Ways Notis can move work from Slack to Harvest
Turn Slack work updates into Harvest time entries
Capture work details shared in a Slack channel and create a Harvest time entry when the message includes enough information to log it accurately.
Log a work note when you react with a check
Add a designated reaction to a Slack message with complete work details to signal that it is ready for Harvest time tracking.
Capture work details sent to Notis in Slack
Send Notis a direct message with your completed work details and have it create a Harvest time entry when the information is clear.
Record clear expense notes from Slack
Turn a Slack expense note into a Harvest expense when it contains the cost and project details needed for a reliable record.
Save expense details by messaging Notis
DM Notis a project expense while it is fresh, and create a Harvest expense when the cost and project are clear.
Turn a clear Slack commitment into a Harvest task
When a Slack message clearly commits to a billable project task, create a Harvest task so it is available for tracking.
Create a Harvest task from a marked Slack request
Mark a clear project request with a chosen Slack reaction to signal that Notis should create a Harvest task for it.
Set up a Harvest project from an approved Slack kickoff
Create a Harvest project when a Slack kickoff clearly confirms the client and project details needed to set it up.
Create a Harvest project after a kickoff is marked ready
Use a designated reaction on a confirmed Slack kickoff to signal project setup in Harvest.

Four ways to start an automation.
A trigger is the event that kicks a workflow off. Notis supports four kinds: an event in a connected app, an inbound webhook, a recurring schedule, and soon, your own database.
Integration triggers
Fire when something happens inside a connected app. New Notion page, Stripe charge, Linear issue: any of 1,000+ apps can start a workflow.
Webhook triggers
A unique URL per workflow. Anything that can send an HTTP POST can start an automation, including no-code tools that speak webhooks.
Recurring triggers
Cron-style schedules run a workflow on the clock. Daily standups, hourly syncs, business-hours-only digests: the workhorse of Notis.
Database triggers
Watch a row, query, or threshold in your own database and fire the moment the data changes. Row inserted, value crosses a limit, query starts matching.
Classic automation breaks. AI adapts.
Same triggers and actions, smarter middle. AI handles the fuzziness that breaks traditional Zapier-style workflows the moment a field gets renamed.
Describe it. Notis builds it.
Skip the visual builder. Tell Notis what you want, in plain English. It writes the workflow, you review and deploy.
