Fraiend: AI Chat & Companion

Your AI that remembers you.

Fraiend is not a chatbot — it's Agentic Chat is a full agentic Swiss Army knife in your pocket. Switching to companion mode, it is your a long-term companion with persistent memory, real emotional awareness, and message chat with you like real person. Two apps, one install.

Agents are distilled from iconic thinkers and backed by curated knowledge bases, with graph-based KB retrieval and active web search.

Also, an special agent DSE-Eng-P2 is provided. I promise it will be the best AI marker for dse-eng-p2.

Agent Mode Multi-session AI with tools
━━━━━━━━━━━━━━━━━━━━━━━━━━

Switch to agent mode and you get a full workbench: per-agent conversations, native function calling, and an autonomous tool loop that can search the web, scan your knowledge base, and chain tools before answering. The agent handles context windows automatically — old messages are archived and summarised so you never run out of space.

- Very proactive web searching that you can choose to enable or not
- Knowledge base via vector search (ChromaDB) or file-based KB
- Session archiving + semantic search (find anything you said)
- Expandable thinking content for reasoning-heavy models
- Title auto-generation, rolling summaries, attachment OCR/ASR, image understanding.

━━━━━━━━━━━━━━━━━━━━━━━━━━
Companion Mode Human-like interaction
━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Each companion has its own personality and emotional state (8 dimensions that rise and fall based on your conversations). They don't just reply — they remember facts about you, track your shared history, and write private files called USER.md and RELATIONSHIP.md that evolve as you talk. You can chat, voice-call, or video-call — the companion adapts its style to the mode. Just like texting a real person.

- Persistent identity files auto-maintained by the AI
- Memory fragments with keyword + vector + entity fusion search
- Multi-bubble splitting
- Profile pictures, contact list

Pre-built Agent Catalog
━━━━━━━━━━━━━━━━━━━━━━━━━━

The app ships with concept-level companions and agents that have real thinking frameworks — not simple character prompts. Agents for Mao Zedong's strategic thinking, classic Tianya forum wisdom, and distilled personas built from public-domain writings. Every agent can search the web and query its own knowledge graph before answering.

━━━━━━━━━━━━━━━━━━━━━━━━━━
Privacy & Syncing
━━━━━━━━━━━━━━━━━━━━━━━━━━

Google Sign-In only — no passwords. Both companion and agent conversations are stored server-side, so you never lose a message when switching devices. Companion mode keeps a local SQLite cache for instant offline access; agent mode uses the server as the primary store. All data is per-user isolated and encrypted — no one else can access your chats, identity files, or memories. Even the developer have NO way to see your data. One-tap server backup and restore makes moving to a new phone painless.

━━━━━━━━━━━━━━━━━━━━━━━━━━
Pricing GENEROUS free credit
━━━━━━━━━━━━━━━━━━━━━━━━━━

Every user gets $0.5 free credits that refresh twice a day, completely enough unless you use pro models. When you need more power, purchase one-time credit packs or subscribe monthly ($1.99/month) to triple your free-credit refill and slash Pro-Slow from 12× to 5×.
