FAQ
Q1. What kind of extension is Hilightext?+
Hilightext is a browser extension that allows you to efficiently highlight, organize, and save text on web pages.
You can color-code or make important parts blink while reading, and review them later in a list, which greatly improves the efficiency of research and learning.
You can also freely change text and marker colors. Above all, the ability to replace words is its greatest feature.
Q2. Which browsers can I use?+
Available on Google Chrome.
If you experience any issues, please contact our support team.
It should generally work on Chromium-based browsers such as Microsoft Edge and Brave, but since we are still testing, we cannot guarantee full compatibility at this time.
Q3. Is account registration required?+
The free version allows you to register and use up to 50 words without an account.
If you want to increase the number of highlights or use additional features, account registration for a paid plan is required.
Q4. What can I do with the paid plan?+
You can increase the limit of highlightable characters and import/export your listed word data via CSV.
Q5. Where is the data saved?+
Data is saved in local storage, so it is kept within your browser.
Paid plans allow you to import and export data via CSV.
Q6. Can other users see my highlights?+
No.
Hilightext prioritizes user privacy and does not send highlight content or browsing history to external parties without permission.
Q7. Is it difficult to use?+
Just select the text you want to highlight, right-click, and register it along with a note.
You can also intuitively set color changes and sorting from the options screen.
Q8. Does it support both Japanese and English?+
Yes.
It automatically switches according to your browser's language settings.
Support for other languages is also planned.
Q9. What should I do if I have bugs or questions?+
