Keyboard-first mind maps — Tab-to-add-child, SVG editor with Markdown export

Knowledge workers—product managers, researchers, technical writers and consultants—routinely need to turn outlines and notes into visual maps, but existing mind‑mapping tools are largely mouse-driven, slow for experienced typists, and poor at interop with plain‑text workflows. This creates friction for a large addressable audience: roughly 240 million knowledge workers who together represent a $48.0B annual productivity tooling market (an average willingness to spend of about $200 per person). You could build a keyboard‑first mind‑mapping product centered on predictable Tab-to-add-child and Shift‑Tab-to-promote semantics, an SVG editor for precise layout that preserves semantics, and bidirectional Markdown import/export so maps are canonical in plain text. Add optional LLM features for outline→map conversion and summarize→node automation, an offline mode and a plugin API to integrate with Obsidian/Zettelkasten and other tools used by power users. This market is attractive now because keyboard-centric UX expectations and the plain‑text/Markdown ecosystem are both growing, and AI makes reliable structural conversions feasible; we assess Market Score 85/100 and Revenue Potential 80/100 against medium competition. To stand out you must deliver far faster text-first workflows, exact export fidelity, and deep interoperability rather than another mouse-heavy canvas; realistic challenges are nontrivial UX design for discoverability of keyboard affordances, migration friction from established tools, and building distribution. A pragmatic go‑to‑market is to win power users with a generous free tier and strong Markdown/Obsidian integrations, then monetize teams and enterprise integrations once usage proves the core productivity gains.
