About this appAI proposal
Tallyroom is a budgeting app that runs its AI on your own computer. Import a bank CSV, and ask questions in plain words: where did the money go last month, what changed since spring, which subscriptions are new. No account is needed in local mode, and no transaction data is sent anywhere.
The totals are not guessed by the model. Sums, category rules and date math run in ordinary code. A language model reads your question and writes the answer, and a second model checks that answer against the numbers before you see it. If the check fails, Tallyroom says so instead of guessing.
It is for people on Apple Silicon Macs who now use spreadsheets or cloud budgeting apps and are uneasy about where their data goes. An optional paid tier adds bank syncing, built so transactions are not kept on a server.
- Tagline
- Ask your budget anything. Your numbers never leave this Mac.

- Why this name
- A tally is the old, honest way of counting money. A room suggests a private place where the books stay at home.
In the first version
Members say which features they would use. It tells PWAS what people want; it changes no score.
Ask in plain words
Type questions like "how much did I spend on food in March?" and get an answer with the transactions behind it.

Runs on your device
The language models run on your Mac. Local mode needs no account, sends no analytics and makes no calls out.
No member yet
Math done by code
Totals, splits and date ranges come from built-in rules, not from the model, so figures are exact.
No member yet
Second-model check
A separate model verifies each answer against your data. Answers that fail are flagged, not shown as fact.

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
- No loop in the product. Tallyroom is a private tool, so its use creates no visible output to others. Growth comes from privacy-minded communities, write-ups on how the local checking works, and word of mouth.
- Do they become customers?
- Readers of posts and threads can become paying users directly. Test whether people who start in free local mode will pay the yearly fee for bank syncing.
- First customers
- Privacy-minded Apple Silicon Mac users who track money in spreadsheets, such as developers and independent professionals, who already export bank CSVs.
- Where to reach them
- Hacker News and developer forums: Share a technical write-up of the local model plus verification design and invite testers to a free download.
- Privacy communities: Post in privacy-focused subreddits and newsletters with a clear no-account, no-analytics statement.
- Mac app communities: Offer early access in Apple-focused forums and Discords, asking for feedback on answer accuracy.
- First milestone
- Two hundred active free users, and fifty of them paying the yearly fee for bank sync.

RisksAI inference
- TechnicalRunning models in a browser app needs WebGPU and a large first download. Speed and memory use on base Apple Silicon Macs may feel slow, and a native wrapper may be needed.
- AIThe claim that checking cuts wrong answers from 20% to about 1% is a public claim and is unverified. Accuracy must be measured on real bank exports before it is promised.
- DataBank CSV formats differ widely, and messy merchant names hurt categorization. Browser storage can be cleared by the system, so users need a backup path.
- PlatformPlaid terms and fees may constrain a design where transactions pass only to the device. Safari's storage limits on installed web apps may also apply.
- CommercialFree local mode may satisfy most users, leaving too few who pay for sync. Users with strong privacy concerns may also distrust any bank link.
