How the AI helps

Less typing.
More solving.

Instant draft replies

Every incoming message arrives with a suggested response, ready to send or edit — no blank-page typing.

On-brand, every time

Suggestions are grounded in your past answers and knowledge base, so the tone and facts match your business.

Human in the loop

Nothing sends automatically. Agents approve, edit, or rewrite — you keep full control of customer-facing replies.

About the AI

What teams ask
about AI replies

Which AI models do you use?+
HelpStack works with OpenAI and Anthropic models. Use our default keys or bring your own for full control over cost and data.
Does it reply automatically?+
Only if you want it to. By default, AI drafts a suggestion and a human approves it before sending. Auto-reply is opt-in.
How does it match our tone?+
Suggestions are grounded in your previous replies and knowledge base, so they sound like your team — not a generic bot.
Is our data used to train models?+
No. Your conversations are used only to generate suggestions for your workspace, never to train shared models.
