What this looks like today
Everything you'd expect from Castia Legal
The features you'd want from any tool in this category — because this is a product, not a plugin.
Contract repository
Every agreement in one place, with parties, dates, value, and status on the record.
Matter management
Track matters, counterparties, external counsel, and spend from instruction to close.
Clause library
Your approved positions and fallbacks, versioned — so the business drafts from the right starting point.
Review & approval workflows
Route contracts by value and risk, with escalation and a signing trail that stands up.
Compliance register
Obligations, policies, and attestations tracked with owners and due dates.
…and everything you can’t get anywhere else
Castia Legal is built on the Castia platform — so enterprise search, knowledge AI, reporting, workflow automation, and agents all apply directly to your work.
Contract analysis
Read any contract and extract parties, term, notice, liability caps, indemnities, and every obligation it creates.
Clause-level search
"Which contracts have uncapped liability and auto-renew?" — answered across your entire repository in one query.
Redline review
Compare an incoming draft against your standard position and flag every deviation, ranked by risk.
Obligation agents
An agent that watches every deadline, notice period, and attestation — and tells you before it's late.
Audit-ready evidence
Assemble the evidence pack for an audit or a regulator from records you already hold, with the trail intact.

From question to finished work
Ask in plain language. Castia does the reading, the reconciling, and the drafting.
You ask
Which of our contracts have uncapped liability?
Castia delivers
Nine contracts with uncapped or inadequately capped liability, ranked by contract value, each with the exact clause quoted and a link to the executed document.
What changes
Connects to the systems you already run
Castia Legal reads from the tools your team already uses — no migration required.
Open source. Free to start. Pay only for what the AI does.
Contract lifecycle tools charge per legal seat, so the business teams who actually sign things stay outside the system. Castia charges for usage — put every commercial owner inside the process.
