Authority stays with you
Your record is not a feature locked inside the last model, provider, or interface you used.
AUGMENTED MEMORY INTERFACE
TheoSphere is a user-owned AMI memory appliance. It preserves source-linked history, corrections, chronology, and provenance, then supplies bounded context to replaceable AI consumers.
Not an AI. The intelligence can change. Your record stays yours.

AI tools are powerful, but their context usually starts anew: new window, new provider, new model, another reconstruction of what matters.
TheoSphere is designed as the continuity layer beneath that churn. It holds the accountable memory record while models remain useful, temporary consumers.
Your record is not a feature locked inside the last model, provider, or interface you used.
The important part is not only what was said. It is what changed, when it changed, and what source supports it.
TheoSphere is designed to supply bounded, source-linked context through standard interfaces. The consumer can change; your continuity does not have to.
The context tax is the repeated manual work of restating goals, decisions, corrections, relationships, and source history before an AI can be useful again.
TheoSphere aims to reduce that reconstruction by retrieving an evidence packet sized for the current task, instead of treating every prior word as disposable or every model as the owner of your history.
Here is the distinction between what has been demonstrated, what is in private development, and what still needs to be earned.
Demonstrated
A fresh, projectless Codex task received a bounded evidence packet through a real MCP prototype: source-linked context, exact provenance, and later correction or limitation boundaries. Codex remained the final speaker.
Private development beta
The current service is a versioned development snapshot that preserves recorded history, corrections, chronology, and provenance. It is not yet an encrypted production vault.
In development
TheoSphere is model-independent by design. Codex is the demonstrated consumer today; additional integrations, operational hardening, and governed capture are planned validation work.
FOUNDING ACCESS
TheoSphere is not taking payment, publishing a price, or promising a shipping date today. Founding access is a conversation about the continuity you need to preserve and the proof a real appliance should meet.
