Design a Kitchen Together, Live

Your partner is at work, your contractor is across town, and the design is on your screen. Invite them into it: they watch every change as you make it, point at what they mean and talk it through on a call — and nobody overwrites anybody.

Most kitchen designs are argued over in screenshots. One person draws, takes a picture and sends it to a group chat, and by the time the contractor replies “move the one on the left” the design has moved on and nobody is sure which left they meant. There is a better way: put both of you in the same design at the same time. One of you drives, everyone else watches the changes land as they are made, and the conversation happens on top of the drawing instead of around it.

The short answer

Save the design, click 👥 Contacts on the 2D tool strip and press Invite beside the person. They get a message with an Open the design button and arrive as a watcher: they see every change you make, live, with your mouse on their screen. Hand over lets them drive, and as the owner you can Take back at any time. Chat, voice messages and a voice call for up to six people sit in the same panel. You both need a free account — guests cannot invite or be invited — and the invite link works for thirty minutes.

01 The link

Why the share link says “Not authorized”

Every saved design has an ID and a share link, and it is natural to paste the link into a message and assume the other person will see what you see. Usually they will not. A design is private to the account that saved it, and the link opens only for people who are allowed in:

  • You, on any computer or tablet you sign in from.
  • A designer or installer you hired through Community, on the project they were hired for.
  • A contact you invited into this design — the rest of this page.
  • Anyone at all, once you publish the design to the Community gallery.

Everyone else is stopped at the door. Someone who is not signed in is asked to sign in, and a signed-in stranger sees Not authorized to view this project. That is deliberate: a kitchen plan is the layout of your home, and a link that has been forwarded twice should not open it. So when the link fails for your contractor, nothing is broken — they need an invitation, or a PDF.

02 Before you invite

Three things that have to be true first

  1. You both have a real account.Google, Apple or a six-digit code sent to your email — all free. A guest session is fine for trying the planner, but a guest has no contacts book, so it can neither invite nor be invited.
  2. The design is saved to your account.An unsaved draft has nothing for anyone to open. Until you save, the Contacts panel says so and offers nobody to invite.
  3. They are in your contacts.In Community → 📇 Contacts, type their sign-in email under Add a contact and press Send invitation. Contacts work both ways: they accept on their own Contacts page before either of you appears in the other’s book, and they must have signed in to Flip Kitchen once so the address belongs to someone.Why the extra stepIt is the same line that keeps strangers out of your messages. You add a contractor once and then invite them into any design you like.

Only the owner of a design can invite people into it. If you opened a design someone else owns, the panel tells you so instead of listing your contacts.

03 Inviting

Invite, and what the other person sees

With the design open in 2D, click 👥 on the tool strip, next to the 📍 comment button. The left panel opens with three tabs — 💬 Chat, 👥 Contacts and 🖼 Album — and the Contacts tab lists your book. Press Invite beside a name.

  • They get a message. A line lands in your one-to-one thread in Community Messages — I’d like you to look at my kitchen design with me — with an Open the design button, plus a notification on their devices.
  • The link works for thirty minutes. Once they are in, it stays good for as long as they are in the design, and for thirty minutes after they leave so they can come back. Beside their name you see how many minutes are left, then In this design while they are there; an expired invite offers Invite again.
  • They come in as a watcher. An invited person never takes control on their own. You decide whether they operate.
  • Removing someone from your contacts ends it at once. The pass is checked every time the design is opened, not only when the invitation is sent.

The same live session switches on by itself whenever two people who already have access open the same saved design — you and a designer you hired, or simply you on a laptop and a tablet at once. No invitation is needed for that.

04 Who drives

One person operates, everyone else watches

Two people dragging the same cabinet in different directions is how designs get wrecked, so there is always exactly one operator. Whoever opened the design first operates; everyone who arrives later watches. A bar across the top says who is doing what: You’re operating with the names of the people watching on the operator’s screen, and the operator’s name on everyone else’s.

  • Watchers look, they do not change. They can orbit the 3D view, switch to the plan or the elevations, select things to read their sizes and open the quote. If they move something anyway, it slides back with a note that someone else is operating.
  • Follow is on by default. A watcher’s view follows the operator’s, so you are both looking at the same wall. Turn Follow off to wander and on again to catch up.
  • Asking for the wheel. A watcher presses Request control, and the operator — or the owner — gets a card with Allow and Decline.
  • Handing it over. The operator passes control to anyone in the design from Hand over ▾; their last change is saved first.
  • The owner can always take it back. Take back needs nobody’s permission — it is your design.
  • Walking away hands it home. If the operator’s tab sits in the background for two minutes, control goes back to the owner.

While other people are in the design, a few things belong to the operator alone: saving, rendering photos, and running AI Design or AI Suggestion. Anything that rewrites the whole design or spends coins has one person’s name on it.

05 Pointing

Say “this one” and mean it

Half of every design conversation is pointing. The operator’s mouse appears on everyone’s screen as an open hand that closes into a fist while it drags. It is placed in the design’s own coordinates rather than the screen’s, so it sits on the same cabinet whatever each person’s zoom — in the plan, in 3D and in the elevations.

Watchers get a pointer of their own. Press 🔦 Point and the operator is asked to allow it; the owner does not have to ask. Then click to drop a “look here” ripple, or drag to circle something — the mark fades after a few seconds. A pointer only points. It cannot move or change anything.

A good first ten minutes

Let the person who knows the room best drive. A contractor who has been on site will spot the wall that is really 3/4″ shorter, the vent where an upper is meant to go, the dishwasher with no room for its door. Hand them control, watch, and point; take it back when it is your turn to decide.

