UX/UI design services for traditional and AI software
SumatoSoft designs user interfaces and experiences for legacy systems and AI products, from conversational interfaces to approval flows and citation patterns that fit enterprise workflows and support human oversight.
Our UX/UI design services
User behavior research and analysis
We study how users move through a product: where they slow down and what they expect next. For existing systems, we review behavior data. For new products, we conduct interviews and research sessions to inform design decisions based on user needs.
Custom user experience design
We design product experiences around how people think and work. Using design thinking and cognitive psychology, we shape flows that reduce unnecessary effort and support task completion.
UX strategy and design
We connect business goals with user needs and turn them into a structured UX direction. This includes navigation, interaction logic, content hierarchy, and screen purpose. Each part of the interface supports a defined job in the product.
Wireframing and interactive prototyping
We build wireframes to map structure and workflows, then create interactive prototypes, so stakeholders can review logic, layout, and flow. This helps teams catch issues sooner and align on the product before engineering begins.
AI-driven UI and UX design
We design interfaces for copilots, conversational systems, RAG products, and human-in-the-loop workflows. This includes approval patterns, response states, source citation components, fallback flows, and review steps for AI-generated output.
Usability testing
We test how people use the product before launch and during improvement cycles. Through in-person sessions, remote testing, and tools like Lookback.io, we observe user actions and spot hesitation, confusion, and drop-off points. The findings inform design revisions.
One design team for enterprise software and AI products
Some products require dense workflows, structured data, and interfaces that support daily, repetitive work. Others need conversational patterns, review layers, and response states built around AI output. We design both, so we’re able to help when you are modernizing an established system, adding a copilot to legacy software, or building a new AI product from the ground up.

AI product need a different UX model
Traditional business software follows defined logic: a user selects a command, the system returns a known result, and the interface moves to the next state. AI products behave differently. The same request can yield different outputs, response times can vary, and users need interface cues to help them judge whether to rely on what they see.
That changes the role of UX. For AI products, the interface has to show where the answer came from, what the system is doing, when a person should review the output, and what happens when the model cannot complete the task well enough.
We design AI-driven UX around four patterns:
Source-aware answer design
For RAG systems and knowledge tools, we design answer areas that display supporting sources, referenced documents, and retrieved passages in a way that lets users review them without breaking their workflow.
Response-state design
Large language models do not return results instantly in every case. We design streaming states, skeleton screens, progress feedback, and background-task patterns so users understand what the system is doing while they wait.
Fallback and recovery flows
Models can return weak answers, miss context, or fail to retrieve the right document. We design fallback states, retry paths, edit options, and escalation routes so the product continues to support the user when the model’s output is insufficient.
Review and control points
In enterprise products, AI should not operate without oversight in every workflow. We design approval steps, editable outputs, and handoff points that let teams inspect what the system produced before going into production.
When should you involve UX/UI experts?
You should bring in UI/UX experts when:
- You are starting an MVP or validating a product idea,
- Your users are confused, dropping off, or not converting,
- You are scaling the product and need consistency across new features,
- You are modernizing legacy software with usability issues,
- You want to shorten development time by solving product issues at the design stage,
- You are integrating an LLM or RAG system and need a conversational UI that users can trust,
- You need to design a human-in-the-loop dashboard, so your team can review and safely approve autonomous AI actions.
Our UX/UI team helps define how people move through the product, where automation supports the workflow, and where human review should remain. This reduces delivery risk, supports adoption, and gives engineering a stronger starting point.
Why Fortune 500 brands choose our UI/UX design services
Extensive experience & proven results
SumatoSoft has designed and built software since 2012 and delivered more than 350 projects. That experience shapes how we run design work today. We use a structured workflow, reusable patterns, and AI-assisted support to speed up routine work. Our team reviews, edits, and validates every output before it moves forward. This helps us deliver development-ready design faster, with up to x2 shorter turnaround in some projects and about 25% less time spent on UI production on average. The goal is simple: reduce waste, improve usability, and move products into development with less friction.
Skilled, сross-functional team
Our UI/UX designers work alongside business analysts, engineers, and QA specialists from the start. More than 70% of the team are senior professionals, so product logic, technical limits, and implementation needs shape design decisions. We also use AI tools within this workflow to support research synthesis, accelerate exploration, and prepare draft artifacts. The team does not pass those outputs through untouched. Designers review, refine, and align them with business rules, user needs, and system constraints before anything reaches the client or the build team.
User-centered and agile approach
We place real users at the heart of our design process. From early user research and usability testing to iterative prototype feedback, our agile methodology ensures the end product truly resonates with its audience. You will be involved at every step with regular design reviews, transparent progress reports, and close communication. This agile, user-first approach minimizes costly rework and keeps the project on track.
Comprehensive deliverables
We provide complete design deliverables that streamline development. You will receive everything from user persona documents and journey maps to interactive prototypes and full UI style guides. Our deliverables are development-ready, meaning your engineering team (or ours, if you continue with SumatoSoft for implementation) can immediately start building with clear guidance. The result is a smoother hand-off and an end product that faithfully executes the design vision.

