MarkMemo — The Journal That Remembers Most diary apps treat every entry as an island. MarkMemo connects your moments into a living memory graph powered by AI — so your journal actually gets smarter over time. Capture Everything Your Way Write text, snap photos, record voice, or save web bookmarks. Each entry automatically tags along with weather and location so you always know the full context of your memories. AI That Understands Context Choose from five built-in AI personas — Daily Life, Child Growth, Couple Memory, Travel Diary, and Pet Record — each tuned to analyze entries in context. AI references your earlier entries from the same day for deeper, more relevant insights. Smart Skill Extraction MarkMemo's AI doesn't just read — it structures your entries: - Todos — Automatically extracts tasks with priorities and deadline reminders - Tags & Keywords — Categorizes people, places, projects, and topics - Sentiment Analysis — Tracks your emotional patterns over time - Summaries — Generates concise recaps with key points - Web Summaries — Distills saved articles into digestible notes - Express Pickup — Captures delivery codes from your text Memory Graph Every entry, summary, and extracted entity becomes a node in your personal memory graph. Connections form automatically — temporal, semantic, causal — creating a web of memories you can explore visually. Search by keyword or let AI-powered semantic matching surface forgotten moments. AI-Generated Reviews Daily, weekly, and monthly compression summaries are generated automatically, giving you a reflective overview of your life's arc. Revisit any period and see what mattered most. Multiple Notebooks Organize life into separate notebooks — each with its own AI persona, skill configuration, and memory settings. Work, personal, travel, baby milestones — keep them independent yet equally intelligent. Designed for You Three themes (Classic, Modern, Cute), custom fonts, light and dark modes, six app icon styles, and full support for English, Simplified Chinese, and Traditional Chinese. Your Data, Your Control Export and import your complete journal archive anytime. MarkMemo values your privacy — data stays on your device. Start capturing. Start remembering.
