ScreenAI vs ShareX

ScreenAI brings screen capture, annotation, and AI questions about captured content into one desktop workflow. It runs on Linux, macOS, and Windows, and can capture regions, full screens, windows, freeform selections, or scrolling content. Timed delay and a precision magnifier are available during capture. Annotation tools include drawing, arrows, shapes, text, step numbering, highlighting, blur, crop, and eraser. ScreenAI extracts text from captures and can mask emails, numbers, and IP addresses. AI options include Claude, GPT-4o, Gemini, Mistral, Grok, and Ollama, with model switching, Best Answer mode, web search, and persistent memory. Captures are saved and OCR-indexed automatically; users can chain, batch process, pin, or send them to AI together. Exports include PNG, JPEG, PDF, and animated GIF. The site describes the app as open source under AGPL and says data stays between the user and their AI, without a middleman server or telemetry. The free plan allows 10 AI requests per day; Premium costs $7 a month and includes unlimited requests.

ShareX is a free, open-source screenshot and screen-recording tool for Windows. It captures the full screen, a selected region, the active window, a scrolling page, or a monitor, and can record video and GIFs. Its image editor provides annotation and redaction tools, while OCR recognizes text in images. After a capture, ShareX can copy, open, shorten, or share links, and supports many upload destinations as well as custom uploaders. It also lists browser extension support and supports many languages, including English, Hindi, and Spanish. ShareX requires no account and has no advertisements. The ShareX Team maintains the software, which has had more than 18 years of active development and over 33 million downloads worldwide. The maker describes its approach as privacy first. The website provides documentation guides and links to related GitHub projects. ShareX is available for Windows.
