Otto Assistant vs. Otto PPC

September 30, 2025
Black Hills AI offers two powerful AI legal assistant tools - Otto Assistant and Otto Power Patent Center (PPC). These complementary tools can be implemented individually or combined to create a comprehensive AI-powered legal workflow solution.
Both Otto Assistant and Otto PPC are built on sophisticated legal and IP-specific training, including the understanding of complex patent terminology, legal concepts, and professional workflows. This specialized training ensures that both tools effectively assist legal and IP professionals with tasks ranging from patent prosecution to trademark work and general legal document preparation.

Security

Both Otto Assistant and Otto PPC have security measures in place that are critical to legal professionals. This includes both tools being closed off from the internet and zero-retention APIs through the entire process. This means we don't retain any of your information for training purposes. Simply put, your data remains your data.

Access & Setup

Both Otto Assistant and Otto PPC are web-based platforms.

Otto Assistant is accessed through a dedicated site, requiring a username and password to access the tool. Set-up only requires a name and email address.

Otto PPC is integrated directly into Black Hills AI's Portal and Word add-in. Full set-up will require sponsorship form the USPTO for us to scrape your documents, but the tool does not require sponsorship.

The username and password used to log into the Portal and Word add-in are the same used to access Otto Assistant, providing a seamless experience for users leveraging both tools.

Context Management

Both tools give the user total control over what information is in and out of context for the project they are working on.

Otto Assistant relies on manual document uploads from users. Multiple document types can be added to context, including Word, PDF, and TXT files. The tool understands and can help you analyze a wide range of legal documents, including office actions, applications, and contracts.

Otto PPC is tied directly to our automated scrape and verification of USPTO correspondence, providing users faster and more streamlined access to a matter's documents. Users still control what is added to Otto PPC's context, but with a simple click of a button rather than manual uploading. Users can also manually upload any documents as needed.

Pricing Model

Otto Assistant is priced per seat, with the option to set up an annual or monthly subscription. Subscriptions include full access to the tool with no additional fees.

Otto PPC is included in the monthly cost for our automated USPTO scrape and verification process, which is billed based on the number of pending US patent matters in your portfolio.

Tool Maintenance and Updates

Both Otto Assistant and Otto PPC are continually updated and maintained to provide users with the best experience possible.

Otto Assistant was developed in partnership with a third party, which manages the maintenance and updates of the tool.

Otto PPC was developed fully in-house by Black Hills AI, so we provide the ongoing maintenance and updates.
