the plain works
software for people who build things
The Plain Works Co., Ltd. builds and runs business software that drafts, edits and checks documents. Every answer links to the passage it came from, and every edit is shown as a tracked change before anyone relies on it.
Security
Customer data is stored in the United States, encrypted in transit, and encrypted at rest by our infrastructure providers. Customer content is not used to train AI models, by us or by our AI providers under their API terms. Every service that processes customer data is listed by name.
Vendor reviews
We complete security questionnaires and send data processing terms and company registration documents on request. Write to hello@theplain.works with “Security review” in the subject.
