00 / Issue Tree Builder
Build a MECE issue tree, visually.
Drop in your problem as the root question, split it into branches that don't overlap and don't leave anything out, and keep splitting until each one is small enough to act on. Drag to reorganize, flag what's unresolved, export when it's clean.
Free to start. No sign-up required.
01 / What It Does
Everything an issue tree needs, nothing it doesn't.
Drag to reparent
Move a branch onto another node and the whole subtree follows -- reorganize your structure as your thinking changes, no rebuilding from scratch.
Flag the gaps
Mark a branch that's still thin or unanswered right on the tree, so nothing important gets lost once the structure gets big.
Export as text
Turn any tree into a clean, indented outline in one click -- paste it into a doc, an email, or your case notes.

02 / Not Sure Where to Start
New to issue trees? Start with the concept.
What Is an Issue Tree? covers the definition and examples. How to Build an Issue Tree walks through the process step by step. Preparing for a case interview specifically? See case interview prep →. Every split in a good issue tree follows the MECE framework.
03 / FAQ
FAQ
What is an issue tree builder?
A tool for constructing an issue tree: a root question split into MECE branches, each split again until every branch is specific enough to act on. Meceify's builder lets you add, drag, reparent, and flag branches on a visual canvas, then export the result as text.
Is Meceify's issue tree builder free?
Yes. You can build a full issue tree without an account -- it's saved in your browser. Sign in (free) only if you want to save it to the cloud and reopen it from another device.
Can I start from a template?
Yes -- see the case interview starter trees on the case interview prep page for pre-seeded MECE splits (profitability, market entry, market sizing, and more), or start from a completely blank canvas.
Can I export my issue tree?
Yes, as a clean indented text outline, from the toolbar's Export button -- your content, no lock-in.
