About Turan
Built with AI: a Chrome extension that repaints any page with gradient schemes, eye care, dark mode, frosted glass and motion.
Why we built this
It started with a headache
Turan exists because one of us spent eight hours a day reading documentation on a monitor set to 6500 K at full brightness, and went home with a headache most evenings.
The fixes available at the time all had the same problem: they changed the whole page. Invert the colours and photos look like negatives. Drop the brightness and everything goes grey, including the text you are trying to read. Every tool wanted a decision made once, for every site, forever.
What we wanted was smaller and more specific: leave the page alone, warm the light, and let us tune the strength per preset and turn it off per site. Nothing in the store did exactly that, so we built it.
Three things we decided early
The free tier should be genuinely usable. Eleven presets, no time limit, no watermark, no account required. A free tier that exists to be annoying is a marketing decision, and we would rather have people who recommend the extension than people who resent it.
The extension should be able to work with the network off. Not as a fallback — as the normal case. Colour maths happens on your machine. Nothing about your browsing is sent anywhere, because nothing about your browsing needs to be.
Privacy claims have to match the code. It is easy to write "we respect your privacy" on a landing page. It is much harder to keep that true in a licence check, in a per-site override, or in an analytics decision made at 1 a.m. before a launch. Every claim on this site is meant to be checkable against what the software actually does. If you find one that is not, that is a bug and we want the report.
What we are not
We are not trying to be a full accessibility suite. Turan does not replace a screen reader, does not fix contrast for WCAG compliance, and does not claim medical benefits — "reduces eye strain" is a reasonable description of warmer, dimmer light, not a treatment.
We are also not chasing every browser. Chrome and Chromium first. A Firefox port that half-works would damage the thing people actually like about this, which is that it works reliably on the sites they use.
How we work
Small releases, often. Every release is listed in the changelog, including the boring fixes, because a changelog that only lists exciting features tells you nothing about whether the project is maintained.
Feature requests go through the roadmap, where you can vote on them. It is not a democracy — we still have to build the thing — but it is the honest input we have.
Bugs go through feedback and get answered.
The name
Turan is the older spelling of Turán, a Turkic word that has travelled a long way and picked up different meanings in different languages. It felt right for something whose whole job is to change how a familiar thing looks without changing what it is.
Say hello
If you use Turan daily, we would like to know what for. The most useful messages we have received were not bug reports — they were people describing a screen, a room, and a time of day, which is how the eye-care presets got their default intensities in the first place.
