Show HN: ANSItype – Browse 900 TheDraw fonts in the browser

Mon, 03/02/2026 - 9:53am

There's a project called tdfiglet that allows you to preview TheDraw fonts (https://www.roysac.com/thedrawfonts-tdf.html) from a CLI, but I wanted a web view to quickly browse through the font archive.

Type some text, pick a font, get ANSI color or plain block output, and filterable by style.

Show HN: I built a 100% client-side tool to automate Excel-to-PDF filling

Mon, 03/02/2026 - 9:52am

Hi HN,

I noticed people manually copy-pasting data from Excel into PDF forms, but existing solutions require uploading sensitive data (employee info, invoices) to third-party cloud servers.

I built FormFill to do all the heavy lifting entirely in the browser using pdf-lib. It parses the Excel file, maps the columns to your created PDF fields, and generates a .zip of filled PDFs locally.

Because it's 100% client-side:

1. User data never leaves their device.

2. Server computing costs are essentially $0.

You get a few free batch exports just by visiting (no sign-up required). I'd love to hear your feedback on the mapping UI and the pure frontend approach!

Show HN: Rushiram Finance – Privacy-first, client-side financial calculators

Mon, 03/02/2026 - 9:51am

Hi HN,

I spent 3 weekends building Rushiram Finance. I wanted a single, reliable place for financial planning without having to worry about my personal numbers being tracked, stored, or sold. As a fun note on the development process, I built this alongside Google Gemini, using it heavily as an AI coding assistant to help bring the project to life.

It features a suite of calculators for SIPs, loans, interest, and taxes.

The biggest technical priority was privacy. The financial calculators run entirely client-side, meaning your sensitive inputs never leave your browser. For full transparency: the site is hosted on Vercel and I use their built-in analytics for basic, anonymous traffic tracking, but absolutely zero personal or financial data is collected or sent to any server.

I’d love for you to try it out. Any feedback on the UI, the accuracy of the calculators, or suggestions for what to add next would be greatly appreciated!
