The Private Wedding App ($19.99/month, or $189 once for lifetime access where nothing expires) fits couples who want the guest side and the plan joined up: one RSVP with meals, a severe-allergy question and plus-ones feeds the guest list, the seating chart and the catering line, each guest reads the invitation in their own language among up to three of 26, and a Wedding Planner AI reads your own wedding data. The Knot fits couples who want a free app around a large US vendor marketplace: its app is free with a website, digital invitations, RSVPs with meal preferences, seating and budget tools, and AI vendor recommendations from your saved favorites, while its help center says some text, such as the RSVP page, cannot be changed to another language and its pages do not state how long the site stays online.
The Knot is a free US wedding planning app with a wedding website and a vendor marketplace with reviews. The Private Wedding App is a full wedding planner with the invitation built in, where each guest's answer feeds the rest of the plan. Published by The Private Wedding App: we make one of the two, so every fact about The Knot below comes from its App Store listing, help center and press releases, read on 22 October 2026 and linked at the end.
Price, and how long the site stays online
The Knot's app is free, per its App Store listing, and its pages do not state how long a wedding website stays online. The Private Wedding App is $19.99 a month with a 3-day free trial, or $189 once for Lifetime; on Lifetime nothing expires, your invitation stays online and your planner stays open, with no time limit.
Planning tools and AI
The Knot's app lists a custom wedding website, digital invitations and save the dates, a guest list with RSVPs and meal preferences, interactive seating arrangements and budget tools, all around its vendor marketplace. Its AI recommends vendors from the inspiration you save (press release, September 25, 2025), and since February 3, 2026 it also runs a vendor-recommendation app inside ChatGPT across 24 categories.
The Private Wedding App joins the pieces: a guest's RSVP, with meals by course, a severe-allergy question and plus-ones per event, updates the guest list, the seating chart and the catering line of the budget at once, and the caterer day sheet prints plate counts and allergies by table. Its Wedding Planner AI reads your real date, RSVPs, budget and checklist, and makes the changes for you, with your confirmation.
Guests in several languages
The Knot's help center says you can change most titles and text to your language, except for special characters, and that some text, such as the RSVP page, cannot be changed. Its app is listed in English only. On The Private Wedding App each guest picks their language on one link, up to three of 26 per wedding, Arabic and Hebrew right-to-left included, and the RSVP and meal choices switch with it.
