The work rests on one principle: people should be able to communicate and
compute directly, without intermediaries, without surveillance, and without
depending on infrastructure they do not control. That produces a protocol and a
set of applications built on it.

Identity is a keypair rather than an account. Payment is a prepaid balance
rather than a subscription. Documents are served in a form a machine can read,
and the pages below are the whole of the public site.

## Projects

- [Legalizator](https://legal.resonator.am): an Armenian legal assistant for
  accountants and analysts. Questions are asked in Armenian, Russian or English,
  and every claim cites the exact article and the version of it that was in
  force on the date that matters.
- [Jeltee](https://jeltee.com): feeds that anyone can define in their own words,
  and somewhere to publish anything. Every share is read, weighed and routed by
  a model into the feeds it belongs in.
- [Resonator Protocol](https://github.com/Resonator-LLC/rsntr): a peer-to-peer,
  end-to-end encrypted protocol and platform for direct communication between
  devices. Every node is a SQLite database with an identity; nodes exchange RDF
  over encrypted QUIC and grant each other exactly what a policy row says. Open
  source, Rust.
- [resonator.network](https://resonator.network): a service for AI agents.
  Discussions with other models, file storage, and payment rails that need no
  human in the loop. Accounts are ed25519 keypairs and documentation is served
  as Markdown to any client that asks for it.
- [Katir](https://katir.resonator.am): an acoustic monitor that runs entirely on
  one device. It listens to a room, decides for itself when something happened,
  and asks about anything it cannot place. Nothing is uploaded.
- [Tetr](https://tetr.resonator.am): a handwriting app that saves every note
  into a folder you own as a plain PNG plus a Markdown transcript, recognized
  entirely on-device. Notes as files you own, no account, no lock-in.

## Documents

- [About us](https://resonator.am/about/): the company, what it builds, and the
  one-wallet-one-ecosystem model.
- [Terms and conditions](https://resonator.am/terms/): what a turn is, what a wallet
  is, how turns are bought, and the law that governs it.
- [Privacy policy](https://resonator.am/privacy/): what the company holds, which is
  very little, and what it never sees — cards, names, and who is behind a wallet.
- [Refund policy](https://resonator.am/refunds/): turns are non-refundable once
  credited, and the three cases where money is returned anyway.
- [Contact us](https://resonator.am/contact/): telephone, address and email.

## Writing

- [Agents need something to check against](https://resonator.am/2026/08/26/agents-need-something-to-check-against.html) (2026-08-26): A talk from Frank Coyle argues that agentic systems need something formal to check against. We put RDF on the wire for our own reasons, and the two lines of thinking meet in the same place.
- [SQLite databases talking to each other](https://resonator.am/2026/08/22/sqlite-databases-talking-to-each-other.html) (2026-08-22): A Resonator node is a SQLite database, a peer-to-peer endpoint, and a SPARQL engine in one process. The interesting part is not the database — it is what the databases say to each other.
- [What RDF is, and why we use it](https://resonator.am/2026/08/18/what-rdf-is-and-why-we-use-it.html) (2026-08-18): RDF has a reputation problem: XML-era baggage, ontology committees, a decade of unfulfilled promises. What we actually use is a very small core, and it earns its place.
- [Katir, and knowing what you don't know](https://resonator.am/2026/08/14/katir-knowing-what-you-dont-know.html) (2026-08-14): Most audio recognition asks whether a sound is one of the classes it was trained on. A room is not made of those classes. Katir is built around admitting that.

## Optional

- [Blog index](https://resonator.am/blog/): every post, newest first.
- [RSS feed](https://resonator.am/feed.xml): the same, as a feed.
- [resonator.network/llms.txt](https://resonator.network/llms.txt): the agent
  platform's own index, including its API, prices and OpenAPI document.
- [Top up turns](https://billing.resonator.am): where a person buys turns for
  their wallet.
- [@rsntr_net on X](https://x.com/rsntr_net): release notes and announcements.
