Vanta: Local & Cloud AI Chat

Buy Vanta once. Own your AI setup. No subscription, no lock-in and a direct line to the developer, so the features you need can actually get built.

Stop switching between AI apps—and stop giving every AI company your data.

Vanta brings local models, private memory, offline voice, vision, PDFs, images, cloud APIs, self-hosted servers, and MCP tools into one powerful AI client.

Build a fully private AI setup that runs on your device, or connect cloud services only when you choose.

No Vanta account. No recurring subscription. Buy it once and own your AI.

PRIVATE BY CHOICE

Your entire AI workflow can stay on your device:

• Run GGUF and MLX models locally • Transcribe voice offline • Store memory and semantic recall locally • Chat without an internet connection • Work with images, documents, and PDFs privately • Use Vanta without an account or Vanta-owned cloud

Vanta does not force your conversations through its own servers. You decide which models, providers, tools, and services receive your data.

OWN YOUR AI

Connect OpenAI, Anthropic Claude, Google Gemini, DeepSeek, Groq, OpenRouter, Ollama, vLLM, or any OpenAI-compatible endpoint.

Add a custom provider with one URL. Switch providers and models mid-conversation. Keep your setup independent from any single AI company.

LOCAL AI, ON YOUR DEVICE

Browse and download compatible GGUF and MLX models from Hugging Face. Run supported models directly on your iPhone or iPad—offline, without an API key, subscription, or per-token fees.

With local inference, your prompts and responses stay on your device.

SEE IMAGES. READ FILES.

Chat with photos, screenshots, documents, and PDFs. Ask questions, extract details, summarize content, compare files, or continue working from an uploaded document.

Use supported local vision and document models for private workflows, or connect cloud models when you need more power.

EVERY PROVIDER, ONE APP

Use local, cloud, and self-hosted models through one interface. Switch models during a conversation without copying prompts between apps.

Bring your own API keys and pay providers directly. Vanta does not place another subscription between you and your models.

TOOLS THROUGH MCP

Connect supported models to MCP servers for web search, documentation, live data, and your own tools.

Use tools with local, cloud, and self-hosted models. You choose which servers to trust and what information to share.

GROUP INTELLIGENCE

Put multiple models in one conversation. Assign roles, let them challenge each other, compare their answers, and combine their strengths.

Let Claude argue with DeepSeek while GPT moderates—or build your own group using local and cloud models.

DEEP SEARCH

Search the web, read sources, synthesize findings, and return cited answers without leaving the conversation.

MEMORY YOU CONTROL

Vanta can remember useful information across conversations and recall it when relevant.

Memory can remain entirely on your device. Control extraction, deduplication, token budgets, similarity thresholds, and summarization—or disable memory completely.

PRIVATE VOICE INPUT

Speak instead of type using on-device speech recognition. Keep transcription offline, or choose an external speech provider when preferred.

PROMPT ENGINEERING

Describe the assistant you need in plain English. Vanta generates a structured system prompt that you can edit, save, and reuse with any model.

POWER-USER CONTROL

See how your context window is used with message, tool, and system-token breakdowns.

Automatically compact long conversations, customize summarization templates, and control temperature, top-p, penalties, context limits, and other model parameters.

ALSO INCLUDED

• Markdown and syntax-highlighted code • Text-to-speech with ElevenLabs • Themes and appearance controls • Mid-conversation model switching • Custom providers and endpoints • No Vanta account required • No recurring subscription

Vanta is not another closed AI service. It is the client that brings local, cloud, and self-hosted AI together—while letting you decide what stays private and what connects to the cloud.
