How to Develop an AI Assistant like CoCounsel: Insights for Legal, Tax, Audit and Accounting Professionals

A missed clause in a contract, an overlooked compliance update, or hours lost reviewing filings can directly impact business outcomes. Legal, tax, audit, and accounting teams work in environments where accuracy matters as much as speed. This pressure is exactly why organizations are moving toward intelligent assistants built specifically for professional workflows rather than general-purpose tools.

Market signals clearly reflect this shift. The legal AI assistant market is projected to reach USD 18 billion by 2035, showing how rapidly professional services are adopting AI-driven systems.

Instead of replacing expertise, modern assistants extend it. They help professionals review information faster, surface risks earlier, and support decision-making without disrupting existing processes.

Key forces driving adoption include:

• Rising regulatory complexity across legal and financial operations
• Increasing document volumes across contracts, audits, and tax filings
• Demand for faster turnaround without expanding team size
• Growing reliance on generative AI to analyze structured and unstructured documents
• Enterprise adoption of AI automation to reduce repetitive knowledge work

As firms evaluate how to develop an AI assistant like CoCounsel for legal work, the focus is shifting toward domain-trained systems that understand professional context. An enterprise AI Assistant today acts less like a chatbot and more like a digital analyst embedded into daily workflows.

This guide explains how organizations can develop AI legal assistants like CoCounsel while meeting the expectations of regulated professional environments.

What is CoCounsel and How Does it Work?

Legal and professional teams rely on careful analysis, structured research, and precise documentation every day. Understanding how CoCounsel operates helps organizations see how intelligent assistants can support real workflows instead of adding another standalone tool.

What Is CoCounsel?

CoCounsel is an AI-powered professional assistant designed to support legal work by helping teams review documents, conduct research, and analyze information faster. It works as a task-focused system that assists professionals during real assignments rather than casual conversations.

Organizations planning to develop an AI assistant like CoCounsel for legal work often focus on building structured assistance that fits naturally into daily professional workflows. The assistant becomes useful because it understands work context and delivers outputs aligned with professional expectations.

How Does CoCounsel Work?

• Task-Based Interaction: Users assign specific professional tasks such as reviewing contracts or summarizing case materials. The assistant interprets the objective and follows structured reasoning steps to generate organized and usable outputs.
• Document Processing and Understanding: The system reads uploaded files, breaks content into logical sections, and identifies relevant information. This allows professionals to work with large document sets without manually reviewing every page.
• Context-Aware Legal Research: The system analyzes trusted knowledge sources and presents findings aligned with the user’s query while maintaining relevance to ongoing work context.
• Workflow Alignment Through AI Integration: Instead of operating separately, the assistant connects with internal tools and databases. Thoughtful AI integration ensures research, drafting, and review tasks happen within familiar professional environments.
• Evidence-Linked Responses: Outputs include references tied to analyzed materials, helping professionals validate conclusions quickly. This builds trust and supports responsible adoption across regulated legal and compliance workflows.
• Continuous Workflow Improvement: Organizations integrate AI gradually, allowing the assistant to adapt to usage patterns while maintaining strict data boundaries and consistent operational logic suited for professional service environments.

A well-designed assistant succeeds because it supports how professionals already work. Teams investing in AI assistant development like CoCounsel for legal professionals aim to enhance productivity while preserving accuracy, accountability, and professional judgment.
