Key Features and Functions include:

Automated Time Capture
Apollo automatically records and analyzes digital activity—including emails, documents, and other work signals—to identify potentially billable tasks. The system helps reduce missed time entries and supports more accurate contemporaneous timekeeping.

AI-Generated Narratives
The platform generates draft billing narratives using artificial intelligence based on captured work activity. These narrative suggestions can be reviewed and edited by the user prior to submission, helping reduce the administrative effort associated with manual time entry.

Predictive Client and Matter Assignment
Apollo uses activity metadata and historical work patterns to suggest the most likely client and matter for each captured activity. This predictive matching helps streamline the process of categorizing work for billing purposes.

Reconstruction of Billable Work
For users who enter time retrospectively, Apollo provides tools to reconstruct billable activity by analyzing past work signals. This enables users to review suggested entries and convert them into billable time more efficiently.

Real-Time Visibility into Time Capture
The system provides dashboards and reporting tools that allow firms and individual timekeepers to review captured activities and submitted time entries. This visibility can assist firms in identifying time leakage and improving time entry compliance.

Integration with Aderant’s AI Ecosystem (MADDI)
Apollo operates within Aderant’s broader AI-enabled work-to-cash platform. Through MADDI, Aderant’s AI-powered virtual associate, generative and agentic technologies support automated workflows, compliance checks, and contextual recommendations across billing and revenue operations.

This was formerly a solution from Hercules AI.  In August 2025, Aderant signed an agreement to purchase the legal tech assets of HerculesAI, including Apollo, Verify, and Athena. HerculesAI was fomerly known as ZERO.
