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.
nodeterm
Enes Kırca
A node-based terminal manager that puts real terminals and coding agents as draggable nodes on an infinite canvas, with tmux-backed persistent sessions.
Key features
- Everything Is a Node: Right-click the infinite canvas to open a terminal, an AI agent, a sticky note, a Monaco editor, a diff view or a web/video node, then arrange them spatially like a map instead of stacking tabs.
- Persistent tmux Sessions: Every node runs in its own tmux session, so quitting the app or restarting the machine restores each terminal and agent exactly where it left off.
- Hook-Driven Agent Status: Pulsing RUNNING and NEEDS YOU badges come from agent hooks rather than output scraping, with subagent cards showing live transcripts, a per-node context meter, OS notifications and MacBook notch presence.
- In-Node Permission Prompts: Click the notification when an agent blocks, answer the permission prompt directly in the node, and get told the moment the turn completes.
- Kanban View of Live Sessions: Toggle any project between canvas and a Trello-style board with a keyboard shortcut; cards are the running sessions and open into the real terminal with members, due dates, priority and comments.
- Wired Agent Context: Draw an edge between two agent nodes so each can read the other's context on demand, and branch a conversation into a fresh node without losing the original thread.
- Three Surfaces, One Session: Run nodeterm as a macOS/Linux desktop app, as a self-hosted browser app via Server Edition, or from an iOS companion paired by QR code that continues the same live session end-to-end encrypted.
- On-Device Voice Input: Hold a keyboard shortcut to dictate to a terminal using on-device Whisper, review the transcription and send it, with audio never leaving the machine.
Best for
- Parallel Agent Supervision: Run Claude, Codex and Gemini side by side as canvas nodes and see at a glance which one is working and which one is waiting on you.
- Long-Running Session Recovery: Keep multi-hour agent runs and build shells alive across app restarts and machine reboots without rebuilding your terminal layout.
- Multi-Project Context Switching: Give each project its own canvas of grouped terminals, notes and diffs so switching projects restores the whole mental model rather than a tab bar.
- Agent Work Tracking: Manage in-flight agent tasks on a kanban board where each card is a real running session, moving work across columns without interrupting it.
- Remote Development Access: Self-host Server Edition and reach the same live sessions from a browser or the iOS companion when away from the main machine.
- Context Handoff Between Agents: Wire one agent node into another so a research agent's findings feed an implementation agent without copy-pasting transcripts.
