What changes at the studio with an AI agent?

What does a conversation handled by the AI look like?
Example conversation
Studio AI agent
Customer: How much does Russian volume cost?
AI agent: Russian volume costs your price.
Customer: How often do I need maintenance?
AI agent: Maintenance is at an interval of your timeframe. I'll reach out when it's time.
Is an AI agent or manual customer service better for lash studios?
The agent wins on repetitive tasks, and the person keeps winning on what takes judgment. With manual service someone at the studio has to stop what they are doing; with the CertuAI agent the answer goes out on its own and you join the conversation when you want.
| Aspect | The manual way | With the CertuAI agent |
|---|---|---|
| Price of classic, hybrid and volume lashes | Only answered when you put the tweezers down | Answered right away, technique by technique, with the table time included |
| Length of the application | Client books thinking it takes half an hour | The agent states the procedure time before locking in the slot |
| Maintenance | Only happens if the client remembers on her own | The agent reaches out at the interval you set |
| Squeezing someone in on top of a long volume set | A wrong booking delays the rest of the day | The agent only offers windows that fit that technique |
| Volume set cancelled at the last minute | Two or three hours of table time sitting idle in the middle of the day | Confirmation the day before gives the block back to the schedule in time |
What does the WhatsApp agent do for lash studios?
It does the customer service that is yours today. You teach the business once in the Brain, CertuAI's knowledge base, and the agent answers clients your way, with your rules.
Price and table time for each technique
Classic, hybrid, Brazilian volume, Russian volume and mega volume, each with the price and length you set.
A schedule window the size of the technique
A volume set doesn't fit in a maintenance slot. The agent only offers times that fit the requested technique.
Maintenance before the gaps show up
The agent calls the client back at the interval you set, while it can still be maintained and doesn't need a full new application.
Maintenance is not a new application
Once the time limit you set has passed, the agent already offers the price and time of a full application, so the client doesn't find out in the chair.
Care for the first hours
No water, no steam, no sleeping face down: your instructions go out in writing right after the appointment.
What questions do clients send on WhatsApp?
They are always the same, and the agent answers each one on its own. These everyday studio messages no longer depend on you having your phone in hand.
How does the agent start answering at the studio?
In three steps, on the same day. No installation, no code and no changing the number clients already know.
Teach your business
In one conversation, you explain services, prices, hours and rules, as you would to a new employee.
How much does an AI agent on WhatsApp cost for lash studios?
The Start plan costs US$ 75 per month and already includes the WhatsApp agent, your business's Brain, the CRM, automatic follow-up and the AI assistants, which come with every paid plan. Pro costs US$ 120 per month and adds the landing page, the wallet and 10 people on the team instead of 5. No lock-in contract and no setup fee.
Get started now
Create my agentWhat needs to be ready before turning the agent on at the studio?
The agent answers what is written, and nothing beyond that. Have these points defined before you connect WhatsApp.
- The price list with the price and table time of each technique: classic, hybrid, Brazilian volume, Russian volume and mega volume
- The price and time for maintenance, kept separate from a new application, and after how many days it stops being maintenance
- What you ask for beforehand: arriving with no eye makeup, no lashes from another studio and no contact lenses
- The care for the first hours and what the client should avoid during the week
- The cases you don't take or that call for an assessment first, such as glue allergy and very fragile natural lashes
- The lateness tolerance, because a late client pushes an entire volume set out of the day
Whether the agent can lock in a Russian volume time on its own or whether a long technique goes through you before entering the schedule.
The most common mistake: Registering maintenance and a new application with the same table time. Maintenance takes under an hour, the application takes twice that, and a schedule built on the smaller block delays every client of the day. Read how to fix this.
Frequently asked questions from lash studios
Can the agent explain the difference between the techniques?
Yes, the way you write it in the Brain. It repeats your explanation, not a generic answer from the internet.
Can I stop someone being squeezed in on top of a Russian volume set?
Yes. You set the length of each technique and the agent only offers windows that fit.
Does it tell maintenance apart from a new application?
Yes, by the time limit you set. Past that limit it already answers with the price and time of a full application, and the schedule reserves the larger block.
The client says she is allergic to the glue. Does it book anyway?
Only if you want it to. You list the cases that call for an assessment first, and the agent holds the booking and passes the conversation to you.
In what other fields does the CertuAI agent work?
In any business that serves customers on WhatsApp, because the Brain is written by you. These fields have a day-to-day closest to yours.
