GhostWriter by MyHandler vs HOL Guard: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of GhostWriter by MyHandler and HOL Guard — 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.
HOL Guard
HOL
HOL Guard sits between AI coding agents and their tools to intercept risky reads, installs, MCP registrations, and config changes before execution.
Key features
- Pre-execution Interception: Wraps agent launch commands so risky reads, installs, MCP registrations, and config or hook changes are surfaced as a reviewable diff before they run.
- Under 50 ms Local Scan: All scanning happens on-device with no outbound network call, keeping agent workflows fast and usable fully offline.
- One-keystroke Approval Flow: Each block presents the diff on screen so the developer can allow or deny with a single key, and the decision is written to a local receipt.
- Multi-Harness Support: Ships tailored integrations for Claude Code, Codex, Cursor, OpenCode, Gemini CLI, Hermes, and OpenClaw so the same policy engine covers every agent.
- Guard Cloud Sync: Optional cloud tier syncs decision receipts, alerts, and audit history across machines while never uploading file contents, prompts, or environment variables.
- Team Policy Packs: Team plan deploys shared policy packs, team alerts, and investigation routing so multiple developers operate under the same runtime rules.
- Plugin Scanner for Maintainers: Companion CLI and GitHub Action verify plugin manifests, MCP transport posture, and skill-level prompt-injection markers before release.
Best for
- Blocking secret exfiltration: Stop a coding agent from reading .npmrc, .env, or cloud credential files during an automated task.
- Guarding MCP installs: Review new MCP server registrations for insecure HTTP endpoints or wildcard binds before they are added to the harness.
- Enforcing config approvals: Require an explicit allow on config or hook edits proposed by an agent so surprise supply-chain changes are caught in place.
- Team-wide policy control: Roll out a single Guard policy pack across a team so every developer's Cursor or Claude Code session enforces the same runtime rules.
- Cross-device continuity: Sync approval history through Guard Cloud so switching laptops does not force a developer to re-approve safe actions from scratch.
- Plugin release gating: Use the plugin-scanner action in CI to fail PRs that publish plugins below a minimum trust score or with high-severity issues.