Let’s talk about your users, goals, and how better UX can boost conversions.
Designing beyond the chat window
The market is overflowing with interfaces that simply add a chat window to the product. For internal systems, workspaces, and complex corporate processes, this is often insufficient. We design interactions with artificial intelligence to match the task, the user’s role, and the work context.
Command and monitoring dashboards
For autonomous and semi-autonomous systems, we design dashboards that enable users to observe the artificial intelligence’s work and intervene when needed. These interfaces display active processes, task status, progress, success rate, problem areas, event logs, and manual control points.
Voice interfaces
For mobile workers and field teams, we design voice-based scenarios in which artificial intelligence operates through speech, short commands, and visual feedback. In such products, not only are voice responses important, but also on-screen prompts, recognition confirmation, wait states, error correction, and secure action confirmation.
Contextual overlays with hotkeys
In some products, artificial intelligence shouldn’t permanently occupy screen space. For these cases, we design hidden interfaces that are opened with a hotkey and appear only when needed. This allows us to integrate help, search, command generation, data management, and quick actions into the main product without overloading the main interface.

Our UI/UX design portfolio
The system has produced a significant competitive advantage in the industry thanks to SumatoSoft’s well-thought opinions.
They shouldered the burden of constantly updating a project management tool with a high level of detail and were committed to producing the best possible solution.
We tried another company that one of our partners had used but they didn’t work out. I feel that SumatoSoft does a better investigation of what we’re asking for. They tell us how they plan to do a task and ask if that works for us. We chose them because their method worked with us.
SumatoSoft is great in every regard including costs, professionalism, transparency, and willingness to guide. I think they were great advisors early on when we weren’t ready with a fully fleshed idea that could go to market.
They know the business and startup scene as well globally.
The Rivalfox had the pleasure to work with SumatoSoft in building out core portions of our product, and the results really couldn’t have been better.
SumatoSoft provided us with engineering expertise, enthusiasm and great people that were focused on creating quality features quickly.
From the early stages of the project, SumatoSoft demonstrated a proactive attitude, actively seeking opportunities to enhance the solution and anticipate our needs. They consistently took the initiative to address any potential issues, provide timely updates, and offer solutions to challenges that arose during development. This proactiveness greatly contributed to the project’s success and exceeded our expectations.
SumatoSoft is flexible, efficient, and extremely good at planning and being proactive. They have also been very proactive in their approach throughout the project, seeking to understand the needs and the reasons behind them before launching into development, which has been helpful for maintaining direction and consistency, especially because the end client is regularly generating new ideas for added features.
Frequently asked questions
How does UX/UI design for an AI product differ from traditional product design?
In a traditional product, scenarios are often predefined. In an AI interface, we need to consider undefined requests, response latency, model errors, and human review. Therefore, in addition to screens, we design wait states, constraints, source display, and control points.
Do you design ChatGPT-style interfaces for enterprise products?
Yes. We design conversational interfaces, built-in assistants, and sidebars that work seamlessly within your product. They are based on your roles, data, access rights, and workflows, rather than looking like a generic external module.
Can an AI assistant be integrated into an existing enterprise system without a complete redesign?
Yes. In many cases, a complete redesign is not necessary. We can design a sidebar, a contextual widget, a hotkey overlay, or a separate approval screen and integrate this layer into the existing interface.
How do you solve the problem of response latency for a large language model in the interface?
We design the interface so that waiting doesn’t feel like a failure. To achieve this, we use streaming response output, skeleton loaders, intermediate statuses, and scenarios that allow the user to continue working while the model completes the task.
How does interface design help reduce the risk of model errors and improve the system over time?
The interface not only helps display the response but also collects feedback. We implement response evaluation, regeneration, editing before saving, action rejection, and manual review. This helps monitor the outcome and improve the system based on user behavior.
