Where the other apps are stronger than Wedding Co-Pilot
- Vendor marketplace: The Knot and Zola let you browse vendors on their platforms. Wedding Co-Pilot has no vendor directory; you add the vendors you found yourself.
- Registry: Zola, Joy and The Knot run full registries with cash funds. Ours is a gift wish list: guests open your link and claim an item, but there is no cash fund or store.
- Native mobile apps: The Knot, Zola, Joy and Losava have app-store apps. Wedding Co-Pilot is a web app that runs in the phone browser.
- Guest invitations: Joy sends online save-the-dates and invitations for free and handles hotel room blocks.
- Free plan limits: our free plan allows 30 guests, 3 vendors and 3 AI messages a month; online RSVP and shareable links need a paid plan.
- Chat-first planning: Losava is built around one AI conversation that acts across the whole plan and writes, sends and follows up on emails to vendors. Our AI analyzes and generates inside each module (quotes, budget, seating, timeline) and answers questions in a chat, but it does not write to vendors for you.
Where Wedding Co-Pilot is different
- It reads vendor quotes and contracts: paste the text and the AI pulls out price, inclusions and terms, and flags high, medium and low-risk contract clauses in plain language.
- Seating knows who should not sit together: the conflicts you mark between guests feed the seating optimizer and its warnings.
- The budget is tracked against market ranges, with estimate versus actual, deposits and an AI that knows your numbers.
- A lifetime option: $99 once instead of a subscription.
- A planner plan for professionals who manage several weddings ($49/month).
- It works from ChatGPT and Claude through our free MCP server, and your data is hosted in the EU.
How to choose a wedding planning app
- Still looking for vendors in the US? Start with The Knot's marketplace.
- Want a free website and registry above all? Zola and Joy both cover them at no cost.
- Prefer to talk to one AI that runs the plan? Try Losava.
- Already have quotes, a contract or a guest list, and want AI to check the numbers, the clauses and the seating? Open Wedding Co-Pilot's demo wedding, no sign-up needed.
- You can combine them: for example keep the registry in one app and plan the budget and seating in another.
