We built a local‑first screenshot app for macOS and would love your feedback

Description and use

Sealshot is a local‑first macOS app that treats screenshots as secure documents, enabling search, annotation, and sensitive‑data protection.

Problem

Screenshots are often treated as disposable files, making them hard to find, reuse, or secure. They can inadvertently contain sensitive data such as emails, API keys, or customer information.

Outcome

Sealshot provides a local‑first, encrypted, searchable, and annotatable screenshot workflow that reduces data loss and protects sensitive information.

Workflow

• Capture region, window, or scrolling screenshot
• Record screen if needed
• Annotate the image
• Run OCR to index content
• Scan for sensitive data and mask it
• Store the image encrypted locally
• Search and retrieve screenshots as needed

Evidence

Treat screenshots more like documents than temporary images.

Source

Everything is processed locally on the Mac.
