From RLHF to RL'ME'F

When AI stops being a general-purpose tool and becomes your digital twin

Preface: When memories evolve from indexed fragments into a reasoning-capable, evolvable parameterized network through temporal training, the core mission of knowledge engineering shifts from “What is true?” to “What is ME?”, marking the tipping point where knowledge graphs transcend universal cognitive infrastructure to embrace personalized mind science. This exploration is fundamentally an experiment in human cognition, and our research on entity relationships and dynamic graphs may hold the key to unlocking it.

Me.bot leverages personalized individual data rather than generalized human data. In this emerging social paradigm, before you and I meet in person, let our bots, embodying our unique cognitive spirits, converse first.


Vision Behind the Product 🍅

Tao Fangbo, founder of Mindverse, introduced their product Me.bot - Your AI Second Brain in an interview:

“Me.bot goes beyond RAG or long-context knowledge retrieval. It trains personalized models based on user memories to deliver proactive, individualized insights. Our goal is to step back from the world and step closer to the individual.”

While ChatGPT and Deepseek compete over general-purpose intelligence, Mindverse is betting on the opposite axis: a dedicated “me” for every user, not a lifestyle assistant, but a digital extension of the self. The bet compresses into one sentence: rather than predicting the next token, predict your next thought.

The claim is testable, and Tao offers an anecdote as evidence. Mindverse trained his personal Me.bot, and on his 35th birthday it generated a statement nearly identical to his own words: “I’m Tao Fangbo, founder of Mindverse. Today, as I reflect on my 35th birthday, I’m deeply grateful for the decision I made at 30; it was unequivocally right.”

Asked how this is achieved, Tao’s answer was one word: “Memory.” Human memories are the ultimate dataset (dense, longitudinal, and unique to one person), and they make it possible to predict the flow of an individual’s cognitive river.


Me.bot and Shared Memory 🍅

The architectural distinction matters here. Traditional AI memory systems (RAG, long context) treat memory as external data to be retrieved: the model stays generic, and personalization lives in what gets fetched into the prompt. Me.bot instead parameterizes user memories, internalizing lived experience and cognitive patterns into the model’s weights. The design echoes neuroscience’s axiom that “memory shapes identity”: once an AI can predict the “next thought” from temporal life data (what you hear, see, and contemplate), it stops being a reactive tool and becomes a cognitive digital twin.

The key differentiator is the temporal training framework. Where large language models freeze their parameters for months at a time, Me.bot emulates human growth: just as the brain consolidates memories during sleep, Me.bot compresses each day’s experiences into updated parameters nightly. Tao frames the alignment consequence sharply: “RLHF (Reinforcement Learning from Human Feedback) aligns AI with humanity’s collective interests. But my personal model must align with my individual interests; this is the shift from RLHF to RL’ME’F.

Tao is equally direct about what he sees as the limits of mainstream agent frameworks (Coze, Workflow-style systems): they are “scaffolding external logic,” assembling intelligence out of externally wired steps. An agent that answers a complex request by decomposing it into a fixed pipeline (an eight-step method, say) accumulates error at every step, and the failure rate compounds. Contrast that with the brain’s “subconscious validation mechanism”: humans continuously adjust their path mid-action rather than mechanically executing a preset plan. Me.bot’s answer is “endogenous training” under a “time-for-intelligence” framework: serve requests during the day via RAG, retrain on the day’s new data at night, so memory and model capability evolve in sync. The brain-like learning loop (RL’ME’F) is what lets the system adapt dynamically instead of leaning on static rules.

On hallucination, Me.bot takes a deliberately contrarian position: hallucination is “a symbiosis of creativity and risk”: “only with hallucinations can there be imagination, divergence, and intelligence.” Rather than suppressing it, the design constrains it with two mechanisms:

  • A lateral monitoring mechanism, a subconscious-like validation program that continuously checks whether the AI’s actions still align with its goals;
  • Parameterized constraints, internalizing the user’s values into the model as “thought boundaries,” so hallucination stays controllable and serves personalized goals rather than undermining them.

Features 🍅

“While global users email themselves files, Chinese users rely on WeChat file transfer assistants. Me.bot systematically rescues these drowning memories.”

Me.bot’s core function is connecting life’s scattered dots, reviving the artifacts buried in WeChat collections and similar dumping grounds. Users can input links, files, images, and audio, or import from Notion, Evernote, Apple Notes, Markdown apps, and email. Text entries tagged ‘Todo’ auto-convert to smart reminders, with timestamps parsed for precise alerts. The user’s conversation history with Me.bot itself also feeds back into the training data.

When a memory is added, Me.bot processes it for roughly two minutes. The output of that thinking pass is twofold: highlights, which summarize and organize the memory’s content, and connected memories, which link it to historical entries in search of deeper patterns: what is the user currently studying? What are they drawn to?

Me.bot also turns processing into dialogue. It poses thought-provoking questions back to the user, such as “What is the fundamental difference between the models you have browsed?” or “How will personalized AI change our way of life?”, designed to pull the user into reflection and surface new questions worth discussing.

Once processed, the memory lands in Me.bot’s Library, tagged with categories such as ‘Tech’, ‘Business’, or ‘Personal Growth’. Beyond the chronological stream, the Library offers a second organization by topics, types, and sources. Topics include Tech, Moments in Life, Self Growth, Art & Design, Business, and so on, auto-tagged during processing, but users can also define and apply their own topics, which keeps the taxonomy flexible rather than imposed. Type categories (schedule reminders, image storage, link storage) group memories by functional property, which pays off when hunting for a specific kind of information: checking upcoming tasks means simply opening the To-dos category.

There is also a dedicated Discover section, with two daily pushes at 9:00 and 19:00. The cards are grounded in the user’s own inputs (knowledge sharing in technology, book recommendations), and Me.bot invites the user to discuss them.

Asked for insights over recently stored memories, Me.bot produces a review of recent readings and links that goes beyond textual summary, adding imagination and association, for instance concrete application scenarios for a technology the user has been reading about.


Future Outlook 🍅

Tao’s long-range claim is that the personal model should become an “AI identity,” a new type of agent through which humans interact with the world. The distinction he draws is between mimicry and internalization: the AI identity does not simply imitate user behavior; it absorbs the user’s values and decision logic deeply enough to form a self-evolving “digital mind.” And when that identity is fully owned and defined by the user, technological power shifts from centralized platforms to individuals, from general-purpose to personalized, toward what he calls true “AI equality.”

“We can expect that in the future, when discussing business, perhaps your me.bot and my me.bot can chat first.”

Alongside Asimov’s Three Laws of Robotics, Tao proposes his own “Tao’s Three Laws”:

  1. Super “love” alignment (i.e., AI should have love for humans);
  2. AI should be relevant to humans, reflecting each individual’s will;
  3. AI should provide a mindful experience.

The third law is a product stance as much as a principle. Tao wants Me.bot to feel comfortable to use, unlike the “mental opiates” that dominate the market by seizing attention and time. His bar is simple: “something that doesn’t make you regret spending two hours on the app after using it.” He likens the mindfulness he is after to “clean water,” “fresh air,” or “being in the forest.”

Asked whether an AI-native memory-built “second me” could enable digital immortality, Tao identified himself as “human-centric” and gave an answer few founders in this space would: the greatest invention in the world is death. Digital immortality after a human life fades raises ethical questions our society is not prepared for, and he intends to avoid it rather than fight death.

“Life itself is an amusement park; first, you need to figure out what game you want to play, and second, play it with love. I think that’s the most important thing.”

The answer distills the project’s core conviction: AI should not replace humans, but extend them.
