ObsiKO: AI Markdown + Mindmap

Tired of file conversion and plugin hunting? All your time on settings, not a line written? Features that never talk to each other? Everyday writing, LLM wikis, ontologies, Zettelkasten, mind maps, reading logs, encyclopedias, schedules, file conversion — one app. No login, no payment, no subscription. Obsidian vaults (.md/.canvas/.base) open as-is; AI needs your own API key. ■ Write once, the rest follows · One "color" property colors the note tab, header, tree icon, .base and encyclopedia cards · Type "book" opens a book search that fills the rest in; shelf and dashboard follow · Type "project" adds start and deadline, drawn on the calendar and PARA board · Highlight a PDF; quotes stack up in a same-named note, ready for search · Define your own types and relations: set "author", the other side reads "works" ■ A beautiful cosmic graph · Wiki links, types, relations and PARA form one constellation — more links, brighter star · Filter by relation, or replay how each star was born ■ Infinite mind map canvas (.canvas) · Apple Pencil drawing.
