RealSoul — AI Human Companion
What RealSoul is, how it differs from AniSoul, how to get started, what stays on your device, and what to expect from a real-time 3D companion.
RealSoul
RealSoul is a real-time 3D companion rendered in a photorealistic style — lifelike skin, hair and expressions, animated live on your device and responding as you talk. Her language model, her voice and her lip-sync run on the device too, so your conversations stay on it.
RealSoul or AniSoul?
The two apps are built around the same idea and offer the same kinds of interaction. The difference is the art direction:
| RealSoul | AniSoul | |
|---|---|---|
| Style | Photorealistic | Anime |
| Wardrobe | Everyday wear through dressed-up looks | Traditional wear through casual cosplay |
| Everything else | Voice conversation, lip sync, expressions, moods, personas, hairstyles, on-device AI | The same |
Pick by which look you want. They are separate apps and separate downloads, so trying one does not commit you to it.
Getting RealSoul
RealSoul is published on the App Store and on Google Play.

The App Store and Google Play listings are authoritative for device compatibility and regional availability.
RealSoul is free to use every day, with a daily message allowance: 30 messages a day at the time of writing. RealSoul No Daily Limit, an optional subscription, removes the daily limit and changes nothing else. Free Messages, Subscriptions and Restoring Purchases covers prices, renewal and cancelling.
Getting started
- Install from the App Store or Google Play and open the app while you are on Wi-Fi.
- Let her model arrive. Her language model is fetched once. On newer versions of iOS the system fetches it in the background; otherwise RealSoul downloads it on first launch and shows you the progress. Until it is in place she can speak but cannot yet hold a conversation — on a first launch that is expected, not a fault. There is no account to create.
- Talk or type. Speak naturally and she listens, replies in her own voice, and lip-syncs while speaking. Voice is full duplex: cut in mid-sentence and she stops to listen. Typing works too if you would rather not use voice.
- Set the scene. Give her a persona and mood; she stays in character with you.
- Style her. Pick the character, her hairstyle and the outfit you like.
The first time you use voice, iOS asks for two permissions: the microphone, and speech recognition (RealSoul uses Apple's on-device recogniser). Approve them from the system prompt only. If you decline, you can still use the app by typing.
What to expect from your device
Photorealistic real-time rendering, with a language model running on the same device, is the most demanding thing either companion app does. Before judging performance, know what is normal:
- It uses real GPU work. Sustained use warms the device and drains battery faster than a chat app does. This is expected, not a defect.
- Realistic rendering costs more than stylised rendering. On the same device, expect RealSoul to work the hardware harder than an anime-styled companion does.
- Older devices work harder. Near the minimum requirement, expect lower frame rates, especially once the device warms up during a long session.
- Background rules apply. iOS suspends apps in the background; a session resumes rather than continuing to run while you are elsewhere.
If rendering becomes choppy during a long session, letting the device cool usually restores it. Closing other demanding apps helps too.
What stays on your device
Her language model, her synthesised voice and her lip-sync run on your device, and speech recognition uses Apple's on-device recogniser. Your conversations, your microphone audio, your prompts and her memories never leave the device, and no third-party cloud AI is involved. Once her model is in place, a whole conversation works in Airplane Mode.
The app sends only three things, all to our own servers:
| What | Why |
|---|---|
| A device identifier provided by iOS | To meter your free messages for the day |
| A count of messages sent | The same |
| Your App Store receipt, once you subscribe | To validate and restore the subscription |
None of it is sold or used for advertising or cross-app tracking. The details are in the privacy policy.
The other side of keeping everything on the device: there is no account and no copy on our servers. If you delete the app or move to a new phone, your conversations do not come with you. Restore Purchases in the app brings back a subscription, through your Apple Account; it does not bring back conversations.
Getting help
Use the support page or email service@allianceinterstellar.com. Include your
device model, iOS version and app version — for rendering or performance reports those three
determine almost everything.
