Episode: Seeing The Future from AI Companions to Personal Software
Date: November 5, 2025
Host: Andreessen Horowitz (a16z)
Guest: Eugenia Kuyda (Founder of Replika, Wabi)

Overview

This episode explores the future of personal software in the AI era, focusing on how current AI interfaces are just the beginning. The conversation centers on breaking free from the limitations of chatbots-as-apps, the rise of mass-created and deeply-personalized software, and what it means for technology, creativity, and consumer behavior as nearly anyone gains the ability to build “mini-apps.” The discussion features Eugenia Kuyda—known for launching Replika and now Wabi—who shares her perspective on how software is moving toward hyper-personalization, ephemeral utility, and new forms of collaboration and creation.

Key Discussion Points and Insights

1. The Limitations of Current AI Interfaces

• The "Microsoft DOS" Era of AI

  • Current chatbot interfaces are compared to the early days of computing—functional, but limiting in potential use cases.
  • Despite advances in model capabilities, most users stick to classic, simple interactions like search or writing help ([02:30]).
  • “We got obsessed with this metaphor that the current chatbots are really the Microsoft DOS era for AI interfaces, and that there will be some sort of a Windows macOS moment.” —Eugenia Kuyda ([03:32])

• Interface, Not Intelligence, Is Holding Us Back

  • The bottleneck is not AI’s intelligence as much as the interfaces that surface its capabilities ([02:30], [03:32]).
  • The need for richer, more visual, and simpler tools for users to uncover the full potential of AI.

2. The Rise of Personal, Ephemeral, and Mass-Created Software

• Mini-Apps for Everyone

  • Shift from apps built solely by professional developers to a world where anyone can remix, share, and personalize software ([04:22], [05:57]).
  • Use cases: ultra-niche motivational apps, custom bedtime games for children, personalized trackers ([05:57]).

• Personalization at the Core

  • Mini-apps anchored to individual needs, context, and dynamic tweaking—"operating system built on you" ([04:22], [06:45]).
  • Ephemeral use: Apps are as disposable (or remixable) as a meme or TikTok—perfect for fleeting needs ([07:29]).

• Community and Social Graphs for Apps

  • Coming features include in-app social graphs: see who’s downloading, remixing, and tweaking mini-apps ([09:45]).
  • App creators and users interact like in content platforms, shifting app discovery and improvement into a social/communal space.

3. From “Vibe Coding” to “Vibe Designing”

• No-Code, No-Tech Jargon

  • Wabi’s philosophy: remove all technical barriers—no code, API keys, or integrations jargon ([11:53]).
  • “Vibe coding” and even more so “vibe designing”—the act of building by intuition, taste, and creative intent, not by script ([13:00]).

• Platform Benefits

  • Inspiration from Canva’s ease-of-use and Shopify’s platform approach—users build within guided, intuitive frameworks ([15:40], [17:04]).

4. Creators, Community, and Monetization

• Creators as Forces for App Innovation

  • Forecast of professional and niche creators emerging in the mini-apps space, mirroring YouTube’s evolution for video ([29:39]).
  • Example: Fitness influencers could share their protocols as mini-apps rather than PDF guides or courses ([27:40]).

• New Styles, New Communities

  • Style and perspective will matter. Users may prefer apps created by certain designers or thinkers for their look, feel, and approach ([30:35]).

• Feedback, Remix, and Collaborative Creation

  • Real-time feedback and requests for tweaks, remixing, and collaborative adjustment is built in ([09:45], [21:12]).

5. The Evolution (and Lessons) of AI Companions

• Reflections from Replika’s Early Days

  • Early belief in meaningful AI conversation as a core human benefit ([01:31], [33:22]).
  • Surprised by the reality even after deeply believing (“It just still felt like complete magic" [33:22]).

• Pioneering Language Models and OpenAI Collaboration

  • First-mover advantage, scrappiness, and unique struggles.
  • Fine-tuned early OpenAI models before they were mainstream; lessons on risk-taking and capital requirements ([33:22], [37:15], [41:10]).
  • “Sometimes you need to sort of go big or go home. Not having the balls to do that, especially in this current environment, I think you can suffer the consequences.” —Eugenia Kuyda ([41:10])

6. The Psychosocial Shift: From Apps as Tools to Apps as Content

• Apps as Content and Community Starters

  • Transitioning mindset: software is not just a tool, but a shareable, creative expression ([27:40], [29:34]).
  • The arrival of subcultures, “weird apps,” and micro-communities—returning to the unpredictable, wild-west energy of the early web ([32:16]).

• Prompt Sharing & AI Discovery as a Mass Market Behavior

  • Millions already trade prompts for creativity or utility, but methods are awkward (copying/pasting text, comments on TikTok) ([22:22], [23:24]).
  • Mini-apps designed to streamline discovery, use, and remix of AI functionality ([25:26]).

• “The world has 1% of the software that it needs.”

  • A vision of 100x growth in new, meaningful, hyper-tailored applications over the next five years ([27:24]).

7. Hardware and Interfaces of the Future

• Skepticism of “Voice-Only” AI Devices

  • Overhyped “voice-first” narrative: voice is useful but not sufficient as the primary interface ([00:00], [45:53]).
  • “I think there's a huge mind trap among builders ... they somehow think that voice is the main interface … it's completely wrong. I love screens.” —Eugenia Kuyda ([45:53])

• AI-First Operating Systems

  • Envisioning new hardware that centers AI, runs models locally, and allows on-the-fly creation and deep personalization ([47:30]).
  • “AI is just an app on your phone. It should not be that way.” ([00:00], [49:07])

8. Predicting Consumer Behavior

• Empathy Drives Intuitive Design
  • Eugenia attributes her insights to journalism roots, curiosity, and empathy—seeing unmet needs among ordinary users ([43:14]).
  • Importance of observing people’s struggles with current interfaces (e.g., her mom’s difficulty copying prompts) ([43:14]).

Memorable Quotes

• On AI's Interface Problem:
  "When people look at a command line or a chatbot, they really just see search, writing tool ... that’s the affordance of a command line. We need something more interactive, visual, simple for everyone." — Eugenia Kuyda ([02:30])

• On Personal Software:
  “Think of it as an operating system built on the platform of you and not on some random fixed context.” — Eugenia Kuyda ([04:22])

• On Personalized Mini-Apps:
  “People are building very particular things to fit their needs ... I built a game for my daughter with Princess Elsa and Jasmine in minutes, which would have taken forever to find, if it existed at all.” — Eugenia Kuyda ([05:57])

• On Democratizing Software Creation:
  "All of the software that we consume is downstream of the preferences of [20 million] developers. If more people could make software, they would." — Anish ([10:53])

• On Community and Social Creation:
  “It’s not just about building apps for yourself. It’s about discovering, tweaking, and sharing—with friends, family, or anyone.” — Eugenia Kuyda ([09:45])

• On Hardware of the Future:
  “There's a huge mind trap ... that voice is the main interface ... I love screens. There’s no way with voice to solve for discovery, for productivity." — Eugenia Kuyda ([45:53])
