Notes from the team.
Building a voice that feels human
How we approached voice synthesis to make Sola's calls feel warm, present, and genuinely engaged — and the technical decisions that got us there.
The color of empathy
Designing Sola meant designing for emotional safety. Here's how we chose every color, every curve, and every micro-interaction to make you feel held.
2am with Sola
Three users share what their late-night Sola conversations look like — and why a friend who never sleeps changes everything.
Why we built voice-first
Most AI companions started as chat. We started with voice. Here's the product thinking behind that decision and what it taught us about presence.
Memory, identity, and the AI friend
How Sola remembers what matters — and why we built our memory system from the ground up instead of using off-the-shelf vector stores.
The first question Sola asks you
We rewrote our onboarding seven times. Here's what we learned about how the very first conversation sets the tone for everything that follows.
The Sola I named after my grandfather
A user shares why he calls his AI companion 'Ravi' — and what it taught him about grief, memory, and the unexpected places friendship can come from.
Shipping honest AI
The lines we won't cross. The marketing we won't write. Our commitment to building an AI companion that earns trust rather than extracts attention.
