PersonaLLM

Create AI characters with persistent memory. Generate images and video in chat. Run models locally or bring your own API — a studio for writers and worldbuilders.

Create AI characters that actually remember you. PersonaLLM is a deeply customizable AI character chat and creative writing app for iOS — with on-device memory, in-chat image and video generation, local LLM support, and tools built for authors and worldbuilders.

CHARACTERS WITH DEPTH

Create characters with AI assistance or build them by hand. Define personality traits, goals, fears, worldbuilding, backstories, and communication styles. Import character cards, presets, and lorebooks from popular formats.

Every character gets their own accent color, avatar (upload or AI-generate), writing style, and scenario library. Build assistants for productivity or characters for fiction — your choice.

AI THAT REMEMBERS

PersonaLLM is the only iOS character app with on-device RAG memory. Your AI recalls names, events, and details from past conversations — not just the current one. Upload documents (PDF, TXT, and more) to give characters specialized knowledge. The lorebook system injects relevant lore automatically based on keywords, and auto-extraction learns new facts as you write.

IMAGES & VIDEO IN YOUR STORY

Visual Story mode generates images and video directly inside the conversation as the narrative unfolds. Choose your own image and video providers or connect your own ComfyUI server with custom workflows for full control.

YOUR MODELS, YOUR CHOICE

Run LLMs entirely on-device with MLX — completely private, no server needed. Or connect to any compatible API: OpenRouter, Ollama, LM Studio, KoboldCpp, llama.cpp, or vLLM. Save multiple provider presets and switch instantly.

VOICE BUILT IN

Kokoro neural text-to-speech reads responses aloud with separate narration and dialogue voices. WhisperKit provides on-device speech recognition. Have full voice conversations with your characters — no cloud required.

BRANCHING STORIES

Fork any conversation at any message. Explore alternate storylines with a visual branch tree. Swipe between response variants. Let Autopilot mode run the narrative hands-free while you watch the story unfold.
