01 · Platform work
A workspace for builders. An outcome for operators.
Sim is a workspace for building and operating AI systems. Chat can scaffold resources, the visual builder exposes workflow logic, and the API and SDK support code-led development. Tables, files, knowledge bases, deployments, and logs live beside the workflows.
Safivo is narrower by design. It does not ask an operations team to assemble an AI workspace. It maps a repeatable process across the systems the team already uses, then keeps model judgment inside explicit checks and approval rules.

02 · From build to run
Build an AI system or launch a business workflow.
Consider provision access for an approved request. The happy path is only part of the job. The system also needs a known response when the evidence is incomplete or two systems disagree.
Needs review
The requested role exceeds policy. Hold provisioning and ask the manager to approve.
03 · Trust boundary
The trust boundary should ship with the workflow.
Sim makes the workflow inspectable. Its logs show execution block by block, including outputs, errors, timing, and cost. Builders can use ordinary workflow blocks for deterministic steps and add Agent blocks where reasoning is useful.
Safivo makes the trust boundary the main design object. A model can classify or extract. A fixed check can verify a limit. A person can approve a sensitive action. The run record keeps the trigger, evidence, decisions, and writebacks together.

04 · Last-mile work
Reach the old portal as well as the modern API.
Sim states that it supports 1,000+ native integrations, major model providers, and MCP for services that are not built in. It can deploy workflows as an API, hosted chat, or MCP tool.
Safivo focuses on operational reach: 3,000+ tools, 10,000+ ready actions, any public API, and web application work when no useful API exists. This is important when one process crosses both modern SaaS and older business systems.

05 · When Sim wins
Use Sim when the workspace is the product.
Sim is the stronger choice when the team wants a general AI development environment. Its visual builder, workspace data, knowledge bases, deployment options, and self-hosted Apache 2.0 core provide room to build products as well as internal automations.
It also supports bring-your-own model keys and local models. That matters to teams that want control over providers, infrastructure, or model economics and have the engineering capacity to run the system.
