Tekisuto

Tekisuto ("text" in Japanese) is an OCR-powered dictionary lookup tool for language learners. It lets you easily scan text from any app, look up words in your dictionaries, and export them to AnkiDroid for flashcard study.

OCR Backends

Tekisuto offers multiple OCR (Optical Character Recognition) options to suit your needs:

• ML Kit OCR: Fast, on-device recognition powered by Google's ML Kit
• Cloud OCR: Higher accuracy recognition using cloud-based services (requires API key)
• Google Lens: Leverages Google's powerful visual search technology for text recognition
• Tesseract OCR: Open-source OCR engine with excellent multilingual support

For detailed information about the Tesseract OCR backend, see Tesseract OCR Backend.

Features

• OCR Text Extraction: Capture text from any app that doesn't block screenshots
• Dictionary Lookup: Support for Yomitan/Yomichan format dictionaries
• Multiple Profiles: Configure different settings for various languages or learning setups
• App Whitelist: Automatically activate Tekisuto when opening specific apps
• AnkiDroid Integration: Export dictionary matches directly to AnkiDroid as flashcards
• Smart Search Results: Exact matches are prioritized at the top of search results
• Visual Dictionary Management: Dictionary entries show which words have been exported to Anki
• Text Area Selection: Precisely crop the area containing text you want to scan
• Multiple OCR Backends: Choose between ML Kit, Cloud OCR, Google Lens, and Tesseract OCR
• Anki Deck Import: Import words from Anki packages (.apkg files) to track already studied vocabulary
• Privacy-focused: All processing happens on-device with no cloud services required

How It Works

1. Activate the floating OCR button through the accessibility service
2. Capture a screenshot and crop the text area
3. The app performs OCR on the selected area
4. Extracted text is matched against your imported dictionaries
5. Export results to AnkiDroid or save for later reference

For detailed instructions, see the Tekisuto User Guide.
