Everything VivaLyn Can Do.
Voice conversations, AI diary, expense tracking, smart tasks, wellness scoring, medication management, fall detection — and it all works in Hindi. Here's a detailed look at every feature that makes VivaLyn your complete AI life companion.
Speak Naturally. VivaLyn Listens.
VivaLyn is built around voice from the ground up. No menus to navigate, no forms to fill, no buttons to find. Just tap and talk — in Hindi, English, Bengali, Tamil, Telugu, or Marathi. Mix languages freely. VivaLyn understands exactly what you mean.
Natural Voice Conversations
Speak to VivaLyn like you'd speak to a friend. No rigid commands or specific phrases needed — just talk naturally and VivaLyn understands what you mean.
Hindi-English Code-Mixing
Mix Hindi and English in the same sentence — "kal meeting ke baad chai piyi, 150 rupees". VivaLyn understands Hinglish the way real Indians speak.
Contextual Responses
VivaLyn doesn't give generic answers. It uses your conversation history, preferences, and life context to give responses that actually make sense for you.
Instant Voice Actions
Say "remind me to call doctor tomorrow at 10" or "200 rupees auto" and it's done instantly. Voice commands are processed and acted on in real-time.
Your Day, Written by AI.
Most people want to keep a journal but don't have the time or energy to write one. VivaLyn solves that — just talk about your day during any conversation, and it automatically generates a rich, personal diary entry with mood analysis, key events, and reflections. A journal that writes itself.
AI-Written Journal Entries
Share how your day went by voice, and VivaLyn generates a beautifully written diary entry — capturing key events, mood, reflections, and emotional undertones.
Handwritten-Style Format
Every diary entry is displayed in a warm, handwritten-style font that makes your digital journal feel personal and intimate — not like a text document.
Emotional Patterns Over Time
VivaLyn tracks sentiment across your entries — spotting patterns in your mood, identifying triggers, and helping you understand your emotional rhythms over weeks and months.
Private & Encrypted
Your diary entries never leave your phone. They're encrypted on-device and visible only to you. No cloud sync, no server storage, no third-party access.
Say It. It's Logged.
Tracking expenses shouldn't feel like homework. With VivaLyn, just mention what you spent — during a conversation or with a quick voice command — and it's automatically logged with the right category, amount, and date. Scan receipts for larger purchases. See where your money goes without manually entering a single number.
Voice-First Logging
Say "chai 30 rupees" or "auto mein 150 lage" and the expense is logged with amount, category, date, and payment method — all extracted from natural speech.
Bill & Receipt Scanner
Point your camera at any receipt, bill, or prescription. VivaLyn's AI vision reads the document and extracts amounts, items, and categories automatically.
Spending Insights
Get daily, weekly, and monthly breakdowns of your spending. See which categories you spend most on and track your budget progress without any manual effort.
Smart Categories
VivaLyn auto-categorises expenses into 10 categories — food, transport, shopping, health, education, and more. No manual tagging needed.
Tell Your AI. It Remembers.
Forget apps with 20 input fields just to add a task. Tell VivaLyn what you need to do — it creates the task, sets the right date and time, picks the category, and reminds you when it matters. Works with natural language in Hindi and English. Your voice becomes your to-do list.
Voice Task Creation
"Kal 10 baje meeting hai" — task created with date, time, and reminder. Create tasks naturally without opening any app or typing a single word.
Intelligent Reminders
VivaLyn doesn't spam you with notifications. It uses a smart notification system that considers your daily patterns, quiet hours, and notification fatigue before alerting you.
Schedule at a Glance
See your day, week, and month at a glance. Tasks are organised by priority and date, with overdue items highlighted so nothing slips through the cracks.
Smart Task Categories
Tasks are automatically categorised — work, personal, health, finance, errands. VivaLyn learns your patterns and gets better at categorising over time.
Track How You Live. Not Just What You Do.
VivaLyn goes beyond simple habit tracking. It computes a personalised longevity score across 7 dimensions of your wellbeing — emotional stability, routine consistency, social connection, cognitive activity, stress management, sleep regularity, and physical activity. All from data you naturally provide through daily conversations and a quick 30-second voice check-in.
30-Second Daily Check-in
A quick swipeable check-in captures your mood, sleep hours, water intake, and exercise minutes. Or just speak it all at once — "I'm happy, slept 7 hours, had 5 glasses of water and walked 30 minutes".
7-Dimension Longevity Score
Get a personalised longevity score (0–100) based on emotional stability, routine consistency, social connection, cognitive activity, stress management, sleep regularity, and physical activity.
