Stronghold is an estate-planning and family organisation service designed to help people manage important documents and information in one accessible place. Its platform lets users organise records related to wills, powers of attorney, property, life insurance, pensions, and other key matters, alongside assets, contacts, and essential details. Users can add information by taking photos or uploading files, and Stronghold’s AI can suggest records to create and summarise documents for their files.

The AI also provides guidance on using the service and getting organised. Stronghold supports collaboration by allowing users to invite a spouse or trusted adviser, or share files through secure links. The company says its AI cannot access users’ files and that data is protected with multi-layered encryption and two-factor authentication.

Stronghold offers free sign-up and a paid Premium plan; its website advertises a limited-time discount. It also provides a help centre, FAQs, blog articles, and resources on estate planning and organising family information. Stronghold is operated by Stronghold Systems Limited, based in London
