Juggler

Julian Storer

Free

A native desktop workbench for AI coding agents with branching conversation trees, inspectable tool calls and editable context.

Branching Conversation Trees: Fork the session at any point, recursively, so competing approaches and tangents run side by side without polluting the main context.
Miller Column Navigation: A Finder-style column layout lays out tool calls, item properties and nested sub-threads for long reading and editing sessions.
Transaction Inspector: Open any model transaction to see the assembled system prompt, messages, tool definitions, output, token use, timing and stop reason.
The Context Surgeon: Fold history into a new thread, move or copy items between branches, expand a branch back into its parent, and undo structural changes.
Local or Remote Sessions: Run the desktop app locally or the headless binary on the machine holding the code, then attach from the app, a browser or a phone.
Durable Sessions: Sessions are stored on disk as live-synced Yjs documents, so quits, relaunches and dropped connections do not lose the conversation.
Automatic Context Sizing: Juggler measures the full request before each call, reserves room for the answer and compacts older history before limits become an error.
Inspectable MCP Tools: Follow an MCP handoff end to end - schema offered, arguments generated, approval, result and errors - with server status, logs and per-tool filtering.
JavaScript Extension SDK: Context items, LLM loop strategies, slash commands, viewers and Pinboard tabs are extensions you can fork or replace, under a permissive Apache-2.0 SDK.

Exploring Competing Fixes: Branch a thread into two sub-threads to try different approaches to the same bug and compare results before committing.
Auditing Agent Behavior: Inspect exactly what the model received and returned when an agent makes a surprising edit to the codebase.
Remote Development: Run the server on a dev box or GPU machine where the repository lives and drive the same live session from a laptop or browser.
Long Refactors: Keep a multi-hour session alive across quits and reconnects, with the agent paused awaiting approval for its next step.
Provider Comparison: Drive Claude Code, Codex, Copilot, Gemini and local Ollama models through one interface to compare behavior on the same task.
Custom Tooling: Write JavaScript extensions that add slash commands, file viewers or new LLM loop strategies to the workbench.

Free

Free, open-source voice-to-text app for dictation, AI assistant, and voice writing across any app on Windows, macOS, and Linux.

Cross-App Dictation: Press a hotkey (Left Ctrl + Left Super by default) and speak — your words type straight into any app: email, editor, or chat, live as you talk.
Hey Flow Assistant: Say 'Hey Flow' to reply to a message, write an email, or draft a prompt without touching the keyboard; trigger name is renamable.
Live Translation: Speak Spanish, Hindi, French, Japanese, or any language and get clean English typed at your cursor, running fully on-device.
AI Cleanup: Strips 'um's and false starts, fixes grammar, and matches a chosen tone (Professional, Friendly, Concise, or custom) so speech reads polished.
Screen-Aware Answers: One hotkey summons a floating assistant that can look at your screen and answer about the error, chart, or email in front of you.
Private Memory & Profiles: Separate profiles per part of your day; remembers how you like to work locally without sending data off-device.
Cross-Platform Downloads: Ships as a Windows installer, macOS build (one Terminal command on first install), and .deb for Ubuntu and Debian.

Faster Writing: Developers, writers, and support agents dictate at 150+ WPM instead of typing at 45 WPM.
Multilingual Reply: Speak in your native language and reply in polished English without switching keyboards or translators.
Private On-Device Voice Work: Users who don't want their voice sent to a cloud get local dictation and translation.
Voice-Driven Prompts: Draft LLM prompts, emails, or Slack replies by voice inside any editor or chat app.
Screen Q&A: Ask the assistant about the specific error or chart on screen without pasting it in manually.
