How it works
Zeptap is a Mac app that gives your AI agent your real iPhone, so it works in the apps and accounts you already use.
Plug your iPhone into your Mac. Your agent can now see the screen and tap, swipe and type.
Give it the job and the facts. For example, your price list, sizes and shipping policy.
It reads each comment and DM. Price questions get prices, link requests get the link, and compliments get left alone.
It flags what needs you. Complaints and anything it can’t answer go on a list, and it asks before the first message to someone new.
You watch from your Mac. Every reply shows as it’s typed, and you can stop it at any moment.
Under a Reel, how much in M? gets $48, and it runs true to size from your price list. obsessed 😍 gets no reply. My order never came goes on your list for you.
Comment and DM jobs your agent can take on
Each job below is a single request to your agent; start with the one that costs you the most time.
Comment to DM
Someone comments “link.” Your agent DMs the right product link and says so under their comment.
See comment-to-DM without ManyChatUnanswered questions
It checks your DMs, message requests and Story replies, and answers every question that never got a reply.
Screenshot orders
A customer sends a screenshot. Your agent finds the item in your catalog and replies with the price and link.
WhatsApp Business auto reply
Replies built from your catalog and price list, written for each customer’s question.
TikTok comments, buyers first
It answers the “how much?” and “where do I buy?” comments before anything else.
Prompts to copy
These prompts work as written: start with one post, and once the replies sound like you, give it the whole inbox.
Chat · your iPhoneReply to every comment on my latest Reel that asks about price, sizing or shipping. Use the price list in my Notes app. Leave compliments and emojis alone.
Go through my Instagram DMs and message requests. Answer anyone who asked a question this week and never got a reply.
DM the product link to everyone who commented “link” on today’s post, once each, then reply “Sent you a DM!” under their comment.
Show 3 more prompts
Answer the replies to yesterday’s Story. If someone asks about stock, check our inventory sheet in Google Sheets before you reply.
Open TikTok and reply to the questions on my last three videos. Skip trolls and add any complaint to a list for me.
Check Instagram, TikTok and WhatsApp Business for this week’s customer questions. Answer each in the customer’s language and list what you couldn’t answer.
ManyChat, LinkDM and other auto reply tools vs. your agent
DM tools like ManyChat send a prepared message when a rule fires; your agent reads each message and writes a reply.
They run on Meta’s official Instagram API. That API only works with professional (Business or Creator) accounts, and it allows a single private reply to a commenter, within 7 days of the comment.
What each one does
| Instagram’s built-in tools | Keyword DM tools (keyword flows) | Your agent with Zeptap | |
|---|---|---|---|
| Accounts | Business or Creator | Business or Creator (Meta API) | Business, Creator or personal, in the app |
| What triggers a reply | First message, away hours, a keyword you set | A keyword you set (AI add-ons can match intent) | The agent reads what each person asked |
| The reply | Saved text, or Meta’s AI reply (some creators) | Your template; AI add-ons can vary wording | Written for each person, from your facts |
| Comment to DM | Comment to message automation in Meta Business Suite | One private reply per comment, within 7 days | Comments you point it to, sent as a normal DM (no API 7-day window) |
| TikTok and WhatsApp Business | Separate settings in each app | Varies by tool | Same agent, in each app |
| When it runs | Always on | Always on, in seconds | When you ask, done in minutes |
What each one costs
DM tools price by contacts or Instagram accounts; Zeptap prices by iPhone. Cheapest paid plans, checked October 14, 2026:
| Tool | Cheapest paid plan | Billed | Priced by |
|---|---|---|---|
| ManyChat | Essential, $14/mo for 250 active contacts | Annually ($168/yr) | Active contacts |
| LinkDM | Pro, $19/mo for 3 Instagram accounts, 25,000 DMs | Monthly | Accounts and DMs |
| CreatorFlow | Pro, $15/mo for 2 Instagram accounts, 5,000 DMs ($12/mo annually) | Monthly or annually | Accounts and DMs |
| Inrō | Pro, from €12.99/mo for 500+ active contacts | Monthly | Active contacts, auto-scaling |
| Chatfuel | Business, $18/mo | Annually ($216/yr) | Usage limits on a separate page |
| Zeptap | $25/mo, or $99 once for one iPhone | Monthly or one-time | iPhones; no per-contact, per-account or per-DM fees |
How the cost compares as you grow:
- One account: a DM tool costs $12–19 a month against Zeptap’s $25, but $99 once costs less than 6–9 months of one.
- A growing audience: contact-priced plans rise as more people message you, every month.
- Many accounts: Zeptap Lifetime Plus is $149 once for up to five iPhones and 20–30 accounts.
Your AI plan is separate, and you may already pay for it.
When a keyword tool is the better pick
A keyword tool is the right choice when every DM must land within seconds, around the clock.
- Use a keyword tool for a “comment GUIDE” Reel that needs replies at 3 a.m.
- Use your agent for every question the keyword never caught, on any account you run.
- Run both if you want. Zeptap has no built-in scheduler: your agent works when you run it, or when your own automation starts it.
You stay in control
Your agent works on your iPhone while you watch, inside the job you gave it.
Watch every reply as it’s typed
Your iPhone’s screen is live on your Mac, and you can stop the agent at any moment.
It’s built to ask before the risky stuff
It’s designed to stop and ask before it messages someone new, buys or pays.
Your passcode never leaves your Mac
It sits on your Mac, and the agent never sees it.
Your screen never touches Zeptap’s servers
Screenshots go only to the AI provider you chose, under your own plan.
Give it the facts
Share your prices, sizes and policies, and tell it to list anything they don’t cover. You can read every reply as it goes.
