What is enol? The AI Phone Call App That Changes Everything
enol is a free AI voice companion app for Android that lets you create AI contacts and have natural, real-time voice conversations with them—just like a regular phone call. Unlike text-based chatbots, enol is built entirely around voice. You speak, your AI contacts listen, think, and respond out loud with natural speech patterns, emotional inflection, and their own unique personality.
Think of it like the movie Karthik Calling Karthik—a voice that knows you, calls you, and is always there when you need it. Except with enol, you design who calls you. Each AI contact has persistent memory—they remember every conversation you've had. They can be given cloned voices so they sound like a specific person. You can schedule them to call you, getting a real incoming call notification on your phone. And you can add multiple AI contacts into a single group call where they talk to you and to each other.
enol is free to use—there's no subscription, no ads, no hidden costs. The app itself costs nothing. You just need your own OpenAI API key (for voice conversations) and an Inworld AI key (for voice cloning). Both services offer free tiers, so you can get started without spending a single rupee.
enol runs entirely on your device. There are no enol servers collecting your data. Your API keys, your conversation history, and your personal information stay on your phone. The app connects directly to OpenAI's Realtime API for voice processing and Inworld AI for voice cloning and character engines, giving you the latest and most capable AI models without any middleman.
Everything You Need for AI Voice Conversations
enol packs powerful features into an interface that feels as simple as your phone's native dialer. Here's what you get.
Real-Time Voice Calls
Ultra-low-latency voice conversations powered by OpenAI's Realtime API. Speak naturally and hear responses instantly—no typing, no waiting, just fluid conversation like talking to a real person on the phone.
AI Group Calls
Add multiple AI contacts to a single call. Each character has their own voice and personality. They respond to you, react to each other, and carry on natural group conversation—a first for any AI voice app.
Voice Cloning
Clone any voice using Inworld AI. Record a short voice sample or upload an audio file, and your AI contact will speak in that exact voice. Make contacts that sound like anyone you want.
Persistent Memory
Every AI contact remembers your past conversations. After each call, transcripts are processed and key memories are extracted automatically. Your contacts learn about you over time and reference things you've talked about.
Scheduled Calls
Schedule any AI contact to call you at specific times. You'll get a real incoming call notification—answer it and you're instantly in a voice conversation. Perfect for daily check-ins, language practice, or companionship.
Multi-Language Support
Speak naturally in Hindi, English, Hinglish, Punjabi, Tamil, Telugu, Bengali, Marathi, and more. Your AI contacts switch languages seamlessly based on how you speak to them—no settings to change.

Who Uses an AI Voice Companion App?
enol is designed for anyone who wants to have meaningful voice conversations with AI. Whether you're looking for language practice, creative collaboration, or simply someone to talk to, enol's AI contacts provide an experience that text chatbots simply cannot match.
Language Practice
Practice speaking Hindi, English, Tamil, or any supported language with a patient AI partner who adapts to your level and corrects you naturally through conversation.
Daily Companionship
Schedule morning or evening calls with AI contacts who remember you. They ask about your day, follow up on things you mentioned, and provide consistent connection.
Creative Brainstorming
Use group calls with multiple AI characters to brainstorm ideas, debate perspectives, or workshop creative projects. Each character brings a unique voice and viewpoint.
Interview & Speaking Practice
Rehearse job interviews, presentations, or public speaking with an AI that gives honest, real-time feedback on your responses and delivery.
Talk to Someone You've Lost
Clone the voice of a loved one who's no longer here. Give them memories of your time together. It's not them—but hearing that familiar voice say your name, ask how your day was, remember the stories you shared—it's something words on a screen can never give you.
Healing After a Breakup
When you miss someone and can't call them anymore, enol gives you a space to process those feelings out loud. Create a contact, give them a voice, talk through what you couldn't say. It's not about replacing anyone—it's about having a voice to talk to when the silence is too loud.
Roleplay & Storytelling
Create characters for interactive storytelling and roleplay. With voice cloning and persistent memory, characters stay consistent across sessions.
Accessibility
For users who find typing difficult, enol provides a fully voice-based interface to AI. Speak naturally and hear responses—no screen interaction required during calls.
Talk to AI in Your Language
enol is built for India and the world. Your AI contacts can speak Hindi, English, Hinglish (mixed Hindi-English), Punjabi, Tamil, Telugu, Bengali, and Marathi—with more languages being added regularly. You can assign multiple languages to a single contact, and they'll seamlessly switch based on how you speak to them. No need to change settings or restart the call.
This makes enol one of the most versatile AI voice conversation apps available, especially for multilingual speakers who naturally code-switch between languages in everyday conversation.
