Mostly useful experiments, lightly supervised
Small browser tools and honest workflow notes for writing, launching, prompting, and debugging text.
Monkeybase is a practical browser lab. Clean your writing, inspect launch copy, structure AI prompts, and debug developer text locally without accounts or setup. Keep what works, leave the rest.
- Runs in your browser (local processing)
- No accounts needed
- Built for one job at a time
Your input stays in the browser — nothing is sent to a server. Privacy policy.
Start here
Pick the job, then paste the mess.
Five starting paths for the most common jobs: writing, developer cleanup, prompting, launch copy, and building a tiny tool.
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 launch copy
Check launch copy
Paste a landing page draft and flag vague promises, urgency, and missing proof.
For makers
Ship a tiny tool
Go from a vague idea to a scoped brief, a clear CTA, and an honest launch caption.
See the difference
One vague claim. Two quick checks. A publishable sentence.
Before
“The revolutionary platform that transforms your team's productivity. Guaranteed results for every team.”
After two checks
“Review launch copy for vague claims before you publish. Flags absolute promises and missing proof locally in your browser — no account needed.”
- Tools run locally.
- Notes show the method.
- Results are only claimed when measured.

Open sectionCommon questions
Are the tools free to use?
Yes. Every tool runs free in your browser. There is no paid tier, no usage limit, and no account required.
Does pasted text leave my browser?
No. Every tool processes your input locally. Text you paste is never sent to a server. Standard analytics tracks page visits, not tool content. See the privacy policy for details.
Do I need an account?
No. There are no accounts, sign-ups, or sessions. Paste text, get a result, and leave when done.
What is the difference between tools and experiments?
Tools are stable utilities with a single clear job — clean text, format JSON, generate a slug. Experiments are early-stage ideas currently being evaluated. Both run locally. Experiments may change or be removed if they do not prove useful after testing.
Can I rely on tool output without reviewing it?
Use the output as a starting point, not a final answer. The tools flag patterns, apply transformations, and surface options — they do not verify meaning, factual accuracy, or contextual judgment. Review the result before publishing or acting on it.
