ObsiKO: build your own universe of notes.

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. The app is complete without it.)

■ 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, asks before deleting several files, uses only 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 and PARA
· Highlight a PDF and quotes collect into a note of the same name — searchable, on the graph
· Wiki links, types, relations and PARA form one constellation — more links, brighter star

■ Infinite mindmap canvas (.canvas)
· S Pen and stylus 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 make 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 in one tap
· Filenames, full text, Korean jamo, semantic search — pin results to the sidebar, bookmark a query

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

■ Markdown and a writing helper
· Format bar and cheat sheet, Mermaid, 20+ charts, inline drawing, embeds, video in a note
· 70+ structures across 13 genres (Hero's Journey, Save the Cat, SCQA, character sheets), Socratic questions, critique and style polish
· Spell check, dictionaries, unlimited 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, nothing overwritten
· Highlight PDFs and Markdown to insert or quote. AI OCR and transcription (meetings 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 folder design

■ Export, images, and everything else
· Marp properties make a deck. Export to PDF, HWPX, DOCX, EPUB, HTML, ZIP, wiki markup
· Dictate on your phone (recognised on device), six home screen widgets, save straight from any app's share sheet
· Image editing, free image search, colors panel, routines, command palette, focus timer, screen lock ## Rankings - #2,453,086 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.INTERNET` - `android.permission.MODIFY_AUDIO_SETTINGS` - `android.permission.POST_NOTIFICATIONS` - `android.permission.RECEIVE_BOOT_COMPLETED` - `android.permission.RECORD_AUDIO` - `android.permission.USE_BIOMETRIC` - `android.permission.USE_FINGERPRINT` - `android.permission.WAKE_LOCK` - `com.android.vending.CHECK_LICENSE` - `com.obsiko.app.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` ## Similar extensions and apps - [Nodeza](https://chrome-stats.com/d/com.yourcompany.nodeza) — 28 users - [KoiNote](https://chrome-stats.com/d/com.zhiplus.note) — 4 users - [Aimpath - Mindful Notebook](https://chrome-stats.com/d/com.lcs.sudopad) — 5,247 users - [Obsidian](https://chrome-stats.com/d/md.obsidian) — 6,000,376 users, 4.39 / 5 - [Clone+: Notes, Memo, AI](https://chrome-stats.com/d/com.tdlab.clone_plus) — 78 users - [NoteCraft - Notes & AI Writer](https://chrome-stats.com/d/me.fapp.notecraft) — 45 users - [Mindskribe](https://chrome-stats.com/d/com.mindskribe.mindskribe) — 11 users - [Magicso - AI Note Assistant](https://chrome-stats.com/d/com.chuan.ainote) — 6,098 users - [Cortex: AI Second Brain](https://chrome-stats.com/d/com.enesy.bookmarker) — 156 users - [SmartNote AI](https://chrome-stats.com/d/com.cybrainx.smartnoteai) — 3 users - [Ownmind Simple Notes & Journal](https://chrome-stats.com/d/com.ownmind.app) — 38 users - [AI Notes – Second Brain](https://chrome-stats.com/d/com.somnathtechnolabs.ainotes) — 7 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.obsiko.app)
