Tools

Command-line audio and video downloader supporting thousands of sites: pick formats and quality, grab subtitles and metadata, and merge or transcode with FFmpeg. The actively maintained fork of youtube-dl.

Lets agents model, lay out scenes, tweak materials and run Python in Blender, and import Poly Haven, Sketchfab and AI-generated 3D assets. Requires uv and the companion Blender add-on.

From HKU's Data Intelligence Lab: plugins or skills for Claude Code, Codex and other agents generate agent-callable CLIs for apps like GIMP, Blender and LibreOffice, and the cli-hub package manager finds and installs ready-made community CLIs. Needs Python 3.10+.

MuseScore 4 command-line wrapper from CLI-Anything: lets agents transpose scores, extract parts, add or remove instruments, inspect score info and export PDF, MIDI, MusicXML, MP3 or braille. Handy for music teachers preparing scores in bulk. Needs MuseScore 4 and Python 3.10+.

Engine for math and explainer animations in Python (Community Edition, ManimCE): write scenes and render them to video with the manim command, letting agents create teaching and science animations. On macOS install cairo and pkg-config first; formulas need LaTeX.

Removes image backgrounds with one command: single images, whole folders or watched directories, mask-only output and switchable models like U2Net and SAM. Can also run as an HTTP server or process video frames with FFmpeg. Default models run locally.

Fast speech transcription built on faster-whisper, with word-level timestamps and speaker diarization, suited to meeting notes and subtitles. Diarization needs a Hugging Face token; GPU acceleration needs CUDA.

Industrial-grade open-source speech recognition toolkit from Alibaba's ModelScope, with an agent-friendly funasr command that turns audio into text, JSON or SRT subtitles in one step, with speaker diarization and timestamps. Strong on Chinese. Requires PyTorch.

Command-line tool for bulk-downloading galleries and posts from many image hosts and social platforms, with flexible file naming and config, and yt-dlp integration for video. Main development has moved to Codeberg; the GitHub repo stays in sync.

Converts text to speech with Microsoft Edge's online TTS service and can generate subtitle files at the same time. No API key needed, with voices for many languages. Not an official Microsoft project and depends on that online service staying available.

Pipes live streams from Twitch, YouTube and many other platforms to a local player, or saves them to video files with --output or --record, for keeping and re-editing replays of your own or partners' streams. Viewing needs a player like VLC. Only record content you have rights to.

NetEase's open-source cross-platform UI automation framework: locates elements by image recognition to automate games and apps on Android, iOS and Windows without touching their code. airtest run executes cases and airtest report builds HTML reports.

Removes backgrounds from images and videos with one AI command: batch whole folders, use a portrait model, refine edges or swap in a solid color, and output transparent MOV or composite video onto a new background. Runs locally; install PyTorch and ffmpeg first. Models download on first run.

Offline speech toolkit for Apple Silicon Macs: CLI text-to-speech (including Chinese and voice cloning) and speech-to-text, for voicing lessons and explainer videos or transcribing lectures and interviews, with data staying local. Needs an M-series Mac and Python 3.10+; MP3 export needs ffmpeg.

Create, read and modify xlsx workbooks without Microsoft Excel installed: formulas, formatting and conditional formatting, charts, pivot tables and tables. Runs locally over stdio or as a remote HTTP service.

Lets agents control DaVinci Resolve via its built-in scripting API: edit timelines, organize the media pool, color grade, work with Fusion and render. Requires DaVinci Resolve Studio; the free version works only up to 21.0.x through the in-app scripting bridge.

Music source separation CLI that splits songs into vocals, drums, bass and other stems; --two-stems extracts just vocals and can output MP3. The official version maintained by the original author after leaving Meta; no new features are planned.

Works with Gmail, Calendar, Drive, Docs, Sheets, Slides, Tasks, Chat and other Google Workspace services, with multi-user OAuth and read-only mode. You create your own Google OAuth client and run it in HTTP mode.

Connects agents to Ableton Live for music production: create MIDI and audio tracks, write notes, load instruments and effects, arrange whole songs and control playback. Requires installing the companion Remote Script in Live; anonymous telemetry is on by default.

Runs open image models like FLUX, Qwen Image and Z-Image locally on a Mac: text-to-image, reference-based edits, inpainting and upscaling, all on-device. Needs Apple Silicon and uv; the first run downloads models and is slow. Check each model's license before commercial use.

Connects Google Search Console so agents can analyze queries, clicks and rankings, compare periods, check URL indexing status and manage sitemaps. Not an official Google project; you need your own Google Cloud OAuth credentials or a service account.

Uses Telethon to operate Telegram as your personal account: search, send and receive messages, schedule sends, and manage contacts, groups and channels across 80+ tools, with an optional read-only mode. Needs a Telegram API ID and runs locally as a service.

Local transcription that's compatible with the OpenAI Whisper CLI but faster and lighter: outputs SRT/VTT subtitles or text and can transcribe a live microphone. Needs Python; models download on first run; speaker labels need pyannote.audio and a Hugging Face token.

Lets agents query Google Ads accounts, campaigns and performance data with GAQL; currently read-only tools only. Maintained by Google; needs Google Cloud credentials and Google Ads API access.
