01 · The why
Most online finance and PDF tools fall into one of two camps. Either they paywall everything past three uses — or they upload your files to a server you’ve never heard of, in a country you didn’t choose, for processing that could just as easily run on your laptop.
Neither felt right when we needed quick, dependable utilities for day-to-day finance work — generating a tax invoice, pulling line items out of a bank statement PDF, building a quick break-even sheet for a new product, signing a contract before sending it.
So we built Sonchoy: a growing set of focused, single-purpose tools that run entirely in your browser. Each tool does one job well, with finance-aware defaults — not generic templates.
02 · How we work
01
Every generator and extractor here runs at zero cost. We don't paywall the basics. The few links you'll see to paid services (like pdfFiller) are clearly labelled and only appear where they genuinely add capability beyond what a browser can do.
02
We have no upload pipeline. PDFs, statements, invoices, and spreadsheets are processed entirely in your browser via JavaScript. We can't see them because we never receive them. Read the Privacy page for the architectural details.
03
Each tool is shaped by how accountants, CAs, freelancers, and small-business owners actually work — GST/VAT slabs, invoice numbering schemes, P&L conventions, bank statement formats. Not generic SaaS templates.
04
Open a URL, do the job, close the tab. No account creation, no email capture, no onboarding flow. We measure success by how quickly you get the file you needed.
03 · What’s next
We’re adding new tools every few weeks — OCR, bulk processing, deeper accounting workflows, more contract templates. All free, all browser-side, all built around the same four principles above.
