How reports are made

PitchCheck reports are written by software that uses AI models. This page explains what that software does with your deck, where its limits are, and what it never does.

Reading the deck

We take the text from each page of your PDF. Where a page holds its words in an image, such as a screenshot or a chart, we use Amazon Textract to read the image. The text, and pictures of the pages that need them, are then sent to Anthropic’s Claude models through Anthropic’s API.

The Light report

Each dimension is scored from 0 to 4 against the same written questions every time, and each score records the evidence it was read from: not stated, asserted, specific, or backed. Figures are copied off your slides with the words around them, and the sums between them are checked. Your scores are then compared with those of the other decks we have scored the same way to give your percentile.

The Full report

The Full report is written section by section by our review engine. To judge your market and your competitors, it may search the public web, so search queries can include your company name, your product and your market. A separate quality pass then checks the finished report against your deck before it is released to your account.

No person checks a report first

Reports are released as soon as they are produced. We look at a report only if you ask us to, if something has failed, or to check the quality of the service.

What it can get wrong

AI models can misread a slide, miss something that is present, or rely on public information that is incomplete or out of date. The score reflects what is on the page, so a strong business with a thin deck will score as a thin deck. Read a report as a well-informed first opinion, not a verdict, and check anything that matters to you. If you find a mistake, tell us.

What we never do

We do not use your deck to train AI models, and Anthropic does not train its models on content sent through its commercial API. We do not share your deck or report with investors or anyone else, and we do not sell anything about you. Only your scores, without your name, your company or the deck itself, join the pool that percentiles are calculated from.
