We build agentic workflows all day at ze1 — and we kept reaching for the same little utilities over and over. Token counts before sending a big prompt, pasting a spreadsheet into a markdown doc, that kind of thing. So we cleaned them up and put them here. They're free, they run in your browser, and hopefully they save you a few minutes too.
100% client-side. Every tool on this page runs entirely in your browser. Your data is never sent to a server, never stored, never logged. Paste anything — it stays on your machine.
These tools are built by ze1, a no-code platform for orchestrating AI agents and workflows.
If you're building with LLMs, you might like what we're working on.
