Nic Hyper Flow

A VS Code extension that runs AI agents directly in your editor. The agent can read and edit files, run commands, search the web, manage terminals, and more — all from a chat interface inside the sidebar.

Available on the VS Code Marketplace · $18 USD/month


What it does

Model Support

The extension connects directly to major AI providers. You bring your own API keys:

  • OpenAI — GPT-4o, GPT-4.1, o3, o4-mini (with configurable reasoning effort: low / medium / high / xhigh)
  • Anthropic — Claude Sonnet, Claude Opus
  • Google — Gemini 2.0 Flash, Gemini 2.5 Pro
  • DeepSeek — DeepSeek V3, DeepSeek R1

Model and reasoning effort are selectable from the composer UI.


Tools (60+)

File operations: read, write, delete, copy, move, rename, patch (unified diff), list directory recursively

Code: format, replace text, parse lint errors

Terminal: start/stop shell sessions, send input, read output — full interactive terminal control

Web: search (Brave + Wikipedia fallback), read URL, crawl site, download assets, extract links

System: run command (up to 30k chars output), take screenshot, ADB screenshot and input for Android devices

Documents: read PDF, read/write DOCX, generate images (GPT Image), compress images (TinyPNG)

Data: query Firestore, list Firebase projects and storage buckets

HTTP: arbitrary HTTP requests

Knowledge base: search PKB, commit and update entries


Time Travel (Undo Turns)

You can edit any previous message in the conversation. When you do, the extension:

  1. Backs up the current workspace state to .nic_hyper_flow/undo_backups/
  2. Restores the files that existed at that point in the conversation
  3. Starts a new epoch from that message forward

This lets you undo agent actions and try a different approach without manually reverting files. Checkpoints are stored in the local SQLite database and backed by git-aware file diffing.


Project Knowledge Base (PKB)

Each project has a persistent knowledge base stored at .nic-hyper-flow/pkb_v2.jsonl. The agent can:

  • Store Q&A pairs with source references
  • Search using TF-IDF full-text scoring (runs in a worker thread)
  • Update or expire existing entries

This gives the agent a place to remember project-specific facts across sessions without depending on context window size.


Debug Visibility

Tool Cards — In the chat UI, each tool call renders as a live card showing name, arguments, status, and stdout/stderr output as it streams.

Thinking Bubbles — When a model returns chain-of-thought or reasoning tokens, they appear in a collapsible section above the response.


Remote Control App

A companion mobile app lets you send messages and stop agent runs from your phone. It uses Firebase/Firestore for pairing, presence, tunnel discovery and coordination, while live communication flows through a WebSocket exposed by Cloudflare Tunnel. The app is functional and available.

Instant Asset Transfer — The mobile app acts as a direct bridge to your VS Code workspace. Any image or file you send in the mobile chat is instantly transferred via WebSocket and saved locally into your project's assets/ folder, making it incredibly fast to shoot a sketch or screenshot from your phone straight into your codebase.

Nic Hyper Flow Remote Control UI

Diff Visualization

File changes made by the agent are highlighted inline in the editor — green for additions, red for removals — using VS Code decorations. Each chat tracks which files were touched, and you can see a before/after diff per file.


Context Window Indicator

A progress widget in the UI shows real-time token usage against the active model's context limit, so you know when a conversation is getting long.


Pricing

The extension is paid. Usage costs $18 USD/month, charged through the VS Code Marketplace. You still need your own API keys for the AI providers you want to use.


Local Data & Privacy

Everything runs locally. The extension stores:

  • Chat history and messages in a local SQLite database
  • File checkpoints for time travel in .nic_hyper_flow/
  • Project knowledge base in .nic-hyper-flow/pkb_v2.jsonl
  • API keys in VS Code's encrypted secret storage

Privacy Notice: We do not have access to your codebase. Your code never passes through our backend. We only collect your email address (during authentication) for access control and occasional email marketing, and basic tool usage statistics to improve the extension. Everything else is strict Bring Your Own Keys (BYOK) — all AI requests are made directly from your PC to the respective API providers.


Remote Control & Setup

To use the Remote Control PWA app on your phone:

  1. Ensure you have installed cloudflared on your PC.
  2. In VS Code, open the extension settings and enable the Cloudflare Tunnel option.
  3. Authenticate using the QR Code to securely connect your devices.

Bring Your Own Keys

Press Ctrl+Shift+P and select Nic Hyper Flow: Configure Models & Keys to register your API keys.
