Team Communication
Cover Letter Drafting
We focused on the highest-impact parts of an immigration practice: organizing cases, coordinating with clients and vendors, and drafting accurate cover letters.
From intake to filing: organized, exportable, and ready to submit.
CASE MANAGEMENT
Built based on how firms like yours actually work.
Collect and approve documents, organize cases your way with drag-and-drop, and give clients their own dashboard to upload files and track progress. Your team, your clients, and your vendors — all connected to the same case.
Drag and drop organization

Vendor file delivery
PDF or zip export
Export ready
Generate a single PDF with auto-generated table of contents, or export as a zip — organized exactly as you've structured the case.
High-level or case-specific views
View cases individually, as a kanban board, or in a table — whichever fits how your team tracks workload and deadlines.
User-based roles and dashboards
Attorneys and paralegals manage cases internally. Your clients have their own portal to upload documents and track case progress. Vendors can easily track requests an upload purchased documents into your case.

Choose the draft that fits your workflow
-
Fundamentals draft: AI-generated, document-grounded first draft. Ready for paralegal refinement and attorney review.
-
Professionally reviewed draft: Adds citation checks, consistency review, and a clean structure pass by an experienced writer.
-
Enhanced draft: Exhibit alignment, citation improvements, and structural refinement. Attorney strengthening required before submission
Our proprietary process uses strict extraction protocols and checks — both from AI and from experienced writers — to minimize the probability of error. Low enough that we back every draft with a 100% refund guarantee.
The services your case needs — in one place.
VENDOR MARKETPLACE
Keep all case files, communications, and vendor services on a single platform. No chasing documents across email threads or tracking down vendor deliverables separately.
Your workflow, your call
Set as much or as little direction as your clients need. Build a shopping list, recommend specific vendors, or handle purchasing yourself — clients can browse and buy independently or follow your guidance closely. Either way, all platform pricing is equal to or less than what they'd pay off-platform.

Vetted vendors only
Every vendor must hold AILA sponsorship or have 2+ law firm recommendations before joining the platform.
Guaranteed pricing
All vendors agree to charge clients no more than they would off-platform — negotiated at the marketplace level.
Documents stay in the case
Vendor deliverables arrive directly in the case file — no separate uploads, no lost attachments.
Free to start, with simple firm-wide plans as you grow.
PRICING
Storage is shared across your entire firm — not per user. The free tier includes full platform access, the vendor marketplace, and reduced cover letter pricing. Upgrade only when your firm needs more space.
Trusted by firms who demand accuracy.
