Assumptrix is a practical thinking tool for people who want to make better decisions by questioning what they believe.
Every day we act on assumptions — about users, markets, strategies, or ourselves. Assumptrix helps you capture those assumptions, track them over time, and evaluate them with clarity instead of guesswork.
What Assumptrix helps you do
• Make hidden assumptions visible
• Review beliefs regularly instead of forgetting them
• Learn from confirmed and disproven ideas
• Build a habit of evidence-based thinking
Key features
• Assumption tracking
Write down assumptions with titles, descriptions, confidence levels, and tags.
• Confidence scale
Assign and update confidence levels as your understanding evolves.
• Review workflow
Schedule reviews so assumptions are revisited at the right time.
• Clear outcomes
Mark assumptions as confirmed, refuted, or pending — with notes.
• Insights & analytics
See patterns in your thinking, confidence trends, and review history.
• Smart organization
Use tags, filters, and search to manage ideas across projects or life areas.
• Archive & restore
Keep your workspace clean without losing past insights.
• Data export
Your assumptions remain yours — export them anytime.
Who it’s for
• Entrepreneurs and founders
• Product and project managers
• Analysts and researchers
• Strategy and planning professionals
• Anyone interested in structured thinking and self-reflection
Assumptrix doesn’t tell you what to think.
It helps you see what you already believe — and test it honestly.
Think clearly. Learn faster. Decide better.
