Every AI vendor wants you locked into their model. Cognis gives you all of them, with shared memory, persistent context, and true mid-chat switching. Not just model access. Model intelligence.
OpenAI · Anthropic · Google · xAI · DeepSeek and 15+ more, all in one workspace.
No single model is best at everything. But every platform wants you locked into one.
Single-vendor subscriptions that limit you to one AI's strengths, and force you to eat all its weaknesses.
Different accounts, different interfaces, different memory for each model. Nothing talks to anything else.
Move from Claude to GPT mid-task? Start over. Aggregators swap the model, not the conversation.
Research in one tab. Draft in another. Compare outputs manually. The interface became the bottleneck.
Teams either overpay for one model's weaknesses, or waste hours switching between three AI tabs.
T3 Chat, Poe, and a dozen aggregators let you switch between models. But switching isn't the same as using them intelligently.
Context that travels
across every model switch
Memory that persists
across sessions and models
Integrations connected
to your actual work
Observability
into what each model did and why
Multi-model access is just a feature. Not a platform.
Access GPT-5, Claude Opus, Gemini 2.5, DeepSeek v3, Grok 3, Llama 4, and 15 more. Add a new model the day it launches. No extra subscriptions, no extra accounts.
Research with Claude. Draft with GPT. Generate images with Gemini. Switch per message, not per conversation. No competitor offers context continuity across providers the way Cognis does.
Fork any message. Test a different prompt, a different tone, a different model, all from the same root. Compare side-by-side, pick the winner, keep going.
Every model connects to your tools and memory. See what each one did via Dynamic Observability. Models don't just answer. They execute.
Match model strengths to task types. Get the best output, spend the least.

No competitor combines multi-LLM + context continuity + branching + observability in one platform.
No vendor lock-in. No context loss. No "restart the conversation because you switched models."
Just the right AI for every task, every time.
20+ models, switch anytime, context follows. Add any model the day it launches.
Models connected to your tools, memory, and 500+ integrations.
See what every model did via Dynamic Observability. Every step, every decision.
Interactive UI, not a plain chat box. Edit output in place. Live previews. Contextual actions.
Happy with one AI model for everything? Cognis probably isn't for you, and that's OK.
This feature works because of one, and enables the other. Both pair with it in real workflows.
Twenty+ models is only useful if you can see what each one did. Glassbox traces every call: which model, which tools, which sources, and what it cost.
Read the Glassbox page →Fork any message to a different model or provider. Keep both answers side-by-side. Continue the thread on whichever wins. The data model most chat tools don't have.
Read the Branching page →One platform. Every model. Full context. Real execution.
