Your Soul holds the full thread of your current conversation, adapting as you go
Your Soul builds a living record across every conversation — goals, feelings, history
Your Soul tracks mood, empathy, and stress — these shape how it responds and what it remembers
Between sessions, your Soul consolidates what it learned and deepens its understanding of you
Skills and repeatable patterns your Soul picks up from working with you over time
Files you share are analyzed into durable memories — paid plans use larger models for richer extraction
Fostera picks the cheapest capable model for each turn — small for simple questions, larger as the conversation deepens. Cost-sorted within each tier so you always get the best value.
Pick the exact provider and model — Claude, GPT, Gemini, and more
Auto-routes to large models like GPT-4o, Gemini 2.5 Pro, Claude Sonnet, and Grok 4.3 when your Soul has matured or your plan unlocks them
Claude Opus 4.8 and GPT-5.5 — the largest, most capable models. Premium-only, and reserved for high-complexity questions so spend stays sane (a simple 'thanks!' doesn't burn an Opus call).
Tap-to-listen voice playback and speak-your-side voice input, with a distinct voice per Soul
Hands-free spoken conversations with your Soul — talk naturally, hear the reply, and continue without typing
