Multi-model AI chat apps let you talk to GPT, Claude, Gemini, Grok, and open models from one interface instead of four subscriptions. TypingMind and IMAI are bring-your-own-key frontends; Magai bundles models into a team workspace; Suprmind runs the same prompt across several models and reconciles the answers.
The bring-your-own-key approach is usually cheaper for heavy users, since you pay API rates instead of a flat $20 per model.
How to choose
If you already have API keys, a BYOK frontend gives the most control and lowest cost. If you want zero setup or team sharing, choose a bundled workspace. Check whether local/offline models are supported if privacy matters.

Frequently asked questions
Is bring-your-own-key cheaper than ChatGPT Plus?
For most people, yes. Light personal usage at API rates usually costs less than a $20-per-provider consumer subscription. Heavy daily use of top-tier models can exceed that, so check your usage.
Do these apps store my conversations?
BYOK apps like TypingMind and IMAI store chats locally or in your own storage; bundled workspaces store them server-side. Each tool page notes the maker's stated data policy.
Can I run local models?
IMAI runs local LLMs on iPhone and Mac. For other apps, check the tool page — BYOK frontends often accept custom endpoints, while cloud-only workspaces do not support local models.
