Search that reads everything
Titles, text, PDFs and the words in photos: in English, Chinese and Japanese, even by pinyin.
筆記
Notes that stay on your devices.
Hikki is a block editor for iPhone, iPad and Mac. Every page is a file in a folder you choose, so your writing never waits on an account or a server.
筆記 (hikki) is Japanese for taking notes. Hikki shows readings like that above the kanji in your own pages.
Your notes are files.
Each page is one small file in a folder you pick: on the device, or in iCloud Drive to reach every device you own. Copy it, back it up, read it with any tool. Hikki keeps a search index beside it and can always rebuild it from the files.

Open the app and write. There is nothing to sign up for.
Works offline
Everything is on the device first; the network is optional.
Syncs through iCloud Drive
Put the folder there and your other devices pick up changes.
Nothing is overwritten
Two devices editing one page keep both versions, side by side.
Thirty days of history
Go back to how any page read last week, and restore it.
One app for iPhone, iPad and Mac.
Built natively for each, with the same pages everywhere.
Put the folder in iCloud Drive and what you write on one shows up on the others. Two devices editing the same page keep both versions.
Two pages side by side.
Drag a page from the sidebar to the edge of the window and it opens beside the one you are writing in. Each side has its own editor.
Keep notes on one side and the source on the other, or a PDF from the page. Open the same page twice to write in one half and read in the other.
AI that works on your page, not around it.
Ask about what you are reading, or select a passage and have it rewritten. It runs on your own OpenAI or Anthropic key, and nothing is sent until you ask.
Ask beside the page.
The AI panel reads the page you have open and the passage you selected. Add other pages with @, attach a picture or a PDF, and let it search the web, with its sources linked.
Select, ask, review.
Improve the writing, make it shorter, change its tone or translate it. The change shows in the page, struck through and added, and nothing is replaced until you accept it.
Write in blocks.
Type / for headings, to-dos, tables, toggles, callouts, code and math. Drag any block by its handle, or drop it beside another to make columns.
Readings for kanji
Select a word and Hikki suggests its furigana, then sets it above the text.

Page history
Every editing session keeps the version before it. Compare them word by word.
Comments
Comment on a passage; the thread travels with the page.
Lock a page
Lock a finished page and nothing in it changes by accident, on any device.
Markdown in, Markdown out
Import Markdown, HTML and text files or whole folders. Export a page or everything as Markdown, HTML, PDF or the original files.
Editing together is on its way.
Share a page and write in it with someone else, at the same time. It is in development now, built on the same files, so your notes stay yours.
