AI interaction design
Building an editing-first model for users with no prompt skills
Systems thinking
Turning a single feature into a reusable pattern across four surfaces
Background
The setup
Superfone is a UCaaS product for India's small businesses. The kind of business run by one or two people wearing every hat. In late 2025, we began bringing AI into the product. The caller tune was the first feature it touched.
Who
Small business owners across India : clinics, salons, coaching classes, retail shops. AI-curious. AI-unfamiliar.
Why
These users had only ever used AI for entertainment (ChatGPT, Meta AI). Never for work. We didn't yet know how they'd respond; would they trust it, engage with it, break it?
What
Introduce AI to Superfone users for the first time. Build the proving ground for every AI feature that would follow.
Where
The caller tune — a low-stakes, low-engagement feature, deliberately chosen so AI-driven activity was pure upside.
When
Setup moment for new users. In-app launch promotion for existing ones.
How
Low entry requirement. Connect social media and website. AI handles the rest.
Superfone caller tune is a short greeting the user’s customer hears when they call the business.
Current state
62% of users never customised their caller tune
A generic caller tune is automatically setup by default when a new user is registered : “Thank you for calling [business name]. Please hold.”
Before AI, customizing it was simple: type a message, hit publish. A text-to-speech engine read it aloud.

They didn't know what good looked like
Users didn't know what to write, what tone to strike, what details to include. So they wrote nothing.
They didn't see the value
Users didn't realise a good caller tune builds trust, signals professionalism, or can be used to announce offers, hours, or news.
They didn't have the writing skills
Even users who wanted to customize struggled to write a polished business greeting in English, in their native language, within the character limit. Most gave up.
Solution
Let AI do what users couldn't
Write polished, brand-specific business communication by pulling from the user's website, Instagram, and Google Maps, AI generated a caller tune that named the business, hinted at its personality, and sounded professional.

The risk
AI alone doesn’t fix passive acceptance
We made generating the caller tune easy, but shaping it isn't. This replaces one form of disengagement with another, just enhanced by technology.
But the moment they tried to make it theirs to add a detail, change a phrase, switch the language; the skill problem came back.
⚠️ The user's behavior would be exactly the same as before. Set it once, never come back. Just dressed up in better tech.
Here's what would happen with AI: the user would see a great-looking AI-generated caller tune. They'd hesitate to edit it. Why would they? They couldn't write better than what AI just gave them. So they'd publish whatever AI made.
Ultimately, their writing skills will determine if they complete the customisation, and most likely, they won’t.
The AI was solving the entry problem. It wasn't solving the engagement problem.
And without engagement, there was no ownership.
Without ownership, no pride.
Without pride, the same feature gathering dust on most users' numbers.
Reframing the problem
How do we get users to engage with the AI's output without making them work too hard?
Users needed to feel pride from shaping the output; the IKEA effect.
But they couldn’t write well enough to shape it. The skill barrier was still there.
They couldn't talk to AI. Users have never experienced AI as a business tool. No prompt skills
Solution
3 possible directions
A
Conversational interface
The industry default. A chat interface with a prompt box, a message thread, a back-and-forth between user and model. The user describes what they want, AI generates, the user iterates.
Pros:
Full creative control
Maximum flexibility
High involvement
Cons:
Requires prompt skills
Free-form prompts would invite outputs we hadn't designed for.
Chat needs threads, history, regenerate, clarification turns.
B
Free-text editing
Show the AI-generated caller tune in a plain textbox. Let users edit freely.
Pros:
Low UI surface area.
Familiar pattern (the pre-AI feature was already a textbox).
Cons:
This was already the trap I'd just identified.
User would still feel their skills of editing the AI generated output is insufficient
C
A combined approach
Give users the AI-generated draft, and bring AI back into the editing flow.
Pros:
Accepts messy inputs
Users feel more confident when they see ‘Improve it’ button
Solves ‘more options’ problem
AI improves the content within the guardrails set
Cons:
No version history
No inputs of tone or emotion. Only information gathered.
Most AI products in 2025 default to chat. Option C wasn't a standard. But for our users, it was the only direction that solved all three constraints : involvement, low skill requirement, no conversation.
Creation of AI Assisted Communication Module (AICM)
A textbox and two AI-powered buttons. Accepts messy input in any language, any length, any combination.
Not ‘Edit’ but ‘Improve it’
This single button absorbs every imperfection the user might write. Awkward phrasing, length issues, mixed-language cleanup, off-tone output. It carries a promise, whatever you wrote will get better.
‘Fit content’
Over-limit characters highlight in red. One tap and AI compresses the message without changing meaning.
‘More ideas’
Limited variations based on the current text to avoid choice paralysis. Keeps the experience bounded, token costs predictable.
Voice and personality, separated from text
Voice selection sat next to the text, not inside it. Tone changes happened by switching voice, not by re-prompting.
What we skipped
Undo, history, version saving
We didn't save AI iterations. We didn't keep version history. If the user doesn't like the AI's changes, they just exit without saving. Nothing's lost because nothing was committed. This kept the editing flow feeling low-stakes and exploratory
Outcome
From default to brand identity
The feature shipped in 3 weeks. Within the first month, the behavior shift was visible in the data and in user feedback. Users weren't just adopting the feature, they were coming back to it.
Before
After
Customisation rate
24% of users customised the default
72% of users customised the AI output
Active re-engagement
18% of users returned to the feature post-setup
52% returned to refine, update, or republish
Customization triggers
None
Festivals, offers, business hours changes, holidays
67% said “Feels like part of my brand"
The win wasn't that AI did the work for the user. It was that AI made the user feel proud of the work they did.
Surface adoption
From a feature to a system
AICM was built for caller tunes. But the underlying user need — I know what I want to say, help me say it well — wasn't unique to this feature. It showed up across the product. So the module did too.

What changed across surfaces
The prompt. The tone. The character budget. The audience. The language defaults.
What stayed constant
The textbox. Improve it. More ideas. The user's experience of meeting AI.
Why a module, not a feature
When the same interaction works across multiple surfaces, you're no longer designing a feature. You're designing an interaction model that is stable for users to meet AI inside this product.
That's where the value compounds. Every new surface that adopts AICM costs less to design. Users meet AI the same way every time. The product gets a coherent AI personality without each team reinventing the pattern.
Reflection
What this work taught me about designing AI for non-tech users
Many AI business tools today position AI as an assistant, which works for users familiar with it as a coworker. However, our users had only interacted with AI for fun, not considering its use for business or skill development.
To bridge this gap, I redefined AI within Superfone as added intelligence. As a booster that helps users complete tasks faster and better, without the need for conversation. Our users prefer their existing methods and are not looking for disruptive changes or new skills. Therefore, we needed to demonstrate that this AI enhancement was worthwhile.
The experience should not overwhelm users. They shouldn't have to navigate when or how to interact with AI, as each decision adds cognitive load. Instead, I designed AI to perform one specific task well, seamlessly integrated into familiar interfaces. The best AI design minimizes user decisions, providing support only when necessary, allowing users to focus on their work.
