The Best Glean Alternative for Engineering Firms and Mid-Size Companies (2026)
AI Document Search • Updated September 2026
Short answer for engineering firms: Corpus by SalemWise. It searches drawings, specs, calc packages and geotech reports (scanned sheets are OCR’d as part of setup), cites the document and page on every answer, and works in the browser, or Microsoft Teams connected during setup, on your hardware (a local NVIDIA GPU) or ours. Setup from $21,000, ongoing $1,500–$2,000/mo, no per-user fees, live in 6–8 weeks.
Glean is a powerful platform. Third-party buyer reports (Vendr, GoSearch, as of March 2026) put it at about $60,000 a year at minimum, before the mandatory support surcharge and the paid proof-of-concept. If that closed the tab for you, this guide covers what to do instead.
Every week, knowledge workers at mid-size companies lose nearly a full day searching for documents that already exist somewhere in their organization. Past reports, contract clauses, project specifications buried in SharePoint, Google Drive, or a file server that nobody can navigate.
Glean is the best-known solution for this problem — an enterprise AI search platform valued at $7.2 billion as of mid-2025. It works well for the organizations it was designed for. The issue is that most mid-size companies are not those organizations.
This guide covers how much Glean actually costs, why its pricing model creates a wall for most mid-size buyers, and which alternative delivers the same core capability without the enterprise price tag.
How Much Does Glean Cost? (2026)
Glean does not publish its pricing. That alone tells you something about who it was built for. All figures below come from third-party reports — Vendr, GoSearch, and Sacra — not from Glean directly.
According to Vendr and GoSearch, Glean's minimum annual contract starts at approximately $60,000 per year, requiring roughly 100 users at $50–65 per user per month. Sacra reports typical initial contract values ranging from $100,000 to $500,000 per year for larger organizations.
At the minimum contract, you are looking at roughly $66,000/year all-in (base plus mandatory support), before any POC costs. Glean was built for organizations with 500+ employees, dedicated IT teams, and multi-month procurement cycles. The document search problem, though, does not only exist at that scale.
Why Glean Does Not Fit Most Mid-Size Companies
A 50-person engineering firm with two terabytes of project files has the same information retrieval problem as a 5,000-person corporation. So does a 30-person law firm with decades of contracts, or any growing company with a document library that existing search tools cannot navigate.
IDC research found that employees fail to find the information they need 44% of the time. McKinsey (2012) estimated knowledge workers spend 9.3 hours per week — nearly 20% of their work week — searching for information that already exists. At a fully loaded cost of $75/hour, a 100-person team losing 3 hours per week to failed searches (our assumption) burns roughly $1.17 million per year.
Most companies dealing with this do not have a six-figure AI software budget, a 6-month procurement cycle, or a dedicated IT team to stand up an enterprise platform. Glean is a well-built product. It is just the wrong price tier for this buyer.
The Best Glean Alternative: SalemWise Solutions
SalemWise Solutions gives engineering firms page-cited search over their own archive, in the tools your team already uses (the browser, or Microsoft Teams connected during setup) at a price point built for companies without enterprise procurement budgets.
SalemWise was founded by Yermek Ibray, a software engineer with 16+ years of experience, including roles at Google and Meta, specifically to solve this problem for the organizations that Glean's pricing leaves behind. The engineering team includes alumni from Facebook, the New York Times, and Stash — engineers who have built large production systems.
How It Works
-
01Bring your project PDFs PDFs, including scanned ones: reports, specifications, contracts, as-built drawings. The pilot works from a copy. In a full deployment, we connect Corpus to your network drive, SharePoint or ProjectWise as part of setup, and scanned PDFs are OCR'd as part of setup.
-
02Ask a question in plain English In the browser, or in Microsoft Teams connected during setup, wherever your team already works. "What were the payment terms in the Anderson contract from 2021?" No syntax. No folder navigation.
-
03AI searches your full document history The system understands intent and finds the most relevant content across your entire document library — including cases where the exact words in your question do not appear in the document.
-
04Get a specific, auditable answer Document name, page number, and section reference. Every answer links back to the original source. Not a vague pointer to a folder. A result you can show your client.

Who This Is For
The firms this fits are not defined by company size. Their teams have stopped trusting internal search and work around it instead.
Engineering Firms
Corpus is built for engineering firms — civil, structural, geotechnical, environmental, surveying and mining — with terabytes of project documentation, design calculations, as-built drawings, and lessons-learned reports spread across SharePoint and file servers.
