Obius — Notes that evolve. Designed for the way you think. Your ideas don't arrive in straight lines. Obius is a visual workspace where notes carry color, ideas connect to each other, and what you wrote yesterday folds into what you're building today. Built for founders, PMs, designers, researchers — and anyone who outgrew Apple Notes but never quite fit into Notion. LOOPS — WRITE ONCE, REUSE EVERYWHERE Drop a Loop into any note — a named, reusable content block like @launch_checklist or @weekly_review. Edit it in one place, every copy updates instantly. Perfect for running lists, shared context, and anything you reference more than once. SECTIONS THAT CARRY MEANING Every section has an intent — a color that tells you at a glance what kind of thinking lives there. Open ideas, questions you're sitting with, work in motion, issues to fix, things that are done. Five colors. Five intents. Your thinking, visible. — Drag and drop to reorder — Collapse, expand, and nest sections — Rich content: text, checklists, code, quotes, images, audio — Tap once to change a section's intent ECHOES — REMINDERS THAT BRING THE NOTE BACK Attach a time-based reminder to any Loop. Unlike calendar pings, an Echo resurfaces the full note when the moment matters — with all its context intact, not a one-line nag. OBIUS INTELLIGENCE AI that lives inside the workspace, not in another tab. — Generate full pages from a single prompt — Edit, rewrite, and refine content in place — no copy-pasting between apps — Smart titles that actually describe the page — Semantic search that finds ideas, not just keywords — Research context: pull what you need, paste, and think from there INSIGHTS THAT SURFACE WHAT MATTERS Obius watches your pages for patterns so you don't have to. Cleanup suggestions, related notes you forgot about, lists hiding in your text, and safety flags for leaked credentials or secrets. VERSION HISTORY, BUILT IN Every note quietly snapshots itself. Browse the timeline, restore any earlier version, watch your thinking evolve over time. No save button. No lost work. SHARE LIVE OR FROZEN Generate a short public link to share a live note that updates as you edit — or freeze a snapshot in time. Readable URLs. View counts. Comments optional. CALENDAR See your work across time. Plan ahead, look back, stay oriented — without leaving Obius. LOCAL-FIRST. PRIVATE BY DEFAULT. — Pages stored on your device first — Works fully offline; syncs when you reconnect — End-to-end encrypted sync — No tracking. No selling data. Not now, not ever. — Optional local-only mode for maximum privacy YOUR MIND. YOUR ARCHITECTURE. Obius isn't another notes app. It's a workspace shaped like thinking — simple enough to start in seconds, deep enough to grow with how you actually work. Designed for the way you think.

Your brain is not broken. Your calendar is. Tempo is the first AI calendar built specifically for ADHD brains. No more staring at an empty calendar. No more forgotten appointments. No more back-to-back meetings with zero transition time. Just talk. Tempo listens. Tempo is a subscription app. A 7-day free trial is included — all features below require an active subscription after the trial ends. SAY IT, FORGET IT, IT'S DONE Open Tempo, hit the mic, and brain-dump everything on your mind: "Schedule a dentist appointment Thursday at 2, oh and I need to call mom, and there's that report due Friday morning..." Tempo's AI understands your chaos. It parses every task, finds the right time slots, and places them on your calendar — with smart buffers between each one. SMART BUFFERS THAT ACTUALLY GET YOU Not every task needs the same transition time. Tempo knows that: • A quick call to mom → 5 min buffer • A deep focus coding session → 15 min prep buffer • A job interview → 30 min prep, 15 min cooldown The AI decides. You just show up. ENERGY CHECK-IN Some days you wake up and can barely function. Tempo gets it. Slide your energy level, pick which events can move, and Tempo reshuffles your entire day — spreading things out on low days, front-loading on high-energy days. No other calendar app does this. VOICE COMMANDS FOR EVERYTHING Already scheduled something? Just say: • "Cancel my dentist appointment" → Gone. • "Move standup to 3 PM" → Moved. No tapping through menus. No editing fields. Just talk. CONFLICT DETECTION Tempo catches double-bookings before they happen. When there's a conflict, tap "Find Another Time" and the AI suggests the nearest free slot. BUILT FOR YOUR ADHD BRAIN • Time blindness? Smart buffers guarantee transition time. • Executive dysfunction? Voice input means zero friction. • Decision paralysis? AI makes the scheduling decisions. • Bad days? Energy Check-In adapts your whole schedule. • Forget to plan? Morning nudge reminds you in 10 seconds.
