BoardSnap is an iOS app that reads a whiteboard mind map — central node, branches, sub-branches — and converts the radial structure into a hierarchical text outline in one snap.
Mind maps are one of the best brainstorming tools because they resist the tyranny of linear thinking. Starting from a central idea and branching outward lets you follow associations without committing to a structure prematurely. On a whiteboard, a mind map can grow organically — you add a branch, realize it should be a sub-branch of something else, and physically draw the connection.
The problem is that a whiteboard mind map is radial and physical. The output you need is usually hierarchical and digital — an outline for a document, a set of categories for a spreadsheet, a set of topics for a presentation structure. Converting radial to hierarchical requires reading the board, interpreting which branches are primary and which are secondary, and re-entering everything in the new format.
For large mind maps with four or five levels of branching, this is a 30-minute job. For the most complex maps — the ones where the thinking is richest — it's the most tedious job.
One word or short phrase. Circle it. This is the root of the mind map. Everything branches from here. Make it large — it should be the biggest text on the board.
From the center, draw five to eight branches outward. Each branch ends in a main topic. Write the topic label at the end of the branch. Main branches can be in different colors if you have multiple markers — color helps BoardSnap distinguish branch families.
From each main branch, draw secondary branches for subtopics. Each secondary branch ends in a label. Three to five sub-branches per main branch is readable on a whiteboard. More than that and the map gets dense — split onto a second board.
For areas that need more detail, draw tertiary branches from the secondary ones. Write specific ideas, tasks, examples, or questions at the ends of these branches. Third-level branches are where the real thinking lives.
If an idea on one branch connects to an idea on another, draw a dashed line between them. Cross-connections are where the most interesting insights in a mind map live — they show non-obvious relationships.
Open BoardSnap. Step back to get the full radial structure in frame — the center and all branches should be visible. BoardSnap AI reads the radial layout, determines hierarchy by proximity and branching direction, and produces the hierarchical outline.
A hierarchical text outline with the central idea as the title, main branches as top-level headers, sub-branches as second-level bullets, and third-level branches as nested bullets. Cross-connections are described as relationship notes at the end of the relevant items. The outline is paste-ready into a document editor, presentation tool, or task tracker.
The marketing team mind-mapped content topics for the quarter. Central idea: 'Content that drives signups.' Eight main branches (use cases, comparisons, tutorials, case studies, etc.), thirty-two sub-branches. BoardSnap produced a content calendar skeleton — the branch structure became the editorial categories.
A writer used a whiteboard mind map to brainstorm the structure of a long-form article. Central idea: the thesis. Main branches: the key arguments. Sub-branches: supporting evidence and examples. BoardSnap's hierarchical outline became the first draft structure.
A PM led a feature brainstorming session with the team. Central idea: 'Onboarding.' Main branches for each user segment (new user, power user, team admin). Sub-branches for each feature idea per segment. BoardSnap read the branching hierarchy and produced a feature list organized by segment.
It depends on legibility. A mind map that fills a 4x8 whiteboard with text at different orientations — some written along branch angles — is harder to read than one with text written horizontally at the end of each branch. Write branch labels horizontally and leave space between branches for best results.
Yes. Crossing branches are one of the more complex visual cases, but BoardSnap AI uses branch endpoints and directionality, not just line paths, to determine the hierarchy. Clear, labeled branch endpoints help significantly.
Sticky notes work well. Position them at the end of the branch they belong to, or draw a short line from the branch to the sticky. BoardSnap reads sticky note content and its proximity to the nearest branch to determine its position in the hierarchy.
The BoardSnap output is plain text in outline format. Most mind mapping apps can import a text outline. Check your app's import options for 'text outline' or 'OPML' format.
