AIChat.fm is a browser-based “AI hub” that gathers the most popular large-language models into one clean dashboard.
Main introduction
The site positions itself as the fastest way to chat with GPT-4, Claude-3, Gemini, Llama-3, Mistral, Grok and other frontier models without installing anything. Users simply land on the homepage, pick a model from the drop-down, and start typing. No account is required for the first few messages; after that a free login unlocks longer context windows and higher daily quotas. The service is fully hosted—no API keys, no credit-card forms—so students, marketers, developers and casual testers can compare answers from rival models side-by-side in real time.

Key features
1. Multi-model playground: switch between 10+ state-of-the-art LLMs in one click, each clearly tagged with version number and knowledge cut-off.
2. Side-by-side mode: open two models concurrently and watch them answer the same prompt in parallel columns, making A/B testing or style comparison effortless.
3. Zero-setup access: the site fronts its own unified API keys, so visitors skip the normal OAuth or billing steps that individual providers require.
4. Context-aware chats: every conversation keeps a rolling 32 k token memory (exact limit varies by model) and can be renamed, exported to Markdown, or shared via a public URL.
5. Prompt library: one-click templates for copy-writing, code debugging, translation, SEO, lesson planning and more, crowd-sourced and up-voted by the community.
6. Cost transparency: each response shows the estimated token cost and remaining free quota; power users can jump to an affordable pay-as-you-go tier without leaving the chat.
7. Keyboard-first design: slash commands (/gpt4, /claude, /summary, /translate) let heavy users switch models or trigger actions without touching the mouse.
8. Privacy promise: chats are encrypted in transit and automatically purged after 30 days unless the user explicitly saves them.
9. Mobile PWA: install the page as an app on iOS or Android for full-screen, offline-cached access to the interface.
10. Weekly model drops: the banner announces new checkpoints (e.g., GPT-4-turbo-preview) as soon as they are cleared by the providers, usually within 24 hours of release.

In short, AIChat.fm is a friction-free, vendor-neutral arena where anyone can benchmark, combine and iterate on the world’s best generative models without creating multiple accounts or juggling API bills.
