AI Assist in the reply box

AI Assist helps you write replies inside the conversation reply box: fix the spelling and grammar of a draft, make it clearer and more professional, change its tone, translate it into the customer's language, summarize the conversation, or draft a suggested reply. You can then refine the result with an instruction such as "shorter" or "more polite".

It runs on your own AI key

AI Assist is available on every plan, and it always uses your own AI provider key; there is no shared default for it. The same key can also power the AI Agent when your plan includes it.

Add your key

1. In STS Connect, open AI Agent from the side menu.
2. Under AI Provider, choose a provider: OpenAI, GLM / Z.ai, DeepSeek, or Custom for any OpenAI-compatible service. Choosing one fills in its address and a suggested model.
3. Paste the API key you created with that provider, and check the Model, for example gpt-4o-mini, glm-4.6 or deepseek-chat.
4. Press Save changes. The key serves the whole workspace, so every agent in the inbox can use AI Assist.

Leave the key field empty on later visits to keep the saved key. Reset to platform AI clears your key; AI Assist then stops working until you add one again.

When something goes wrong

• If your team has not added a key yet, AI Assist in the inbox tells you so and points you to the AI Agent page.
• If the provider rejects the key, or its account runs out of credit, AI Assist stops. The reason is shown on the AI Agent page and emailed to your workspace owners and administrators. Top up the provider account, or save a different key.

Privacy

• Your key is stored encrypted and is never shown again after you save it.
• To produce an answer, the relevant conversation text is sent to the provider of the key you added, and only for that purpose.
• Our logs record usage counts only, never message text. How your provider handles your data is governed by your agreement with them.
