Blackletter is built on two pillars:
Human, client‑lawyer relationships
and
proprietary technology.
We operate a custom legal harness and an AI agent built on it.
Both are designed to enhance and accelerate legal work, at scale.

The platform keeps a comprehensive record of clients’ business context, preferred positions, and earlier decisions, along with explanations for those decisions. Each engagement builds on the last, so the workflow retains continuity, and clients never have to explain themselves.

The agent works through multi-step assignments: reading documents, gathering relevant information, drafting, revising, and checking its own work. It runs on our infrastructure, not a lawyer’s laptop, so work continues after they log off.

The agent tracks changes directly in agreements, preserves existing markups, and checks the resulting edits. Lawyers then review and refine the work in the same platform. The result is faster turnaround and cleaner, more focused redlines.

Each matter has a single workspace that holds all relevant documents, instructions, history, and more. The lawyers assigned to the matter work there alongside the agent. They follow progress, add context, and steer the work, always with a clear record of every step.

Our harness works across multiple LLMs. We test models continuously against real legal tasks so we can match each task to the best-fit model, and adopt new models as they improve. Client context and history live in Blackletter’s platform, so we preserve continuity even as we swap models.

Our platform is built around rigorous confidentiality. Access to client information is limited to the lawyers working on each matter, and every action in the workspace is logged. Our model providers operate under enterprise terms that prohibit training on client data and limit how long it’s retained. All data is encrypted.

Clients work closely with their lawyers; substantive, sensitive or complex conversations happen person to person. The phone is part of our tech stack: Clients can call their lawyer whenever they need to (and fixed pricing means they never see a bill for it). Our lawyers bring expert judgment and deep strategic thinking to every matter, reviewing and approving every document before it leaves the firm.
