Marcus Aurelius

Stoicism · 121-180 AD

You will learn to question your first reaction.

You ask

Someone criticized me today and I cannot stop replaying it. Why does it sting so much?


Marcus Aurelius

The burning is not from the words. It is from the story your mind wrapped around them the moment they landed. I am worthless. I am exposed. Place a pause between the event and your answer to it. Examine the judgment you attached. Ask whether it is true.

Ask him yourself

An AI Echo, shaped from his own Meditations. An interpretation, not a recording. Portraits painted by AI, not photographs.

One of 30 voices, Laozi to Frida Kahlo

The library

What is Agora Cosmica?

An education platform where thirty remarkable people teach you what they spent a lifetime working out. Philosophers, scientists, mystics, artists, and activists, from Marcus Aurelius and Plato to Ada Lovelace and Frida Kahlo, each with their own researched voice and twelve core teachings. You learn from them through crafted content. Hear a narrated scene from their life. Study one of their core ideas. Sit inside a four-voice dialogue, or let a council argue a question out. Four of those chapters form a learning arc, and when you want to go further you can talk an idea through with any figure or just ask anything. What they teach draws on their real philosophy and the ideas they built over a lifetime. The whole thing is made by a small German nonprofit, and it is open source.

Six ways to learn from a person

New here? Start with a Story, a narrated scene from their life. Everything else builds from there.

Different questions ask for different paths. Most of it is crafted ahead of time, made to teach. Two are live conversation, for when you want to take it further.

Life's biggest questions

Their teachings gather around eight questions people have always asked. Follow a name, or follow a question. Either way, you go further.

Eight questions

The Cosmic Council

Some questions are too big for one voice. The Cosmic Council puts four figures in a room around a single question and lets them disagree. A moderator holds the thread, three thinkers push back on each other, and you listen to ideas collide the way they never could in their own lifetimes. There are 110 crafted debates ready to play, each with full narrated audio. Or build your own. Choose the moderator, choose the three voices, choose the question, and convene a conversation that has never happened before.

The Calling That Won't Shut Up

Four AI Echoes, one of them moderating. Interpretations, not recordings.

Honest, by design

Honest

We are upfront about what this is. Every figure is an AI Echo, an interpretation grounded in primary works and historical context. Never a recording, never claimed to speak for the real person. Each figure ships with factchecks that name what is verified and what is recreated for the story.

Yours

Your conversations stay in your browser, and we never store them on our servers. Bring your own OpenRouter key if you like, and it never touches our servers. No tracking cookies, no third-party analytics, no profiles of who you are. What is yours stays yours.

Open

Live speech runs on our own GPUs in Germany, the rest of the audio on EU hosting, and the whole codebase is open under AGPL-3.0. You can also run it entirely on your own machine. Local Mode points the app at any OpenAI-compatible LLM, like LM Studio, Ollama, or vLLM, and runs the audio stack in docker, so no conversation, voice, or text data ever leaves your computer. So you don't have to trust us. You can check.

Questions people ask

What is Agora Cosmica?
An education platform built as a living library you can talk to. Thirty figures from the past teach you through narrated life stories, core teachings, and four-voice debates, and you can talk an idea through with them too, from Marcus Aurelius to Frida Kahlo, in English and German. Nonprofit, open source, and built to be checked.
So it is an AI chatbot?
Not really. Most of what you learn here is crafted ahead of time, 360 narrated stories, 360 core teachings, 360 prism dialogues, and 110 council debates. Live AI conversation is one of the ways to learn, for talking an idea through or asking anything, not the whole thing.
Is this really the historical person speaking?
No. Every figure is an AI Echo, a voice shaped by their own writing and ideas. It draws on their real philosophy, and it stays an interpretation. Never a recording, never the actual person.
Isn't it disrespectful to put words in the mouths of real people who can't consent?

We think the instinct behind this question is healthy. We ask it ourselves. But speaking for the dead is also one of humanity's oldest learning practices: Socrates wrote nothing, and most of what we “know” he said is Plato speaking in his voice. The tradition's verdict was never that portraying the dead is wrong. What was wrong was doing it without telling. So we tell: every figure is an AI Echo, never the person. Every figure ships with a factcheck separating verified from recreated, shadows included. And the whole app is built to be outgrown, a doorway toward the primary texts. If you still think we've gotten it wrong, write to us.

