Copilots, agent consoles, chat and generative tools
AI App and Agent Interface Design Services
Devoq Design is an AI app development company that starts with the interface: copilots inside existing software, chat products, agent consoles, document and image tools, and mobile AI apps. We design input, output, review and control together, and build with your engineers or ours, so the model reaches users in a form they understand and can correct.
AI app development services built around control, clarity and cost
Building an AI app is no longer the hard part; making people comfortable using it is. Users stall at an empty prompt box, distrust answers that cite nothing, get stuck when an agent acts without warning, and abandon products whose bills they cannot predict. We design these moments on purpose: starter prompts and templates that show what is possible, streaming states that explain what the system is doing, plans an agent shows before it acts, edit and undo for every output, and usage visibility that keeps cost understandable. Components are documented in a design system so new AI features ship consistently instead of each team inventing its own chat pattern.
Our Services
Product design and development for AI-native startups, enterprise copilots, developer platforms and consumer AI apps:
Chat and Copilot Interfaces
Prompt entry, context, streaming answers, citations and follow-ups designed for the work a person is actually trying to finish.
Agent Consoles and Approvals
Task plans, step logs, approval gates, pause and rollback so people supervise agents without watching every move.
Generative Creation Tools
Image, text, code and document tools with variations, history, comparison and editing controls built around iteration.
Evaluation, Feedback and Review Screens
Rating, correction, flagging and annotation flows that turn user feedback into data your team can act on.
Usage, Billing and Admin Controls
Credits, token and seat meters, model selection, permissions, audit logs and spend limits for teams and enterprises.
Features/Why Choose Us
- Agents that show their plan
Gartner warns over 40% of agentic AI projects may be cancelled by end 2027; we design clear scope, visible steps and approvals so projects earn lasting trust.
- Provenance in every answer
Sources, retrieval context and confidence cues appear beside the output, with an easy path to flag a wrong answer.
- Automated decisions made contestable
Where an AI outcome affects a person, we design explanation and human-review routes aligned with GDPR Article 22 and EU AI Act transparency rules from August 2026.
- Cost control as interface
Per-run estimates, budgets, caching cues and model-choice controls make spend visible before it becomes a surprise.

Frequently Asked Questions
What do your AI app development services include?
User research, interaction design for AI behavior, clickable prototypes, visual design, a design system with AI components, front-end development with your engineers or ours, accessibility checks, analytics and post-launch optimization for web and mobile AI products.
Do you build the models or only the interface?
We focus on product design and front-end development. We work with your ML team or API providers on the model side and shape the interface around what the system can reliably do.
Can you redesign our existing AI app or chatbot?
Yes. We review conversation logs, feedback and analytics to find where users give up or distrust the output, then redesign those flows while keeping your models and backend in place.
How much does AI app development cost?
It depends on the platforms, number of user roles and AI features, whether a design system is needed and whether we build the front end. After a short discovery call we scope a fixed price for a defined release or a monthly retainer for continuing work.
How do you design safe and controllable AI agents?
Each agent gets a stated scope, shows its plan before acting, asks for approval on consequential steps, logs what it did and offers undo. These patterns help teams avoid the unclear interfaces behind many stalled agent projects.
How do you handle AI disclosure, privacy and explanation rules?
We design disclosure labels for the EU AI Act transparency rules from August 2026, and explanation and human-review paths where GDPR Article 22 may apply. We document the decisions, while your legal team confirms what applies to you.
How do you keep AI usage costs under control?
The interface shows estimated cost before expensive runs, offers budgets and limits for teams, suggests lighter model options for simple tasks and reuses earlier results where it can.
Who owns the designs, the system and the code?
You do, from the first week. Figma files, tokens, documentation and any code we write live in your own accounts and the contract assigns the intellectual property to you.
