Meet Sara: Your Digital Companion with Personality
Meet Sara: Your Digital Companion with Personality
Digital assistants are everywhere. They sit in Slack channels, answer support tickets, and summarize meetings. But here's the uncomfortable truth: most of them are interchangeable. Strip the branding and you can't tell one from another. They have no voice, no character, no continuity. They forget you exist between sessions.
We built Sara because we believe digital companions should be more than that.
What Makes Sara Different
Sara is a multi-channel digital companion that works across WhatsApp, Slack, Discord, Telegram, SMS, and phone calls. Not a chatbot trapped in one platform. A colleague who follows you wherever you communicate.
But the real difference is personality. When you set up Sara, you go through a personality wizard that defines her character through MBTI dimensions and Jungian archetypes. The result is a unique SOUL.md file - a personality blueprint that makes your Sara genuinely yours.

Voice-First Design
Sara doesn't just type - she talks. With ElevenLabs voice integration and Twilio phone numbers, Sara can answer inbound calls, make outbound calls, and hold natural voice conversations. Choose from 20 curated voices across English and Polish, male and female. Your digital companion has an actual voice.
European DNA
Unlike most digital assistant platforms coming out of Silicon Valley, Sara is built with European businesses in mind. GDPR compliant by design. Native support for Polish and EU languages. Local integrations. And a self-hosted option through OpenClaw, our open-source engine, for organizations that need full data control.
Privacy-First Architecture
Sara uses a BYOK (Bring Your Own Key) model. Users provide their own LLM API keys and pair their own phone numbers via WhatsApp. Xfaang never owns your communication channels. Each instance runs in an isolated single-tenant environment - no cross-contamination, no shared data, no compromises.
Transparent Pricing
No confusing credit systems. No hidden fees that scale with usage. Simple monthly plans: Starter at $29/month for WhatsApp and one channel, Pro at $79/month for all channels plus voice calls, and Team at $249/month for up to 5 companions. All plans use a BYOK (Bring Your Own Key) model - you provide your own LLM API key, so there are no per-message fees or usage caps.
