The verdict in three sentences
An internal AI assistant does not replace your documentation: it makes it queryable in natural language, with source citation. Budget SGD 22,000 to 58,000 in 2026 for a secure RAG assistant hosted in-region, with access control. The 20-40 % gain on search time pays off fast once 30 to 50 staff use it daily.
What a secure RAG assistant does
RAG (retrieval-augmented generation) ingests your documents, indexes them, then answers while citing sources. Access control ensures each person sees only what they are entitled to. Here are the 2026 tiers.
| Tier | Cost (SGD) | Sources ingested | Access control | Timeline |
|---|---|---|---|---|
| Basic | 22,000 - 32,000 | 1-2 (drive, wiki) | Global | 6-8 weeks |
| Standard | 32,000 - 46,000 | 3-5 (+ ERP, email) | Per role | 8-10 weeks |
| Advanced | 46,000 - 58,000 | 5+ (+ business systems) | Per document | 10-12 weeks |
The standard tier covers most SMBs: ingestion of several sources, role-based access control and compliant in-region hosting.
Cost vs search hours saved
The decisive calculation compares project cost to the time your teams spend searching for information. In 2026, an employee spends on average 4 to 6 h/week searching documents or asking internal questions.
| Employees | Search hrs/week | 30 % gain | Hours saved/month | Value/month (SGD 50/h) |
|---|---|---|---|---|
| 20 | 5 h | 1.5 h | 130 h | SGD 6,500 |
| 40 | 5 h | 1.5 h | 260 h | SGD 13,000 |
| 80 | 5 h | 1.5 h | 520 h | SGD 26,000 |
| 150 | 5 h | 1.5 h | 975 h | SGD 48,750 |
From 40 employees, a standard assistant at SGD 40,000 pays back in 3 to 4 months, hosting included.
Mini case study
Wei Ling, MD of a 60-person manufacturing SME in Singapore, finds her teams lose time searching quality procedures, datasheets and contract clauses. She deploys a standard RAG assistant for SGD 40,000 + SGD 1,000/month (in-region hosting + access control). Real gain: 30 % on 5 h of weekly search, about 390 h saved per month across 60 people. Valued at SGD 50/hour, that is SGD 19,500/month of productivity. The project pays back in a little over 2 months.

FAQ
Why is RAG safer than a classic chatbot?
RAG answers only from your documents, with source citation, which limits hallucinations. Access control ensures no one sees a document outside their scope.
Where is my data hosted?
In-region, on dedicated infrastructure, with a model that does not train on your data. That is the compliance condition; budget SGD 300-850/month for compliant hosting and access control.
How long to deploy?
From 6 to 12 weeks depending on the number of sources. Ingestion and document cleanup are the longest task, not the model itself.
What time gain to expect?
Between 20 and 40 % on document search in 2026. ROI depends mainly on the number of active users and the quality of your source documentation.
Do I need to tidy my documentation first?
Some structure helps, but the assistant absorbs heterogeneous sources. A first project can include targeted cleanup of the most-consulted documents.
