It also adds `/synapse` commands, so leads can check AI adoption and developer insights without leaving Slack. Learn more and install it at [synapse.work/slack](https://synapse.work/slack). ## Support Email **[hi@synheart.ai](mailto:hi@synheart.ai)** for help with the Slack app. You don't need a Synapse account or any other sign-up to contact us. * **Response time:** we reply within 2 business days. * **Include:** your Slack workspace name, the command or channel involved, and what you expected to happen. Screenshots help. * **Security reports:** send them to [security@synheart.ai](mailto:security@synheart.ai). * **Privacy and data requests:** to access, export or delete your data, email [hi@synheart.ai](mailto:hi@synheart.ai). See the [privacy policy](https://synapse.work/privacy-policy). ## Install Slack is connected once for the whole organization, and a Synapse Admin installs it. 1. Sign in at [synapse.synheart.ai](https://synapse.synheart.ai) as a Synapse Admin, or [create an account](https://synapse.synheart.ai/signup). 2. Choose **Add to Slack** on [synapse.work/slack](https://synapse.work/slack), or go to **Admin → Connectors** and connect **Slack**. 3. Slack shows the workspace and every permission Synapse asks for. Review them and choose **Allow**. Slack appears under **Connected** on the [Connectors](https://docs.synheart.ai/synapse/connectors.md) page once it's installed. Slack is included on Synapse Free. ## Use it **Weekly digest.** Under **Teams → Goals & alerts**, turn on **Post to Slack weekly** and choose a channel. Invite `@Synapse` to that channel. See [Weekly digest](https://docs.synheart.ai/synapse/goals-and-alerts.md#weekly-digest). **Goal alerts.** When you create an alert, set **Notify via** to **Slack** and choose a channel. See [Goals & alerts](https://docs.synheart.ai/synapse/goals-and-alerts.md). **Commands.** Type these in any channel Synapse is in: | Command | Does | | - | - | | `/synapse digest` | Shows the full weekly digest | | `/synapse why` | Shows what moved this week | | `/synapse recommend` | Lists the top recommended actions | | `/synapse aei` | Shows AI adoption, delivery and human state, each in its own unit | | `/synapse ask ` | Searches your organization's memory | | `/synapse remember as adr: ` | Saves a decision for people and agents | Team figures go only to Synapse leads and admins who have linked their Slack account under **You → My connections**. If a group is smaller than the privacy floor, Synapse doesn't answer for it and says why. ## What Synapse asks Slack for | Permission | Why | | - | - | | `commands` | Adds the `/synapse` command. | | `chat:write` | Posts the weekly digest, goal alerts and command replies. | | `channels:read`, `groups:read` | Lists channels, so an admin can choose where Synapse posts. | | `channels:history`, `groups:history` | Reads message IDs, authors and times. Reads text only from public channels an admin adds as [knowledge sources](https://docs.synheart.ai/synapse/knowledge-sources.md). | | `users:read` | Shows names instead of user IDs. | | `users:read`, `users:read.email` (user) | Matches the person installing to their Synapse account. | Synapse never reads direct messages, files, or the text of private or shared channels. See [What each source gives Synapse](https://docs.synheart.ai/synapse/connectors.md#what-each-source-gives-synapse). ## Remove it Either of these stops collection: * In Synapse, go to **Admin → Connectors**, open **Slack** and choose **Disconnect**. To delete what Synapse already imported from Slack, tick **Also delete everything Synapse imported**. See [Disconnecting](https://docs.synheart.ai/synapse/connectors.md#disconnecting). * In Slack, remove the Synapse app from your workspace's app settings. If you removed the app in Slack and want the imported data deleted too, email [hi@synheart.ai](mailto:hi@synheart.ai). ## Troubleshooting | Problem | Fix | | - | - | | `/synapse` replies that Slack isn't connected | A Synapse Admin needs to finish installing from **Admin → Connectors**. | | The digest or an alert doesn't post | Invite `@Synapse` to the channel, then choose **Send one now** under **Weekly digest**. | | Commands don't return team figures | Link your Slack account under **You → My connections**. Only leads and admins see team figures. | | Slack is under **Needs attention** | Open it on the Connectors page and choose **Reconnect**. | If none of these fix it, [contact support](#support).
