Slack AI understands your Slack. Ray works outside it.

You already pay for Slack. Here is exactly where its built-in AI stops and an agent starts, checked against Slack's own documentation.

Compared against Slack AI's own pages. Last checked August 2026.

What Slack AI is

Slack's AI is bundled into paid Slack plans rather than sold as an add-on, and what you get depends on the plan: Pro gets conversation and thread summaries, huddle notes and search filters, while Business+ adds search answers, recaps, file summaries, translations and Slackbot. Separately, Workflow Builder connectors take actions you configure in advance in tools like Jira and Asana. Slack AI's own page

One message, two outcomes.

What happens to the same sentence in your channel, depending on which of the two is in the room.

Can someone file the bug I hit in staging, it is blocking the release.

Ray

  1. Files it in Linear from the thread itself
  2. Shows you the approval card before it writes anything
  3. Follows it into the tools that live outside Slack

Slack AI

  1. Finds and summarises the thread whenever you ask
  2. Runs the connector steps someone wired up in advance
  3. Reasons about your Slack content, not your Linear

The difference, in one table.

What each one is for, side by side. Slack AI's column comes from their own pages, checked August 2026.

What Ray costs

Free covers 25 tasks a month plus a one-time 50-task starter grant that never expires. Pro is one flat price for your team’s size: $49 a month for 1 to 3 people, $99 a month for 4 to 10 people, $199 a month for 11 to 25 people. No seats, and using Ray more never costs more.

What Slack AI costs

There is no separate AI price any more. The Slack AI add-on was withdrawn from sale in August 2025 and the features now come with the paid plans, so the cost of Slack AI is the cost of the Slack plan your workspace is already on. Prices vary by currency and region, so check Slack's pricing page for yours. their pricing page

Which one you should pick

The honest version, their side first.

Choose Slack AI if

  • What you need is to catch up on Slack itself. Summaries, recaps, huddle notes and search answers are exactly that, they are native, and you are already paying for them.
  • You want zero new vendors, zero installs and no additional review. Nothing beats what is already in the product.
  • Your work lives in Salesforce, where Slackbot goes deepest, or you need enterprise search across Drive, GitHub, Gmail and Notion on Enterprise+.

Choose Ray if

  • The problem is not catching up on chat. It is that the work described in chat never gets filed, chased or finished anywhere else.
  • You want an agent that reads a thread and decides which tool to act in, rather than workflows you design step by step in advance.
  • You want a structural approval card in front of every write, so nobody has to trust that an automation was configured correctly.

What Slack AI does not do

Each one checked against their own documentation, August 2026. If any of this changes, tell us and we will fix it.

  • Slack's recaps summarise unread Slack channels. We found no scheduled digest of work state across your other tools in Slack's own documentation. their docs
  • Workflow Builder needs a paid Slack plan, so the connector actions are not available on the free tier at all. their docs

Questions people ask.

The short answers are here. If we have not covered something, just ask.

Try Ray with your own team.

Free to start, no card. Ray sees only the channels you invite it to, and nothing sensitive happens without your approval. Or read Slack AI for their side of it.
