About PINTRU
The web has nowhere to put what you think. You jot it down somewhere else, you send it to a
friend, you write it under a post nobody will ever connect back to that page — and a month later
nothing is left. PINTRU keeps the thought attached to the thing that caused it.
Open any page: a button appears at the top right. From there you pick one of three things that
only look alike from a distance, and that PINTRU deliberately keeps apart.
━━━ NOTES — your private layer
Reminders, markers, second thoughts, anchored to the exact spot on the page. Only you see them.
You come back to a product page three weeks later and «ask about bulk pricing» is still where you
left it. It is annotating web pages without copying anything into a notes app you will never
reopen.
━━━ REVIEWS — an opinion even where there is no box for one
A product page on a site with no reviews. A newspaper article. The page of a course, a service, a
professional practice. PINTRU puts a review there: public, anchored to the right spot, readable
by anyone who passes by after you.
━━━ FACT-CHECKING — whether what the article claims holds up
Not whether you like the article. Ask for a check and PINTRU does two separate things: a language
model isolates the checkable claims and goes looking for sources; our own code, separately,
measures how the text is built — evaluative adjectives, intensifiers, vague attribution, figures
with no source.
Out comes a score from 0 to 100 with the arithmetic underneath, item by item: how many claims
were corroborated, how many independent sources, which reasoning flaws, how neutral the language
is. You open the sources one by one. If the page changes after the check, the result marks itself
as no longer current.
The wording says what we found, not what is true: «widely corroborated», «partly corroborated»,
«contradicted by sources», «not checkable». That distinction is the whole point, and we do not
hide it.
⚠ The analysis is produced by an artificial intelligence system and every result says so at the
top. It is not an official determination and does not bind the publisher of the page examined.
━━━ EVERY CHECK HAS A PUBLIC ADDRESS
The result does not stay locked inside the extension: it lives on a page anyone can open, read and
share without installing anything. Whoever gets the link sees the score, the arithmetic and the
sources.
━━━ HOW IT WORKS
1. Open any page. A button appears at the top right. Always there, never in the way.
2. Pick the layer: note, review or check.
3. Write and save. The pin stays put and rearranges itself on every screen size.
No sign-up to start: private notes work straight away.
━━━ PRIVACY
To show you the pins of a page, PINTRU sends the address of the open page to our server: it is not
kept in a list of visited pages and not linked to you. Page content is sent only when YOU ask for a
check on that page, and only that once. Private notes stay private. We sell data to nobody.
