eSearch

esearch is a Lightweight, privacy-conscious utility designed to accelerate knowledge work by collapsing multiple manual steps — screenshotting, copying text, pasting into search engines or translators — into a single, keyboard-triggered ACTion. It targets users who regularly extract, underStand, and act on visual Information from screens: researchers reviewing PDFs or slIDEs, developers debugging UIs, students annotating lecture materials, or bilingual Professionals scanning foreign-language interfaces. Unlike cloud-dependent screen readers or Enterprise RPA tools, eSearch prioritizes local processing where possible and transparent API routing for optional services like translation.

What it does

eSearch operates as an Intelligent capture layer between your screen and the web. With a configurable hotkey, you select any region of your display. The APP then applies OCR to convert visible text into editable characters, optionally sends that text to a search engine (e.g., Google or Bing), passes it through a translation API (supporting Chinese, English, Japanese, Korean, Russian, and more), or uploads the screenshot directly to perfORM reverse image search. It also includes bASIc screen recording with export to MP4 or WebM.

Key capabilities

• Multi-engine OCR: Integrates Tesseract and other open-source OCR backends, enabling high-accuracy text reCognition across fonts, layouts, and mixed-language screenshots.
• one-click search & translation: Launches browser searches using extracted text or routes queries through configurable translation APIs (e.g., DeepL, LibreTranslate, or custom endpoints).
• Reverse image search: Uploads cropped screenshots to major search engines to find visually similar images, source pages, or licensing detAIls.
• Customizable Workflow: Users DeFine default OCR engines, translation targets, search domains, and hotkeys — no coding required.
• cross-platform availability: Runs natively on Windows and macOS via desktop builds, and offers a functional web veRSIon for quick access without installation.

Who it is for

eSearch serves independent knowledge workers, educators, developers, and language learners who value speed, control, and transparency. It’s especially useful when working with non-copyable content (e.g., scanned documents, protected web pages, or Embedded UI text) or when rapid multilingual comprehension is needed without switching between five different apps.

How to get started

Download the latest desktop release from the official site or run the web version directly. After launch, configure preferred OCR and translation backends in settings — most options work out-of-the-box with free-tier APIs. Trigger a screenshot with the default hotkey (Alt+Q), draw a selection, and choose an action: copy text, search, translate, or reverse-search the image. No account or sign-in is required.

Pricing and access caveat

eSearch is fully Open Source and Free to use. Some optional translation or search features may rely on third-party APIs that require user-provided keys or have usage liMITs — these are clearly flagged during setup. While the core OCR and local processing are offline-capable, full functionality (especially translation and image search) depends on internet connectivity. Version numbers, developer attribution, and exact system requirements may vary across builds and are not explicitly documented in public sources.
