About "Prompt Lab"
Prompt Lab is no longer available
Prompt Lab was a Japan-made platform for designing and sharing prompts for generative AI, provided by Walkers, Inc. — but it is no longer available. As of this update, its official domain (prompt-laboratory.com) does not resolve via DNS and cannot be reached. We could not find an official shutdown notice, but the domain appears to have lapsed (as of August 2026).
This page summarizes information about the former Prompt Lab and currently available alternatives. The "What it offered" section below describes the service as it was and is no longer usable.
Alternatives
If you want to manage and share prompts, Promptitude.io is a close option. If you simply want to try prompts, you can use generative AI such as ChatGPT or Claude directly.
What it offered
Prompt Lab let you pick prompt templates organized by use case and create instructions for generative AI just by filling in the needed details. It supported saving, sharing and posting prompts, plus version management and team feedback, and its basic plan was offered for free.
The information on this page is current as of August 2026. We will update it if the service's status changes.
