The shared memory across agents in the same workspace is cool 👍 can you also set boundaries so certain agents only access certain data, or is it all-or-nothing?
Sim
@ding_hao that's right! You can guard agents by only giving them access to certain operations (I.E. Gmail draft instead of Gmail write).
@emirkarabeg The per-node flexibility between chat, canvas, and code is what other tools get wrong. Curious, which mode do most of your users end up living in?
Sim
@abhiranjan_mehta most users work inside chat end-to-end.
For someone who's already deep into LangGraph or CrewAI, is there an import path, or would they basically be starting from scratch rebuilding their agents in Sim?
Sim
@diego_joaquin1 that's a great question. You can pass your code/repo to the Sim agent and it will build it from end-to-end.

This is really amazing. So do you have templates for the workflows?
How is it different to N8N or Zapier?
Sim
@chilarai no, most teams just build in the chat! No need for templates.

love that files and tables live in the same workspace layout, context switching between three different DBs and vector tools completely breaks agent memory. amzing launch
Sim
@priya_kushwaha1 thanks so much! You can think of Sim as a 'brain' that houses and interacts with data across knowledge bases (vector DB), tables, files, and workflows.
@emirkarabeg such a good direction
This looks promising! How does Sin handle multi agent collaboration ? Can different agents here context and coordinate on the same workflow?
Sim
@gordon_bennett great question! We have a concept of "memory" and if you pass in the same conversation ID to multiple agents, they're able to have context in the same workflow or even across multiple workflow runs. It's pretty neat, actually. Feel free to try it out.
How does the pricing work for an open-source project, especially once you start scaling beyond a handful of agents and hitting those 1,000+ integrations?

@hanifekrkir2f it's free forever! Open source Apache 2.0.
