Short answer
An AI reply generator drafts a response to a customer message in the right length and tone for the channel. This one writes chat, email, social and review replies, uses only the facts in the policy text you paste, and never invents order numbers, discounts or dates. Edit the draft before you send it.
How to use the AI reply generator
- Paste the customer message. Remove details you do not want to share, such as full names or order numbers. The reply will use placeholders where it needs them.
- Pick where you are replying. Chat, email, social media and public reviews each get a different length and structure.
- Say what the reply should do (optional), such as "apologize and offer a replacement".
- Paste your policy or facts (optional). The reply then uses your real refund window, delivery times and rules instead of typical ones.
- Edit before you send. Add the customer's name and one detail only you know.
What changes by channel
| Channel | Length | What matters most |
|---|---|---|
| Live chat | 1 to 3 short sentences | Speed and one clear next step |
| Greeting and 2 to 4 short paragraphs | Complete answer, so no second email is needed | |
| Social media | Under 280 characters | Public tone, no personal data, move to private messages |
| Public review | Under about 120 words | Future customers read it more than the reviewer does |
Why the policy box matters
A model that does not know your rules fills the gap with what is common. "Refunds take 5 to 7 business days" sounds right, but if your policy says 10, the reply just made a promise you will break. When you paste your policy, the generator is told to use only those facts for prices, dates, limits and rules, and to say the team will check anything the policy does not cover. It is also told never to invent order numbers, discounts, dates or links.
This is the same rule that matters for any AI in customer support: answers come from your own content, and when the content is silent, the honest answer is "let me check", not a guess.
A reply structure that works
- Acknowledge. Show you read the message: "I'm sorry your order hasn't arrived yet."
- Answer or act. The fact, the fix or the next step, with a time: "I've asked the carrier to trace it today."
- Set expectations. What happens next and when: "If it isn't found by Friday, we'll send a replacement."
- Close. One line that invites a reply, only if needed.
Choosing the tone
- Friendly for most consumer messages and chats.
- Professional for business customers, legal or billing topics.
- Empathetic when the customer is upset or something went wrong on your side. It leads with the feeling before the fix.
- Concise for quick confirmations and chat.
Replying to reviews
A reply to a public review is written for the next customer who reads it. Thank the reviewer by name if the platform shows it, mention the specific point they raised, say what you changed or what you will do, and offer a private channel to sort out details. Do not argue facts in public, and never post order details or anything that identifies the customer beyond what they shared.
Mistakes to avoid
- Sending the draft without reading it. Check every fact, name and date.
- Quoting policy before showing you understood the problem.
- Promising a time you do not control, such as a carrier delivery date.
- Asking for details the customer already gave in the message.
- Copying the same apology into every reply, so it stops meaning anything.
When to stop writing replies one by one
If you paste the same kind of message every day, save the reply as a template. The canned responses library has 100 to start from. If the same questions keep coming even with templates, the answer probably belongs in your help center, where a customer support chatbot can give it at any hour from your own pages.
Frequently asked questions
How long should a customer service reply be?
Chat: one to three short sentences. Email: a greeting and two to four short paragraphs. Social media: under 280 characters, in public. Review replies: under about 120 words. The generator applies these limits per channel.
Why add my policy text?
Without it, a model guesses your rules, and a guessed refund window or delivery time becomes a promise to the customer. With it, the reply uses only your facts, and says the team will check anything the policy does not cover.
How should I reply to an angry customer?
Acknowledge the problem first, in their words, without blame. Say what you will do and by when. Avoid policy quotes as the first line. Choose the empathetic tone for this.
Should I reply to public reviews?
Yes, to negative ones especially. Thank the customer, address the specific point, offer to continue privately, and never share order or personal details in public.
Is the reply generator free?
Yes. You get 5 free AI runs a day without an account, shared by all our AI tools. What you paste is sent to our AI model to write the reply and is not stored. Remove names and order numbers if you prefer.
