    Showkase

    Annotation-processor based Android library

    Showkase is an Android library developed by Airbnb that helps teams organize, visualize, and manage their Jetpack Compose UI components through an automatically generated component browser. It uses annotation processing to scan the codebase and build a structured interface where developers can explore all composables, colors, and typography in one place. This significantly improves discoverability and reuse of UI elements, which is often a major challenge in large codebases with hundreds of components. Showkase also renders components under different conditions such as dark mode, right-to-left layouts, and scaled fonts, allowing developers to identify issues early in the development process. ...

    Segment Anything

    Segment Anything

    Provides code for running inference with the SegmentAnything Model

    ...The architecture separates a powerful image encoder from a lightweight mask decoder, so the heavy vision work can be computed once and the interactive part stays fast. A bundled automatic mask generator can sweep an image and propose many object masks, which is useful for dataset bootstrapping or bulk annotation. The repository includes ready-to-use weights, Python APIs, and example notebooks demonstrating both interactive and automatic modes. Because SAM was trained with an extremely large and diverse mask dataset, it tends to generalize well to new domains, making it a practical starting point for research and production annotation tools.

    Training data (data labeling, annotation, workflow) for all data types

    ...This is aimed to reduce your data labeling bills and increase your Training Data Quality. Training Data is the art of supervising machines through data. This includes the activities of annotation, which produces structured data; ready to be consumed by a machine learning model. Annotation is required because raw media is considered to be unstructured and not usable without it. That’s why training data is required for many modern machine learning use cases including computer vision, natural language processing and speech recognition.

    Argilla

    Argilla

    The open-source data curation platform for LLMs

    ...Argilla is free, open-source, and 100% compatible with major NLP libraries (Hugging Face transformers, spaCy, Stanford Stanza, Flair, etc.). In fact, you can use and combine your preferred libraries without implementing any specific interface. Most annotation tools treat data collection as a one-off activity at the beginning of each project. In real-world projects, data collection is a key activity of the iterative process of ML model development. Once a model goes into production, you want to monitor and analyze its predictions, and collect more data to improve your model over time. ...

    KSP

    KSP

    Kotlin Symbol Processing API

    KSP is Kotlin’s lightweight, idiomatic alternative to Java annotation processing that gives compile-time access to Kotlin program structure. Rather than forcing Kotlin through Java’s annotation APIs, it exposes Kotlin-first symbols—classes, functions, properties, types—so processors can generate code efficiently. The design dramatically reduces incremental build overhead by operating directly on symbols without compiling stubs, which speeds up large multi-module projects. ...
