Mhisper is a quieter place to think. Your thoughts become bubbles — softly lit, gently drifting on a starfield — alive until you're ready for them. No streaks. No guilt. No inbox pretending to be a mind. Just a calm sky where what you're thinking becomes something you can see. CATCH IT • Type a thought, or speak it — on-device dictation turns your voice into a bubble before the idea fades • Every thought wears a colour. Choose yours, or pick Rainbow and let each new thought arrive in its own • Made for the shower sentence, the walk-home idea, the 2am worry that just needs somewhere to land BUILD IT • Step inside any thought — it opens into a full note built from blocks: clean Markdown or richly styled Fine Text • Add tasks with deadlines and gentle reminders, so remembering isn't your job anymore • Add tasks and check them out from in the note body itself. • Attach images and files where they belong • Connect your notes with one another using threads , and mention other notes in the note body to easily click to navigate between connected notes. SEE IT • Zones gather related thoughts into glowing regions of the sky • Threads draw quiet lines between ideas that belong together • Clusters fold a whole project into a single constellation — step in, step out • Search by word or colour when you need one thought fast SHARE IT • Presenter mode turns a note into a slow, beautiful reading — like you're speaking to the reader, one passage at a time • Share a note with a link, or open a Shared Space where a family, a book club, or a team keeps one sky together KEEP IT • Your notes are your intellectual property. Mhisper never reads, sells, or trains anything on them — they exist for you and no one else • Save your whole canvas as an encrypted memory file only you can open • Your sky follows you between iPhone and the web at mhisper.app For the racing mind that thinks in every direction. For writers watching scenes find their shape. For students turning reading into understanding. For families keeping memories where the grandkids can wander through them. Mhisper is free. Open it, Mhisper a thought, and watch it land.

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.

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.
