Connect Simma to Perplexity

Perplexity can use Simma as a custom connector. Once it is added, an athlete gets their own training and a coach gets their squad, with the same reads, writes and safety gates as in Claude and ChatGPT.

Simma is not in Perplexity's own connector list, so you add it by address. It takes a couple of minutes, and you do not need a Simma account first. Connecting creates one.

What you need

A paid Perplexity plan: Pro, Max or Enterprise. The free plan cannot add custom connectors. On Enterprise, an admin may first need to allow members to add custom connectors.

Step by step

Open Perplexity's connectors. Go to Settings → Connectors and choose to add a custom connector.
Paste Simma's address:
```
https://mcp.getsimma.com/mcp
```
Choose OAuth, and leave Client ID and Client Secret empty. Simma registers the client itself.
Sign in, or sign up. Perplexity opens Simma's sign-in page. If you already use Simma, sign in with that email and password. If not, choose sign up on the same page: an email, a password, and the code Simma emails you to confirm it.
Say who you are. New accounts get one short screen: I coach athletes, or I train. A coach enters their name and, optionally, the business name athletes will see. An athlete enters their name, then can link Garmin on the spot. Turn on Historical data on Garmin's page so the last sixteen weeks load straight away.
Back to Perplexity. Garmin asks for your OK before your watch data goes to an AI assistant, so if Simma asks whether Perplexity may read your training, say yes. The last button returns you to Perplexity, signed in.

Your first questions

If you're an athlete:

"How is my training going?"

"Walk me through my last long ride."

"Am I pacing my swims more evenly than I was?"

If you're a coach:

"Who in my squad needs attention this week?"

"Give me the full picture on Sarah before I write to her."

Perplexity picks the tools; you never call them by name. If it does not reach for Simma on its own, name it in the question. For what an athlete can ask, see Ask Your Assistant About Your Training; for a coach, Every Simma Connector Tool, and What to Ask For.

Sending a message

The one action that is never silent is sending a message. Before a coach's draft goes to an athlete, or an athlete's message goes to their coach, Simma asks for the full text to be confirmed. If that prompt is shown and then fails, nothing is sent.

Two privacy settings

Simma's, for your training data. Sharing with Perplexity is its own switch, separate from Claude or ChatGPT. Turn it off or on any time in Connections & Sharing in the Simma web app. See Control What Your Assistant Can See.
Perplexity's, for your conversations. Whether Perplexity trains on your Perplexity chats is your choice in Perplexity, not Simma's: open the menu at the bottom left, then All settings → Preferences → AI data retention. It is on by default.

Who can see what

Your conversation with Perplexity stays between you and Perplexity. Simma sees requests for data, never the words around them. The only thing that reaches another person is a message you deliberately send.

Perplexity processes your conversation under its own terms. An athlete without a coach of their own is attached to Simma's house coach account, which can read their training data as any coach can; see the privacy policy.

If something doesn't work

There is no option to add a custom connector. Check your plan: the free plan does not have it. On Enterprise, ask your admin to allow members to add custom connectors.
Perplexity asks for a Client ID or Secret. Leave both empty and continue; Simma registers the client itself. If it will not go on without them, tell us.
The confirmation code didn't arrive. Check the spam folder; the sender is Simma. The code is good for a short while, and the sign-up page can send another.
Connected, but every question fails. Remove the connector and add it again to refresh the sign-in. If it persists, tell us which question you asked and the error text.
