15 T3.chat Alternatives for Fast Multi-Model AI

T3.chat (built by Theo Browne) offers multi-model access at $8/month with a focus on speed and side-by-side comparison. It stores data on-device for privacy.

Here are 15 alternatives, from similar multi-model platforms to single-provider options.

1. Go Ask Chat

Same price: $8/month. Access to 28+ models including GPT-5.2, Claude Opus 4.5, Gemini 3 Pro, Grok-4.1, and DeepSeek. More models than T3.

Key differences from T3:

• Voice chat with any model — Talk to Claude or GPT, not just text
• Model switching mid-conversation — Same chat, different models
• macOS overlay — Hotkey to summon AI from any app
• Infinite memory — References past conversations

T3 focuses on speed and comparison. Go Ask Chat has more features at the same price.

Best for: Multi-model access with voice and memory

2. Poe

$19.99/month for 100+ models. More expensive than T3 but access to more models and a bot creation marketplace. If you want to try obscure models or build custom bots, Poe has that.

Best for: Maximum model variety, bot creation
