Custom GPT vs AI agent: which does your business need?
Compare custom GPTs and AI agents by capabilities, cost drivers, risk, and use case so you can choose the right AI solution for your business.
Hello, and welcome to Techslik.
We build AI agents that do the real work, and apps people love to use.
Techslik is a small AI and product studio that builds AI agents that do real work, voice agents, custom GPTs, mobile apps and websites for growing businesses. Our agents answer customers, update your systems and book the meetings, and they can even pick up and talk. Try talking to one.

See it in action
Watch it do the work.
Short scenes from the kind of systems we build, from agents that work across your tools to apps in your pocket. Sit back and watch, or jump to one.
A customer writes in.
An illustrative example. Yours would be built around your own tools, data, and customers.
Support inbox
Transcript of the five demo scenes.
Scene 1: The AI agent
A customer writes in. It works across your tools. Anything sensitive waits for a person. Then it replies, job done. That’s an AI agent.
- The customer writes
- “Hi! I was charged twice for order #1842. Also, I’ve moved: can it go to 22 Park Lane?”
- The AI agent opens your tools
- CRM, Orders, Billing, Email
- In CRM
- Customer: Looking up…, then Verified. Matched by email.
- In Orders
- Ship to: 14 Mill Road, then 22 Park Lane. #1842, not shipped yet.
- In Billing
- Charges: $49.00 × 2, then Duplicate found. Refund needs approval. After approval: Refunded $49.00. Approved by Maya.
- In Email
- Confirmation: Not sent, then Sent. To the customer.
- Needs approval
- Refund the duplicate charge, $49.00. Waiting for a person to approve. Button: Approve.
- A person approves
- Approved. Approved by Maya, support lead.
- The agent replies
- “Sorted! Order #1842 now ships to 22 Park Lane, and the extra $49.00 has been refunded. A confirmation email is on its way.”
- Notifications
- Address updated. Refund approved by a person. Every step logged.
AI agents: Routine requests, handled.
Scene 2: The voice agent
Someone calls in. It listens, and talks back. Checks the calendar mid-sentence. Booked. No hold music. That’s a voice agent.
- The call
- Incoming call. Ringing… On call.
- The conversation
- Agent: “Hi, thanks for calling! How can I help today?” Caller: “Do you have anything free on Thursday afternoon? I’d like a consultation.” Agent: “Let me check Thursday for you…” Agent: “3 pm is free. Shall I book it for you?” Caller: “Yes, please!” Agent: “Done! You’ll get a text with the details.”
- Checking the calendar…
- Calendar, Thursday: 2:00 PM Busy, 3:00 PM Free, 4:30 PM Busy.
- Booked
- Consultation, Thursday, 3:00 PM. Confirmation sent by text.
- Notifications
- Answered straight away. Checked the live calendar. Confirmation sent by text.
Voice agents: Your phone, answered.
Scene 3: The team assistant
A teammate has a question. It reads only what’s approved. Answers in seconds. And shows where it came from. That’s a custom GPT.
- Question from Sara, sales team
- “What’s our refund policy if a customer cancels an annual plan after 30 days?”
- Checking approved company sources
- Refund policy v3.pdf, Billing FAQ, Pricing handbook
- The assistant answers
- “After 30 days, annual plans get a prorated refund for the unused months, minus a 10% admin fee. Access continues until the end of the current month.”
- Sources cited
- Refund policy v3.pdf, section 4.2; Billing FAQ, “Cancelling annual plans”
- Notifications
- 3 sources checked. Every answer cited.
Custom GPTs: Your knowledge, on tap.
Scene 4: The mobile app
An idea in your pocket. Designed for thumbs, not mice. Notifications people want. One app, iPhone and Android. That’s a mobile app.
- The idea
- A wireframe sketch of the app’s first screen.
- Design system
- Colour, type and spacing, set once. Applied to every screen.
- Home screen
- Good morning. Your week. Next up: Pilates, Thu · 6:30 PM. Yoga class, Tue · 7:00 AM. Spin, Fri · 12:00 PM. Swim session, Sat · 9:00 AM.
- Class screen
- Yoga class, Tue · 7:00 AM · 60 min. Button: “Book a spot”, then “Booked”.
- Notification
- Your app, now: “Yoga class tomorrow at 7:00 AM. See you there!”
- Screens
- Home, Class details, Booking, Reminders
- Ships to
- iPhone and Android
- Notifications
- One design system. Booked in two taps.
Mobile apps: Apps people keep.
Scene 5: The website
Busy. Unclear. Easy to leave. We cut it back to what matters. Now people get it, and get in touch. That’s a website that works.
- Before
- A crowded page with 11 menu links, the headline “WELCOME TO OUR WEBSITE!!! We are a leading provider of innovative synergistic end-to-end solutions”, and 4 competing buttons: Click here, Learn more, Read more, Download.
- After
- One clear headline, “Bookkeeping that’s done before you ask.”, and one button: “Book a free call”.
- The result
- A clear message in five seconds. Fast on every device. One obvious next step.
- Notifications
- One clear message. One obvious next step.
Websites: A site that explains itself.

