About this appAI proposal
Plotline generates full house floor plans and exterior elevations in seconds from your lot size, square footage and the rooms you want. Change a room, move a wall or try another roof, and the plan updates so you can compare options the same day.
It is made for homeowners, small developers and builders who now start from stock plans because custom design costs too much or takes months. Architects and designers can use it to show clients several directions before detailed drawing starts.
Every plan can be viewed in 2D and 3D, furnished, given materials, and exported as PDF and CAD files. Plans are drafts to review with a licensed professional and local code, not stamped drawings.

- Why this name
- Plotline joins the plot of land with the line of a drawing. It is short, easy to say and describes the start of a home design.

PricingAI proposal
The material gives no competitor prices. It only cites custom design at $10,000 to $50,000 as a public claim. These tiers are a starting point to test, priced far below that.

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
$194,000
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 share a plan link with family, builders, lenders or an architect. The viewer shows the plans and elevations with a small 'Made with Plotline' mark and a button to copy and edit the design.
- Do they become customers?
- Recipients such as partners and builders may become users if they want their own variations. Test how many shared-link viewers click to copy a design and start their own.
- First customers
- Small residential builders and spec-home developers who build 3 to 20 houses a year and now buy stock plans.
- Where to reach them
- Builder Facebook and Reddit groups: Offer free plan sets to members who post a lot and brief, then ask for feedback.
- Local home builders associations: Run short demos at meetings and offer pilot accounts.
- Hacker News and indie communities: Post a build-in-public demo to reach early adopters and self-builders.
- First milestone
- Ten small builders each pay for a plan pack and export at least one plan to their drafter or client.
Why people already pay for this

RisksAI inference
- AIGenerated plans may break building codes or structural sense. Each plan needs clear draft labels and review by a licensed professional, and the generator needs rule checks.
- RegulatorySelling construction-ready drawings may raise licensing and liability issues that differ by region. Terms and wording must be checked with counsel.
- TechnicalTraining or tuning a plan generator and producing clean CAD output is hard. Early versions may need rule-based layouts plus AI assistance.
- CommercialThe material cites a similar product with a large claimed user base, so free competition may make paying users hard to win. Builders may prefer their usual drafter.
- DataGood plan training data may be scarce or have unclear licensing. Using copyrighted stock plans could create legal exposure.
