ObsiKO: AI Note + Mindmap

Tired of converting files or picking plugins? Spent the day on settings and never wrote a line?
Plenty of features, none of them talking to each other?

Everyday writing, LLM wikis, ontologies, Zettelkasten, mindmaps, reading logs, codices, schedules, file conversion — one app, no account or subscription. Obsidian vaults (.md/.canvas/.base) open as-is.
(AI runs on your own API key; with Apple Intelligence on, it can run on the device with no key.)

■ You see it first, before anything changes
· AI rewrites arrive as a suggestion card — nothing changes until you press Replace
· The AI agent works on a copy; only what you pick reaches your notes
· Before the first send to an outside AI, it shows what goes where and sends only if you allow

■ Share to the web, sync between devices (GitHub)
· "Share to the web" publishes a note at one address — theme, tables and images intact, comments too
· The text lives only in your GitHub account, never on our servers; "Stop sharing" takes it down
· Sync runs through your own repository and only ever deletes to the trash

■ Write once, it connects itself
· A "color" property colors the tab, header, tree icon, .base and codex cards. Define your own types and relations too
· Type "book" pops a search that fills the rest; "project" adds start/due to the calendar
· Highlight a PDF and quotes collect into a note of the same name, searchable and on the graph
· Wiki links, types, relations and PARA form one constellation — more links, brighter star

■ Infinite mindmap canvas (.canvas)
· Apple Pencil drawing — turn a sketch into an AI image. Have AI build an editable mindmap, or hand it yours
· Auto-build from a note's links, auto-layout, embeds, groups, relations. 5 styles, 10+ presets. Drop a URL or file to add a card

■ .base files and search
· Projects, kanban, cards, charts, a library (book/paper search), PARA, a budget that pastes receipts. Dataview queries become tables
· Filenames, full text, Korean jamo, semantic search — pin results, bookmark a query, or ask Siri

■ A dashboard and themes you arrange
· 50+ widgets plus query and embed boards — calendars, to-dos, habit trackers, stats. 20+ themes, your own fonts

■ Markdown and a writing helper
· Calm editing tuned for Korean. Format bar and cheat sheet, Mermaid, 20+ charts, inline drawing, video in a note
· 70+ structures across 13 genres (Hero's Journey, Save the Cat, SCQA, character sheets), Socratic questions and style polish
· Spell check, dictionaries, device TTS, a saved assistant role, on-device translation

■ Schedules and viewers
· A date in any file lands on the calendar (Obsidian Tasks compatible) — year/month/week/day, timeline, widget, reminders
· One frontmatter line switches the viewer: book, web novel, messenger, visual novel, codex

■ Clipping and conversion
· The article body and photos become a note, not just the URL — share button or RSS
· One-click Markdown for doc/docx, PDF, hwp/hwpx — one file or a folder; a read-only panel opens dozens more
· Import from Apple Notes, Notion, Evernote, Bear or Logseq — always into a new folder
· Highlight PDFs and Markdown to insert or quote. AI OCR and transcription (labelled by speaker)

■ AI agent
· Add an API key and go (Claude, Gemini, GPT) — the app is complete without one
· Builds mindmaps and .base tables on your phone and reads existing ones. Read-aloud and images in the editor
· File creation, automatic memory, LLM wikis, ontology and Zettelkasten design, MCP. Bulk work is desktop-only

■ Export, images, and everything else
· Marp properties make a deck. Export to PDF, HWPX, DOCX, EPUB, HTML, ZIP, wiki markup
· Dictate on iPhone (on device), Control Center, Lock Screen and Home widgets, Watch quick notes
· Ready for iOS 27 — Markdown round-trips with Apple Notes, the new Siri can add to a note, 4×6 widget
· Image editing, free image search, colors panel, routines, palette, focus timer, screen lock

All of it is free. No account, no payment, a small download.
