HakkoAI

Meet HakkoAI — your AI Game Companion. Live, custom-built, and impossible to forget.

Most AI just sits there waiting for you to type. HakkoAI plays with you, learns the character you want, and remembers the moments that matter — across every session, for as long as your story keeps going.

YOUR AI GAME COMPANION

Stop typing mid-fight. HakkoAI talks to you in real time.

- Live Voice Chat — hands-free voice conversation while you play.

- Proactive Chat — your AI watches the moment and reacts on its own, dropping timely tips, cheers, and reactions.

- Concise Game Mode — short, accurate answers when seconds matter.

- Plays alongside Genshin Impact, Honkai: Star Rail, and your full mobile library.

—— BUILD A CHARACTER THAT'S TRULY YOURS ——

Build A Character That's Truly Yours

The default companion is just the start.

- Customize Avatar, Voice, and Soul — personality, values, the way they speak to you — all from scratch.

- AI-Assisted Creation — describe a vibe, get a starting persona in seconds.

- One-Tap Remix — found a character you love? Make them sweeter, darker, weirder, more *you*.

- A curated feed of Featured, Official, Mafia, School and more — start from inspiration, never from a blank page.

Stories That Come Alive

Don't just imagine the scene — see it.

- Contextual Image & Video Generation — your dialogue becomes high-fidelity visuals inside the chat itself.

- Animate — tap once to bring any moment to life.

- Background Switch — set any AI-generated scene as your conversation backdrop.

Remembers Every Moment

The end of AI amnesia.

- Agentic Retrieval Memory — a layered Persona / Memory / Context engine that recalls the nuances of past chats, not just the last 20 messages.

- Pinned Memory — lock in the lines that matter. Yesterday or 151 days ago, your companion still knows.

- Character Events — your shared history becomes a visible, editable timeline your AI will actively reference next time you talk.

Chat Modes For Every Vibe

- Roleplay Mode — Step into any character, any world.

- Romantic Mode — unfiltered, intimate, emotionally deep.

- Concise Mode — short, sharp, built for gameplay.
