Our verdict on Sandbox
Sandbox brings legal research and firm-document workflows into a cloud-based assistant aimed at small and mid-sized firms, with an initial focus on immigration lawyers. It can search categorized legal libraries and provide responses with citations and links to verified sources. For work on a firm’s own material, users can upload documents, ask questions across personal or shared libraries, and generate summaries at three complexity levels. PrivateGPT chat is connected to GPT-4, while saved prompt templates, user management, and permissions support shared team use. The emphasis is on research and working with firm knowledge rather than a broad general-purpose assistant.
The published plans show Premium at $150 per user per month with annual billing and a 14-day trial. Premium includes Document Q&A, PrivateGPT, summarization, unlimited data storage, and 24/5 email and chat support. Enterprise includes Premium features plus Custom Drafts, white-labeling, and custom onboarding; its price is available through sales. That makes Premium’s entry cost relatively clear, while teams considering branding or custom onboarding need to discuss Enterprise directly. The listed platform is web, and deployment is cloud.
For small teams that need cited legal research alongside Q&A over their own files, the combination of source links, searchable libraries, summaries, and permissions is a practical fit. The feature set also includes prompt sharing and document drafting support, with custom drafts specifically noted for Enterprise. Compliance information identifies GDPR and two-factor authentication; the vendor says it is pursuing SOC 2 Type II certification, not that certification is complete. Teams that need 24/7 support, another platform, or a wider assistant feature set should compare alternatives. Larger firms evaluating white-label customization may find Enterprise relevant, but should first clarify its pricing and requirements with the vendor.
