The verdict in three sentences
In 2026, an internal AI document-search assistant costs 15,000 to 50,000 EUR and ships in 2 to 4 months. Built on a secure RAG architecture, hosted in the EU with access controls, it lets your teams query thousands of documents in natural language and cuts information-search time by about 40 %. Its value comes not from the model but from strictly respecting each user's confidentiality and access rights.
Why not a consumer tool
Consumer AI assistants are tempting but raise three problems in an enterprise: documents may transit outside the EU, access rights are ignored (an employee sees what they shouldn't), and there is no traceability. An internal assistant solves all three.
The central challenge is segmentation: the assistant must only return documents a given user is entitled to see. This requires tying each document to its permissions and filtering the search accordingly.
| Enterprise requirement | Consumer tool | Dedicated internal assistant |
|---|---|---|
| Data hosting | May be outside EU | EU guaranteed |
| Access-right enforcement | No | Yes, per user |
| Query traceability | No | Logged |
| Cited sources | Variable | Systematic |
| Contractual confidentiality | Weak | Enforced |
Use cases and time savings
Gains concentrate in roles where information is scattered: legal, technical, sales, HR. Here are 2026 orders of magnitude per use case.
| Use case | Search time before | With assistant | Gain |
|---|---|---|---|
| Find a contract clause | 25 min | 4 min | -84 % |
| Answer an RFP | 6 h | 3.5 h | -42 % |
| Find a technical procedure | 18 min | 5 min | -72 % |
| Prepare a sales pack | 4 h | 2.4 h | -40 % |
| Onboard a new hire | 12 h | 7 h | -42 % |
Across a varied case mix, the weighted average lands around -40 % of search time, which, for 50 employees spending 5 h/week looking for information, frees roughly 100 hours per week.

Mini case study
Mehdi, CIO of a 60-person consulting firm in Paris, finds his consultants spend on average 5 hours a week hunting for deliverables, methodologies and past references. Kolonell deploys an EU-hosted RAG assistant with per-team segmentation for 34,000 EUR and 500 EUR/month. Measured gain: -40 %, i.e. 2 hours per consultant per week. Across 45 consultants billed at 90 EUR/hour, valuing even half the time as billable, the annual gain exceeds 180,000 EUR. Payback lands in under 4 months.
FAQ
Do our confidential documents stay private? Yes. Hosting is in the EU, documents are not used to train a third-party model, and the assistant enforces each user's access rights. Every query is logged.
How long to deploy? Expect 2 to 4 months depending on document volume and access-right complexity. Connecting the sources (SharePoint, Drive, DMS) and segmentation are the bulk of the effort.
Which formats does it handle? PDF, Word, Excel, presentations, intranet pages and archived emails. Scanned documents need an OCR module, which can be added to the project.
What does maintenance cost? Expect 400 to 900 EUR/month for hosting, reindexing new documents and monitoring. Since documents remain your property, there is no vendor lock-in.
Can it be wrong? It systematically cites its sources so you can verify. Configured to answer only from retrieved documents, it declines when the information doesn't exist rather than inventing it.
