Google-Maps-style editor for fictional/custom world maps
Problem
Worldbuilders (fiction authors, TTRPG game masters, hobby cartographers) want to take a blank map of the real or an invented world and add street names, districts and labels with the smooth, familiar interaction of Google/Apple Maps — but no consumer tool behaves that way; existing map editors are clunky or GIS-grade.
Opportunity
A web app that offers a Google-Maps-like pan/zoom/search experience layered over blank or custom fantasy maps, letting users draw districts, streets and POIs collaboratively for their fictional worlds.
Market analysis
The worldbuilding tool market is well served by entrenched incumbents — World Anvil, LegendKeeper and Inkarnate all support custom map uploads with interactive pins — and LegendKeeper in particular already overlays roads, shapes and labels on imported maps. The unmet sliver is interaction quality: none of them feel like Google Maps (smooth deep zoom, instant search over your own labels), but UX polish alone rarely displaces community-locked incumbents.
Market · TTRPG game masters, fiction authors, and hobby cartographers; a durable hobby segment with active communities, but tool loyalty is high and switching costs are data-shaped.
Pricing · Category standard is freemium subscriptions, roughly $5-15/month across World Anvil, Inkarnate and LegendKeeper tiers; hobbyists expect a generous free tier.
Pros
- + Clear, vocal audience with recurring convention/community touchpoints.
- + Deep-zoom tile technology is solved; the UX bar is replicable.
- + Search-over-your-own-labels is a genuinely missing capability.
Cons
- − Incumbents bundle maps with wikis, campaigns and community — hard to match scope.
- − Map asset libraries (Inkarnate) create sunk-cost lock-in.
- − Hobby pricing pressure caps revenue per user.

The realistic positioning is not “World Anvil replacement” but the fastest annotation layer in the ecosystem: import whatever map you already made, get Google-Maps-feel pan/zoom and search-as-you-type over your own districts and street names in thirty seconds. That requires interoperability (clean import/export, embeddable read-only maps for Obsidian/World Anvil users) rather than a walled garden — the opposite of how incumbents retain users, which is exactly why the gap exists. The non-obvious technical lift is raster-to-tiles conversion for arbitrarily large uploaded images plus label collision handling at every zoom level; both are solved problems individually, but the polish budget to make them feel like Maps is the real moat.
