Compare Fostera and Microsoft Copilot, the consumer app at copilot.microsoft.com — memory controls, training, export, age rules, and plans.
| Feature | Fostera | Microsoft Copilot |
|---|---|---|
| Primary purpose | AI companion with persistent Soul identity and project context | Microsoft's consumer assistant at copilot.microsoft.com — not the GitHub Copilot coding product |
| Memory depth | Selective Soul and project memory that users can inspect, edit, and delete; relevance-based retrieval can miss details | Microsoft says Copilot remembers key details and preferences such as communication style, favorite topics, goals, and recurring tasks |
| Memory controls | Inspect, edit, and delete selected memories; cleanup can take up to 30 days | Microsoft says you can view, edit, and delete what Copilot remembers under Personalization and memory; chat history stays |
| Project boundaries | Separate Souls and projects with their own context | One assistant with saved memories; Microsoft says a Microsoft account is required to use Copilot |
| Data export and import | No structured Microsoft Copilot import is available. Start fresh or paste selected conversation text at /switch and review the extracted context. | Microsoft's privacy dashboard exports all Copilot app activity history as a CSV file |
| Training and data use | Connected provider terms vary; memory deletion cleanup may take up to 30 days | Microsoft says app prompts, responses, and files aren't used to train foundation models; a Privacy setting opts conversation activity out |
| Age and eligibility | SFW, ages 13+; confirmed guardian consent is required for ages 13–17 | Microsoft says you must be at least 13, higher in some countries, and that Copilot isn't available everywhere |
| Usage limits | Flexible monthly capacity on Free; Core and Premium add capacity | Microsoft says its paid Microsoft 365 plans add Copilot chat with higher usage than free |
| Free tier | 3 Souls with flexible monthly capacity for conversations, media, creations, analysis, voice, and automation | Microsoft's plan page lists paid Microsoft 365 tiers with trial offers; Microsoft says some advanced features may be available only to users with eligible subscriptions |
Microsoft says Copilot app prompts, responses, and files aren't used to train foundation models, a strong default. Copilot is still an assistant tied to a Microsoft account, and its August 2026 update retired Group Chat, Podcasts, and Deep Research. Fostera keeps a Soul above the engine.