For engineering firms specifically, SalemWise also addresses one of the highest-stakes knowledge risks in the industry: what happens when a senior engineer retires. Decades of project knowledge walk out the door unless it has been captured and made searchable.
Law Firms
Corpus is built for engineering archives, but the same page-cited search fits a law firm's contracts, case files and regulatory filings, where the clause matters more than the document.
Professional Services Firms
If one or two people are the firm's search engine, because the documentation is impossible to navigate, Corpus is built to make what they know findable by the whole team. If your organization has one person who "remembers everything," consider what happens to that knowledge when they leave.
Your Data Stays Where You Put It
With SalemWise, you choose where your data lives: hosted by us, or on local GPU processing using NVIDIA hardware on your own network, where your documents are indexed and queried without leaving the building. Either way, Corpus runs an open-weight model and no document content, query text or results go to a public AI API.
This is not a premium add-on. It is included in the standard offering.
The ROI Math on Broken Document Search
Take a team of 100 knowledge workers at an average fully-loaded cost of $75/hour. If each person loses 3 hours per week to failed searches (our assumption, not a measured result; well under McKinsey's 2012 figure of 9.3 hours a week), that adds up to $1.17 million per year in lost productivity.
A 10% improvement in search efficiency saves roughly $117,000 per year for that team. Against a first year of about $39,000–$45,000 (setup from $21,000 plus $1,500–$2,000/mo), that pays back in roughly four to five months.
Standard deployment: setup starting at $21,000 and ongoing $1,500–$2,000/mo.
Common Objections
"We already have Microsoft Copilot."
Microsoft Copilot is a general-purpose productivity assistant for the Microsoft 365 ecosystem. It was not designed to search and synthesize large libraries of legacy PDFs and engineering documents. It cites what Microsoft Graph has indexed: Microsoft 365 content plus any Copilot connectors your IT team sets up. Legacy network drives, ProjectWise vaults and scanned sheets without a text layer are often outside that index. SalemWise is purpose-built for document-heavy organizations that need precise, verifiable answers from their own file history. Copilot helps you write emails faster. SalemWise finds the answer that already exists in your documentation.
"We can just improve our SharePoint search."
SharePoint's built-in search uses keyword matching. It breaks down with large document libraries, specialized terminology, and deep folder structures because it looks for exact words rather than meaning. An engineer searching for "soil bearing capacity results from the Henderson site" will get zero results if the document uses "subgrade pressure testing data" instead. AI document search understands intent and finds relevant answers even when the words don't match verbatim.
"What about implementation risk?"
Start with a free 30-minute call, then a $5,000 fixed-price pilot on one real pursuit, credited toward setup. Scope and final pricing for the full deployment are confirmed in writing after we review your actual document environment, not before. No 100-user minimum. Standard deployment takes 6 to 8 weeks.
"We're concerned about our data leaving our network."
Local GPU processing is a standard option, not an upgrade. Your documents and queries stay on your infrastructure. Nothing is sent to external APIs. Available at the standard pricing tier — setup starting at $21,000 and ongoing $1,500–$2,000/mo.
Frequently Asked Questions
How much does Glean cost in 2026?
Glean does not publicly list its pricing. Third-party sources — Vendr, GoSearch, and Sacra — consistently report minimum annual contracts starting around $60,000/year, requiring roughly 100 users. Typical contracts range from $100,000 to $500,000/year. Additional costs include a mandatory support fee (~10%) and paid proof-of-concept engagements. Contact Glean directly for current pricing.
Is Glean too expensive for mid-size companies?
Glean was designed for large enterprises with 500+ employees, six-figure software budgets, and multi-month procurement cycles. For companies outside that profile, the pricing structure creates a significant barrier: 100-user minimum, mandatory support surcharge, and in many cases a paid proof-of-concept before seeing any results.
What is the best Glean alternative for smaller companies?
SalemWise Solutions delivers page-cited AI document search in the browser, or Microsoft Teams connected during setup, with setup starting at $21,000 and ongoing $1,500–$2,000/mo. No per-user fees, no minimum headcount; the $5,000 pilot is credited toward setup. Learn more at salemwise.com.
Why is SharePoint search not working for our documents?
SharePoint's built-in search uses keyword matching. It breaks down with large document libraries, specialized terminology, and deep folder structures. AI document search understands intent and finds relevant answers even when the words don't appear verbatim in the document.
How is SalemWise different from Microsoft Copilot?
Microsoft Copilot is a general-purpose productivity assistant for Microsoft 365. It was not designed to search large libraries of legacy PDFs.
