Notion and Slack: the old way vs. Letaido

1Check the content calendar for drafts ready to review
2Open each draft and skim it
3Look up who reviews it
4Write a Slack message and tag them
5Mark the draft as sent for review

When a page in my Content calendar database in Notion changes to Status 'Ready for review', post it to #content-review in Slack: tag the person in its Reviewer property (or name them if I can't match them in Slack), and add the title, a two-line summary of the draft and the page link. Then tick the page's 'Review posted' box so each draft is only posted once.

Frequently asked

Does Notion integrate with Slack? +

Yes. Notion's own Slack integration sends Slack notifications when a database page is added or a property changes, and saves one Slack message at a time to a Notion database. Letaido's AI agent, Leta, adds jobs on top that need judgement, like summarising a draft for its reviewer or writing up flagged messages as Notion requests.

How do I connect Notion to Slack with Letaido? +

Connect Notion and Slack once in Letaido. Share the databases and pages a job needs with your Notion integration, and invite the Letaido bot to each channel it should read or post in. Then describe the job in chat, or paste a prompt from a job on this page.

Can a change in Notion start a job? +

Yes. A Notion event, such as a page's status changing, can start a job like posting a draft to #content-review when it's ready. Notion events need a webhook subscription in your Notion integration, verified once with the token Notion sends.

Is there a way to save Slack messages to Notion? +

Yes. React to a message with :memo: and Leta adds it to your requests database with a title, a one-line summary, who asked and a link, then replies under the message. It skips messages already logged. This reaction job skips replies inside threads. Switch on the reaction_added event in your Slack app settings first.

Can it answer questions in Slack from our Notion docs? +

Yes. Mention @Letaido with a question and Leta reads up to 3 Notion pages whose titles fit, nested blocks included, then answers in the thread with links. Notion search matches page titles only, and Leta answers only from the pages shared with your Notion integration.

Do Notion Custom Agents work with Slack? +

Yes, but Notion Custom Agents need a Business or Enterprise plan, their runs use Notion credits, and a Slack admin must connect Slack to the Notion workspace first. Letaido's agent works with Notion, Slack and the other apps you connect, in the same job.

Will it ask before it posts in Slack or changes Notion? +

Allow all read operations once per app; approve each kind of write once.
