01 Claude, GPT, and Gemini on one canvas best for: Frontier variety without vendor lock-in
One workspace where Claude, GPT, and Gemini answer side by side, picked per message, each seeing exactly the context you assembled: fork tangents, reference exact messages with @, merge chats into one draft. No X account involved, and the usage meter is visible instead of a shifting rolling window. No live X firehose, though; if that is why you use Grok, nothing here replaces it.
pricing · Free on community models; paid plans from $5/mo, every paid plan reaches every model.
best for: The most complete product
The GPT-5.6 family, the most polished apps, full-duplex voice, image generation, agents, and the largest ecosystem. What you give up from Grok is the real-time X data and some price aggression; what you gain is maturity across every surface.
pricing · Free; Go $8/mo; Plus $20/mo; Pro $200/mo.
best for: Long-form reasoning and writing quality
The models people choose when the answer has to be right, with the most user-controllable memory in the category and Claude Code bundled at $20. Slower-burning than Grok by design; no live social data.
pricing · Free; Pro $20/mo; Max $100 to $200/mo.
04 Google's assistant and bundle best for: Long context and bundle value
A million-token context window on paid plans, a $4.99 entry tier, and the Google Workspace integration Grok cannot match. Conversations are strictly linear and chat organization is thin, but the capacity for the price is unmatched.
pricing · Free; AI Plus $4.99/mo; AI Pro ~$20/mo; AI Ultra $100 to $200/mo.
best for: Cited answers from live web search
If Grok's DeepSearch is the part you would miss, Perplexity is the dedicated version of it: live search with citations on every answer, Deep Research reports, and a model picker that includes GPT, Claude, Gemini, and Grok itself on Pro.
pricing · Free; Pro $20/mo; Max $200/mo.
06 Self-hosted UI for local and API models best for: Running your own stack
Self-hosted and open source, with xAI's API among the many providers you can point it at, so you can even keep Grok models while leaving the Grok app. You own setup, upkeep, and per-token costs.
pricing · Free and open source; you pay for hardware or APIs.
