Spell is a web-based "AI agents + plugins" productivity tool that lets users delegate tasks (research, writing, audits, data gathering, etc.) to autonomous or semi-autonomous agents. The product emphasizes:
- Autonomous agents that can execute multi-step tasks
- Parallel task execution (run multiple jobs at once)
- A template/prompt library and prompt variables for repeatable workflows
- A plugin catalog (web browsing/search, scraping, file access, etc.)
In practice, Spell functions as a no/low-code wrapper around LLM-powered task execution—positioned as an agentic task runner rather than a pure chat interface.
