Custom Agent BuilderComing Soon

Build your own AI agents. Governed by our infrastructure.

Define custom instructions. Connect your firm's data. Configure verification rules and compliance policies. Every custom agent runs through the same Verify, Comply, Prove pipeline as our built-in agents — your logic, our governance.

How It Works

You define the agent. We govern every output.

Custom agents run on the same governance infrastructure as every LegalAI Space agent. Your COLP sees custom agent activity on the same dashboard. The audit trail is the same. The compliance checking is the same. Custom means flexible — not ungoverned.

You Build

Define your agent

Instructions, data sources, rules, tools, and output format — all configured through a no-code builder.

Agent Executes

Your agent performs the task

Using your instructions, your data, and your rules — executing the workflow you designed.

We Verify

Independent verification

Every output is checked against the databases and thresholds you configured — plus our default legal verification.

We Check Compliance

Your policies + regulatory rules

Your firm's custom compliance policies are checked alongside SRA rules and EU AI Act requirements.

We Prove

Full audit trail generated

Immutable record of what the agent did, what was verified, what compliance checks ran, and the results.

Building Blocks

Six building blocks. Infinite configurations.

Every custom agent is assembled from these components. No code required — configure through a visual builder and test against sample inputs before deploying.

Custom Instructions

Define exactly what your agent does. Set its persona, reasoning approach, output format, and domain boundaries. Write instructions in plain English — no code required.

Analyse lease agreements using our commercial real estate playbook
Research regulatory guidance from FCA, SRA, and ICO for financial services clients
Draft client update letters in our house style with matter-specific context

Your Firm's Data

Connect the knowledge your agent needs. Precedent libraries, internal playbooks, know-how articles, client-specific instructions, template banks — your agent works from your firm's expertise, not generic training data.

Firm precedent library and clause bank
Practice-area-specific know-how articles and guidance notes
Client-specific instructions, engagement terms, and standing orders

Verification Rules

Configure how outputs are verified. Choose which databases to check against, set confidence thresholds, define what counts as a pass or fail, and specify how edge cases are escalated.

Verify all case citations against BAILII with a 95% confidence threshold
Check statutory references against legislation.gov.uk including amendment status
Escalate to human review if verification confidence drops below 80%

Compliance Policies

Encode your firm's own rules as policy-as-code — on top of the SRA and EU AI Act rules already built in. Practice-area requirements, client-specific obligations, information barriers, and risk thresholds.

Apply financial services confidentiality rules for banking clients
Enforce information barriers between the M&A and litigation teams
Flag any output mentioning client names for manual review

Tools and Integrations

Connect your agent to external systems. APIs, internal databases, document management systems, case management platforms, and third-party legal databases — your agent can read from and write to the systems your firm already uses.

Pull matter context from iManage or NetDocuments
Search your firm's CRM for client relationship history
Query commercial databases (Westlaw UK, LexisNexis) via API

Output Configuration

Control what your agent produces and how. Define output templates, formatting standards, metadata requirements, and delivery rules. Every output matches your firm's quality expectations.

Generate structured research memos in our standard format with risk ratings
Produce comparison tables with source citations for every data point
Deliver outputs with a governance summary suitable for client forwarding
Use Cases

What firms are building

These are examples of custom agents firms have described during our research conversations. Each would take minutes to configure — and every output would be governed automatically.

Regulatory Change Tracker

A custom agent that monitors specific regulatory bodies relevant to your practice areas, assesses impact against your client portfolio, and generates practice-area-specific briefing notes in your firm's format.

RegulatoryMonitoringBriefings

Panel Tender Assistant

An agent configured with your firm's credentials, experience database, and tender response templates that drafts first-response answers to RFP questions using your actual track record.

Business DevelopmentTendersDrafting

Sector-Specific Research Agent

A research agent pre-configured with your firm's sector expertise — financial services, healthcare, technology, energy — that understands sector-specific regulatory frameworks and client terminology.

ComplianceInternal PoliciesQuality Control

Precedent Analyst

Knowledge ManagementPrecedentsDrafting

Custom doesn't mean ungoverned

Every custom agent — regardless of its instructions, data sources, or configuration — runs through the same Verify, Comply, Prove governance pipeline. Your COLP dashboard shows custom agent activity alongside built-in agents. Audit trails are generated automatically. Compliance is checked continuously. The governance is the infrastructure, not the agent.

Same verification

Citations checked against authoritative databases, plus your custom verification rules

Same compliance

SRA rules + EU AI Act + your firm's custom policies — all evaluated automatically

Same audit trail

Immutable, cryptographically verified record of every action and decision

Important notices
  • LegalAI Space is a technology platform. We are not a law firm and do not provide legal advice. Custom agents assist with legal work but do not replace qualified legal counsel or professional judgement.
  • Custom Agent Builder capabilities described on this page represent planned functionality. Final capabilities, configuration options, and availability may vary.
  • Custom compliance policies configured by firms supplement — but do not replace — the platform's built-in regulatory compliance checking (SRA, EU AI Act). Firms are responsible for the accuracy and appropriateness of their custom rules.
