Most of what you've done so far has been errands. Tonight's dinner, the tricky text, the letter interviewed and filed - in and out in ten minutes, done and gone. Errands are most of life, and a plain chat handles them beautifully.
But some things aren't errands. The family reunion that's still eight months out. The family history you keep meaning to get down on paper. The kitchen remodel with its three bids and its tile samples and its one load-bearing question. A thing like that isn't one conversation - it's forty conversations, spread over months, all needing the same papers and the same background. Today you learn where a thing like that lives.
The trouble with errand chats
Here's what happens without this lesson. In March you have a good long chat about reunion venues. In April you're back - new chat - and something's missing. Memory, from lesson three, hasn't failed you: it still knows you, your plain-words rule, your garden. What it doesn't have on the table is the stuff - the park list, the cousin count, the quote from the pavilion, what you decided about the date. All of that was in March's chat, and March's chat isn't in the room. A plain chat travels light, which is exactly right for errands and exactly wrong for a campaign.
Find the button
Along the side of your screen, in the same sidebar where your old conversations line up, hunt for the word Projects. Now point your mouse right at it. A small plus sign appears beside the word - it stays hidden until your mouse comes near, which is a funny way for a door to behave, but there it is. Press the plus and you're building a room. On the phone app, look for the same word in the menu. And as always, the furniture gets rearranged now and then; the word to hunt for is Projects.
A project is a room. Inside it, three things stay put: the conversations you have there, the files you've handed it, and a set of instructions that live by the door. Walk back in after three weeks away, and it's all still there. Nothing to re-explain. The table was never cleared.
Set up the room
- Name it for the goal. That's the first thing it asks. Not "misc" - a name that says what winning looks like. "Reunion, June." "Dad's story." "Kitchen, done by Thanksgiving."
- Answer the memory question. The same little box asks how this room should handle memory, and the answer it suggests - default - is fine. Default means the room shares notes with the rest of the house: everything it knows from lesson three works in here too. The other choice, project-only, means what happens in this room stays in this room. There are fine uses for a private room - planning a surprise party, say - but you don't need one today.
- Put the papers in. The project page has a spot for files - hunt for the word Sources. In they go, once: the venue quotes, the guest list, the photographed letters and bids - everything lesson six taught you to capture. Handed to the project, a file is there for every conversation that follows.
- Write the instructions at the door. This one is tucked away, and finding it teaches a trick worth keeping: when a setting isn't out in the open, look for the three little dots. Every app hides its extra buttons behind them - the junk drawer of the modern world. On your project's page, press the dots, choose Project settings, and there's a box marked Instructions. This is lesson two, but for one room: a few plain sentences about the job, not about you. "This project is planning a reunion for about forty people, three generations. Keep costs modest, keep plans simple, and always tell me what needs deciding next."
That last sentence is worth stealing for any project: always tell me what needs deciding next. Big projects stall in the gap between conversations - a standing instruction like that means every chat ends pointed at the next step.
While you're in that settings box, you'll see a switch or two we haven't talked about. Leave them be. Here's a rule that will serve you in every settings box you ever meet: the defaults are fine until you have a reason. You just did the two things that matter - the instructions and the name - and the door closes behind you with an X, top corner, as usual.
Working in the room
Once the room is set up, you just... talk, same as always. The difference is everything you say lands somewhere. Ask in May what the April conversation settled, and it can tell you. Say "compare the two bids again, but assume we skip the island" and it knows which bids, because they're on the table where you left them. The project remembers the project, so you don't have to.
The rule of thumb for what deserves a room: if you'll come back next week with the same papers, it's a project. If you won't, it's an errand, and the plain chat button is right where it's always been.
A few things you might be wondering
Isn't this what memory does? Close, but no - and the difference is worth having. Memory, from lesson three, is about you, everywhere: your taste, your garden, your short-answers preference, following you into every chat. A project is about one effort, in one place: these papers, this goal, this trail of decisions. You, everywhere; the reunion, in its room.
Does this cost money? No. Projects come with the free account. The free version holds fewer files per project than the paid ones - if you ever bump into that ceiling, that's a fine problem to have, and lesson eleven talks honestly about what paying gets you.
What happens when the project is over? Whatever you like. Keep the room as a record - there are worse scrapbooks than the whole story of the kitchen remodel. Or delete it - the delete button waits behind those same three dots, in Project settings - and the room and everything in it goes, same off switch as always. Your house, your rooms.
What this looks like in real life
Remember Nikki's tin box? Last lesson she rescued one fading recipe card. Somewhere between that card and the next one, the idea arrived, the way big projects always announce themselves: all of them. A real cookbook, printed, for the family, by Christmas. That's not an errand. So she made a room:
Nikki's project, named "Mom's cookbook, by Christmas" - the instructions at the door
"We're turning my mother's recipe cards into a printed family cookbook. I'll photograph cards as I find them. For each one: transcribe it exactly, her spelling and all, then a modern version underneath - real temperatures, real times, the steps she never wrote down. I've baked for thirty years; when her card and my judgment disagree, ask me instead of guessing. And always tell me what needs deciding next."
Now every card she photographs lands in the same room. The chat from the week she did the pies is still there next to the one where they argued about the kolache glaze. In December, she'll ask it to gather everything into chapters - and it will have the whole box in front of it, because she never let the table get cleared.
Look at what she put in those instructions: the goal, the format, her own authority - "ask me instead of guessing" - and the steal-this line about what needs deciding next. Four sentences, and every future conversation in that room starts smarter.
That's the lesson
Errands get chats; campaigns get rooms. Name the room for the goal, put the papers in once, set the instructions at the door, and then just keep showing up - the project holds the thread between visits. If something in your life has been too big to start, this is the shape it was waiting for. Next lesson steps back for a look around the neighborhood: ChatGPT, Claude, and that Copilot button that's been sitting on your taskbar unexplained. It's time you were properly introduced.
