About Turtleglint
A turtle lifts off the reef below you. Sunlight breaks through the surface and slides across its shell in bright, moving lines. You have one breath, a phone in a case, and a few seconds. Whether that picture comes home depends on gear you chose on land: a case that fits your phone, a seal that holds, a shutter you can reach.
Turtleglint helps with the part on land. Turtleglint is a free, AI-written guide to underwater gear for your phone, GoPro, Insta360 or compact camera, with fit and depth linked to the maker's page.
Who it's for
Holiday snorkelers, new freedivers, recreational scuba divers, and beginners stepping up from a pouch to a hard housing or a first compact camera.
The guides are written for beginners, so professional underwater photographers with strobes and interchangeable-lens housings will find little new here. Turtleglint gives no dive training, depth or breath-hold advice. For that, follow your training and the conditions on the day.
How we write
Turtleglint's guides are written by AI. Agent Solo, an AI blogging platform, drafts our articles and publishes them on its own schedule. It works from a brand document we wrote: who our readers are, how we write, the rules below, and a list of makers' published specifications, such as their compatibility pages and depth ratings. Each article's AI notice says it also draws on general product-category knowledge.
Turtleglint publishes without per-article human review: no person reads an article before it goes live. The images in our articles are made by AI too, and our Disclosures page explains how to recognize them.
Five rules for every article
- No testing claims. We haven't tested this gear in the water, so no article may say we tested, handled or used it.
- Fit is the maker's word. An article states fit as the maker's own listing (the maker lists this housing as compatible with these phones) and links the maker's compatibility page. No article may promise that a product fits.
- Depth is the maker's rating. An article gives a depth rating as the maker's figure and links the maker's page.
- Notices on every article. Every article must open with our AI notice, and every article with paid Amazon links must carry our affiliate notice directly above the first one. Our Disclosures page quotes both.
- No paid placements. No brand can pay to appear in an article or to move up a list.
What we check, and when
Because articles go live without review, a slip can get through: a testing claim, a wrong fit list, a missing notice.
Once a week, an automated check reads every published article it has not checked before and alerts the publisher when it finds a rule break. The check cannot confirm that a fit list is right: it only checks that a fit claim links to the maker. At least once a month, the publisher reviews the alerts and any reports readers send. Any flagged or reported article that breaks a rule is corrected or removed.
The weekly check in detail
It alerts the publisher when it finds:
- a testing or first-hand claim;
- a depth figure that differs from our records of the maker's rating, or a color filter described as rated to a depth (makers give filters a working range);
- a fit claim without a link to the maker's page, or a guarantee such as "guaranteed to fit" or "never leaks";
- in the article text, a link to a site outside our approved list, a retailer or Amazon price, or a maker's price without a link to the maker's page and a month and year;
- a missing AI notice, or a missing affiliate notice above an Amazon link in the article text;
- a header image whose alt text lacks the "AI illustration:" label;
- a break of one punctuation rule in our style guide.
It reads each article as our publishing platform provides it, which leaves out the captions of images inside the article and any product cards, so it cannot check those yet.
What to check yourself
We haven't taken any of this gear into the water. Only the maker can confirm that a housing, case or adapter fits your exact phone or camera, and makers change their lists when new phones launch. AI can misread a list, too.
So before you buy, open the maker's compatibility page and find your exact model. Do the same for depth: check the maker's rating and manual before you take anything underwater.
"Tested in water", later
"Tested in water" is a label for products we have taken into the water ourselves, with our own photos and notes on the page. Today, no product on Turtleglint has earned it. Until then, our guides rest on what makers publish.
Report a mistake
Our email address is being set up, and it will be listed on our Contact page. Once it is, tell us the page, the claim, and where you saw something different. A link to the maker's own page is the most useful thing you can send.
We read every report and review them at least once a month, though we may not reply to each one. If a report shows that an article breaks one of our rules, we correct the article or remove it.
