Beautiful Digital Invitations & Greetings

Start strong. Choose from free or premium designed templates or upload your own photo and video invitations. Every celebration deserves an entrance.

RSVP Tracking That Actually Adds Up

Most apps tell you how many people are coming. Jillii tells you how many adults, how many kids and how many toddlers — so you know what to order, how many chairs to pull out and whether you need a kids' table. Responses update in real time, so no more chasing people over text.

Guest Lists Without the Spreadsheet

Names, contact details and responses stay organized in one place, whether you're hosting eight people or eighty.

Co-Hosting, So You're Not Doing It Alone

Add a co-host and give them real access, not just a heads-up. Share the guest list, the checklist and the updates — with admin permissions you control.

Event Messaging & Group Chat

Send announcements, answer questions and start group or one-on-one conversations, all inside the event. The details stay where people can find them instead of scrolling back through a group text.

Gift Tracking

Struggling to remember who gave what? Track gifts and thank-you notes as they come in, so nothing gets lost in the wrapping paper.

Checklists You'll Actually Finish

Break the prep into steps, keep track of what's left and check things off as the day gets closer.

Shared Memories, After the Confetti

Capture, share, and relive the memories that matter. Hosts have full control over content approvals, ensuring every shared memory aligns perfectly with your vision.

Private, Ad-Free and Moderated

No ads. No clutter. We don't sell your personal information. Jillii has a zero-tolerance policy for objectionable content — hosts can approve media, remove posts, and report or block users at any time, so every celebration stays a safe one.
