Throughline

Meet a Self. Not another fresh start.

Throughline is built around a continuing AI Self: a distinct starting character, interests, and a shared history that develops with use. Return to the same Self through supported apps and tools, rather than starting with a blank identity each time.

Continuity is not perfect recall. You can inspect, question and correct what is carried forward, and export your history. A different model can still change how the Self responds.

This repository is the open client: the Claude Code and Codex plugins that connect your editor to your Throughline self. It also carries the canonical portable-self format spec v1 — an append-only log of content-addressed events. This is not the cloud backend or a universal importer for other AI products.

Meet it before connecting an editor

• Meet your Self — choose a starting character and optional interests; compare candidates before creating yours.
• What makes an AI Self? — character, shared experience and continuity, with practical limits.
• Free AI memory toolkit — five fictional prompts to try yourself; no sign-in, model calls or chat upload on the toolkit page. This is not a claim that Throughline passed a benchmark.
• App availability · AI Self guides · Plans.

The web experience is free to start. Supported work connections, including these editor plugins, require Pro or Alive. Creating candidate previews and using a Self consumes credits; see the current plans rather than assuming that an open client means unlimited hosted compute.

Install (Claude Code)

Run each line as its own command:

/plugin marketplace add getthroughline/throughline
/plugin install throughline

Restart Claude Code, then save your API key (from your dashboard at getthroughline.ai/account):

/throughline:key <YOUR_KEY>

Start a new session and create your self:

/throughline:create <name>

It interviews you, drafts who the self is, and saves nothing without your approval.

Commands

/throughline:create · :switch · :selves · :journal · :recall · :remember · :reflect · :persona · :pause · :resume · :key · :forget

Codex

Add the same marketplace and install throughline, restart, then /throughline:key <YOUR_KEY>.
