How can consulting firms use RAG for internal knowledge?

Key facts

API surface	OpenAI-compatible /v1/chat/completions; keep your existing SDK
Grounding	Embeddings and RAG are live for engagement, methodology and proposal search
Models	30+ models behind one API, from free tiers to frontier
Deployment	Plugsky cloud, your VPC, on-prem or air-gapped
Access control	Scoped API keys, rotation and usage analytics; enterprise SSO and RBAC options
Auditability	Request and response logging with usage analytics
Pricing model	Flat monthly self-serve plans; no per-token billing on self-serve
Free tier	Free plan with plugsky-micro and plugsky-lite; 14-day full-access trial

TL;DR

• Ground consulting answers in approved internal content with RAG instead of model memory.
• Keep client-confidential 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 client-facing decision.
• Keep per-client workspaces where confidentiality demands it.

How it works, step by step

1. Inventory the content to make searchable: engagement deliverables, methodologies, proposals and industry research.
2. Define a data boundary for the pilot that excludes restricted material until controls are proven.
3. Choose a deployment target: cloud for public content, VPC, on-prem or air-gapped for restricted data.
4. Build an evaluation set with engagement managers and subject specialists so answer quality is judged by domain experts.
5. Ingest, chunk and embed approved documents, and require citations on every answer.
6. Add refusal behavior for questions outside the indexed, approved content.
7. Review logged interactions on a schedule and expand only after accuracy and access checks pass.

Where consulting teams start

Start with internal questions that already have a written answer. High-value first workloads include:

• Methodology and asset search: retrieve frameworks, templates and accelerators with citations.
• Proposal and bid support: answer from past proposals, delivery models and case studies.
• Engagement knowledge: surface deliverables, interviews and research within the engagement boundary.
• Industry research: pull cited findings from market studies and analyst notes.

Each use case augments staff with cited answers; none replaces engagement lead judgment.

A private RAG architecture for consulting knowledge

The stack is consistent across industries: ingest approved engagement deliverables, methodologies, proposals and industry research, 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.

Engagement metadata is the backbone: every chunk carries client, engagement and permission tags. Use a reranker to improve precision on long research documents, and keep a per-client workspace where confidentiality demands it.

Access control, confidentiality and audit

Confidentiality is per engagement, and client names themselves can be sensitive. Tag documents by client, engagement and permission level, filter retrieval at query time, and keep separate workspaces where a firewall is required. Never allow cross-client retrieval unless both sides have approved it.

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 the AI governance framework for related deployment and control detail.

Rollout and human oversight

Pilot on published methodology and marketing material before touching client-confidential content. Build a labelled question set with engagement managers and subject specialists, 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 client-facing 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 consulting firms 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 partners access our engagement knowledge?

Only if you configure it. Keep per-client workspaces and role-based filters, and treat cross-engagement retrieval as an explicit, approved exception.

How do we retire outdated methodology decks?

Version documents and re-embed on update, then expire superseded versions so retrieval cannot return obsolete guidance.
