PUNE. — Aarav Mehta, an engineer and occasional writer who has been making things on computers since the autumn of 2019, this week released Threadwell v0.4, an opinionated reader for long essays. The release marks the largest single artifact in his catalogue to date, and the third he has shipped at his own slow tempo of roughly one substantial thing every six weeks.
Asked, after the launch, what he was working on next, the engineer reportedly said that he was “mostly going to keep going,” and that he was in no particular rush to release anything else.
The catalogue, which now spans eleven shipped artifacts and fourteen published essays, may be examined in full in the pages that follow.
The reader was built solo over six weeks of nights in late 2024, launched in private beta in February of 2025, and continues to receive small typographic revisions every few weeks. It is, according to its author, “the largest thing in the file cabinet,” preserved as built.
