Chalkboard vs JEB

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.

JEB is a reverse-engineering platform for disassembly, decompilation, debugging, and analysis of code and document files. Its Android tools support static and dynamic app analysis, including multi-dex decompilation, resource reconstruction, and debugging of Dalvik and native code. Other modules address Intel x86 and x86-64, ARM, MIPS, RISC-V, WebAssembly, Ethereum contracts, Siemens S7 PLC programs, and PDF documents. Python or Java scripts and plugins can automate analysis, including through headless front ends. The GUI runs on Windows, Linux, and macOS for x64 and arm64 systems and requires JDK 21 or above. JEB Community Edition is free and described as suitable for researchers, students, hobbyists, and nonprofit reverse engineers; its listed plan covers x86 and x86-64 decompilation. The separate demo restricts decompilation, disables project saving and loading and clipboard use, limits session time, and requires an internet connection. Paid plans include Android modules from $140 per user per month and JEB Pro from $2,000 per user per year. PNF Software was founded in 2013 and is based in Silicon Valley, California.
