Big software.
Tiny tab.
Tools that respect your time.
We build software the way we wish more software was built — fast, private, and out of your way.
Faster than installing anything
Open the page, use the tool, close the tab. No downloads, no setup wizards, no system permissions to approve.
Private by design
Your documents and data stay on your device. WebAssembly lets us run real software without sending anything to a server.
No accounts required
Skip the signup forms. Skip the email verification. Skip the upsell popups. Just open and start using.
Built to last, updated weekly
These aren’t side projects. We ship updates almost every week and stand behind every tool with active support.
Browser-native tools. Free to start.
Browser extensions, full WebAssembly apps, web tools. Every one runs on your machine — and we’re still building more.
Anything Copilot
Chat with AI, translate pages, multitask between tabs — all without leaving what you’re doing.
Blitz Capture
Capture an entire scrolling page — even 10+ screens long — pixel-perfect, in less than a second.
ZIZIYI Office
A real office suite running on your machine. No Microsoft account, no upload, no install.
Online MCP Inspector
A browser-based inspector for MCP servers. Debug, test, and explore MCP protocols without any install.
People who use these stick around.
“Thank you so much!! I was looking for the edge's copilot sidebar on my other browsers and finally found you. This one is actually better than the original one that's native to Edge. Excellent work, particularly the UI.”
“Me pase de opera Gx a Brave y me hacia falta la barra lateral con varias aplicaciones, esta extensión lo soluciono por completo y puedo tener cualquier pagina practicamente en la barra lateral.”
“Meilleur outils d'ia en sidebar que j'ai utilisé jusque là. Il s'intègre très bien à chrome.”
“Its great if you're a chrome user”
“Alway want a sidebar that work like Naver Whale one and this is close enough. But. Can we fully detach it? Make extensions work? Having navigation bar on both sidebar and popup windows?”
“希望能增加收藏夹的功能，这样不用专门在浏览器打开，然后再点侧边栏”
A small team that loves browsers.
ZIZIYI started as a side project — one extension, one stubborn belief that browser-native software was an underrated path. Three years later it’s four products used by twenty thousand people, and the same conviction.
We’re independent, self-funded, and small on purpose. No trackers, no ads, no upsells. We charge a fair price for the Pro features so we can keep building things we’re proud of, full-time.
