# AI support agent or shared inbox: what changes for a SaaS team

In a shared inbox every customer message goes to a person. An AI support agent such as Replai answers the routine questions from your documentation and passes the rest to the same people. The difference is who writes the first reply, and how often your team stops building to answer questions the docs already cover.

## Side by side

The table compares a shared inbox, where teammates write every reply, with Replai on the questions that decide the choice for a small SaaS team: who replies first, where answers come from, what happens outside working hours, how a person gets involved and what it costs.

**Shared inbox compared with Replai**

|  | Shared inbox | Replai |
| --- | --- | --- |
| First reply | A teammate | The Agent, or a draft a teammate approves in draft mode |
| Where answers come from | Memory, saved replies, searching the docs | Your published knowledge sources and rules |
| Outside working hours | Messages wait until someone is back | Questions your knowledge covers get an answer; the rest wait for your team |
| The same question again | Answered by hand each time | Answered from the same source; the Gaps list shows what is missing |
| Reaching a person | Every message already reaches a person | On request, when it cannot answer, or when the customer is frustrated, with the history |
| LINE group chats | Someone watches each group | A group mode decides when it speaks: Silent, Mention Only, Keyword or Smart Reply |
| Cost | Team time | A monthly plan with a conversation allowance, see [pricing](https://re-plai.com/en/pricing) |

## When a shared inbox is enough

If a handful of messages arrive each week, most questions concern one customer’s account, or every reply needs a judgment call, people answering directly is the simpler choice. Replai’s draft mode sits in between: teammates still send every reply, but start from a draft written from your documentation.

## When an AI support agent helps

An AI support agent pays off when the same questions keep arriving, when the answers already exist in your docs or help center, and when customers write outside your working hours. It works best when one person on the team owns the knowledge and reviews the Gaps list regularly.

## Moving from an inbox to Replai

Start in draft mode on one channel. Your team keeps sending every reply while the drafts show how well the knowledge covers real questions. When drafts rarely need edits, let the Agent answer first and hand off when needed. Customers keep writing on the same channel throughout.

1. Add the documents and pages your team already pastes into replies.
2. Save the questions you get most often as tests.
3. Connect one channel with the Agent in “People answer, it only drafts” mode.
4. Approve, edit or reject drafts in the inbox for a week or two.
5. When drafts rarely need edits, switch to “It answers, hands off when needed”.
6. Check the Gaps list and add the answers that are missing.
