Lexika AI: Memory & Laboratory

Every AI model. One memory. One workspace.

Claude, GPT, Gemini, Grok, DeepSeek, and more — in a single professional workspace. Stop juggling apps, re-explaining your context, and paying for overlapping subscriptions.

YOUR AI REMEMBERS YOU
Every conversation can draw on a Brain: a knowledge base that holds your projects, preferences, and decisions. Every model reads from it, so switching from Claude to GPT mid-project costs you nothing. And you stay in control — Lexika saves new facts only with your permission and shows you which memories shaped each answer.

THE RIGHT MODEL, EVERY TIME
Auto mode reads your prompt and routes it to the best model for the job. Auto Eco favors speed and efficiency; Auto Premium favors maximum capability. Prefer to choose yourself? A model gallery with benchmark scores and knowledge cutoffs helps you pick with confidence.

SWITCH MODELS MID-CONVERSATION
Type @ to bring any model into the thread. Full context carries over. No copy-pasting, no starting over.

THE LABORATORY
For questions that deserve more than one opinion.
The Council: several models answer independently, critique each other's work anonymously, and a chair model delivers the strongest synthesis.
Agentic Research: give Lexika a topic and it plans the searches, reads the sources, follows the leads, and returns a structured, fully cited report.

BUILT FOR TEAMS
Shared workspaces with roles, permissions, and credit management in one dashboard. Share any conversation with a link — teammates can fork it and continue on their own.

ONE SUBSCRIPTION, NOT FOUR
The same frontier models, one workspace, lower total cost.
