A deterministic conversational engine. Every reply can be re-derived from the record it carries.
Your conversations are stored in your account so you can return to them. Deleting your account deletes them.

Ackren is not a language model. It parses what you say against a published grammar, keeps a visible ledger of what you have asserted, and answers from that ledger with attribution. It has no knowledge base yet, so it says so rather than guessing.
Small talk works best. Anything outside the published grammar fragment is flagged with a typed reason instead of being answered. It cannot look things up, summarise, translate, write, or reason about the world. It converses in English only, whatever language this interface is set to.
This hosted instance is display-only evidence. The determinism gates run locally against the pinned build, and this page may run on a different interpreter than the one those gates ran on.
Build
A conversation keeps the build it was started on. Edge conversations lose their resumable state whenever a new edge build is deployed; the transcript stays as a record.
Quoted echoes appear marked because they are your words coming back, not the engine's.
