Notion, Obsidian, Todoist, Habitica, Day One - you name it. Every single one either wants my credit card, my email, or my data. Some want all three.\n\nSo I built Lexis (lexisapp.xyz) - a free, local-first productivity suite that combines habits, notes, journal, tasks, documents, and an AI assistant into one app. No sign-up. No subscription. All data stays on your device.\n\nWhat is Lexis?\n\nLexis is a web app (also available as a desktop Electron app) that bundles six productivity tools into one:\n\nHabits - Track daily habits with streaks, analytics, and a calendar view\n\nNotes - Rich text notes with full markdown support\n\nJournal - Daily journaling with mood tracking\n\nTasks - Task management with priorities, due dates, and kanban-style organization\n\nDocuments - Create and manage longer-form documents\n\nNoor - An AI assistant powered by three models (Ethos 4.7, Logos 4.5, Verse 4) that can chat, generate images, and help with your productivity data\n\nEverything runs in the browser. Your data is stored locally in IndexedDB. Nothing is sent to any server - not even us.\n\nWhy Local-First?\n\nThe local-first movement is about giving users ownership of their data. When your notes live in Notion's servers, you're at the mercy of their pricing, their uptime, and their privacy policies.\n\nWith Lexis:\n\nYour data never leaves your device\n\nNo account needed - just open the app and start using it\n\nWorks offline - full functionality without internet (except AI features)\n\nGDPR compliant by design - we literally can't see your data because it never reaches our servers\n\nThe AI Assistant (Noor)\n\nI wanted an AI that feels like it's yours, not a corporate chatbot. Noor is Lexis's built-in AI assistant with three models:\n\nEthos 4.7 - the creative, conversational model\n\nLogos 4.5 - the analytical, precise model\n\nVerse 4 - the fast, efficient model\n\nNoor can chat with you about your tasks, habits, and notes. It can generate images. Voice dictation runs through your browser's built-in speech recognition — no cloud transcription needed.\n\nTech Stack\n\nNext.js 15 with App Router\n\nTypeScript throughout\n\nTailwind CSS for styling\n\nFramer Motion for animations\n\nElectron for the desktop app\n\nIndexedDB for local storage\n\nNVIDIA API for the AI models\n\nVercel for hosting\n\nTry it: lexisapp.xyz - no sign-up, no credit card, just open and use.", "url": "https://wpnews.pro/news/why-i-built-lexis-a-free-local-first-ai-productivity-suite", "canonical_source": "https://dev.to/lexis_workspace/why-i-built-lexis-a-free-local-first-ai-productivity-suite-21bp", "published_at": "2026-09-03 18:36:32+00:00", "updated_at": "2026-09-03 18:55:14.123942+00:00", "lang": "en", "topics": ["ai-products", "developer-tools", "artificial-intelligence"], "entities": ["Lexis", "Noor", "Ethos 4.7", "Logos 4.5", "Verse 4", "NVIDIA", "Next.js", "Vercel"], "alternates": {"html": "https://wpnews.pro/news/why-i-built-lexis-a-free-local-first-ai-productivity-suite", "markdown": "https://wpnews.pro/news/why-i-built-lexis-a-free-local-first-ai-productivity-suite.md", "text": "https://wpnews.pro/news/why-i-built-lexis-a-free-local-first-ai-productivity-suite.txt", "jsonld": "https://wpnews.pro/news/why-i-built-lexis-a-free-local-first-ai-productivity-suite.jsonld"}}
