TL;DR
- Ground fintech answers in approved internal content with RAG instead of model memory.
- Keep customer or transaction content inside VPC, on-prem or air-gapped deployments where policy requires it.
- Scope retrieval per team, client or site so permissions and confidentiality hold at query time.
- Keep a named human owner for every customer or regulatory decision.
- Keep sandbox and production indexes separate.
How it works, step by step
- Inventory the content to make searchable: KYC procedures, risk policies, API documentation and partner onboarding material.
- Define a data boundary for the pilot that excludes restricted material until controls are proven.
- Choose a deployment target: cloud for public content, VPC, on-prem or air-gapped for restricted data.
- Build an evaluation set with compliance and support leads so answer quality is judged by domain experts.
- Ingest, chunk and embed approved documents, and require citations on every answer.
- Add refusal behavior for questions outside the indexed, approved content.
- Review logged interactions on a schedule and expand only after accuracy and access checks pass.

Where fintech teams start
Start with internal questions that already have a written answer. High-value first workloads include:
- KYC and onboarding procedures: answer analyst questions from current procedures.
- Risk and compliance policy: retrieve policy text and exception handling with citations.
- API and integration docs: support engineers with sourced answers from internal documentation.
- Partner support: answer from partner agreements, service levels and onboarding guides.
Each use case augments staff with cited answers; none replaces compliance owner judgment.
A private RAG architecture for fintech knowledge
The stack is consistent across industries: ingest approved KYC procedures, risk policies, API documentation and partner onboarding material, chunk and embed with a multilingual embedding model, store vectors inside your environment, and call chat completions that answer only from retrieved context. Plugsky embeddings and chat completions are OpenAI-compatible, so teams already using OpenAI SDKs change the base URL and keep their code.
Separate sandbox and production corpora, tag chunks with environment and product line, and re-embed when procedures change. Use JSON mode when answers feed onboarding or case tools, and log every retrieval for review.
Access control, confidentiality and audit
Customer data, transaction-adjacent records and partner agreements need separation by environment and client. Apply the same access rules you use for production data, keep sandbox and production corpora apart, and log every query for compliance review.
The technical controls are consistent: enforce permission-aware retrieval in your own service layer, scope API keys per application, team or tenant, rotate keys, and retain request and response logs on a defined schedule. Regulatory obligations vary by jurisdiction and sector, so map them with counsel rather than assuming one framework covers every deployment; Plugsky supplies the deployment and logging primitives you document.
See DPAs for AI APIs for related deployment and control detail.
Rollout and human oversight
Pilot on published product and process docs before touching customer or transaction content. Build a labelled question set with compliance and support leads, then measure retrieval hit rate, citation correctness and answer accuracy before and after every index or model change. Require citations on every answer, refuse out-of-scope questions, and name a human owner for every customer or regulatory decision.
Review logged interactions weekly at first, correct the index rather than the prompt when retrieval misses, and expand the corpus only when accuracy and access checks pass.

Frequently asked questions
Can fintech teams keep data private with Plugsky?
Yes. Choose the deployment boundary that matches the data: Plugsky cloud for public content, or your VPC, on-prem and air-gapped options for restricted material. Access is controlled with scoped API keys and usage analytics.
Do we need to fine-tune on our internal documents?
Not for a first release. Fine-tuning is coming soon and is better for style than facts. RAG keeps answers current, permission-aware and traceable to a source, which matters more for internal knowledge.
Which model should we use?
Start free with plugsky-micro and plugsky-lite to validate retrieval, then evaluate mid-tier and frontier models from the 30+ model catalogue on your own question set.
How do we stop wrong or unsupported answers?
Restrict the assistant to approved indexed content, require citations, refuse out-of-scope questions and keep a human decision-maker for every regulated or client-facing outcome.
How is pricing structured?
Self-serve plans are flat monthly with unlimited fair-use usage, and there are no per-token charges on self-serve plans. See the live pricing page for current plans and the free tier.
Can we use it in a regulated environment?
Plugsky provides deployment, access and logging controls you can document in your compliance program. Confirm specific obligations with your regulator-facing team and counsel.
How do we keep sandbox and production data apart?
Use separate API keys, separate indexes and environment tags; never index production data into a sandbox workspace.
