Keep your secrets safe! Let any LLM read your screenshots and PDFs, vision or not

When you put an image into chat, for many tasks the words are all an agent needs anyway. Cheapshot reads images, PDFs and screen recordings on your Mac, redacts secrets before the text leaves it, and keeps a ledger of the image tokens you saved. The relevant information is sent, the extra image data is not.

Runs on any Mac made after 2019 running macOS 13 or later.

Savings grow with every turn

An image is sent again on every later turn. On a real screenshot, 1,018 image tokens became 37 text tokens.

The ledger counts each image once, so a long conversation saves more than it shows. Over a 50 turn conversation: 50,900 tokens sent as pixels, 1,850 sent as words.

Fast redaction locally, no LLMs!

Upload a screenshot and every key in it is now in a provider’s logs, forever. Cheapshot replaces API keys, tokens, passwords and private hostnames with [AWS_KEY] style labels on your Mac, before any text leaves it.

How redaction works.

Screenshots, PDFs and recordings

PNG, JPEG, WebP, GIF and PDF, plus any video ffmpeg can open. A recording is read only where the screen changed: a 51 minute 4K talk became a 17 screen transcript in 35 seconds on an M4 Pro Mac mini, 31,348 image tokens to 1,133, 96% saved.
