In their own words
Chalkboard
Chalkboard is free, MIT-licensed software that turns a prompt into a narrated explainer video and exports an MP4. It supports 16:9 explainers, vertical short-form reels, and cinematic documentaries. Cinematic mode researches a topic and places cited sources in the script. Productions can be dubbed into multiple languages in one run, with subtitles set independently from narration language. Script generation works with Anthropic, OpenAI, or local Ollama; narration can use Piper, OpenAI, or ElevenLabs. Chalkboard creates hand-drawn diagrams, supports SVG artwork, and can generate images through OpenAI’s gpt-image-2. Subtitles and mood-matched music are enabled by default, with Jamendo or user-supplied tracks available. The project provides a command-line interface, library, HTTP API, and web studio, and runs self-hosted. Ollama and Piper support local generation at zero marginal cost per video. Generated images require an OpenAI API key and may incur costs.
Ghidra
Ghidra is a software reverse engineering framework maintained by the NSA Research Directorate. It analyzes compiled code with tools for disassembly, assembly, decompilation, graphing and scripting, and supports many processor instruction sets and executable formats. The framework can operate interactively or in automated workflows, including work intended to address team and scale needs in complex reverse engineering. Users can write extensions and scripts in Java or Python. Development options include a GhidraDev plugin for Eclipse and support for script editing and module projects in Visual Studio Code. The project describes compiled-code analysis on Windows, macOS and Linux. Installation requires a 64-bit JDK 25 and an official multi-platform release archive. Ghidra is free under the Apache License, Version 2.0, whose terms grant no-charge, royalty-free copyright and patent licenses. The repository warns that some versions have known security vulnerabilities and directs users to security advisories. Its policy directs vulnerability reports to GitHub private vulnerability reporting rather than public issues.
