Dust vs Sema4.ai (2026): which should you pick?

Pick Dust if

• Fits if your company wants agents that answer from its own docs and chats
• Works for organizations that need their data kept in the US or the EU

Look elsewhere if

• Tight if you're staying free, as the Free seat is 500 credits once and never refills
• Not for you if you need more than 3 data sources, 5 MCP servers or 5 spaces without an Enterprise deal
• Skip it if you need audit logs, SCIM or custom data retention, which sit on the custom-priced Enterprise plan
• Pricey if heavy users need Max, at $120 a seat a month billed yearly or $150 monthly
• Watch out: credits don't roll over, prices exclude VAT, and there's no phone or desktop app

Pick Sema4.ai if

• Fits if you are an enterprise team that needs a record of what agents did
• Makes sense if you work on Snowflake and want agents there

Look elsewhere if

• Not for you if you want a price, as none could be read
• Skip it if you can't run a cluster, since self-hosting needs EKS or AKS and an identity provider
• Watch out: the docs say the API reference and SDKs are not yet written up for Version 3
• Not for you if you want a free plan, because none is on record

Dust

• The Free seat is a one-time allowance of 500 credits, not a monthly quota; once it is used, free users are prompted to request an upgrade.
• The self-serve Business plan covers teams of up to 100 and is limited to 3 data source connectors, 5 remote MCP servers and 5 spaces.
• SCIM provisioning, audit logs, custom data retention and single-tenant deployment require Enterprise.
• Monthly credits reset each billing period without rolling over, and listed prices exclude VAT.

Sema4.ai

• No pricing could be read: the vendor's site answered with a bot check, and the documentation states no prices.
• The docs say the API reference, the SDKs and deeper analytics surfaces are not yet written up for Version 3.
• Self-hosting needs your own cluster, such as AWS EKS or Azure AKS, plus an identity provider.

Dust

Agents with company context

Agents draw on connected company data from sources such as Slack, Notion, Google Drive, GitHub, Salesforce and Zendesk to answer questions and take action.

Model choice per agent

All plans include 20+ models from OpenAI, Anthropic, Google, Mistral and DeepSeek. The model is chosen per agent, and none is locked to a higher plan.

Schedules and triggers

Multi-agent workflows can run on a schedule or in response to events. Dust also lists Zapier, Make, n8n and Power Automate as supported automation platforms.

Spaces and permissions

Spaces segment data by team, and a two-layer permission model separates what agents can access from who can use them. The Business plan includes 5 spaces.

Frames

Frames turn agent output into interactive dashboards, reports and memos that a team can explore and work on together.

Slack and Chrome extension

Agents can be mentioned in any Slack channel or messaged directly, and a Chrome extension opens them in a sidebar on any web page.

Sema4.ai

Projects with shared context

Projects hold files, instructions, data, memories, skills and integrations, and you can chat with a Project to build or change what is inside it.

Workflows and work items

Workflows run with triggers, including a bound email address, and produce work items with a drafted answer that people can confirm, correct or send back.

Connections and data sources

The docs list providers such as SharePoint, Microsoft Teams, Gmail, GitHub, Slack and Stripe, MCP servers, and Snowflake and Postgres data.

Audit and evidence record

Administration pages cover audit lenses, deterministic execution, isolation of runs and alignment with COSO controls.

Self-hosting

Deployment guides cover AWS EKS, Azure AKS and other targets, with identity providers such as Entra ID, Okta and Auth0 for sign-on.
