Who is behind Agora Cosmica?
A Living Library You Can Talk To
Agora Cosmica is built by ChipMates gemeinnützige GmbH, a small German nonprofit in Freiburg. It is a place where you can talk with 30 people from history, from Marcus Aurelius to Frida Kahlo. We built it because good ideas sit behind paywalls, reading lists, and university walls. They should not. The code is open and the sources are public.
The organization
ChipMates started as a GmbH in 2023. In 2025 it was granted gemeinnützige status, the German term for a registered charity. It sits in the commercial register at Amtsgericht Freiburg under HRB 728848. The purpose on record is the advancement of education.
Nonprofit means we answer to that purpose and not to investors. No shareholders, no profit to hand out, just the work. Agora Cosmica is open to anyone, anywhere, and the code is open source under AGPL-3.0.
What we hold to
- Gratitude
- Every era and tradition has something to teach us.

- Openness
- Nonprofit. Open source. Built for the community.
- Transformation
- Inner growth ripples outward.
Why it exists
The ideas that help people most are often the hardest to reach. They sit in books nobody hands you, in courses that cost money, in sentences written for other scholars. We think that is the wrong way round. So we took 30 people from philosophy, science, faith, art, and activism, and made their thinking something you can talk through in your own words.
We count it a success the day you outgrow us. From our short introductions to the real books. From talking with an AI to sitting with a human teacher. From curiosity to study of your own. That is the whole point.

What you can do here
30 remarkable people from history, each with their own voice. From Marcus Aurelius to Frida Kahlo, from Rumi to Virginia Woolf. When they speak, they draw on their actual philosophy, their real-life experiences, and the ideas they spent their lives developing.
Every voice is built from primary works, historical context, and sources we cross-check. The Echoes are AI, so the exact words change each time you ask. The source material does not. Where the story goes past the documented record, the factcheck says so.
360 narrated story chapters, 360 core teachings, 360 multi-perspective prism dialogues, 110 crafted council debates, a complete audio library, and custom councils where you choose the participants. With 30 free messages a day to get started.
Every person here comes with six ways in. Pick the one that fits your evening.

Voice technology
German voice synthesis uses Qwen3-TTS as the primary engine, with F5-TTS by SWivid et al. (MIT code) as the overflow tier. The F5-TTS German fine-tuning is by hvoss-techfak (CC-BY-NC-4.0), trained on Mozilla Common Voice 19.0 (CC-BY-4.0) and the Emilia dataset. English voice synthesis uses Kokoro by hexgrad. Live transcription uses faster-whisper, a CTranslate2 port of OpenAI's Whisper, served via Speaches.
