From the proposal to the Jour J.

The engagement

“We're getting married!” … now what?

A budget to frame, vendors to choose, family to align. ÆTHERNA sets the stage from day one.

The planning

RSVPs drag. Nobody has the same numbers.

Individual RSVP links, a seating chart that remembers, affinities and dietary needs.

The Jour J

7am, the stylist arrives. And the florist?

An hour-by-hour schedule, shared with whoever is running your day. You, you live it.

The 18-column spreadsheet, redone three times?

See it before you fix it.

Drag each guest from one table to another. Every table shows the seats taken and warns you when it overflows, and you keep one version of the chart per moment.

Everything you want to know.

Yes, completely. The free plan is forever — not a trial, not a free tier that converts to a subscription. No credit card required to get started. The free plan covers 1 wedding, up to 50 guests, 10 tasks and 10 vendors. You'll upgrade to Couple only if you want to go beyond those limits or export your data to Excel.
Yes, on both plans. You invite whoever you want: partner, bridal party, parents, wedding planner. For each person, you choose which pages they can access and whether they can edit them — page by page, read or write.
Your data stays accessible as long as your account exists — past wedding date or not. You can ask us to delete it at any time, and deleting your account wipes your space. The exact retention periods are detailed in our privacy policy.
For an intimate wedding, absolutely. For a large wedding, the 50 guests — with up to 10 tasks and 10 budget items — let you test all the features under real conditions before deciding whether the Couple plan is right for you.
Your data is securely hosted and is never sold to third parties, never used for advertising. Payments are handled by Stripe, PCI-DSS certified. Your wedding belongs to you.

Yes — whether you're on the couch or on the go. ÆTHERNA is designed for all your devices. Your space syncs instantly: what you update on your phone is visible in real time on your tablet or computer.
You invite whoever you want, however you like. For each person, you choose which pages they can access and whether they can edit them. Your partner sees everything, your bridal party sees what they need, your parents see what you decide.
Whenever you're ready. The sooner the better to make the most of the full checklist — but if you only need digital RSVP or a seating chart, you can join ÆTHERNA at any stage of your planning.
