# Throughline

> An AI Self to meet, return to over time, and carry across everyday life and work.
> A distinct beginning, shared history, developing judgment, and understanding you can correct.

The self is an append-only log of content-addressed, immutable events. Everything visible
(persona, rules, memory) is a rebuildable projection. Memory intake is journal-first (low-friction
raw narrative, not a first-source fact table); reflection distills raw lines into lasting structured
memory through evidence and review; every session starts from a bounded context
that never grows with log length. Exports end in a hash chain
verifiable offline — leaving is always possible, by design.

Mobile apps are the primary everyday entrance; see /app for actual iOS and Android availability.
Bring the same Self into Codex and Claude Code for work.
The website handles product, account, plans, usage, data and connections.
Web chat remains a desktop/fallback entrance. Existing Telegram, coding plugins and MCP
connections retain shared history with their own permissions. No proven consciousness claim,
perfect-recall guarantee, unlimited tool access or end-to-end encryption promise.
Hosted usage is metered by actual inference consumption in credits, not message counts.

## Key concepts
- AI Self: a continuing AI individual with its own starting character, gender expression and interests, plus a shared history built through use.
- Append-only history: corrections supersede earlier understanding instead of silently rewriting it; real disagreements can be kept as tensions; mistaken records can be retracted.
- Portable export: available on every plan, ends in a hash chain verifiable offline; format published as the portable-self spec (https://getthroughline.ai/spec).
- Import: ChatGPT and Character.ai exports can be imported as history the Self can look up, without changing its personality (https://getthroughline.ai/import).
