Is there a free TextSniper alternative for Mac?

Yes. Apple Live Text is free and built in. ocrogram is a free, MIT-licensed Homebrew tool that OCRs every screenshot automatically with Apple Vision. It does not replace TextSniper's region hotkey — it replaces the repeat copy-from-screenshot workflow.

Does ocrogram work like TextSniper?

No. TextSniper is a hotkey you press to select a region. ocrogram watches the screenshot folder and copies text after you take a normal macOS screenshot. Different habit, same Vision engine.

Does ocrogram upload screenshots?

No. Recognition runs on-device via Apple Vision. The image and the text stay on your Mac.

Free TextSniper alternatives for Mac

Compare TextSniper, Live Text, and ocrogram — a free, open-source tool that OCRs every screenshot automatically.

TextSniper is a paid Mac app: press a hotkey, drag a rectangle, get text. It is good at that job. It is not the only way to get there, and it is not free.

What you are actually buying

Most paid Mac OCR apps sell a capture overlay. The OCR underneath is usually Apple Vision, the same API Preview and Live Text already use. You pay for the overlay, the menu bar icon, and the habit.

Free options

Apple Live Text

Built in since Monterey. Open an image, drag the words, copy. Zero install. Every capture is still a manual selection. Details: Live Text limitations.

Preview → Copy Text

Open the screenshot, Tools → Copy Text. Fine for one image. Not a workflow.

ocrogram

Free, MIT, open source. You keep taking the screenshots you already take. A background LaunchAgent OCRs each new file and puts the text on the clipboard. No overlay, no extra hotkey, no account.

Honest comparison

Hotkey, drag a region, no file on disk: TextSniper (paid) or similar overlay apps. ocrogram will not do this.
You already screenshot with Cmd+Shift+4: ocrogram. The file is the trigger.
One image, once: Live Text. Do not install anything.
Script or pipeline: ocrogram-helper from the terminal, or Tesseract if you need Linux too.

If your muscle memory is "press a dedicated OCR hotkey," stay with TextSniper. If your muscle memory is "screenshot, then wish the text was already on the clipboard," install ocrogram.
