Comparison
Frix vs Clio
Clio is the most widely used practice management system for small and mid-sized firms: matters, time and billing, documents, client intake through Clio Grow, and Clio Duo as its AI assistant. Frix covers matters, documents and intake too, and adds what Clio does not have: a public Law Library with a citator, and an AI that researches the law and reads your files with citations. Clio is stronger on billing and its integration marketplace.
Choose Frix if
- You want research and drafting inside the same system as your matters, with citations you can open.
- You want an AI phone assistant answering calls and booking consultations, not only a web intake form.
- You are starting out and want to begin free.
Choose Clio if
- Time tracking, billing, trust accounting and payments are the centre of your practice.
- You depend on Clio's integrations (accounting, e-signature, court forms) and its app marketplace.
- You already run on Clio and do not need legal research in the same tool.

Where Clio is the safer choice
If billing is the heart of your firm, Clio is the more mature product and Frix does not try to replace it. Trust accounting, invoicing, payments and the accounting integrations are things Clio has spent years on. The same goes for its marketplace: if your workflow depends on a court-forms or e-signature integration that lives there, that is a real reason to stay.
Where Frix is different
Frix starts from the work rather than the ledger. The phone assistant takes the call at 9pm, asks the questions a personal injury intake needs, and the matter is waiting in the morning. Donna reads the file, researches the law in the library, and drafts the demand in Word with citations. The Law Library is free and public, so research stops being a separate subscription. We wrote about what an intake assistant should and should not do in AI phone intake for personal injury firms.
Frequently asked questions
For matters, documents, intake and research, Frix covers the same ground and adds a Law Library and a citing AI. Frix is not a billing or trust accounting system; firms that need those keep Clio or an accounting tool alongside.
