Platform Lab

One prompt.
Tuned for your AI tool.

Pick the AI tool you write to and how far Typo may go. The lab runs the same token language as the Typo app, right here in your browser, and shows exactly what changes, what stays and what helps most in that tool.

What changed

Changes by level

Kept exactly

Runs in your browser. Nothing you paste is sent or stored. In the app, Typo fixes spelling first. This lab runs the token language on the text as you pasted it.

How the lab works

Honest by design.

Same engine as the app

The lab runs a line-for-line browser port of the engine inside the Typo app. 830 test cases must give identical output in both.

Estimates, not bills

Characters are exact. Tokens are an estimate. Credits and bills are not measured, and shorter does not always mean cheaper.

Advice, not magic

The platform advice is a short summary of each provider's own public guidance. It never changes your text. We are not affiliated with any AI company.

Guides for your AI tool.

ChatGPT

Prompt optimization for ChatGPT

How to write shorter, clearer ChatGPT prompts: state the task, format and limits, keep repeated context in a Project, and let Typo trim the filler in the ChatGPT app and on chatgpt.com.

Claude

Prompt optimization for Claude

Keep Claude prompts focused: trim filler, keep sources and quotes intact, use Projects for recurring context and point Claude Code to exact files. Typo works in the Claude app and on claude.ai.

Lovable

Prompt optimization for Lovable

In Lovable, credits follow the work a request causes, not its length. Pick Chat, Plan or Build first, keep scope and acceptance criteria exact, and let Typo trim only the filler.

AI tools

One prompt, different AI tools

Why the same prompt behaves differently in ChatGPT, Claude, Lovable and Gemini, what Typo knows about the tool you use, and which level to pick for each kind of task.

Developers

Prompt optimization for developers

How developers can shorten prompts to AI coding tools without losing file names, errors, tests or constraints, and where Typo's token language helps and where it stays out on purpose.

Measurement

How we measure savings

What the numbers on Typo's token pages mean: characters are counted exactly, tokens are an estimate, and provider bills and credits are not measured. How to check real savings yourself.
