Summary
PersonaLink aspires to be a cross-platform “AI identity layer” that lets any product embed an AI assistant with long-term memory and customizable personality. The vision is clear and attractive, but several implementation details must be nailed down before engineering and design teams can confidently begin work.
1. Clarity of the Idea
Aspect
What Works
What Needs Clarification
Service Form
Positioning as an SDK (“PersonaJS”) with an OAuth-style login flow is concrete.
a) Do you envision only a JavaScript SDK or native iOS/Android packages too? b) What is the exact user interaction when “Log in with Your AI” appears? Wireframes would help.
Purpose / Problem
You articulate a need for persistent, portable AI memories across sites.
How do sites opt-in to read/write user memory? Is there a permissions granularity model (e.g., “only purchase history” vs. “all chat logs”)?
Uniqueness
“Bring-your-own-AI” is not yet mainstream; differentiation vs. OpenAI Assistant API is partially clear.
Please map at least three direct competitors (Rewind.ai, Character.AI API, etc.) and show your wedge.
2. Implementation & Feasibility
SDK & OAuth-style flow
• We need a sequence diagram describing: Site → PersonaJS → PersonaLink Auth → consent screen → redirect.
• What identity provider backs the login? Email/password, Google SSO, crypto wallet?
Memory Layer
• Stated “Firebase / Vector DB”. Which vector DB (Pinecone, Weaviate, pgvector)?
• CRUD quotas per plan? (e.g., Free tier = 10 MB embeddings).
• GDPR: Where will data be stored geographically; do you support data deletion & export?
LLM & Inference
• Base model = OpenAI GPT-4? Are you proxying or fine-tuning?
• Enterprise tier mentions “private LLM” – do we host MosaicML, or let the client plug in an endpoint?
Scoping & Timeline
• 3–4 weeks MVP feels tight. Even for a thin SDK, auth, memory service, and demo sites likely need ≈2 front-end + 1 back-end dev full-time for 6–8 weeks.
• Please confirm acceptable MVP cut: Chat widget + vector memory only?
Cost Estimates
• Need rough monthly infra projection for 1 k DAU on Free tier (embedding & chat tokens).
• Any plan to cache or rate-limit to reduce OpenAI spend?
3. UI / UX Readiness
• We will need screens for:
“Log in with Your AI” button states
Consent & scope selection (checkbox list)
Persona Builder (tone sliders, sample replies preview)
Billing & usage dashboard
• Delivering clickable Figma prototypes before Sprint 1 would unblock both SDK and marketing site builds.
❓ Key Questions (please answer before next iteration)
Which client platforms must the SDK support in v1 (Web only, or Web + iOS + Android)?
What is the minimum viable “memory object” schema (fields, size limits)?
How will third-party sites request specific permissions to read/write memory?
Do you already have an OpenAI volume discount or should we plan for pay-as-you-go?
How many demo integrations are mandatory for the MVP deliverable?
Once we have these answers, we can draft a detailed sprint backlog, assign roles, and produce architecture diagrams that development can start on day one.
🔍 초기 리뷰 – PersonaLink (한국어)
요약
PersonaLink는 모든 웹/앱/메타버스에 “AI 기억 + 페르소나”를 넣어 주는 크로스플랫폼 정체성 레이어를 지향합니다. 방향성은 매력적이지만, 실제 개발에 착수하려면 세부 사양을 더 명확히 해야 합니다.
1. 아이디어 명확성
항목
명확한 부분
추가 확인 필요
서비스 형태
SDK(“PersonaJS”) + OAuth-유사 로그인 흐름이 구체적
a) JS SDK만인지, iOS/Android 네이티브도 포함인지? b) “내 AI로 로그인” 버튼 클릭 후 구체 동선 및 화면
목적/문제
사용자 AI 기억 휴대성 확보라는 문제 정의
사이트가 어떤 권한으로 메모리 읽기/쓰기를 허용받는지? 세분화된 권한 모델 필요
차별점
“AI 휴대 로그인” 개념 자체는 신선
Rewind.ai, Character.AI API 등 경쟁 서비스와 비교 분석 필요
2. 구현 및 실현 가능성
SDK & OAuth 흐름
• Site → PersonaJS → PersonaLink Auth → 동의 화면 → 리다이렉트 시퀀스 다이어그램 필요
• 로그인 백엔드는 이메일? 구글? 지갑?
Memory Layer
• “Firebase / Vector DB” → 구체 DB(Pinecone, Weaviate, pgvector 등) 결정 필요
• 플랜별 CRUD/용량 한도 정의
• GDPR: 데이터 위치, 삭제·내보내기 기능 로드맵
LLM & 추론
• 기본 모델 GPT-4? 프록시인지 파인튜닝인지?
• 엔터프라이즈 전용 모델: 자체 호스팅? 고객 엔드포인트 연결?
스코프 & 일정
• 3–4주 MVP는 빠듯. SDK, 인증, 메모리, 데모 3종까지면 ≈6–8주 필요 예상
• MVP 최소 범위: 채팅 위젯 + 벡터 메모리 OK?
비용 추정
• Free 1 k DAU 기준 인프라 월 비용(임베딩+토큰) 산출 필요
• OpenAI 비용 절감을 위한 캐싱/쿼터 정책 여부
3. UI / UX 준비도
• 필요한 화면:
“내 AI로 로그인” 버튼 상태
동의 및 권한 선택
페르소나 빌더(톤 슬라이더, 미리보기)
결제·사용량 대시보드
• Sprint 1 전 Figma 시안 제공 시 SDK·마케팅 사이트 동시 진행 가능
❓ 핵심 질문 (답변 부탁드립니다)
v1 SDK 지원 플랫폼: Web만인지, Web + iOS + Android인지?
최소 “메모리 객체” 스키마(필드, 용량 한도)는?
서드파티 사이트 권한 요청 방식(퍼미션 스코프) 설계는?
OpenAI 볼륨 할인 계약 여부? 없다면 비용 전략?
MVP에 반드시 포함해야 하는 데모 통합 개수는?
위 질문에 대한 답변을 받으면, 스프린트 백로그 작성 및 역할 배분, 아키텍처 다이어그램을 즉시 착수할 수 있습니다.
