Read full descriptionHide full description
Notes, tasks, voice captures, attachments, and AI recall usually end up split across different apps. WashiNote brings them back into one calm, local-first workspace built for iPhone, iPad, and Mac. Write in Markdown with a focused editor that stays readable as your notes grow. Keep headings, tags, inline images, and long-form writing in one place without turning your workflow into a cluttered document system. Plan work in the same library where you write. WashiNote keeps notes, tasks, and projects connected, so quick ideas, scheduled tasks, and larger project material do not drift apart. Capture more than text: - Record meetings and turn speech into editable note text - Attach PDFs, text files, HTML, images, and audio - Import readable content for search and AI workflows - Save web material through browser sharing flows Recall what you saved: - Search across notes, tasks, projects, and attachments - Use AI to retrieve, summarize, and organize what matters - Build read-only knowledge pages from your own material - Keep related ideas visible through connected context Stay local-first by default. Core writing, planning, capture, and AI workflows work without turning the app into a cloud-dependent workspace. When you want more portability, Pro unlocks iCloud sync across devices, note export, purchase restore, and encrypted `.washi` backup tools. WashiNote is built for people who want a quieter, more durable way to think: one workspace for writing, planning, capturing, and finding things again.
