About

Kihya Memo

Features
Read full description

Kihya Memo is a lightweight, offline-first Markdown notepad. Write the source directly, use focused formatting tools, and switch to a beautiful native preview while every note remains a file you can keep. Markdown is the heart of the app. When needed, the same plain-text editor also opens safe UTF-8 text and source documents without converting them to a proprietary database. There is no Kihya account to create and no required Kihya memo server. Google Drive sync and remote server folders are optional. KEY FEATURES โ€ข Switch instantly between Markdown source and native preview โ€ข Toggle task checkboxes directly in preview โ€ข Use focused Markdown tools for headings, lists, bold, italic, strike, code, links, attachments, and underline โ€ข Convert pasted rich text into clean Markdown โ€ข Create, edit, rename, move, and share HTML, JSON, XML, CSV, PHP, ASP, JavaScript, SQL, and other UTF-8 text or source files when needed โ€ข Live syntax colors and line numbers without adding formatting to the file โ€ข Static HTML/SVG, pretty JSON/XML, table, calendar, contact, and color-source previews โ€ข Plain-text copy and paste for code; rich-text conversion only inside Markdown โ€ข Import photos, PDFs, archives, and other files from Photos or Files โ€ข Drag, rename, move, and safely remove nested folders in a dedicated manager โ€ข Search file names and full note contents โ€ข Find, Replace, and Replace All from the title menu, with case options, regex, and capture groups โ€ข Choose Save, Discard Changes, or Keep Editing when leaving an unsaved note โ€ข Move, rename, trash, or open past versions from the title menu โ€ข Open Recently Deleted from the folder list to restore items to their original location or delete them permanently โ€ข Optionally protect Recently Deleted with Face ID, Touch ID, or the device passcode โ€ข Keep pre-save versions locally and load one into the editor without saving it immediately โ€ข Recover the latest local edit draft after an unexpected app termination โ€ข Optional marker-texture highlighting for bold and underlined preview text โ€ข Preview local images and open clearly marked local-file links โ€ข Open and share editable text, source documents, and stored files through the system Files app โ€ข Optionally sync original files through a visible app folder in your own Google Drive โ€ข Add SFTP, plain FTP, explicit FTPS, or implicit FTPS servers as remote folders, with local recovery drafts, history, conflict detection, and verified saves โ€ข Export the visible folder tree as a ZIP without trash or private history โ€ข Start writing instantly from a resizable Quick Note Home Screen widget โ€ข See a sourced daily thought matched to morning, afternoon, evening, or night โ€ข Continue writing beneath a thought and share it as a 4:5 image card โ€ข Open a favorite document in full-screen reading mode from the Home Screen โ€ข Five bundled Korean typefaces in addition to the system font โ€ข Native phone navigation and an iPad three-pane or full-screen editor PRIVACY BY DESIGN โ€ข No Kihya sign-up or required login โ€ข No ads or cross-app tracking โ€ข Google Drive connects only when you choose it; notes are never sent to a Kihya server โ€ข Remote connections go directly from your device to the server you enter; credentials use device-only protected storage and remote contents, hosts, paths, and user names are excluded from analytics โ€ข SFTP and FTPS are encrypted. Plain FTP is visibly marked and requires a separate warning because its credentials, file names, and contents are not encrypted โ€ข Firebase usage events never include note text, file names, searches, or Google account details โ€ข Access is limited to local files and files the user explicitly selects โ€ข Normal history and recovery drafts stay on device; pre-overwrite sync text is also protected in hidden app data in your Drive
