Voice Typing Tools FAQ

Short answers before you choose a calculator, checker, or setup guide.

Are the OpenTypeless voice typing tools free?

Yes. The tools page is free to use and does not require an account. Some tools help estimate provider costs, but they do not charge you directly.

Do these tools replace the desktop app?

No. They help you choose providers, prompts, hotkeys, and setup options. The desktop app is still the main product for global voice input, AI polishing, and Ask Anything.

Which tool should I use before installing OpenTypeless?

Start with the voice WPM test, STT cost calculator, and STT provider comparison. They explain whether voice input fits your workflow and which provider setup is likely to work best.

Do the tools consume cloud words?

Most tools are calculators, references, or builders and do not consume OpenTypeless cloud words. Hosted desktop STT, LLM polishing, or Ask Anything usage can use cloud words depending on provider setup.

Built for Real Voice Input Users

These tools are built and maintained by the OpenTypeless team — the same people who built the free, open-source voice input app. All tools are free forever and work without an account.
