Toast IDE Gets Markdown Spell Checking

Terminal app adds spell check — and the internet asks, “Wait, that’s news?”

TLDR: Toast, a new terminal-based editor, added spell checking for writing files and tried to pitch it as a helpful upgrade. Commenters instantly turned the release into a debate over whether this is a useful milestone or embarrassingly basic stuff that software should have had ages ago.

A tiny update to Toast, a new text editor that runs inside the command line window, somehow turned into a full-on comment-section identity crisis. The actual news is simple: Toast now underlines misspelled words in Markdown and plain text, alongside a bundle of built-in comforts like tabs, file search, previews, and a sidebar. In other words, it’s trying to be a ready-to-use writing and coding app for people who like living in their black terminal window instead of clicking around giant desktop programs.

But the real fireworks came from readers asking why anyone should clap for spell check in 2026-adjacent software. One of the loudest reactions was basically: this has been normal since flip phones were exciting. Another commenter went even further, saying their operating system has had this kind of thing available for more than twenty years, so why is it being treated like a blockbuster launch? Ouch. The vibe was less “congrats” and more “are we seriously doing ribbon-cutting ceremonies for seatbelts now?”

And then, because the internet can never stay serious for long, the thread swerved into comedy. A linked GitHub issue featuring the mysterious phrase “dream mode???” became the accidental crowd-pleaser, with one commenter delighted by the wonderfully vague chaos. So yes, Toast shipped spell checking — but the bigger story is the community split between ‘nice quality-of-life upgrade’ and ‘how is this not already basic hygiene?’
