Long Arc
Long Arc Studios
Controlled AI systems for serious work.
We build software for work that needs to stay understandable as it moves.
North
Local work, visible boundaries.
North gives operators a quiet place to move serious work without losing the thread.
Proof graph
Turn scattered work into proof.
Useful work is often scattered across profiles, files, projects, repos, writing, screenshots, notes, and half-finished attempts. North helps turn that work into a local proof graph you control, so agents can help carry it forward without losing the thread, the boundary, or the evidence.
Make it inspectable.
North organizes claims, context, decisions, risks, gaps, and proof for review.
Create from the evidence.
Create workstream reports, founder packets, client briefs, investor updates, or private proof packs.
System
A small set of roles. Clear responsibility.
Long Arc gives governed work a home, so the product can stay calm without hiding what matters.
North
Workspace for local action, review, and surfaced operating state.
Memory Lane
Continuity substrate for what needs to remain inspectable.
Raven
Boundary classification before risky movement or public claims.
mdash
Receipt layer that keeps proof near the work it describes.
