Side Reader
Side Reader is a Chrome extension that lets you read and interact with PDFs directly on ChatGPT, Claude, and DeepSeek websites. I built Side Reader because I got tired of the constant tab-switching between PDF readers and AI chat - copying text, switching tabs, pasting, repeat. It was driving me crazy. Over time, I added more features like custom highlight buttons, screenshot functionality, and local storage.
Side Reader launched on April 8, 2025 with 8 votes and more than 50% of that year's launches. The site was still online in September 2026, 1 year on.

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
