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

Kogvio

Freemium

Chrome extension that overlays an AI vision agent on any screen to decode diagrams, math, handwriting, and technical docs without leaving your tab.

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.

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.

Free

Free macOS workspace that unites a terminal, a real Chromium browser, and Claude Code in one hot-reloadable, self-building window.

Self-Building Workspace: ⌘K invokes Claude Code on tterm's own source and hot-reloads the running app so you can extend the tool from inside itself.
Row-Per-Project Layout: Every project gets its own row containing an explorer, a Claude Code session, and a file viewer, so multiple projects stack side by side.
Embedded Real Browser: ⌘B opens a Chromium tab inside tterm that inherits your Chrome cookies, bookmarks, and history — favicons and all.
Diff-Only Review: ⌘G opens a hunk-level diff reviewer for staging and committing changes; there's no editor by design, so you review instead of retype.
Command-Palette Shortcuts: ⌘K palette, ⌘O projects, ⌘P quick open, ⌘⇧F search, ⌘F find, ⌘⇧M for CLAUDE.md, and more make navigation keyboard-first.
Terminal-Respecting Key Handling: Only ⌘-chords are intercepted by tterm; every ⌃-key passes through to the pty untouched, so terminal apps keep working.
Privacy by Default: No account, no telemetry, and no network calls home — the app is a single ad-hoc-signed hobby build.

AI-Paired Coding: Keep Claude Code, your terminal, and docs in one window while pairing with an LLM on a project.
Multi-Project Juggling: Stack several concurrent projects as rows so you can jump between them without alt-tabbing.
Doc-Grounded Development: Use the embedded browser to keep API docs open next to your terminal and diff without leaving the app.
Focused Diff Review: Review and stage AI-generated changes hunk by hunk before committing, rather than editing in place.
Hobbyist macOS Tinkering: Extend the tool itself from inside via Claude Code, treating tterm as a live playground.
