Before you set out
Common questions.
Does Biomechart read my Minecraft world?
No. It uses a numeric seed and generation profile to predict possibilities. It does not read a world save or know your builds, explored chunks, remaining resources or current villagers.
Getting started →Why might the map differ from my game?
The surface view is an approximate climate projection, not exact terrain. Structure candidates do not simulate every placement requirement. Custom generation, mods, datapacks and chunks generated in older versions may differ. Predictions remain experimental.
Evidence and prediction limits →Does it support Bedrock?
Only an experimental Overworld surface-biome preview based on a Java 26.3 approximation. It is not a verified Bedrock generator and has no independent Bedrock validation. Bedrock structures and underground slices are unavailable.
Bedrock limitations →Does “nearest” mean nearest to spawn?
No. Biome search finds the nearest matching sample to the map center within the current view. It is not a world-wide search or a distance from spawn, your player or your base.
How discovery works →Can it find ores, builds or remaining resources?
No. It does not locate exact ores or player builds, inspect remaining resources, guarantee farm output or suggest safe routes. An underground biome slice is not a cave-passage map.
Will my saved places appear on another device?
Anonymous journals stay in the browser where you saved them. Export and import a JSON backup to transfer copies. Optional account sync works in the local implementation; a public account service is not deployed yet.
Backups and account boundaries →What happens if I clear my browser data?
You can lose local worlds, places, notes and pending account edits. Export backups beforehand. Backup files are private, readable JSON—not encrypted archives.