- Passes your details to the team

How we work
What working with us feels like.
Clear steps, visible progress, and no long silences. You always know what we’re doing and why.
A real conversation
You tell us what’s slowing you down. We ask plenty of questions about the work, the people, and what a better week would look like. No sales script.
A plan you can follow
You get a plain-language recommendation: what to build first, how it will work, and how we’ll know it’s helping, before you commit to anything.
Built in the open
We deliver in small, working pieces you can try. You’re involved in the decisions that matter and always know what’s happening.
Launch, then improve
We launch carefully, watch how it performs with real people, and keep refining it with you as your needs grow.
“Useful beats impressive.”
A note from our founder
I started Techslik because I kept seeing the same thing: businesses excited about AI, then stuck with demos that never made it into real work.
So we do it differently. We start with your workflow, not the technology. We keep things simple enough for your team to trust. And we stay close, so you always know who’s building your product and why.
Mubashir Nasir
Founder & CEO, Techslik
In our clients’ words
People we’ve worked with.
5.0 from 105 public reviews
“Professional, communicative, polite, quick to act, and understanding.”
“Everything runs smoothly, the tone and structure are spot-on.”
“Will definitely work with him again!”

Where AI agents create real business value, what makes them reliable, and a practical, low-risk way to introduce them into your operations.
Questions
Things people usually ask.
Something else on your mind? Just ask us.
Can I try one of your AI agents?
Yes, right now. Slikie, the assistant on this website, is one of ours. Chat with it, or start a voice call and talk to it: ask about our work, or have it book a call with the team.
Do you build mobile apps too?
Yes. We design and build iOS and Android apps, together with the backend, admin tools and AI features they need, so the whole product is built as one.
Do I need to understand AI to work with you?
Not at all. You know your business; we handle the technical side. We explain every decision in plain language, and nothing gets built until you’re comfortable with how it will work.
What’s the difference between an AI agent and a custom GPT?
A custom GPT answers questions using your knowledge. An AI agent goes a step further and takes actions in your tools, like updating an order or filing a document. We’ve written a full comparison of custom GPTs and AI agents on our blog if you’d like the detail.
Is our data safe?
We connect only the information a system genuinely needs, limit what it’s allowed to do, keep a record of important actions, and keep people in the loop for sensitive decisions.
How much does a project cost?
It depends on the scope, so we don’t quote blind. After a first conversation you’ll get a clear recommendation and scope for a focused first release, and you decide from there.
Do you work with small businesses?
Yes. Many of our projects start small: one workflow, done properly. It’s the most reliable way to get real value from AI without a big upfront risk.
Who will I work with?
You’ll work directly with Mubashir Nasir (Founder & CEO) and Muddasir Ali (Chief Operating Officer), the people building your project. No account managers, no handoffs.
How quickly do you reply?
Usually within 1–2 business days. You don’t need a spec to get in touch: a few honest sentences about what’s slowing you down are enough to start.
Do you work with international clients?
Yes. We work with teams worldwide. Wherever you’re based, you work directly with the people building your project, from the first conversation to launch.

Tell us what’s slowing you down.
A few honest sentences are enough to start. We’ll reply with thoughtful questions and, when it makes sense, a clear first step.
