Frequently asked questions
Can't find what you're looking for? Write to us at contact@ultratoolsai.com.
Is UltraTools AI free to use?
Yes. Every tool is free to use, with no account required.
Are my files uploaded anywhere?
No. Images, documents, and text are processed locally in your browser. The only exception is Speech to Text: some browsers, such as Chrome, send microphone audio to their own speech service to turn it into text.
Why does an AI tool take longer the first time?
AI tools download their model once (typically 7–130 MB). Your browser caches it, so later uses start much faster and the model never needs to be downloaded again.
Which devices and browsers are supported?
All tools work in modern versions of Chrome, Edge, Firefox, and Safari. AI tools run fastest on desktop browsers, and speech recognition works best in Chrome, Edge, and Safari.
Can I suggest a new tool?
Absolutely. Send your idea to contact@ultratoolsai.com and we'll consider it for a future release.
How do I report a bug or get support?
Email contact@ultratoolsai.com with a short description, the tool name, and your browser.
