Figstack

Figstack is a discontinued AI coding companion, a web app that explained unfamiliar source code in plain English, translated it between programming languages, and drafted documentation for it.

Figstack ran on Codex, OpenAI’s 2021 code-generation model, and offered four tools. Explain Code turned a pasted code block into a natural-language summary. Language Translator rewrote a snippet in another language. Docstring Writer drafted a docstring for a function, and Time Complexity estimated a function’s Big O cost.

For a Python developer, that made Figstack a reading aid before anything else. An unfamiliar function pasted into the web app came back explained in prose, or with the docstring it was missing.

Han Wang and Hahnbee Lee built the product in ten days and launched it on Product Hunt in August 2021, where it took the number one Product of the Day spot. Retention stayed low, and the founders pivoted to a docstring-writing editor extension that grew into Mintlify. Figstack is no longer available, and its domain now redirects there.
