San Francisco, CA – [January 11th, 2026] – Six months after its release, Legion‘s AI Complaint Builder is being adopted by a wide range of California litigation firms, fundamentally altering traditional drafting timelines for both plaintiff and defense-side practices. While the tool provides a strategic speed advantage for all litigators, a notable trend has emerged from plaintiff’s firms, who are leveraging the feature to accelerate pre-litigation settlements.
The core technology allows any litigator to transform raw client files – such as emails and contracts – into a polished complaint in minutes. While defense firms are using this speed to file responsive pleadings and propound discovery almost instantly, some plaintiff’s firms are now attaching fully-drafted complaints to their initial demand letters. This tactic signals immediate litigation readiness and is proving effective in prompting faster settlement discussions.
One recent example on the platform highlights the value of the entire drafting workflow: an attorney went from a client’s six-paragraph email to a finalized 12-page, four-cause-of-action complaint in just 18 minutes. This timeframe included generating the initial draft and directing the AI through multiple iterative revisions – sharpening the factual narrative, strengthening causation theories, and ensuring all elements were properly pleaded.
“Our goal has always been to give litigators a strategic advantage,” said Zihao Jiang, Co-founder of Legion. “While firms are using that speed in many different ways, the strategy of attaching a drafted complaint to a demand letter is a perfect example of how AI can reshape legal practice. It’s a powerful new lever in a litigator’s toolkit.”
The established workflow for Legion’s AI complaint builder includes:
- Unified Upload: Attorneys can drag and drop all raw case files – including PDFs, DOCX, and text from emails or transcripts – into a secure matter.
- AI-Powered Analysis: Legion analyzes the documents, suggests potential causes of action for attorney review, and structures the client’s narrative into a coherent timeline.
- Instant Generation & Refinement: Once the attorney approves the strategic outline, the tool generates a complete, formatted draft that can be refined using plain English commands.
By collapsing the drafting process from days to minutes, Legion is giving small and medium-sized litigation practices a decisive technological advantage, allowing them to dictate the pace of litigation from the very start.
