Announcing GC AI's Legal AI API, Now Available
Cecilia Ziniti, Co-Founder and CEO•Published
GC AI's API is publicly available as of July 29, 2026. It is a REST API that lets your systems reach the same company-aware legal AI your team uses in the browser and in Word: chat, playbook reviews, files, projects, and company profile context. If you're weighing an internal build, see build vs. buy legal AI.
The next step is putting that intelligence into the apps and systems where the rest of the business works, without buying a seat for each person who needs an answer. Your playbooks and your governance still set the rules.
Connect legal AI to the tools you already use
GC AI's API connects GC AI directly to tools and automations: Salesforce, Ironclad, Jira, Zapier, Make, n8n, custom apps. Use it when a system should call GC AI as part of a workflow. It runs on credits, so no extra seat is required.
Multi-turn conversations work the same way as chat in GC AI. An admin turns on access in Integrations. Your team creates an API key for REST use, and that key carries the same permissions as the person it belongs to.
Use GC AI as a skill in Claude or ChatGPT
Claude and ChatGPT can pull playbooks and documents from GC AI during a conversation, so answers come back against your company's real agreements without anyone leaving that tool.
Do you need the API if your team already has seats?
Probably not for day-to-day work. The Slack connector, the Word add-in, and the web app already cover that, free with the seat. The API is for people without seats, for systems that run without a human starting them, and for AI clients.
Example use cases
Here are a few ways teams put GC AI to work.
-
Contract risk review for deal and procurement teams: each incoming contract gets structured findings before legal opens the file.
-
Inbox auto-review against your playbook, so checks are ready when a reviewer arrives.
-
Self-serve policy Q&A for employees across the company, with cited answers.
-
Legal request triage that classifies, risk-scores, and routes work in seconds.

Credits, privacy, and control
Usage is billed in credits, pooled across your organization. One credit is $5, which buys minutes of a $200/hr senior attorney's time. Each API chat message costs 1 credit. Each playbook check costs 0.1 credit, so a 30-check playbook review costs 3 credits.
API chats are private by default. They do not appear in anyone's chat history unless your integration is configured to save them, so batch reviews and bots stay out of your workspace. Save only the chats that need human attention, and store the chat ID when the call returns.
Your legal team stays in control: keys follow user permissions, only your playbooks and documents are accessible, and admins see usage.
Get started
Building an integration takes technical work: code, an AI coding assistant, a no-code path through Zapier or Make, or a partner in legal ops, IT, or engineering.
If you are an organization admin, you can turn on access yourself. Otherwise ask your admin to turn it on for you.
Then start with code someone else already wrote. The docs publish three working examples: a contract risk heatmap, a triage router, and a Slack bot. Copy one, point it at a playbook your team already runs, and you have a first integration reviewing real contracts.
