AI models are racing ahead on powerful servers, but the browser is quietly catching up. In this talk, Phil Nash, Developer Advocate at DataStax, shows how the web platform is becoming a powerful space for AI experimentation—no GPUs required. You'll learn how to build a browser-based, offline-capable speech-to-speech translator (yes, a babelfish!) using only web technologies. Phil breaks down how AI models can now run right inside the browser and what the future holds as these capabilities become even more native to the web. #AIInTheBrowser #Babelfish #WebAI #OfflineApps #SpeechToSpeech #PhilNash #FrontendNation #FEN2025 Web browsers are no longer just a UI layer. This session shows how they're evolving into AI-powered platforms; right in your hands. 💻 Read our blog: https://frontendnation.com/blog 🎟️ Sign up for Frontend Nation 2026 to stay updated: https://frontendnation.com/ 💜 Special thanks to all our event sponsors for 2025: Diamond Sponsors AG Grid: https://www.ag-grid.com/charts/?utm_source=frontend-nation&utm_medium=logo&utm_campaign=frontend-nation-sponsorship-2025 BitterBrains: https://bitterbrains.com/ Vue School: https://vueschool.io/ Certificates.dev: https://certificates.dev/ InstantDev: https://instantdev.io/ Platinum Sponsors Cypress: https://www.cypress.io/ Sentry: https://sentry.io/signup/?utm_source=event&utm_medium=sponsored-event&utm_campaign=general-fy26q2-evergreen&utm_content=signup-frontendnation2025-signup JavaScript Cert: https://certificates.dev/javascript Vue.js Cert: https://certificates.dev/vuejs/ Angular Cert: https://certificates.dev/angular React Cert: https://certificates.dev/react Nuxt Cert: https://certificates.dev/nuxt TypeScript Cert: https://certificates.dev/typescript Agorify: https://agorify.com/ Gold Sponsors Mastering Nuxt: https://masteringnuxt.com/ Mastering Pinia: https://masteringpinia.com/ LevelUp DX: https://levelupdx.com/
