Editorial standards

Intellect Plus publishes short knowledge stories ("cards"), each with a longer explanation and its sources. This page explains where they come from, how they're checked and how we put mistakes right. Intellect Plus is published by Vaitly Limited in the United Kingdom.

Sources

• Every card is written from public and openly licensed sources, such as encyclopaedias, museum and library collections, open-access research and official statistics.
• Each card names its source, shows the source's licence and links to the original, so you can check it yourself. A card's page lists its sources under "Sources".
• A source is used only if its licence allows it. Share-alike material keeps its licence and is marked as adapted.

How cards are prepared

• Cards are prepared partly with automated tools, including artificial intelligence, working from the sources named on the card.
• Before a card is published it passes automated checks: the source's licence, our content rules (for example, no nudity, no religious or political advocacy, nothing unsuitable for a general audience) and checks on the writing.
• Cards that are found weak or wrong are rewritten from their sources or withdrawn.
• These checks are automated. Cards are not individually reviewed by a person or a subject expert before publication.
• A card's page shows when it was published and, if its text has changed since, when it was last updated.

Pictures and videos

• Pictures are credited on the card. Pictures credited "Intellect (generated)" were made by us with an AI image model to illustrate the story; they are not photographs of real events.
• Video cards play talks and explainers from hand-picked educational channels in the channel's own player, with a card of the facts behind them. The channel is named on the card.

Intellect Uncovered answers

• Each answer on Intellect Uncovered is prepared with automated tools, including artificial intelligence. Its claims are checked by automated tools against the sources it names, and every source is listed with its publisher and the date we read it.
• "What the evidence shows" is what the sources say. "Our take" is our own interpretation and is labelled as that. Where the evidence is disputed or thin, the answer says so.
• We don't publish personal medical advice, diagnoses, treatments or dosing on these pages.
• Photographs are credited with their licence. A picture made with artificial intelligence is labelled as an illustration and is never offered as evidence.

Correction notice: 2 November 2026

An outside review found a card about web colours filed under Health with an unrelated leukaemia paper as further reading. When we looked, it was not a one-off.

• What went wrong: topics grew by following links between encyclopaedia articles, and each new article was filed in the section of the article that linked to it, so some drifted far from their section. Further reading came from keyword searches, and a matching word was treated as proof of relevance.
• Done so far: we withdrew the web-colours card and its video version. We ran all 58,491 further-reading links on live cards through a new automated relevance rule and removed the 19,021 that failed, from 13,348 cards.
• Filing, updated 3 November 2026: an automated check found Health cards on subjects that were not health. We moved 565 of them to the right topic where a second automated check agreed, and left 12 where it did not, pending review. Cards from our automated queue must now pass a filing check before they publish.
• Not finished: the Health check is still running, so misfiled cards remain live. Other topics have not had it, and older cards in them may be misfiled too. The filing checks use one model, so they can be wrong, and they do not test accuracy. The further-reading rule looks at titles only, so links it passed may still be weak, and it does not test whether a source supports a card's claims.

Corrections

• Every card has a flag for reporting incorrect or inappropriate information, in the app and on the web. You can also report a problem with a card or email [email protected] with the card's link and what is wrong.
• We check the card against its sources and act within 5 working days. We correct or remove a card that is inaccurate (see corrections and complaints in our terms).
• A report never changes or removes a card on its own: a person at Intellect Plus decides.

What our cards are not

• Cards are general knowledge, not professional advice. They don't replace a doctor, lawyer or financial adviser.
• Mentions of companies, people, products and brands are not endorsements.
• Brain challenges are puzzles with every answer explained. Intellect IQ reflects your performance on Intellect Plus's challenges; it isn't a clinical or standardised IQ test, and we make no claim that using the app changes intelligence or health.
• Sponsored content, where it appears, is labelled "Sponsored" and is never part of a card's text.

Citing a card

Link to the card's own page (https://intellectplus.co.uk/app/<card>), name "Intellect Plus", and please credit the card's original sources too.

Search engines and AI answer services are welcome to read our public pages and quote a card briefly with a link back to it. OpenAI's GPTBot, Anthropic's ClaudeBot and Google-Extended may also use them to train models; bulk copying or republishing by anyone else is not allowed (terms).
