Parker vs. Filevine AI (LOIS): AI for Filevine and everything around it
Filevine’s LOIS runs AI agents across your Filevine matters. Here’s how it compares with Parker, which works with Filevine and the rest of your firm’s systems, so you can tell which one fits.
The short answer
Choose Filevine’s LOIS if your firm runs entirely on Filevine and plans to stay there. It’s built on Filevine’s own data and acts directly on your Filevine matters. Choose Parker if your work also lives outside Filevine, in email, shared drives, Slack, or a second case management system, or if you want a dedicated server and your choice of AI models.
Parker works with Filevine, so this isn’t about leaving it. It’s about how much of your firm the AI can see.

Where Filevine LOIS is strong
- Native to Filevine. LOIS acts directly on your matters, from tasks and deadlines to documents, and ties each action back to its source.
- Firm-wide agents. LOIS Console runs agents across every matter, not just one task for one user.
- Filevine’s data foundation. Filevine says LOIS is built on more than 40 million matters.
- Drafting in Word. LOIS for Word brings it into the documents your team already edits.
Why Filevine firms add Parker
- Not everything is in Filevine. Records arrive by email, files sit in Dropbox or Google Drive, and the team talks in Slack.
- Not every office is on Filevine. Firms that have acquired practices, or run a second system for workers’ compensation, need AI that works across both.
- They want their own server and model choice. Parker gives each firm a dedicated server and supports frontier and open-source models.
Filevine also has an official Claude connector. Here’s what it can and can’t do.
How Parker works differently
- Across systems, not inside one. Parker reads Filevine projects alongside your email and documents, so it sees the whole picture.
- Delegate by chat, email, or Slack. Ask for work the way you’d ask a colleague, and get it back in the same place.
- Firm-wide memory. Your templates and corrections carry forward to every matter.
- Background and stage-triggered work. Case audits and drafts can start on their own when a matter changes stage.
- Your attorneys stay in charge. Parker prepares the work for review. Nothing is filed or sent without approval.
How to decide
- Map where a typical case’s information lives. If it’s nearly all in Filevine, try LOIS. If it’s spread across systems, try Parker.
- Run the same assignment through both, like a case audit or a discovery response on a closed matter.
- Check what each one missed from email and documents outside Filevine.
- Get pricing in writing for your full team.