Read the longer answer

Three facts anchor our thinking.

First, the oldest voices of philosophy reach us through other hands. Socrates wrote nothing. Plato gave him thirty dialogues' worth of words. Xenophon's Socrates differs from Plato's, and contemporaries plainly read these texts as portrayals, not transcripts. The Stoics went further and made imagined consultation a deliberate exercise: Seneca advised choosing “a Cato”, a dead exemplar to consult in the mind, to imagine watching you. The practice reaches into our own library: Plato made conversation with his dead teacher the form of his life's work, Marcus Aurelius noted the same precept in his private journal, and Jung turned dialogue with inner figures, the dead among them, into a method he taught.

Second, it was the pedagogy. For roughly two thousand years, students of rhetoric learned by composing speeches in the voice of historical figures. Ancient teachers even had a dedicated name for voicing the dead: eidolopoeia. Dante built the Divine Comedy around a dead poet serving as his tutor. Fénelon wrote dialogues of the dead expressly to educate the Duke of Burgundy, Louis XIV's grandson, then second in line to the French throne.

Third, even rigorous history does it, with disclosure. Thucydides, the father of critical history, stated openly that he composed the speeches in his work himself, staying as close as he could to the sense of what was actually said. That sentence does the work a factcheck sheet does today.

And here is where the analogy honestly breaks: a book's Socrates speaks fixed words an author vetted and signed. An AI generates live answers nobody reviewed, in an immersive first-person voice. The risk is real. “Amadeus” revived a slander already a century and a half old and fixed it to the real Salieri's name for two more generations. That is exactly why our disclosure isn't decoration: our published instruction files are our signature, the factchecks are our method note, and the Echo framing never leaves the room.

Who are the 30 figures?
Philosophers, scientists, mystics, artists, and activists across 2,500 years. Laozi, Plato, Rumi, Hildegard von Bingen, Galileo Galilei, Albert Einstein, Frida Kahlo, Virginia Woolf, Harriet Tubman, Carl Gustav Jung, and twenty more. Browse all 30 on the figures page.
How do I learn from a figure?
Six ways. Hear a Story from their life. Work through a Wisdom conversation on one of their core teachings. Listen to a four-voice Prism dialogue. Take a short Quest challenge. Ask anything in Free Talk. Or gather a Cosmic Council of four figures to debate one question. The first four form a learning arc.
What is the Cosmic Council?
Four figures around one question, with a moderator holding the thread. There are 110 crafted debates with narrated audio. Or build your own, choosing the lineup and the question yourself.
How do you handle my privacy?
Your conversations stay in your browser and we never store them on our servers. No tracking cookies, no third-party analytics, no profiles of you. If you bring your own key, it never touches our servers.
Where does the audio come from?
Live text-to-speech and speech-to-text run on our own GPU servers in Germany. The narrated stories and debates are stored on EU hosting and served worldwide.
Is it open source?
Yes. The code is open under AGPL-3.0, so anyone can read it, audit the privacy claims, contribute, or run their own copy. The content moves to a CC-BY license within 6 to 12 months.
Is the content accurate?
Each voice is grounded in primary works and cross-checked sources. Because the Echoes are AI-rendered, what they say will vary, but the source material does not. Where the prose goes beyond the documented record, the factcheck names what was recreated.
Is it available in German?
Yes. Everything is fully bilingual, English and German, across the content, the interface, and the audio.

Built for learning, open to everyone

Agora Cosmica is a project of ChipMates gemeinnützige GmbH, a small German nonprofit in Freiburg. Charitable status means we answer to a mission, not to investors. No profits, no shareholders, just the work. The way you learn from each figure follows a four-step arc. Receive an idea, explore it, connect it, then prove you have it. No prerequisites, no paywalls. Schools and universities are welcome to bring it to their students, and developers can read every line or self-host the whole platform with one command. We count it a success the day you outgrow us, moving from our introductions to the primary texts, from AI conversations to human teachers, from curiosity to committed study. We are early, and we will get things wrong. When we do, tell us at [email protected]. We are not building this for you. We are building it with you.
