Ask any of 10 AI providers, or a local model. Hand it to your coding agent: Claude Code edits the canvas you have open, live, over MCP. Or pull it from a GitHub repo, every arrow citing its file and line. The CLI checks drift in CI, so diagrams keep up with your code.

Most AI tools can read your files. The Drive AI does the work after reading. One agent across Google Drive, SharePoint, OneDrive, Dropbox, your computer and your NAS. It organizes thousands of files in one prompt, finds duplicates, builds new documents like a closing binder from 20 PDFs, and runs routines on autopilot as new files arrive. It shows the plan first, waits for your OK, and every change can be undone.

Most social APIs let an agent publish text or media it already has. PostNitro lets it design the post too. Connect from Claude or ChatGPT in one click (OAuth, no API key), or use our 35-tool MCP server, CLI or REST API. Your agent turns a topic, article or X thread into an on-brand carousel, image post or animated video, then schedules it to LinkedIn, Instagram, TikTok, Threads, Facebook and Pinterest. Or it hands you an editable draft to finish.

CLI Manager now has an AI Control API. Claude Code, Codex or any script can open sessions in CLI Manager, send prompts, wait, and read the screen - in terminals you can watch.

Plus everything from launch #1: Claude Code, Codex and Gemini CLI in one sidebar. Free, MIT open source, macOS.
