No accounts, no servers, no tracking Whether you're decoding a JWT, pretty-printing JSON, or turning CSV into a Markdown table, TextNova gets it done in seconds.

What's new

Version 1.7.0 · Nov 8, 2026

A new look, transforms on just your selection, and transformers that take settings. • A fresh, calmer design and a new app icon, with Settings in the same style. • Select part of your text and a transform changes only that part, so you can chain several in a row. • New transformers you can set up: HMAC, Regex Replace, Caesar Shift, JSON Query and JWT signing. Keys and secrets are never saved to disk. • Also new: SHA-3, JSON to Swift, TypeScript and Go types, URL parsing and natural line sorting. • Run any transformer from Shortcuts without opening the app. • Type something that isn't a transformer into the palette to ask the on-device AI, which now works through long documents part by part. • Fixes for Korean, Japanese and Chinese input in the palette, safer session restore, and a crash on very large numbers in JSON.
