crystl

crystl is a Metal-accelerated macOS terminal designed for multitasking with AI agents. It organizes projects into gems, treats terminal sessions as shards, and uses floating panels to handle approvals and notifications. The tool supports running multiple agents on the same repository with separate git worktrees, and it preserves conversations and context across sessions for later reference. It functions as a normal terminal while exposing AI-oriented features when needed.

In crystl, each project becomes a gem, and every session inside it is a shard. The interface displays approvals, questions, and status updates via floating glass cards. Agent sessions autosave and restore, and an orchestrator can manage subagents or launch group quests. The setup emphasizes visibility and control, keeping complex multi-agent work manageable within one app.

The system surfaces live agent activity through a dedicated panel and a crystal rail that shows all gems and their shards. It supports token tracking, per-project task workbenches, and a project optimizer to identify setup gaps. Remote development over SSH and GPU-accelerated rendering are included, and the platform integrates an API key storage mechanism, a markdown editor, and a command-line interface for automation.

The product offers plans with a free tier and a paid Guild tier, with explicit mentions of open models, iPhone access, and multi-device support. It notes macOS-only availability and emphasizes features like orchestration, quest parties, and open-model support while describing how each plan differs in capabilities and limits.

Use cases
