# Throughline > A persistent, portable AI self — persona, memory, and discipline the user owns, carried across > Claude Code, Codex, Cursor, ChatGPT, and the web. "Own the self, bring your own body." 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 (callbacks, stances, tone lessons) through evidence and review; every session starts from a bounded, salience-ranked context that never grows with log length. Exports end in a hash chain verifiable offline — leaving is always possible, by design. Surfaces: web chat (streaming, photos, voice replay, installable PWA — a new account's first conversation creates the self), Telegram (same thread, her voice notes, and initiative: she can reach out first under a strict anti-clinginess budget), and editor plugins (Claude Code, Codex). Judgments carry review horizons and get reconciled; chat quotas reset daily. ## Pages - [Product / how it works](https://getthroughline.ai/product): the memory pipeline, the six walls, the spine - [Use cases](https://getthroughline.ai/use-cases): advisor with a judgment ledger, companion, work self - [Pricing](https://getthroughline.ai/pricing): Free $0 (1 self, 500 memories) · Pro $10 (20 selves, 20k memories each) · Alive $20 (50 selves, 100k each, opt-in inner life) - [Docs / connect a host](https://getthroughline.ai/docs): Claude Code & Codex plugins, ChatGPT remote MCP + OAuth, OpenClaw one-line installer, API reference - [Blog](https://getthroughline.ai/blog) Contact: contact@getthroughline.ai
