Compare Fostera and Gemini side by side — memory of past chats, Keep Activity and training, export and import, age rules, usage limits, and free access.
| Feature | Fostera | Gemini |
|---|---|---|
| Primary purpose | AI companion with persistent Soul identity and project context | General-purpose assistant spanning Google's surfaces |
| Memory depth | Selective Soul and project memory that users can inspect, edit, and delete; relevance-based retrieval can miss details | Memory of past chats for eligible users; Google says it is not available in Gems and may not always be correct |
| Memory controls | Inspect, edit, and delete selected memories; cleanup can take up to 30 days | Turn Memory off, or delete the source chats in Gemini Apps Activity; Instructions for Gemini are separately editable |
| Project boundaries | Separate Souls and projects with their own context | Gems take their own instructions and files, but memory of past chats does not apply inside them |
| Data export and import | Gemini import: beta. Use Google Takeout for My Activity → Gemini Apps and select MyActivity.json, or export a prompt from Google AI Studio as JSON. | Gemini Apps Activity downloads through Google Takeout, which frequently omits response text |
| Training and data use | Connected provider terms vary; memory deletion cleanup may take up to 30 days | Activity can be used to improve Google's services, including training generative models, while Keep Activity is on; it is on by default for adults |
| Age and eligibility | SFW, ages 13+; confirmed guardian consent is required for ages 13–17 | Memory and Personal Intelligence need an adult personal Google Account; connected apps are unavailable in the EEA, UK, Switzerland, and Nigeria |
| Usage limits | Flexible monthly capacity on Free; Core and Premium add capacity | Limits refresh every five hours up to a weekly limit and may change without notice |
| Free tier | 3 Souls with flexible monthly capacity for conversations, media, creations, analysis, voice, and automation | Free with a Google Account, including image generation, Deep Research, Gemini Live, Canvas, and Gems; limits can change |
Gemini documents memory of past chats, Instructions, Gems, and Connected Apps as separate settings, each with its own eligibility, and memory does not apply inside Gems. Fostera centers continuity on one Soul or project with editable memory, visible progression, and Premium manual selection among eligible engines.
