Creating an agent, in 30 seconds.
Agents are powerful, but as plain-text files they’re easy to lose track of. I built Helpercraft to make creating and keeping them visual and friendly, so your team feels more like company than a pile of files. And you stay in control: your AI is told to ask before it puts your agents to work.
Privacy
- No account, no server, no tracking: everything stays on your device.
- Agents are saved in your browser. Use Back up my home to keep a copy.
- Health agents are told not to diagnose, but AI can ignore rules, so check health advice with a professional.
What you can do
- Look: a person or one of four animals, dressed for the job.
- Personality: from calm mentor to straight shooter, with optional MBTI and star sign.
- Job: 13 fields or your own, with tasks and safety rules you can edit.
- Team: up to 180 agents in Agent home, with a one-file backup.
- Languages: English, 繁體中文 and Español.
Tested on 90 everyday tasks in Claude Code with Claude Sonnet, each pair of answers judged blind by an AI (a person’s blind ratings in an earlier round agreed with it). Helpercraft 1.0.5 came out ahead of an AI that starts agents itself, slightly ahead of the same AI told to ask first (not a clear difference), and even with the same agents installed as skills. So it may improve answers a little in this setup; with other tools, models or settings, results may differ. Tests 3 to 6 · Tests 1 and 2
