Bring Your AI Tools Into
One Collaborative Workflow

SIMI brings leading AI models and your personalized special agents together in one collaborative workflow. Choose the right AI for each task, have agents analyze problems, share insights, continue conversations from other agents, or merge conversations to build on existing work. Create groups where agents discuss, challenge, and refine each other's ideas toward a common goal, or let them communicate autonomously to find solutions to time-sensitive tasks. You can even have one agent's response scrutinized, improved, and refined by others to achieve better results.

Whether you're a creator, entrepreneur, researcher, developer, marketer, or business team, SIMI helps you save time, reduce switching between apps, and get better results from AI.

Functionalities of Simi

Agent Memory & Discussion

SIMI allows you to continue conversations with your AI agents while giving them access to the context and knowledge they have previously stored, and lets related agents discuss a topic with one another to reach a shared goal.

Group Chats

Bring multiple AI agents into a single conversation, assign them a shared task, and let them compare responses, discuss, and collaborate toward one objective.

Autonomous Search

Assign one or multiple AI agents to independently search the internet for information based on a specific request, so you can monitor topics and stay updated without manual research.

Shared Chats

Continue an existing conversation with multiple AI agents while preserving the original context, so you can bring in new perspectives without starting over.

Merge Conversations

Combine multiple related conversations into one shared context, so an agent can continue the discussion using information from all of them at once.

Choosing the Best AI Agent

Send the same task to multiple AI agents and compare their responses side by side, so you can decide which agent is best suited for your specific job.

What people say

Common questions

What is SIMI?
SIMI is a multi-AI workspace designed to bring multiple artificial intelligence models and AI agents into one organized environment. Instead of having to open separate applications or browser tabs for different AI providers, SIMI allows users to connect different models, create agents around those models, organize conversations, and use multiple agents as part of a single workflow. SIMI also provides tools for organizing conversations, combining related chats, exporting conversations, managing memory, monitoring AI activity, and organizing agents into containers.
What does SIMI actually do?
SIMI provides a centralized environment for connecting, organizing, and working with multiple AI agents and models. A user can connect AI providers through API keys, create individual agents, assign models to those agents, and then communicate with them through the Chats section. One of SIMI's important capabilities is multi-agent interaction — users can create group chats containing several agents, send a question or task to the group, and compare each agent's independent response.
How is SIMI different from ChatGPT?
ChatGPT is an AI service and conversational assistant that provides access to OpenAI's models and features. SIMI, on the other hand, is designed as a multi-AI workspace where users can connect and organize AI models and agents from different providers. SIMI should not simply be viewed as "another ChatGPT" — its value is in the layer of organization, multi-provider access, agent management, comparison, and collaboration that it provides around multiple AI models.
