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 that handles the busywork, and websites people love to use.
Techslik is a small AI and web studio that builds AI agents, custom GPTs, and websites for growing businesses. We help teams answer customers faster, stop copying data between tools, and put their knowledge to work, with systems they actually trust.

Sound familiar?
If any of this sounds like your week, we should talk.
Most people come to us with a feeling, not a spec. Pick the one that sounds most like you.
What we’d build
An AI support agent
It answers from your own knowledge base, handles routine requests like order checks and updates, and passes anything unusual to a person, with the full context attached.
AI agentsWhat changes
Your team spends its time on the conversations that genuinely need a human.

What changes
Your team spends its time on the conversations that genuinely need a human.
What we’d build
A workflow agent
Connected to the tools you already use, it reads, checks, and moves information between them, and keeps a clear record of every step it took.
What changes
Hours of repetitive admin become a quick review.
What we’d build
A custom GPT
An assistant grounded in your approved documents, policies, and products. It answers in your tone and shows where each answer came from.
What changes
Anyone on the team can get a reliable answer in seconds.
What we’d build
A clearer website
We rebuild the story around what your customers need to understand and do, then make it fast, accessible, and easy to keep up to date.
What changes
Visitors understand you quickly, and more of them get in touch.
What we’d build
A focused first step
We map one workflow with you, find the smallest change that would make a real difference, and give you a plain-language plan before anything gets built.
What changes
You stop guessing and start with something you can measure.
See it in action
Watch it do the work.
Three short scenes from the kind of systems we build. 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 three demo scenes.
Scene 1: The support agent
A customer writes in. Your agent gets to work. It replies, in your voice. Your team stays in charge. That’s an AI agent.
- The customer writes
- “Hi! Can you change the delivery address on order #1842? I’ve just moved to 22 Park Lane.”
- What the agent does
- Verified the customer. Found order #1842, not shipped yet. Updated the delivery address. Logged the change in the CRM.
- The agent replies
- “All done! Order #1842 will now go to 22 Park Lane. A confirmation email is on its way.”
- Notifications
- Address updated. Logged in your CRM. Unusual requests go to a person.
AI agents: Routine requests, handled.
Scene 2: 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 3: 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.

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

The future of AI agents: transforming business operations
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.
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.
