About this appAI proposal
Plainplan is a simple floor planner for people who are not architects. Draw a room by typing its wall lengths, add doors and windows, then drop in furniture at its real size to see if it fits.
It is built for homeowners and renters planning a new sofa, a moved wall or a rearranged bedroom. There are no layers, no drawing standards and no training. It works on a phone while you stand in the room.
Public comments say professional tools like Revit are too costly and too complex for this, and that consumer apps often miss the mark. This proposal keeps to the few things casual planning needs and leaves the rest out.

- Why this name
- Plain and plan: a floor plan without the jargon. Two simple syllables that are easy to say and spell.
In the first version

Type-in room drawing
Enter wall lengths and angles, or drag corners. Rooms snap square by default, so a clean plan takes a minute.

PricingAI proposal
The material gives no competitor prices, only that Revit is called expensive. These tiers are a starting point to test, covering both the freemium and one-time purchase models it mentions.

What it could be worthEstimate
What a software business making this much sells for today, from real deals. Pick a monthly revenue.
If it makes
Worth about
$190,000
Sale range $132,000 to $263,000
$120,000 a year in revenue
From 87 software businesses listed and sold on Empire Flippers in the last year, revenue vetted by the broker: they sell for about 19× their monthly revenue, most between 13× and 26×.
Measured on profit, the middle deal is 32× monthly net profit: about 2.7 years of profit.
An estimate, not an offer or financial advice. A real price depends on profit, growth, churn, how much of the work is the owner's, and the buyer.
How it would growAI proposal
How the product would reach new customers through its own use, and how the first ones would be found. A plan to test, not a result.
- Built-in loop
- Shared outputs. Users send view-only plan links or printouts to partners, movers, contractors and friends. The shared page carries the product name and a button to copy the plan and edit it.
- Do they become customers?
- Recipients are often people planning their own move or renovation and could become users. Test how many opened links lead to a copied plan and then a signup.
- First customers
- Renters and homeowners in the weeks before a move or a big furniture purchase, starting with people moving into a new apartment.
- Where to reach them
- Home and moving communities: Answer layout and fit questions in forums with a free plan link.
- Search content: Pages for questions like whether a sofa fits a room, each with a template plan to open.
- Hacker News: Share a Show post with the free tool, since the demand signals came from there.
- First milestone
- 500 plans created and 25 paying users on Home or Single project within 60 days of launch.
Why people already pay for this
- Public claimProfessional tools like Revit are too expensive and overly complex for casual home planning needs like furniture layouts and fit-checking.
- Public claimExisting consumer floor planning apps and websites fail to meet casual users' needs—they are either too expensive or more complex than required.
- Public claimThere is a market for simple, accessible, low-cost floor planning for homeowners doing casual spatial planning.

RisksAI inference
- CommercialFree consumer floor planners may already exist. The only evidence is public claims that they are too costly or complex; willingness to pay is unproven.
- TechnicalTouch drawing with snapping and clean mobile editing is hard to get right, and a clumsy canvas would lose the simplicity that is the whole point.
- CommercialCasual planning is occasional. Users may finish one project and leave, so monthly subscriptions may churn quickly.
- DataFurniture sizes are entered by hand or from a small generic set. Without catalogue data, fit checks depend on users measuring correctly.
