Tab vs Instinct: Which Texting AI Agent Is Better?
Tab and Instinct are the two AI agents people compare most this fall. You text both of them, and both go off and do the job: call the restaurant, book the flight, buy the thing.
The quick answer: Instinct is the stronger agent today. It scores higher on almost every independent test, it runs morning routines on time, and you can call it as well as text it. Tab is the better phone caller and the more careful one with your money, but it fumbles bookings and forgets context. Both are free private betas built for life admin. If the calls that matter are your business calls, and you need an assistant that answers the phone, calls you back on schedule and remembers every caller, Carly does all three today.

Where Instinct wins
- It gets more done. Instinct scores 8 on online tasks and 8 on travel. Tab scores 3 and 5. In one test Tab made three tries at a table for two, by website and by phone, and booked none of them.
- It remembers. Instinct answered a question about a past booking by cross-referencing two emails. Tab kept your name and card across tasks, then booked a Saturday dinner without checking the trip it had planned for that same weekend.
- It runs routines. Instinct’s 7am weekday briefing landed on time both test mornings with the calendar, conflicts and replies owed. Tab has no routine score yet, and its own changelog says a reminder can run late when it is busy with something else.
- You can call it. Instinct takes texts and phone calls. Tab only takes texts.

Where Tab wins
- It is the better caller. Tab scored a 10 on phone calls: it rang the restaurant within a minute and reported back a minute later. Instinct is only now rolling calls out.
- It is careful with money. Tab shows you the item, the total and who gets paid, and charges nothing until you say yes. Your card goes in through a private link the AI cannot read. Tab scored 9 on permissions. Instinct scored 5, because it asks for Gmail, Calendar and Drive with full access and no read-only option.
- It promises not to train on you. Tab’s co-founder told TechCrunch your data is never used to train AI. Instinct trains on your data by default unless you opt out.

What neither one does
Both are personal errand-runners. Neither one answers a phone line for you, so a customer, a client or a lead who calls still gets your voicemail. Neither keeps a record of the people you deal with: who called, what they wanted, what you promised. And both run on websites that push back, so a booking can stall at the last step.
That is the gap Carly fills.
Carly: calls both ways, and it remembers everyone
Carly is an AI assistant for your work: email, calendar and phone. It is reliable and endlessly customizable. You set the rules once in plain English and it follows them the same way every time.
- It answers your calls. Carly picks up your business line 24/7, or only the calls you miss, in English or Spanish. It books callers on your real calendar while they are on the line.
- It knows who is calling. Carly looks up every caller in your CRM, greets the people you know by name, and logs every call, transcript and text to their record.
- It calls you. Ask “call me every weekday at 8am with my day” and it does. Don’t pick up and you get the rundown by email.
- You can call it. Ring your Carly number from your own phone and you get your own assistant: “Hi Josh, what can I do?”
- It calls people for you, writes up what happened, and texts back every call you miss.
- It lives where you already chat. Add the Carly plugin to ChatGPT or the Carly connector to Claude, Grok Bot, Meta Muse or Perplexity, then place calls and watch them live from the chat.
Carly connects to thousands of apps, and every call can start a workflow. Free Zapier-style workflows; AI agents from $35/month. Get started.
Which should you pick?
- Pick Instinct if you have an invite and want the most capable errand-runner for travel, bookings and personal email.
- Pick Tab if you want an agent that calls businesses well and never spends without asking.
- Pick Carly if your phone rings for work. It answers, calls back, calls you, and keeps every caller on file.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