Streaks & Milestones
Build consistency with daily check-in streaks. Hit milestones — 7-day streak, 30-day warrior, 100-day legend — and celebrate your progress with a trophy wall.
AI Wellness Insights
VivaLyn spots correlations between your habits — like how exercise affects your mood, or how sleep quality impacts your stress levels. Get personalised tips based on your actual patterns.
Peace of Mind for the Whole Family.
If you have elderly parents or family members living independently, VivaLyn helps you stay connected and keep them safe. Medication reminders that speak aloud, fall detection using just the phone, voice-activated calling, and gentle social nudges — all designed for people who prefer speaking over typing.
Fall Detection
Using your phone's built-in accelerometer, VivaLyn detects sudden falls with a 2.5G threshold. A 10-second countdown gives you time to cancel — if no response, your emergency contacts are alerted automatically.
Medication Management
Add medications by voice — name, dosage, frequency, and times. VivaLyn sends spoken reminders in Hindi or English and tracks whether doses were taken. Perfect for elderly family members.
Voice-Activated Calling
Say "call Papa" or "Mummy ko phone karo" and VivaLyn finds the right contact and initiates the call. Supports Hindi relationship terms — mummy, papa, bhai, behen, didi, and more.
Social Connection Monitoring
VivaLyn tracks how often someone connects with family and friends. If it's been a while, gentle nudges encourage reaching out — helping combat loneliness, especially for seniors living alone.
Five Personalities. One AI That Adapts.
Not everyone uses AI the same way. A busy professional needs a planner. A senior citizen needs a patient companion. A fitness enthusiast needs a coach. VivaLyn adapts with five distinct persona modes — each with its own personality, tone, and focus areas. Switch anytime with one tap.
Saathi (Companion)
Your everyday AI friend
Warm, conversational, and genuinely invested in your day. Saathi is the default mode — perfect for daily conversations, diary dictation, quick expense logging, and general life management. It remembers your patterns, picks up on your mood, and responds like a friend who actually pays attention.
Best for: Daily conversations, diary writing, general life management
Planner
Structured and precise
Planner mode is all business — clear, structured, and focused on keeping you organised. It creates tasks with deadlines, sets smart reminders, manages your schedule, and gives you briefings about what's coming up. Perfect for professionals who want an AI assistant that keeps them on track.
Best for: Task management, scheduling, professional organisation
Coach
Motivational and goal-oriented
Coach mode encourages healthy habits and celebrates your wins. It tracks your wellness score, reminds you to stay hydrated, encourages exercise, and congratulates you on check-in streaks. Think of it as a supportive buddy who nudges you toward better habits — without the guilt trips.
Best for: Wellness tracking, habit building, fitness motivation
Family Care
Senior-friendly and safety-focused
Designed specifically for elderly family members and caregivers. Family Care mode speaks slowly and clearly in Hindi, uses larger interface elements, manages medication reminders with spoken alerts, enables fall detection, and makes calling family as simple as saying "Beti ko phone karo".
Best for: Seniors, medication management, fall detection, family safety
Journal
Reflective and thoughtful
Journal mode turns your daily conversations into beautifully written diary entries. It asks thoughtful follow-up questions, captures emotional nuance, and creates journal entries that read like literature — not bullet points. Perfect for people who want to reflect on their day but don't have the energy to write.
Best for: Daily journaling, self-reflection, emotional tracking
Smart AI. Zero Compromise on Privacy.
VivaLyn uses advanced AI to understand your life context, generate diary entries, and parse voice commands — while keeping every piece of your personal data on your phone. The server is a stateless proxy that processes your voice and immediately forgets. No accounts to create. No data to hand over. No trade-offs between intelligence and privacy.
Persistent Memory
VivaLyn remembers your conversations, preferences, routines, and life events across sessions. It uses a two-tier summarisation system that keeps your context fresh without storing everything forever.
5 AI Persona Modes
Switch between Saathi (everyday companion), Planner (task-focused), Coach (wellness-oriented), Family Care (senior-friendly), and Journal (reflective). Each persona has a distinct personality and communication style.
6 Indian Languages
Full support for English, Hindi, Bengali, Tamil, Telugu, and Marathi — across voice input, AI responses, and voice output. Switch languages mid-conversation or mix them freely.
100% On-Device Privacy
All your personal data — diary, tasks, expenses, wellness, memories — is stored and encrypted on your phone. The server is a stateless proxy that processes and forgets. Your data is never stored remotely.
One App Instead of Six.
Most people use separate apps for journaling, task management, expense tracking, wellness, and reminders. VivaLyn combines all of these into a single voice-powered companion that understands your life as a whole — not as disconnected data silos.
