Pascual Companion — AI Desktop Friend users statistics

Your AI companion that lives on your screen — sees, hears, talks, and remembers. 3D VRM avatar with voice. By Pascual Labs.

Meet Pascual Companion — the ultimate interactive AI companion that literally lives on your screen. Not a tab. Not a popup. A live, animated window floating on top of everything — on top of your browser, code editor, or movies. It sees your screen, hears your voice, responds in real-time, and remembers everything you tell it.

This is not just a chatbot. This is a presence.

👁️ SEES — Screen Context Turn on the "Sees Screen" mode — and your companion will know which active tab is open. Ask "what is written here?" to get a summary of any article. Open GitHub, and she will help debug code right from your screen. Watch YouTube, and she will comment on it along with you.

👂 HEARS — Voice Input Two modes to fit any work rhythm:

• Push-to-Talk (PTT) — click or hold the mic button, speak, and release.
• Hands-Free — enable once, speak continuously, and she listens automatically.

If the browser blocks microphone access, the extension will automatically detect it and open a click-to-fix guide tab.

💬 TALKS — Four TTS Engines

• Web Speech API — free, instant, works offline.
• OpenAI TTS — warm, high-fidelity premium voices (alloy, ash, coral, onyx, shimmer, etc.).
• ElevenLabs — ultra-realistic speech synthesis with voice cloning and 37+ default characters.
• Piper Local — 100% offline local voice generation inside the browser using WebAssembly.

All premium modes support true lip-sync where the avatar's mouth movements are synchronized in real-time with the audio signal via the Web Audio API.

🧠 REMEMBERS — Long-Term Memory Every few messages, the extension automatically compresses your chat history into a brief summary + specific facts about you. This context summary is fed back into the system prompt for subsequent prompts. The companion remembers your name, what you do, your style, interests, and preferences, using it to build a natural long-term relationship.

Memory is stored separately for each avatar and language, and can be cleared in one click.

1. Intercept the audio stream.
