Project context, issues, memory and hours — from the first message.
An orchestration system for a team of role-specialized AI workers — developer, QA, PM — that run on your machine (via the arc CLI), share persistent project memory, and ship from an issue tracker. Works with your Claude subscription or Anthropic API key.
You lose 2 hours a day re-explaining the same project to different AI tools.
Your PM context lives in 4 Slack channels. Onboarding a junior takes three weeks.
You switch clients and lose stack context. Every project starts from scratch.
Worker roles for every function — developer, designer, QA, PM, copywriter, and more. Each with dedicated skills and project context. Assign tasks per role or let workers coordinate.
Issues, wiki, knowledge graph, and semantic search — all linked and always on. Self-hosted Cohere multilingual embeddings. No context loss between sessions.
Build knowledge collections from PDFs, video, YouTube, web pages, audio, DOCX, TXT, and images. Attach collections to issues. Workers see them when picking up tasks.
Telegram supergroup with a topic per worker. Or web. Or CLI. Switch any time. Project memory stays the same across all three.
Your code stays in your own repository. Arc keeps issues, history and hours on servers in the EU. Bring your Claude subscription or Anthropic API key — we never resell tokens.
arc <project> opens a worker session with full context loaded. Web companion handles visualization. Telegram handles async review. All three stay in sync.
Connect a GitHub repo or start from scratch. Workers bootstrap in 30 seconds. Your project gets isolated memory, a wiki, and an issue tracker — ready on day one.
Choose worker roles and load skills from 140+ options. Or fork a community template. Each worker carries the right context for its job — no manual briefing required.
Assign issues from CLI, web, or Telegram. Workers pick up the task, ship output, and ping you when done. You review and approve. Repeat.
Pain: Five AI chat tabs open. Context fragmented. Copy-paste is your daily workflow.
Outcome: "An AI dev team that knows my codebase. Opens a session, picks up where I left off, ships a PR."
Pain: Onboarding a new junior burns weeks. PM context is scattered across four Slack channels.
Outcome: "Each project has its own AI team with shared memory. Juniors ramp up by reading worker logs, not asking questions."
Pain: Client switching kills focus. Every project needs different stack knowledge from scratch.
Outcome: "Per-client AI team with isolated memory and skills. We handle 30% more work without adding headcount."
Yes. Arc OS is built around Anthropic Claude. We don't resell AI tokens — you bring your own. Claude Pro / Max / Teams — log in with OAuth. Anthropic API key (BYOK) — paste your key, we pass requests through with no markup. Arc OS charges for the orchestration layer — Claude is yours.
Cursor and Claude Code are single AI assistants. Arc OS is a team — multiple role-specialized workers with shared project memory that persists between sessions. Notes (knowledge collections from PDFs, video, YouTube, and web) attach to issues. When a worker picks up a task, it reads the attached notes.
Chat history and API keys are encrypted at rest on our servers (AES-256-GCM, server-held key). To run your workers, our servers process messages in plaintext and send them to Anthropic (Claude). 2FA on all plans; GDPR Art.17 delete and Art.20 export. Servers in the EU.
Today: one owner per project. Project Collaboration — multi-user, invite by email, roles, shared worker memory — is in active development.
Not yet. Cloud only today, with data stored in the EU. A self-hosted edition is on the roadmap — earliest 2027.
Cowork is a personal assistant in Anthropic's cloud. Arc OS is an office for an AI team on a real server: named role-specialized workers, an issue tracker as the source of truth, an audit trail for every action — and hands in your infrastructure (repos, Docker, deploys). We don't compete with Claude — we build the home it works in.
You bring your own Claude subscription or API key with no markup, and Arc OS adds $0 (Free) or $4.99 (Starter) per month. We don't resell tokens, so we never profit from you burning more of them.
