Mostly useful experiments, lightly supervised
Small web experiments that do useful work before taking themselves too seriously.
Monkeybase is a browser lab for quick text workflows, odd little tools, and experiments that may or may not deserve a tiny lab coat. Paste text, press buttons, keep what works.
- Runs in your browser
- Mostly harmless
- Built for one job at a time
Privacy by default: your input stays in the browser. No account ceremony, no server confessional.
Start here
Pick the job, then paste the mess.
Four starting paths for the most common jobs: writing, developer cleanup, prompting, and launch copy.
For writers
Clean rough copy
Paste messy text, normalize it, count it, then move into readability or diff checks.
For developers
Inspect developer text
Format JSON, compare changes, test patterns, and decode strings without leaving the browser.
For AI work
Tighten a prompt
Paste a vague ask and turn it into role, task, format, and constraints.
For makers
Check launch copy
Paste a landing page draft and flag vague promises, urgency, and missing proof.
Latest from the lab
Fresh from the bench. Some of it may survive.
