Interactive Rive animation for real products.
App mascots, AI companions and UI motion for apps, SaaS and websites—with purposeful state machines and developer-ready handoff.

I’m a freelance Rive animator and interactive motion designer specializing in app mascots, AI assistants, animated user interfaces and expressive robot faces.
A great animation should respond naturally to what your users and your application are doing. I help developers and product teams create interactive Rive animations—from a mascot that reacts to progress to an AI assistant that listens, thinks and speaks.
Each project can include organized timelines, reusable rigs, state machines, documented inputs and integration guidance tailored to your product.
Designed for motion.
Structured for development.
The final asset formats, controls and integration support are agreed in the project scope. Runtime support determines the available features.
Whether you’re launching a mobile app, building a SaaS dashboard or creating a conversational AI experience, I can help you build motion that feels native to your product.
Give your mobile app a character that reacts to real user actions. Idle animations, greetings, celebrations, progress reactions, achievements and emotions, connected through custom state controls.
Explore app mascot animationCreate an expressive AI character with listening, thinking, speaking and emotional states, plus eye movement and configurable facial expressions.
Explore AI companion animationBring personality to robot displays with animated eyes, blinks, emotions and mouth shapes. The animation architecture is planned for the device’s supported display and runtime.
Explore AI robot face animationCustom character animation, animated interfaces, onboarding interactions and product feedback—built as reusable assets for real integration.
Explore Rive animation servicesAnimated buttons, loading indicators, success states, navigation, progress and interface transitions that make product interactions easier to understand.
Explore UI animationGive conversational AI a visual presence with listening, processing, speaking, audio-reactive motion and configurable facial controls.
Explore voice assistant animationI build interactive animation assets that developers can connect to application events, user input and changing product states.
Reusable rigs, documented controls and clear handoff give your team a practical route from animation concept to product integration.
Explore developer resourcesIdle, Listening, Thinking, Speaking, Success, Error and Celebration, with transitions designed around your product’s interaction requirements.
Documented inputs, properties and triggers let developers control expressions, gestures and reactions through a clear animation contract.
Organized Rive assets and scoped guidance for supported JavaScript, React, Flutter and React Native workflows. Feature support is checked against the target runtime.
Layouts prepared for different display sizes, with performance constraints and reduced-motion alternatives considered during the project.
Case studies will show the animation concept, interaction behavior, technical controls and implementation approach. Client projects are awaiting supplied source material and publication permission; the examples below are original browser-based concept studies.
Switch between idle, happy, listening, thinking and speaking poses. An illustrative CSS prototype, with no Rive asset or hardware connection.
Explore the interactionAdjust a cubic-bezier curve, preview a transition and copy the CSS for your own interface.
Try the easing toolInteractive mascots can serve as guides, companions, coaches, reward characters or animated assistants inside a product. Their behavior follows what is happening in your application.
I design these responses using reusable character animation and Rive state machines, giving developers a practical way to connect motion to product logic.
Explore interactive mascotsAn app mascot acknowledges confirmed progress when a user completes a task.
An AI companion switches between listening, thinking and speaking as the conversation changes.
A virtual pet changes its expression as the application updates its activity or energy.

The product’s behavior guides the animation from the first discussion to the final export.
Explore the full processDefine where the animation appears, how users interact with it and which behaviors your application needs to control.
Create or prepare the illustration, organize movable parts and build a reusable character rig.
Develop animation states, transitions, state-machine logic and expression controls.
Review the animation behavior and refine it around your intended interactions and agreed target runtime.
Deliver the agreed animation files, control details and integration guidance. Production application code is included only when explicitly scoped.

Discuss your projectA Rive animator creates interactive animations using Rive. Animation can respond to application states, triggers and user interactions through features such as state machines.
Rive provides runtimes for supported web and mobile platforms. Implementation depends on the runtime version, required features and integration architecture. Assets and controls are prepared with the target platform in mind.
Yes. I create animated mascots with character rigs, expressions, idle loops, progress reactions, celebrations and other behaviors controlled through Rive state machines.
Yes. I create interactive animation systems for AI assistants and chatbot characters, including listening, thinking, speaking and emotional states. Additional facial and mouth controls can be scoped around your product requirements.
Yes. I design digital faces with eye movements, blinking, emotions and configurable mouth shapes. Runtime and hardware compatibility must be evaluated for the target device.
Deliverables depend on the agreed scope and may include .riv files, organized animation controls, input mappings, interaction specifications and integration examples for the supported target runtime.
Yes. I can evaluate existing vector or layered artwork, identify missing parts needed for movement and prepare it for rigging and animation.
Pricing depends on character complexity, illustration requirements, animation states, interactive controls, platform constraints and testing needs. Share your project details for a tailored estimate.
I’m Praneeth Kawya Thathsara, a freelance interactive motion designer specializing in Rive.
My work combines character animation, Rive state machines, reusable rigs and developer-oriented handoff to help teams integrate interactive motion into websites, mobile apps, AI interfaces and companion experiences.
I collaborate with founders, designers and development teams to turn static product ideas into interactive visual experiences. My wider product design practice runs through Kanthaka Labs.
