Markup Hero vs ScreenAI

Markup Hero creates annotated markups from screenshots, uploaded or pasted images and PDFs, blank canvases, or captures made with its Chrome extension. It runs on Mac, Windows, and Chrome, with scrolling capture, annotation tools, OCR, and cloud sharing. Markups can be exported as JPG, PNG, or PDF. The free Hero plan includes all product features, up to 25 markups, and 24 hours of editing for each free-plan markup. An account is required after five markups; the stated reasons are linking files to users and providing customer support. Super Hero offers unlimited markups, editing, and saving. Premium Monthly is $5 a month, while Premium Annual is $3 a month billed annually; those listings include unlimited markups and permanent editing history. Super Hero Monthly is $5 a month, and Super Hero Annual is $3 a month billed annually. Team and lifetime plans are also listed, with no prices specified.

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.
