A personal library for everything worth remembering. Mind Archive is an aesthetic notes app that organises your journals, PDFs, recipes and ideas as beautiful books on your own shelves. A calm, private place for what actually matters to you. Not another notes app you'll abandon in a month. A library you'll actually want to open. YOUR PERSONAL LIBRARY Every note is a book. Every book sits on a shelf. Every shelf lives in a bookcase you design yourself. Organise your journal, recipes, reading notes, travel plans, work projects and daily thoughts the way you naturally sort what you care about — no folders, no tags, no complicated systems to learn. EIGHT WAYS TO REMEMBER Choose the right kind of book for what you're capturing: - Notes with rich text, checklists, images and file attachments - Journals with dated entries for reflections and gratitude - Recipes with structured ingredients and step-by-step method - PDFs that remember your last read page and bookmarks - Photo albums you can reorder and swipe through - Voice memos grouped together in one place - Files you can open with any app - Links you want to come back to THE NOTICEBOARD A beautiful cork-board canvas for quick captures and gentle reminders. Pin posters with photos, colours, patterns or text — set optional reminders that fire when you need them. Perfect as a family fridge board, mood board, weekly planner, or a home for the little things that don't need a whole book. SYNC EVERYWHERE Start writing on iPhone and pick up on the web at mindarchive.io. Your library stays perfectly in sync across every device. Local-first architecture means it works offline too — your library is always yours, always to hand. MAKE IT YOURS Design a library that feels like yours.
