A side-by-side comparison of Juggler and Tucky — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.

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.

coconutStudio

Freemium

A native Mac notes app that docks as a thin stripe on the screen edge, with an encrypted local store and a built-in AI agent.

Edge-Docked Notes: Notes rest as a thin stripe at the screen edge and fan out into readable titles when you reach over, so they never occupy a window until you want them.
Voice Agent from Any App: Holding Option-Space brings a bar to whatever application is in front and lets you talk to your notes, with dictation in over 60 languages.
Ask About This Note: Option-J asks a question about the open note; the title travels with the question and the body is only read after you grant permission.
Bundled Frontier Models: The reasoning models needed for writing, editing and cross-note search ship inside the app, so there are no API keys to configure.
Local Encrypted Storage: Notes are local-only files encrypted on disk and stay on the Mac, with the app clearly scoped to a single machine.
App Connectors: Gmail, Google Calendar, Docs, Sheets, GitHub and Notion can be linked so the agent answers using your calendar and mail alongside your notes.
Note Essentials: Checkbox tasks, live Markdown rendering, global shortcuts, clean exports and self-updating builds in a roughly 15 MB app.

Capturing Notes Mid-Task: Jotting a thought without leaving the current app because the notes are already docked at the screen edge.
Hands-Free Dictation: Speaking a note or a question while working in another application, using the global voice shortcut in any of 60+ languages.
Asking Across Your Notes: Searching and reasoning over an accumulated set of notes without moving them into a cloud service.
Privacy-Sensitive Note Keeping: Keeping journals, client details or personal records in an encrypted local-only file rather than a synced service.
Meeting Prep with Context: Pulling calendar entries and mail through the connectors so the agent can draft or summarize against real appointments.
Lightweight Task Tracking: Using checkbox tasks and live Markdown for daily to-dos in the same place the notes already live.
