Blackbird

Invisible AI.
On Your Desktop.

A native Windows overlay that answers anything on screen. Bring your own keys. Undetectable by Zoom, Teams, and proctors.

// inside the overlay

A Window You Control.

Sign in, drop your keys, bind a hotkey, tune the gestures. Every surface is tight, dark, and built for one-hand use during a live screen.

// settings

One panel. Everything tunable.

Interface color, hotkeys, auto-typer, opacity, chat history, API keys — all behind a single hotkey.

// auth

Account-bound

Username + password. API keys, tier, and preferences follow you across machines.

// status

Always-visible state

Version, auth, tier, session timer — no guessing what's loaded.

// hotkeys

Bind every action

Toggle, screenshot, text capture, send, type-last — all global, all rebindable, all persist across launches.

// gestures

Hands stay on the mouse

Hold LMB or RMB for the configured duration. No keyboard reach, no focus switch, no app activation.

// connections

Link ChatGPT or BYO keys

OAuth via PKCE for ChatGPT — no credentials stored. Plain BYO API keys for every other provider, encrypted at rest via Windows DPAPI.

// capabilities

Key Features.

// providers

Twelve providers. One picker.

Gemini, OpenAI, Claude, Kimi, OpenRouter, DeepSeek, xAI, Mistral, Perplexity, Ollama, ChatGPT, Codex. Switch in one click. Selection persists.

// system-prompt

Tune the model's behavior

Edit the system prompt once. It rides on every request — chat, screenshot, text-capture. Restore-default in one click.

// auto-typer

The AI types your answer

Humanized keystrokes: WPM, jitter, fatigue, adjacent-key slips with delayed correction. Tap Ctrl mid-stream to pause. Three presets, full manual control.

// text-capture

When screenshots come back black

Some apps protect themselves from screen capture. Pull the text directly from the window's accessibility tree instead — the AI gets readable content even when the bitmap is useless.

// stealth

Invisible to capture

OBS, Zoom, Discord screen-share, Teams, Game Bar — they see what's behind Blackbird, not Blackbird itself. OS compositor-level exclusion. Always on top. Click without stealing focus.

// chat-history

Local, optional, off by default

Toggle on and every Q&A is archived to AppData as plain text plus the attached screenshots. Never uploaded. The AI doesn't see archived turns — each session starts fresh.
