Relevance AI vs Sim

Relevance AI

• Sales and support teams automating research, outreach and CRM updates
• Building multi-agent workflows on a visual canvas without code
• Organizations that want to bring their own model API keys

Sim

• Teams building internal agents that share knowledge bases, tables and logs
• Developers who want a visual builder plus an API and a CLI
• Organizations that need to self-host an open-source agent platform

Relevance AI

• The Free plan has been retired for new and existing accounts, so every organization needs a paid plan.
• Plan Actions reset at each renewal, and extra Actions cost $80 per 1,000.
• Calling and meeting agents and the analytics dashboard start at Team; SSO, RBAC and audit logs are Enterprise only.
• The website's pricing page lists only Enterprise; Pro and Team prices are published in the documentation.

Sim

• The Free plan's 1,000 credits are a one-time grant with no weekly refresh, and it allows 1 workspace and no teammates.
• Every workflow run carries a base charge of 1 credit, even when you bring your own model keys.
• Sim Mailer, KB Live Sync, sandboxes and Slack Connect start at Max; access control and SSO are Enterprise only.
• The desktop app is for macOS only (macOS 12 or later); on other systems Sim is used in a browser.

Relevance AI

Agents and Tools

Agents complete tasks on their own using Tools, which are assembled in a no-code builder from API calls, LLM prompts and custom code. Both are unlimited on every plan.

Workforces

A visual canvas connects specialist agents into a team, with AI-driven handoffs, fixed sequences or conditional logic deciding how work moves between them.

Invent

A built-in agent that works through a business process with you, then creates the Agents, Tools, Triggers and Workforces for it and proposes improvements after launch.

Chat on web and mobile

Agents and Workforces can be @mentioned in a chat interface at chat.relevanceai.com, in a desktop app, and in native Android and iOS apps.

Integrations and triggers

Native integrations ship with ready-made actions and triggers, and a Pipedream connection extends the catalog to 2,000+ services. Custom API calls cover the rest.

Actions and Vendor Credits

Plans count Actions, one each time an agent runs a Tool, separately from Vendor Credits, which pass model and tool costs through with no markup.

Sim

Workflow builder

Agent logic is laid out as connected blocks: agents, API calls, functions, conditions, routers, loops, parallel branches and human-in-the-loop steps.

Building in Chat

Describe a system in plain language and Chat scaffolds the workflows, tables and knowledge bases, which you then open, run and refine in the builder.

Knowledge bases, tables and files

Knowledge bases draw on uploaded documents and on connectors to sources such as Notion, Google Drive, Confluence and SharePoint. Tables hold structured rows, and files store agent inputs and outputs.

Triggers and deployment

Workflows start from a schedule, a webhook, an RSS feed or a table event, and are deployed as an API endpoint, a chat interface or an MCP server.

Logs and cost tracking

Each run is traced block by block, with token counts and cost per model, and alerts can be set on the logs.

Enterprise governance

The Enterprise plan adds SSO and SCIM provisioning, permission groups that decide which models and integrations a group may use, audit logs and data retention settings.
