GhostWriter by MyHandler vs Kogvio: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of GhostWriter by MyHandler and Kogvio — 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.

Kogvio
Kogvio
Chrome extension that overlays an AI vision agent on any screen to decode diagrams, math, handwriting, and technical docs without leaving your tab.
Key features
- Highlight-to-Understand Overlay: Draw a box over any part of the screen and get an instant explanation without leaving the active tab.
- Keyboard-only Trigger: Global Cmd/Ctrl + Shift + E shortcut keeps users in flow — no mouse or context switch required.
- Messy Handwriting OCR: Vision engine reads bad handwriting, photographed physical notes, and board formulas that generic OCR misses.
- Native LaTeX Rendering: Complex math equations are rendered inline as LaTeX rather than raw ASCII.
- Color-Coded Code Blocks: Programming snippets keep syntax highlighting when rendered in Kogvio's response panel.
- Contextual Chat: Ask follow-up questions about a specific part of the scanned region (e.g., 'what does node 3 represent here?') without re-uploading.
- No API Key Required: Runs on Kogvio's backend — users don't need their own ChatGPT or Gemini account.
- Cross-Platform via Chromium: Works on Mac, Windows, and Linux through Chrome, Brave, or Edge.
Best for
- Studying Dense Material: Students highlight equations or diagrams in PDFs and lecture slides to get inline explanations.
- Decoding Technical Diagrams: Engineers and architects hover Kogvio over system diagrams to identify components and flow.
- Reading Board Photos: Learners scan photos of whiteboard/blackboard formulas and get a clean LaTeX transcription.
- Understanding Code in Docs: Developers highlight code snippets in technical documentation for quick contextual explanation.
- Rapid Research: Analysts working through equations or notation in academic papers ask follow-ups without leaving the page.
- Handwritten Note Digitisation: Users scan photographed personal notes into readable, formatted content.