06 Talking

Chat, voice notes and a call, inside the design

  • Chat. The 💬 tab is a conversation attached to this design — everyone in this design sees it. It works on any saved design, not only during a live session, so a question left on Tuesday is waiting when the other person opens the design on Wednesday. A message can run to 2,000 characters, and the design keeps the latest 500.
  • Voice messages. Press 🎤 to record up to two minutes. Where the browser can, a transcript is added under the clip.
  • A voice call. During a live session, 📞 Voice call starts a call that anyone in the design can Join — up to six people — with Mute and Leave. The browser asks for the microphone only when you press Join. The audio goes directly between the browsers and is not recorded.
  • Translation. Each person reads other people’s messages in the language their planner is set to — English, Chinese or French — with Original and Translation to flip between them. It helps when the homeowner, the designer and the installer do not share a first language.
07 Notes that last

Pins and a to-do list for after the call

A call ends; the list of things to change should not. The 📍 button in 2D, 3D and the elevations pins a comment — typed, or a voice note with Hold to talk — to the exact spot it is about, and every pin goes on the design’s shared Comments & to-do list.

  • Four states. A pin moves through To do, In progress, Check it and Done. Whoever picks it up presses I’m on it, then Done — please check, and only the person who raised it can Confirm done or Reopen it.
  • What moved since last time. See changes lists the pins that changed since you last looked.
  • Who can write them. Pins need edit access: you, and a designer or installer you hired through Community. An invited contact can read every pin and answers in the chat.

The 🖼 Album tab collects every render of the design, whoever made it, for everyone in the design to see and download. Whoever renders uses their own coins, and the album keeps the latest 300.

08 Collisions

When two people changed it at once

A live session saves the operator’s work for you — whenever control changes hands, and thirty seconds after the last change. While two or more people are in a design, nobody can overwrite it from a separate copy; that save is refused with a note to ask for control in the bar at the top. Two moments still need a decision from you:

  • You changed it on your own first. If you had unsaved changes when someone else turned out to be working on the same design, you see Someone else is editing this design right now. Save mine as a copy keeps your changes as a new design; Drop mine & join lets them go and joins the session.
  • A session ended before it saved. The next time you open the design: Changes from the last time you edited together were never saved, with Discard or Load and save them.

When the last other person leaves, the bar says Everyone else left — back to editing on your own, and the planner behaves exactly as it did before.

09 Everyone else

For the person who will never sign in

Not everyone wants an account to look at a kitchen — a parent, a countertop shop, a condo board. Two things work for them:

  • A PDF. ⬇ Export builds a drawing set — the elevations, the top view, the countertop drawing, 3D photos — that opens on anything. It is a snapshot, so send a fresh one after big changes. How to read the drawings.
  • The gallery. 🌐 Publish to Community makes the design public: anyone can open it and look round, with no account, and it appears under a nickname rather than your email. Keep it for designs you are happy to have public.
10 Privacy

What is kept, and for how long

The chat belongs to the design: it is kept for up to a year after its last message and deleted with the design. Voice calls are not recorded. Chat lines are translated by an AI translation service and the result is cached, so the same line is not sent twice; the privacy policy lists the services involved. Your mouse and pointer are shown only to the people in the design while you are in it.

Straight answers

Can two people work on the same kitchen design at the same time?+

Yes. In the Flip Kitchen planner, open a saved design, click the Contacts button on the 2D tool strip and invite someone from your contacts. They see every change live, with your mouse on their screen. One person operates at a time and the others watch; the owner can hand over control or take it back whenever they like.

How do I share my kitchen design with my contractor?+

Add them as a contact in Community, then open the saved design, click Contacts on the 2D tool strip and press Invite next to their name. They get a message with an Open the design button and watch your changes live. If they do not want an account, export a PDF of the drawings and send that instead.

Why does my contractor see “Not authorized to view this project”?+

Because a saved design is private. The share link only opens for you, a pro you hired through Community, a contact you invited into the design, or anyone once the design is published to the gallery. Invite them from the Contacts panel, or send them the PDF from Export.

Does the person I invite need an account?+

Yes, a free one: Google, Apple or a code sent to their email. Guest sessions have no contacts book, so a guest can neither invite nor be invited. They also need to accept your contact request and to have signed in to Flip Kitchen once.

Can the person I invite change my design?+

Only if you let them. Invited people arrive as watchers: they can look around in 2D, 3D and the elevations, but any change they try is put back. If you hand them control they can edit, and their changes are saved to your design; as the owner you can take control back at any moment.

What happens if we both edit at the same time?+

You cannot: there is one operator and everyone else watches. If you had made changes on your own before someone else opened the design, the planner asks whether to save yours as a copy or drop them and join. The session saves when control changes hands and thirty seconds after the last change.

Can we talk while we look at the design?+

Yes. The chat panel inside the design takes text and voice messages of up to two minutes, and during a live session a voice call lets up to six people talk while they look. The browser asks for the microphone only when you join the call, and calls are not recorded.

Is the chat translated?+

Yes. Each person reads other people’s messages in the language their planner is set to, English, Chinese or French, with Original and Translation buttons to flip between them.

Does designing together cost anything?+

No. Inviting, watching, chat, voice messages, calls and comment pins are free for every account. The only thing that uses coins is rendering photos, and whoever renders uses their own.

Your turn

Stop describing it. Show them.

Ten minutes in the same design replaces a week of screenshots — and the decisions end up in the drawing, not in a chat thread nobody can find.
