Anthropic Rebuilds Claude Projects: One Conversation Orchestrating Parallel Cloud Threads

On September 18, Anthropic announced a major rebuild of Claude Projects, launching as a beta in Claude Code on desktop and web, rolling out gradually to select Pro/Max users with a waitlist. The core change: projects evolve from "folders" into "an ongoing conversation" — users drop tasks in any order into a single session, and Claude automatically decomposes them, spins up parallel threads, coordinates the work, and aggregates results.

Confirmed

• Each thread is a cloud-hosted Claude Code session that keeps running after the local machine goes offline; users can jump in from their phone. Official threads note local files, tools, and intranet access are "coming soon" — not yet available.
• Users can assign multiple tasks like briefing a chief of staff; Claude routes them to new or existing threads and proactively asks for decisions, with an Overview panel collecting pending decision points.
• Projects have shared memory: each thread reads and writes to it (e.g., "the launch moved to Friday", "ask before touching billing"), and a project library stores uploaded and generated content. Per official docs, each project is managed by one agent that spawns subagents for tasks.
• The official blog shows Claude splitting parallel tasks, opening PRs, coordinating across repos, and reviewing thread outputs.
• Anthropic's lydiahallie said the rollout is staged; users can DM their email for early access, and migration for existing Projects is still in progress.
• Engineer pranathiperii (relayed by maxleiter) called it months of team work, having "used Projects to develop Projects".
• Anthropic CTO and Instagram co-founder Mike Krieger publicly praised it, saying running multiple coordinated background tasks is already his primary way of using Claude.

Why it matters

• This shifts AI from "one conversation, one task" to orchestration of parallel threads, drastically cutting the cost of managing multiple sessions; Daniel Mac linked it to his Latent Space vision of "one interface for all work".
• Cloud execution plus mobile access removes the constraint that long tasks depend on a local machine being online.
• Shared memory keeps context consistent across threads — a key step toward long-term, collaborative AI engineering agents.
• The CTO's public endorsement signals real, high-frequency internal validation rather than a concept launch.
