Death by PowerPoint? Not this time
Show HN: Bento - An entire PowerPoint in one HTML file (edit+view+data+collab)
This one-file slide app has fans cheering freedom — and critics yelling “why so much AI?”
TLDR: Bento turns an entire presentation into one file you can open, edit, and keep, which made many commenters cheer the idea of actually owning your software again. The only real drama: skeptics were instantly annoyed by all the AI talk and the file’s suspicious-looking wall of encoded text.
A tiny internet soap opera broke out after Bento showed up on Hacker News with a big promise: your whole presentation lives inside a single HTML file — the slides, the editor, the viewer, even the saved data. In plain English, that means one file you can open almost anywhere, tweak on the spot, and keep without signing your life away to a cloud subscription. Unsurprisingly, a big chunk of the crowd reacted like they’d just seen a hero kick down the door of modern software. One fan called it “a breath of fresh air” in an era where “you rent everything, own nothing,” while another said their consulting-world brain basically exploded with gratitude.
But this being the internet, the lovefest lasted about three seconds before the side-eye arrived. The biggest drama magnet? AI, of course. One commenter demanded to know why the homepage mentions AI more than 20 times and, even spicier, why it mentions AI at all. They also looked at the long wall of encoded text inside the file and basically went, “Why does this look so suspicious?” That turned the thread into a classic tech-community split screen: one side cheering digital self-reliance, the other squinting at the packaging like it might be hiding a gimmick. Meanwhile, the creator jumped in to explain how it works in human terms: there’s readable slide data near the top, and the rest is the app bundled inside. The nerdy cherry on top? Someone immediately tried to recruit Bento into the growing gospel of the single-file web app movement.
