Tool
Gemini API Image Bounding Box Visualization
— Analyze images using the Google Gemini API and visualize detected objects as bounding boxes or points overlaid on the original image with coordinate grid lines. The tool supports multiple Gemini model versions and can extract either bounding box coordinates in normalized format or point locations with labels, displaying the results alongside a detailed visualization canvas. Store your API key locally for convenient access across multiple sessions.
Tool
TIFF Orientation Reader
— Read TIFF orientation metadata from JPEG images by uploading or dragging files into the drop zone. The tool parses the EXIF data embedded in the image file to extract the orientation tag, which indicates how the image should be displayed (normal, rotated 90° clockwise, rotated 180°, or rotated 270° clockwise). Debug information shows the file analysis process, including EXIF location, endianness detection, and TIFF header validation.
Tool
Audio Spectrum Visualizer
— Visualize real-time audio frequency data from your microphone as an animated spectrum display. This application uses the Web Audio API to capture microphone input, analyze frequencies using FFT (Fast Fourier Transform), and render dynamic bars that respond to sound levels across the frequency spectrum. Grant microphone permissions when prompted to begin the visualization.
Tool
Image resize, crop, and quality comparison
— Compare images at different sizes and quality levels by uploading a photo, defining a crop area, and generating multiple preview versions with varying dimensions and compression settings. The tool displays file sizes for each variant and allows interactive toggling between normal and full-width viewing modes, as well as direct downloads. Transparency detection automatically reveals a background color picker when needed for images with alpha channels.
Tool
EXIF Data Viewer
— View EXIF metadata and GPS coordinates from uploaded images using this tool. Upload or drag-and-drop an image file to instantly display all embedded EXIF data, including GPS latitude and longitude with a link to Google Maps if available. The tool supports common image formats such as JPEG, PNG, and HEIC.
Tool
Box shadow CSS generator
— Generate custom CSS box-shadow effects with interactive controls and real-time preview. Adjust horizontal and vertical offsets, blur radius, spread radius, color, and opacity using intuitive sliders and color picker to visualize shadow changes instantly. Copy the generated CSS code directly to your clipboard for immediate use in your stylesheets.
Tool
Timezone Meeting Planner
— Plan meetings across multiple time zones by selecting two locations and viewing their local times side-by-side. The comparison table displays 48 consecutive hours of UTC times with corresponding local times for each timezone, making it easy to identify overlapping working hours. Your timezone selections are automatically saved in the URL for convenient sharing and bookmarking.
Tool
Chrome LanguageModel Playground
— Interact with Chrome's built-in language model API through this web-based playground interface. The application allows users to check model availability, download the model if needed, and execute text prompts to generate responses directly in the browser. A persistent history feature maintains records of previous prompts and responses for easy reference.
Tool
Compare PDFs
— Compare two PDF documents side-by-side to identify differences between them. Upload or drag and drop two PDF files to view their pages rendered as images, with a third panel highlighting any pixel-level differences in red. This tool is useful for detecting changes between document versions, comparing drafts, or verifying document modifications.
Tool
Language Model Elo Ratings
— Compare Elo ratings across different language models and dates using this interactive animated bar chart. Load your own JSON data with model names, dates, and Elo scores, then watch the rankings evolve over time with customizable animation speed. The visualization displays the top 20 models at each time point, making it easy to track performance trends and competitive dynamics in the AI landscape.
Tool
CSV marker map - use ?csv=URL to CSV to populate
— View CSV data as markers on an interactive map using the `?csv=URL` parameter to specify a CSV file containing latitude and longitude columns. The map supports additional customization through query parameters including `center` to set the initial location, `zoom` for zoom level, `color` to change marker color, and `marker` to add individual points. Map position and zoom level are automatically saved to the URL bar as you navigate, allowing you to share your current view with others.
