We're a small Berlin group building open-source tools for the common good, funded by grants and donations, never investors. Everything below is open for volunteers.
DDAI
DDAI (Democratic Decentralised AI) is building an open AI layer that no single company or state can switch off. It focuses on edge devices: the phones, laptops and home computers people already own, joined together to run open AI models. The network is owned and governed by the people who use it and power it. Part of every fee goes into an AI Commons that guarantees everyone basic access to AI, with priority for the global south. It has four parts: Mycelium (shared computing), Mycorrhiza (payments, verification and identity), Spora (the apps people use) and the Model Detector (checks which model really answered).

Mycelium · part of DDAI
Mycelium lets several ordinary computers, such as a Mac and a laptop, share the work of running one large AI model that none of them could run alone. Each computer holds a slice of the model and passes its partial result to the next. The goal is a free, open-source tool that a household, lab or co-op can run on its own devices without sending anything to a big tech provider.

Mycorrhiza · part of DDAI
Mycorrhiza is the "rules and money" part of DDAI: how people who share their computers get paid, how we check the work was done honestly, how we tell real people from fake accounts without demanding passports, and what shared rules apply to everyone. The idea is a very small shared ledger (a blockchain) that only enforces the basics.

Spora · part of DDAI
Spora will be how people and other projects use DDAI: a shared layer that apps build on, our own default chat app for private, decentralised AI, and connections that let existing compute networks plug into DDAI. It is at the very start: nothing has been researched or planned yet.

Model Detector · part of DDAI
A tool that reads a conversation plus an AI answer and estimates whether the answer likely came from one specific big model (Qwen3.8-27B) or from a cheaper imitation. It gives a statistical likelihood, not proof, and it is meant as an early safeguard against providers quietly swapping in cheaper models.

Commons Atlas
Commons Atlas is a tool for researchers and reviewers. It maps who holds concentrated economic power in markets such as payments, housing, funerals and children's care. It then looks for places where a shared, community-run alternative could help instead. Every claim has to point to a quoted source passage. Software drafts and checks the research, but humans make every decision, such as which areas to study, which to pursue, and whether to publish or spend money.

Spark
Spark searches the world for public policies that measurably improved people's lives and also gave more control to the people affected, such as participatory budgets or community land titles. For each strong policy it builds a fully cited "evidence bundle". It then finds places that could adopt the policy and drafts tailored briefings. Nothing is published or sent until a human approves it.

Phonemesh
Phonemesh lets people message each other over cheap long-range radios (Meshtastic/LoRa) in places where internet is unreliable, expensive or missing. You can send text, voice-style messages and small pictures. For voice, your phone turns speech into text, the text travels over the radio, and the other phone reads it out loud, which is what lets it fit through such a tiny, slow link. A small village hub can pass messages on.

dmaps
dmaps is a Germany-focused version of the free, privacy-respecting CoMaps map app. The first slice adds train and bus departure boards that work without internet for Berlin/Brandenburg, with an optional live-delay layer that is off by default. The long-term idea is a Germany-first map app that is a real alternative to Google/Apple Maps without tracking.

Embervoice
Embervoice turns an ebook into an audiobook on your own Mac. You pick a narrator style, listen to a short sample, then make the whole book. Everything runs on the computer, so your books and recordings are never sent to a cloud service.

Brokerbane
Companies called data brokers collect and sell personal details. Brokerbane helps a person send formal deletion requests (under European and Californian privacy laws) to over a thousand of them and tracks the replies. It runs on your own computer, and your details stay encrypted there.

desocial (working title)
An Android app (plus a browser preview) that puts your photo-sharing accounts in one place. Today it combines Pixelfed (an open, decentralised Instagram-like network) and Instagram, so you can swipe between them, keep drafts, and back up your own data, instead of juggling separate apps. It is a working prototype for the owner's own testing, not something volunteers or the public can use yet.
