Vanta: Local AI & LLM Chat

Stop switching between six AI apps.

Vanta Client connects to everything. Local models on your iPhone, cloud APIs from every major provider, MCP tool servers — one interface, one purchase, no subscription. Your keys, your models, your rules.

EVERY PROVIDER, ONE APP
Connect to OpenAI, Anthropic Claude, Google Gemini, DeepSeek, Groq, OpenRouter, Ollama, vLLM, or any OpenAI-compatible endpoint. Add a custom provider with a single URL. Switch providers and models mid-conversation. No lock-in, no walled gardens.

ON-DEVICE INFERENCE
Browse the full HuggingFace GGUF library. Download DeepSeek, Qwen, Llama, Gemma, Mistral, Phi directly to your iPhone. Run them offline — no internet, no API key, no per-token cost. Your data never leaves your device.

MODEL CONTEXT PROTOCOL (MCP)
Connect AI to external tools and live data sources. Search documentation, fetch real-time data, browse the web — all inside a single conversation. MCP works with any provider, local or cloud.

GROUP INTELLIGENCE
Put multiple LLMs in one chat room. Assign roles — Devil's Advocate, Pragmatist, Genius. Enable adversarial mode. Let Claude argue with DeepSeek while GPT moderates. Answers one model could never reach alone.

DEEP SEARCH
Web-scale research from inside a conversation. Vanta searches, reads, synthesizes, and cites — without leaving the chat. Works with any connected provider.

VOICE INPUT
On-device speech recognition. Speak instead of type. Multiple STT backends, fully offline capable. No audio sent anywhere.

PROMPT ENGINEERING
Describe the assistant you need in plain English. Vanta generates a complete, structured system prompt in seconds. Save prompts to your library and reuse across conversations.

MEMORY & CONTEXT
Vanta remembers across conversations. Automatic memory extraction, deduplication, and embedding-based recall. Configure token budgets, similarity thresholds, and summarization templates.

BUILT FOR PEOPLE WHO CARE ABOUT THE DETAILS
Live context tracking with token-level visibility. Message, tool, and system token breakdown. Auto-summarization when context runs low. Custom compaction templates. Full control over temperature, top-p, frequency penalty, and every parameter that matters.

Text-to-speech powered by ElevenLabs. Markdown and code rendering with syntax highlighting. Dark mode throughout.

This is not a ChatGPT alternative. It's the app that connects to ChatGPT, Claude, DeepSeek, Gemini, Grok, and every open model through one interface. Think Spark for email, but for AI.
