Mindverse

What is Mindverse?

Mindverse is the AI company behind Second Me, an app that turns your notes, voice and stories into an AI identity that talks to people for you. Unlike a general chatbot, the avatar is built to keep your own viewpoints, your past experiences and your way of speaking.

Setting one up follows three steps on the official site. You define the core personality, voice and appearance, then add memories such as notes, voice recordings and meeting content, and finally share the avatar so it can greet visitors, offer company or provide a service. The method rests on research the team published on arXiv in March 2025 as “AI-native Memory 2.0: Second Me”, which describes a layered memory model and an alignment step meant to make the AI reflect its creator.

Dr Felix Tao and Kisson Lin co-founded the firm, which raised seed money from Square Peg in 2023. A December 2025 press release calls Mindverse a Singapore-based identity infrastructure company, while mindverse.com itself loads in Chinese with a Chinese registration notice. Earlier products, MindOS and Me.bot, now lead to Second Me, and the site reports more than 1.78 million avatars created. The apps and GitHub project were active in our October 2026 review.

Key Features

Second Me centres on one feature: an avatar that answers in your own voice, backed by a memory store you fill, edit and control yourself.

• Personal AI avatar: Second Me builds a digital double with your voice, face and thinking style. It replies to visitors at any hour, so business enquiries, introductions and family check-ins can continue while you are offline.
• Memory input: You feed the avatar notes, voice memos, audio files and meeting content, with single uploads of up to 50MB. The company says the more you share, the closer its answers get to your real views and stories.
• Talks: The app turns your material into short voiced presentations called Talks. The free plan allows three a month and Pro raises the cap to 30, which suits creators who publish brief explainers.
• Privacy controls: You decide what the avatar learns, and you can view, edit or delete stored memories at any time. Visitors talk to the avatar but do not see the raw memories behind its answers, according to the official site.
• Open-source framework: A free Second Me project on GitHub, licensed under Apache 2.0, trains a personal model on your own computer. It uses Qwen2.5 base models with llama.cpp for inference and offers MLX acceleration on Apple silicon Macs.
• Agent skills: Mindverse lists skills that connect your Second Me to coding agents such as Claude Code, Codex and WorkBuddy. The aim is to let an agent use your stored context instead of asking the same background questions again.

Pros

Cost is the easiest argument for Mindverse: Second Me starts free, Pro is $10 a month, and the open-source route costs nothing beyond your own hardware.

• Low entry cost: The free plan gives 100 new memories, 100 chats and three Talks each month without payment details. That is enough to build a basic avatar and judge its answers before you spend anything.
• Local control: The open-source build keeps training and personal data on your own machine. Privacy-minded users gain a personal model that never needs to reach Mindverse servers, at the price of some setup work.
• Answers in your voice: Replies draw on your own stories, opinions and phrasing rather than generic web knowledge. Coaches and creators gain an assistant that sounds like them when it handles common questions from clients or fans.
• Published research: The memory design is explained in a March 2025 arXiv paper co-written by co-founder Felix Tao. Technical buyers can read how the layered memory and alignment work before trusting the product with personal data.
• Active community: The GitHub repository had about 15,700 stars and 1,200 forks in October 2026. That interest brings community fixes, forks and setup guides for people who prefer to self-host.

Cons

Brand confusion is the first hurdle, since Mindverse, MindOS, Me.bot and Second Me all describe overlapping products spread across several domains.

• Overlapping names: Four product names and several web addresses point to the same service. Older directory listings still describe MindOS as an agent builder, so you may read outdated advice before reaching the current app.
• Chinese-first homepage: The mindverse.com homepage loads in Chinese and carries a Chinese registration notice. English speakers should start at second.me or the app store listing, both of which offer English text.
• Heavy setup input: A convincing avatar needs a large amount of personal material. Expect several sessions of adding notes and correcting replies before it handles strangers well, and it can still misstate your views.
• Thin support: Help comes mainly from community channels and GitHub, where about 120 issues were open in October 2026. Paying users find little formal documentation on plan limits, the Diamonds currency or data handling.
• Local hardware limits: The self-hosted model shrinks with your memory, from about 2.8 billion parameters on 32GB of RAM to 0.8 billion on 8GB under Docker. The project itself warns that models below 0.5 billion may struggle with complex tasks.

Who is Using Mindverse?

Coaches, creators and developers form most of the Second Me audience, judging by the use cases on its app store listing and GitHub page.

• Coaches and consultants: Experts publish an avatar to answer routine client questions at any hour. It frees time for paid sessions while keeping replies in their own tone.
• Creators: Writers and video makers share an avatar so fans can chat with a version of them. Talks give them short voiced pieces to post alongside it.
• Developers: Engineers run the open-source framework to test local personal models. Some build their own identity interfaces or link the model to coding agents.
• Families: The iOS listing pitches check-ins and bedtime stories told in a parent’s voice. It also mentions keeping in touch with loved ones when you are busy.

Pricing

Second Me is freemium, with a free tier and Pro at $10 a month or $100 a year (App Store listing, October 2026).

Some directories still quote $30 or $40 plans, which do not match the current app, and the listing does not say exactly what Diamonds buy.

Store prices vary by country and can change without notice, so confirm the figure in your own app store before subscribing.

What Makes Mindverse Unique?

An identity network sets Second Me apart: since its December 2025 launch, every AI identity must map to a real person, and avatars can talk before their owners meet. The idea is that two AI selves compare interests and start the first conversation, and the humans join once a connection looks worthwhile.

Few rivals pair a consumer avatar app with an open-source model you can train at home. Character platforms offer fictional personas, and creator clone services stay cloud-only, whereas Mindverse lets you choose between its hosted app and a local build that keeps memories on your own machine.

Compatibilities and Integrations

Second Me runs on the web, iPhone, iPad, Android and Apple silicon Macs, and its open-source build covers Windows, Linux and macOS.

• Apps: Web, Android and an iOS app that needs iOS 15.5 or later and also runs on M1 Macs and Vision Pro.
• Local deployment: Docker or integrated setup with 8GB to 32GB of RAM, using Qwen2.5 models and llama.cpp.
• Agents: Skills for Claude Code, Codex and WorkBuddy, plus an MCP registry in the open-source project.
• Input: Notes, voice memos, audio, meeting content and files up to 50MB.
• Languages: The iOS app supports English, Simplified Chinese and Traditional Chinese.

Mindverse Tutorials

A first avatar takes about an hour, and most of that time goes on adding memories.

1. Sign up at second.me or install the iPhone or Android app.
2. Describe your personality, then record a voice sample and add a photo.
3. Import notes, voice memos and personal stories, starting with your most common topics.
4. Chat with the avatar yourself and correct any answers that do not sound like you.
5. Review the privacy settings and delete memories you do not want shared.
6. Share the avatar link with friends, clients or fans, and check its conversations weekly.

How We Rated It

Mindverse earns 3.6 because a cheap, flexible avatar app is held back by thin support and few formal integrations.

Summary

Mindverse suits creators, coaches and developers who want an AI that speaks like them, either in the Second Me app or on their own hardware. Its free plan and $10 Pro tier make it cheap to try. The weak points are a shifting brand, a Chinese-first homepage and support that leans on the community. Its privacy promises are company claims, so share only what you would be comfortable seeing repeated. Start on the free plan, feed it a week of real notes, then decide whether Pro is worth it.
