Custom agent builderBuild Your Own

Build your own agent. We handle the governance.

Write the instructions. Connect your firm's data. Set the verification rules and the 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 as every other LegalAI Space agent. Same dashboard for your COLP, same audit trail, same compliance checks. 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

A tamper-proof, signed record of what the agent did, what was checked, which compliance checks ran, and the results.

Custom agents

Compose an agent from governed parts

Every custom agent is built from these pieces. No code — set it up in a visual builder and test it on sample inputs before you go live.

Custom Instructions

Say exactly what your agent does. Set its persona, how it reasons, the output format, and where its remit ends. Write it in plain English — no code.

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, playbooks, know-how, client instructions, template banks. It 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

Set your firm's own rules once and have them applied on every output — on top of the SRA and EU AI Act rules already built in. Practice-area requirements, client 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 and case management, third-party legal databases. It reads from and writes 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

Custom, not ungoverned

Custom doesn't mean ungoverned

Whatever its instructions, data, or setup, every custom agent runs through the same Verify, Comply, Prove pipeline. Your COLP dashboard shows it alongside the built-in agents. The governance comes from the platform, not the agent.

Same verification

Citations checked against authoritative databases, plus your custom verification rules

Same compliance

SRA rules, the EU AI Act, and your firm's own rules — all checked automatically

Same audit trail

A tamper-proof, signed record of every action and decision

Important notices
  1. 01

    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.

  2. 02

    Custom Agent Builder is available in early access. Configuration options and capabilities continue to evolve, and the exact feature set available to your firm may vary.

  3. 03

    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.
