The problem<br>Personal finance apps got too hungry for your data.<br>Most personal finance tools keep moving more of your financial history away from your Mac. CentProof takes a quieter path: you import the PDF statements you already download, and the app does the work locally.

Your bank statements stay on your Mac. So does the AI.<br>Your financial data stays on your Mac<br>No bank password<br>No cloud sync<br>Local AI by default

Local-first, period<br>Your statements, database, and AI questions stay on your Mac.

Local AI by default<br>Ask questions, clean up merchants, and summarize patterns without sending financial data off your Mac.

Reconciled to the cent<br>Statement math is verified before you trust the data.

Direct Mac app<br>Downloaded from centproof.com, signed and notarized for macOS.

Workflow<br>How it works<br>CentProof starts with local PDF statements and ends with searchable, reportable records you can verify.

01Download CentProof<br>Install the signed and notarized Mac app.

02Drag in PDF statements<br>Use the statements you already download from your bank.

03Verify reconciliation<br>CentProof checks statement math down to the cent.

04Search, tag, and organize<br>Clean up merchants, entities, categories, and notes.

05Ask CentProof questions<br>Run local AI queries with source rows shown underneath.

06Export reports<br>Create CSV, JSON, OFX, QFX, and PDF reports from local data.

Who it's for<br>Built for the privacy-conscious and the unsyncable.<br>If you've ever closed a finance app because it wanted your bank password, broke on your credit union, or felt like an Electron tab pretending to be a Mac app — you're who CentProof is built for.

The Privacy Pro<br>Engineers, lawyers, and anyone who refuses to hand a bank password to a third-party aggregator.<br>If a 'connect your bank' button is a hard no for you, CentProof never asks. It works from the same PDF statements you already download for taxes.

The 1099 Freelancer<br>Solo workers stitching multiple clients, business and personal cards into one searchable history.<br>Drop in statements from every account, tag once with Smart Tagging, and search across years of activity. No cloud sync, no per-seat pricing.<br>Read the freelancer playbook →

The Mac Power User<br>Native speed, keyboard shortcuts, and zero web-wrapper latency.<br>Not Electron. Not a browser tab pretending to be a Mac app. CentProof is a Tauri-built Apple Silicon native binary that respects your machine.

The Unsyncable Bank<br>Credit union members and foreign account holders whose banks constantly break Plaid integrations.<br>If your bank doesn't sync reliably with mainstream finance apps, CentProof works directly from the PDF — and you keep the same workflow whether your bank is Chase or a regional credit union.

The Co-Mingled Couple<br>Partners splitting expenses across joint and individual accounts without per-seat SaaS bills.<br>Import statements from both partners' accounts on one Mac. Tag transactions by entity (Joint / Mine / Partner's) and run settlement reports without paying for every member separately.

Features<br>Statement-based finance, not a cloud feed.<br>CentProof is built around PDF import, reconciliation, local AI, source rows, and reports you control.

PDF in, verified data out<br>Drop in the same PDF statements you already download for taxes. CentProof reads BofA, Chase, Citi, Apple Card, Amex, Discover, Capital One, US Bank, and Wells Fargo — then reconciles each statement against its own opening and closing balance. Math is verified before you trust the data.

Tag once, applies forever<br>Raw bank descriptions like 'AMZN MKTP US*4F8H2' are hostile to humans. CentProof's Smart Tagging learns 'AMZN MKTP' means Amazon — and applies it to next month's slightly-different string automatically. You stay in control of the final approval.

Ask plain-English questions. Answers stay on your Mac.<br>A 3-billion-parameter AI runs natively on Apple Silicon. Zero cloud calls to OpenAI or Anthropic. Ask 'how much did I spend on groceries last quarter' and CentProof returns the answer with source rows so you can check the math.

Catch the subscriptions you forgot you had.<br>Detect repeating charges across imported statement history — merchant, cadence, and amount changes. Spot subscription price hikes, annual-fee bumps, and that one streaming service you've been paying for since 2022.
