GhostWriter by MyHandler vs OpenCode Superapp: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of GhostWriter by MyHandler and OpenCode Superapp — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
GhostWriter by MyHandler
MyHandler.ai
Windows writing assistant that reads the screen around your cursor on a hotkey double-tap and types a context-aware draft in your voice.
Key features
- Hotkey Double-Tap Drafting: No prompt or dictation is needed — a double-tap with the cursor in any text field triggers capture and drafting directly in place.
- Screen Context Capture: Reads the thread, form or partial sentence surrounding the cursor locally on the machine, using that on-screen context as the entire input.
- Writing Intent Classification: Determines whether the moment calls for a reply, a continuation, a filled-in answer or a fresh compose before writing a single word.
- Sender and Identity Mapping: Maps each message in a thread to its sender and works out which handle is the user's, so the draft answers the other party rather than the user's own words.
- Calendar Cross-Check: When a draft proposes a time, it is validated against the next two weeks of a connected calendar before the text appears.
- Selection Rewriting: Selecting existing text before the hotkey rewrites that selection instead of composing something new.
- Nothing Sent Automatically: The generated text appears at the cursor for the user to read, edit or delete; sending always remains a manual step.
- Local Vault with Zero-Retention Cloud: Capture runs against an encrypted vault on the user's own PC and the assembled context is processed by a zero-data-retention cloud model.
Best for
- Email Backlog: Clearing a queue of owed replies by drafting each one from the thread already on screen instead of retyping the same answer.
- Chat and Slack Replies: Answering a message in a team chat where the draft is grounded in who asked whom for what in the visible thread.
- Web Form Completion: Filling a blank answer box under a question on a web form or application without switching to a separate chat window.
- Sentence Continuation: Picking up a half-written paragraph exactly where it stops, without the assistant restating what was already typed.
- Meeting Scheduling Replies: Responding to a request for a time with a proposal that has already been checked against the user's calendar.
- Tone-Sensitive Rewrites: Selecting a blunt or rough draft and having it rewritten in the user's own voice before sending.
OpenCode Superapp
MedHue Labs
OpenCode Superapp is a native, local-first Mac workspace that gives the OpenCode runtime browser, computer-use, voice, and extensible widgets.
Key features
- Any OpenCode Provider: Use every model and provider OpenCode supports with your own credentials and billing, from OpenAI and Anthropic to xAI and Ollama.
- Integrated Local Ollama: Install the app-managed Ollama engine and discover models already stored in your local library over a private loopback endpoint.
- Native Desktop Workflows: Projects, parallel sessions, Files, Git, worktrees, terminals, search, and configuration stay in one workspace instead of scattered tools.
- In-app Browser Automation: A Superpower that lets OpenCode inspect and operate the exact web experience in an embedded Browser under permission-gated actions.
- Guarded Native Computer Use: A Superpower that operates native macOS applications through guarded tools with consequential actions kept visible.
- Supe Realtime Voice + Local Dictation: Speak to Supe to create, message, monitor, and open OpenCode tasks, or compose prompts with private multilingual dictation.
- Extensible with Widgets, Skills, and MCP: Add commands, right-panel apps, Skills, MCP services, and local packages, or ask the agent to build, preview, and publish Home widgets with isolated storage.
Best for
- Private local coding: Route sessions to on-device Qwen or other Ollama models when working on sensitive code that cannot leave the Mac.
- Voice-driven task control: Use Supe Realtime Voice to open, monitor, and message OpenCode tasks hands-free while multitasking.
- Web-flow automation: Have OpenCode inspect and drive the in-app Browser to complete a real web task and hand the result back into the workspace.
- Native app manipulation: Grant Computer Use to a workflow that needs to move files, click through a macOS app, or coordinate two desktop tools.
- Remote control from mobile: Continue a real OpenCode session from a paired phone or browser via the encrypted relay while the Mac stays home.
- Custom project dashboards: Ask the agent to draft a Home widget for ship status or test counts, preview it live, and publish once it feels right.
- MCP-connected knowledge: Attach MCP services and local resource packages so the workspace pulls in project context instead of re-crawling every session.
