Frequently asked questions
Slack AI uses the discussions and information that are already in Slack to power a secure experience tailored to you and your organisation:
- Summarise long conversations
- Find answers to questions
- Get a daily recap of less important channels
Slack AI runs on Slack’s trusted infrastructure, and upholds the security practices and compliance standards that customers expect from Slack itself. Slack does not share customer data with large language model (LLM) providers and does not use customer data to train LLMs. Visit our Help Centre for more details.
Our large language models are hosted directly within Slack’s AWS virtual private cloud, ensuring that your data remains in-house.
You can use a credit card to pay for any subscription. If you choose to pay annually, you may be eligible to be invoiced and pay by ACH or bank transfer. Visit our Help Centre for more details, or contact us to start the process.
If you choose to pay by credit card, you’ll see the first credit card charge from Slack on the day that you purchase a paid subscription. Here are some other times when you’ll see charges:
- On your monthly renewal date if you pay monthly.
- On your annual renewal date if you pay annually.
- On the last day of the month if you pay annually and there’s an outstanding balance for adding new members.
You can change billing cycles or switch to invoicing at any time. Learn more about managing billing details here.
At Slack, we believe that you should only be billed for what you use. Members who take an action in Slack at any time within a 28-day period will be considered active for billing purposes. If someone that you’ve already paid for becomes inactive, we’ll add a prorated credit to your account for the unused time.
You’ll be charged a prorated amount for new team members for the remainder of the current billing period.
As an example, suppose your team is on the Pro subscription, which costs $8.75 USD per active user per month (when billed monthly). You add a new member ten days into your billing period, with 20 days remaining in the month. The per-day cost for each user is $8.75 USD divided by 30, so we’ll make a one-time charge of $5.83 USD ($8.75 USD divided by 30 days times 20 days) to the credit card on file.
For a detailed overview of our billing model and how your subscription term affects when you will be billed, visit the Help Centre.
