NanthAI

NanthAI Edge is a multi-model AI chat platform that lets you connect your own OpenRouter API key to access over 150 models (including GPT-4, Claude, Gemini) without a monthly subscription — you pay only per-token usage through OpenRouter.

What is NanthAI Edge?

NanthAI Edge is a bring-your-own-key (BYOK) AI chat app that connects to OpenRouter to give you access to 150+ models from OpenAI, Anthropic, Google, Meta, Mistral, and others. It runs on iOS, Android, and the web, and it was built by NanthAI. You link your OpenRouter account, choose models, and pay only for the tokens you actually use — no platform markup, no monthly access fee. The app takes your text prompts and returns AI-generated responses, documents, images, or audio, depending on the model and tools you enable.

Key Features

• Multi-model chat — Add up to three models to one conversation, compare answers side-by-side, fork messages, or regenerate with a different model. Queue follow-ups while the AI is still responding.
• Custom personas — Create AI identities with their own name, avatar, system prompt, model, temperature, and tools. Assign them to chats, scheduled jobs, or autonomous sessions (Pro).
• Persistent memory — Edge can remember facts across conversations — preferences, projects, writing style — categorised and searchable. Set it to save automatically, ask first, or stay off (Pro).
• Search and research — Basic web search on the free tier; Pro unlocks three complexity levels and a full research pipeline that plans queries, iterates on sources, and synthesises cited papers.
• Scheduled jobs — Set recurring AI tasks with up to five steps, each with its own model, persona, and search mode. Results appear as regular conversations (Pro).
• Autonomous sessions — Let multiple personas debate or brainstorm without your input, with moderator and stop-on-consensus options (Pro).
• File and knowledge base — Attach images, PDFs, DOCX, and Office documents to any chat. Pro adds a persistent knowledge base for reusable reference material.
• Document generation — Draft DOCX, XLSX, PPTX, CSV, and Markdown files from chat. Pro keeps source-backed citations and review history.
• Integrations — Connect Google Drive, Calendar, Gmail, Microsoft 365, Notion, Slack, Cloze, and Apple Calendar. Use them inside chats, personas, and jobs (Pro only).
• Audio, image, and video generation — Generate images, music (Google Lyria), and videos (Veo, Seedance, Wan) from prompts. Outputs are saved to the Knowledge Base.
• Ideascapes — Switch any conversation into a spatial canvas with movable nodes and non-linear paths (Pro).

Who is it for?

• Researchers and analysts — Use the research pipeline and multi-model comparison to gather cited information from multiple sources quickly.
• Professionals with existing AI access — Anyone who already has an OpenRouter account can use Edge as a frontend that adds collaboration, scheduling, and memory without extra cost.
• Indie developers and power users — Build custom AI workflows with personas, scheduled jobs, and autonomous sessions, all integrated with their own tools and documents.

What can you do with NanthAI Edge?

• Compare model outputs in real time — For example, ask GPT-4.1, Claude Sonnet, and Gemini 2.5 to draft an analysis and compare their responses side by side.
• Automate daily briefings — Set a scheduled job that searches the web, synthesises findings, and delivers a report to your inbox every morning.
• Generate documents from conversations — Turn a chat about a project plan into a formatted DOCX file with cited sources, ready to share.
• Research a topic autonomously — Launch an autonomous session where two personas debate a question, review each other’s arguments, and produce a consensus summary.

How does NanthAI Edge work?

1. Sign in and connect — Create a free account, then link your OpenRouter account (Edge walks you through the setup in about a minute).
2. Choose your AI — Pick from over 150 models. Each model’s strengths are described, and you can switch mid-conversation.
3. Only pay for what you use — Add credit to your OpenRouter account. Most conversations cost a fraction of a penny. Your balance is always visible, and Edge sends low-credit alerts.
