v2.0 — Multi-model · Multi-provider

What is ASTRAICHAT?

🤖

One interface, every major AI

ASTRAICHAT gives you seamless access to models from Anthropic, xAI, OpenAI, Google, DeepSeek, and Moonshot/Kimi — all through a single, consistent chat interface. No more switching between tabs and apps.

🔐

Access ID system

Sessions are secured with a personal Access ID verified on every load. Your API keys are stored locally in your browser and never sent to our servers in plain text.

🎨

12 handcrafted visual themes

From warm and cozy to neon cyberpunk, retro Win98, or a phosphor terminal glow — each theme is fully consistent across every element of the UI.

📎

File & image context

Attach images, text files, PDFs, source code, Word documents, and more. Vision-capable models will see your images directly; text files are injected as context for any model.

💬

Persistent chat history

All conversations are saved locally in your browser. Browse, rename, or delete past chats from the sidebar at any time.

⚡

Live HTML preview runner

When a model generates HTML code, you can run and preview it instantly in a sandboxed iframe — right inside ASTRAICHAT, without leaving the page.

How It Works

1️⃣

Enter your Access ID

A personal Access ID is required on every session. Purchase one at /buy.html if you don't have one yet.

2️⃣

Add your API key

Enter your API key for the provider you want to use. Keys are stored locally in your browser — never on our servers.

3️⃣

Pick a model

Select any model from the options panel. Switch at any time — even mid-conversation. Each model uses the matching provider key.

4️⃣

Chat

Send messages, attach files or images, and toggle reasoning/thinking for supported models. Use the sidebar to browse previous chats.
