Pintru is a web layer. Pins you can leave on any page, article or product on the web. To note down what you think, to have your say, or to find out whether what you’re reading is true.
Jottings, reminders, bookmarks. Visible only to you, until you decide to share them.
It’s your memory on the web: come back to a page and find exactly what you were thinking, right where you thought it.
Opinions anchored to the right spot, right where they’re needed.
Review things even where you never could before.
Can what you’re reading be checked? An AI language model measures how the text is built, isolates the claims and goes looking for sources.
The result is a score from 0 to 10 with sources you can open, a neutrality index worked out item by item, and readers’ opinions kept separate from the machine’s. If the page changes after the check, the result marks itself as out of date.
Nothing to set up. Nothing to learn. Open any page and put your pin wherever you like. You’ll always find it there.
Great fabric, but the left strap came unstitched after three trips. The seller replied the same day.— sample text, not a real review
With PINTRU you can have your say in every place, on every page, about every product on the web.
Does it have a web address? Then you can leave a Review Pin! “Stick” your opinion on the item, the place or the page it’s about.
Sites where you couldn’t have your say before.
Leave your mark on the web, with Pins wherever you want them. The page of a service, a course, a professional practice, or a product page that didn’t accept reviews.
No era has needed the truth as badly as this one, or found it so hard to recognise. Information is everywhere, fragmented, intrusive. The way it reaches us has changed: no longer from the few to the many, but from many to many. Anyone can publish, and nobody vouches for it.
Disinformation doesn’t only fool the vulnerable and the unprepared. Hoaxes play on a prejudice, a dislike, a fear — something we care about, or don’t know well enough to understand.
We don’t hand you the truth. We try to give you a broader view in one click (or one Pin): a language model isolates the claims that can be checked and looks for sources; code measures how the text is written, using objective criteria, to form an assessment. You can read the sources, add to them, and contribute to the fact-check by giving your own opinion.
Illustrative example — made-up text and figures to show what a result looks like
The uses people come up with on their own are often the most interesting. Here are a few:
Numbered pins along a page: a step-by-step path anchored to real content. Product demos, portfolios, onboarding.
Note sources, collect quotes, mark where you found that figure — and find it again in the right place.
Precise comments on a page under construction, like notes on a draft. Web design, QA, team reviews.
The rating sits on the product page, not on a separate review site: see what others think while you’re making up your mind.
Rate the tutorial, the recipe, the tool — each on its own page, with the rating tied to the right subject.
A group of knowledgeable people leaving opinions where they count, and making them available to everyone.
Advertising claims, statistics out of context, product statements: put to the test on the page that makes them, not somewhere else.
The other side of the story, added where it’s only half told, visible to whoever comes after you.
A look at how an article is written — vague attributions, data with no source — before passing it on to someone else.
PINTRU works across the whole web thanks to a small app, called an extension, that you add to your browser.
Install it once and your pins follow you to any page on the web.
Choose your browser: next to it you’ll find the package and the steps to install it.
Do you have a website and want to turn PINTRU on for your visitors, so they can leave reviews, notes and fact-checks? Paste the code below and PINTRU will be available to everyone.
A single line, in the template shared by your pages, just before the closing </body>.
It respects your visitors’ cookie choices. PINTRU only starts after the visitor has accepted your site’s cookies: until then it loads nothing and doesn’t contact our servers. If they change their mind, it switches off.
In the template shared by your pages (theme footer, main layout), before </body>. Once is enough: it applies to every page that uses it. Don’t load embed.js directly and don’t change the code: it decides when to start.
window.pintruStart(); if they withdraw consent, window.pintruStop().window.PINTRU = { consent: true } before the code.On sign-in, sign-up, cart and checkout pages, and on pages with password or card fields, PINTRU doesn’t start on its own. To switch it off on another page, set window.PINTRU = { enabled: false } before the code.
Visitors who already have the extension see PINTRU only once: the extension takes priority and your site’s code steps aside.
If your site has one, allow https://app.pintru.com in script-src, connect-src, frame-src and img-src.
By including the code you accept the terms for sites that include PINTRU.
Start free with notes. When you want to review and fact-check, choose Premium or Extra.
Put notes on the pages you visit.
For people who want to have their say with reviews and check the news.
For people who don’t want to miss a thing and need to check sources thoroughly.
New subscriptions are paused at the moment. The plans above are the real ones, but you can’t subscribe to one until we reopen. If you already subscribe, there’s nothing to do: your plan stays active and renews.
No. When you create your account in the same browser, the notes you wrote as a guest move to your account, and from then on you’ll find them on every device. Without an account they stay tied to that browser: if you clear your browsing data or switch computers, you can’t get them back.
On sign-in, sign-up, cart and checkout pages, and on pages with password or card fields, PINTRU switches itself off so it doesn’t sit next to your sensitive data. It doesn’t appear on PINTRU’s own pages either. If a site has PINTRU built in, you’ll only see the P after accepting that site’s cookies.
No. When the extension is there, the version built into the site steps aside and you see a single P, with your account.
A fact-check only makes sense on continuous text. It can’t be requested on lists of links, product pages, service pages, very short texts or paywalled articles where only the beginning is visible: judging a fragment would be misleading. If the page has the text but PINTRU can’t read it on its own, you can select the headline and paragraphs to check yourself.
First you need to confirm your email address, using the link we sent you. It’s only needed for fact-checks: notes and reviews work straight away.
Every month, on the same day you activated your plan. The exact date is in your personal area, under Usage. The 3 trial fact-checks on the free plan, however, don’t renew.
Anyone who opens that page, with no account and no subscription. A fact-check, once done, counts for everyone who visits: you pay to request a new one, not to read it.
No one on their own. The measurements of how the text is written — vague attributions, data with no source, emphasis — are calculated by code, with declared weights and repeatable results. A language model isolates the claims that can be checked and looks for sources, which stay visible so you can open them. Readers’ opinions sit in a separate panel, because that’s something else again.
The fact-check covers the text as it was when it was done, and shows the date. If the text changes substantially, the fact-check pin flags it and a new one can be requested.
Reviews and public notes go through an automatic check before they appear. If something is held back, you’ll see it marked “awaiting moderation” until it’s approved. The receipt you can attach is seen only by moderators and is never published.
PINTRU ignores tracking parameters in web addresses, such as campaign tags: the same article shared through different links stays a single page. Versions that really are different pages, such as a version in another language or another product’s page, stay separate.
Your plan stays active until the end of the period you’ve paid for. After that, everything stays: your notes, private and public, and the reviews already published. If you have more notes than the free plan allows, you can’t add new ones until you’re back under the limit. On the free plan you can’t write new reviews.
Not with an account: your notes, reviews and fact-checks are saved to your account, and you’ll find them again if you reinstall or use another browser. As a guest, however, you lose the link to the notes you had written.
Note it, Comment, Check it.
