking. Decision Log helps you capture them, so you can see what really works and how things change over time. Not a journal. Not a habit tracker. Something that was missing in between. In a journal, important decisions drown between daily entries. In a habit tracker, you tick off days, but you never write down why you started, or why you stopped. Decision Log captures what gets lost in both: context, motivation, and the history of changes behind every decision. A habit, an experiment, a tool switch, a resolution โ€” all in one place, with an awareness that grows over time. A decision without context is just a faded memory. You change your diet, buy a flat, leave a project. A few months later, you remember what happened, but not why. And without the "why," you don't know if the decision worked or what the experience taught you. WHAT YOU GET FOR FREE - Track progress โ€” milestones, statuses, outcomes - Overwrite past decisions โ€” replacement chains keep the history visible - Collections, filters and search - Simple ready-to-use or customisable statuses and sections - Built-in templates or your own - Clean Markdown editor - Full history of changes - Import / Export (.md, .txt, ADR) WHEN DECISIONS PILE UP โ€” PRO - Focus mode with Workbench - Stats dashboard โ€” pace, patterns, status breakdown - Decision reviews โ€” a regular rhythm for revisiting decisions that haven't been touched in a while - Experiments with end dates - Hints for missing updates - Updates โ€” see how a decision changed over time - No limits on collections, templates and pinned decisions IT'S FOR YOU IF: - You set goals and want to act in line with what motivates you, not just tick off tasks - You feel like you keep repeating the same mistakes, and finally want to capture them - You keep a journal, but your most important decisions and conclusions drown in daily entries - You want structure that breaks decision paralysis and overthinking - You analyse and overthink a lot, and need a place to organise it - Your priority lists keep shifting, but the history disappears with them. You don't know what dropped off and why, what came back, or which time around this is - You make decisions that shape your life or career, and want to document them deliberately - You feel like you're constantly changing things, but can't see the bigger picture Start for free.
