Corpus - 2026 Pricing, Features, Reviews & Alternatives

Corpus indexes an organization's full document library across SharePoint, Google Drive, Dropbox, OneDrive, and local file servers, then answers plain-English questions through Microsoft Teams, Slack, or WhatsApp. Every response includes the source document name, page number, and section reference, producing results that are auditable and client-presentable without additional formatting. Engineering-grade OCR extends coverage to scanned PDFs, and intent-based retrieval surfaces relevant content even when query terms do not appear verbatim in the document.

Corpus is configured for industry-specific vocabulary, supporting terminology and standards frameworks such as AASHTO, ACI, AWWA, MasterFormat, IBC, and ASCE for engineering verticals. This domain tuning improves retrieval accuracy over general-purpose AI search tools operating on the same document sets. Indexed file types include Word documents, PDFs, reports, specifications, contracts, as-built drawings, and scanned files. Data residency options cover cloud deployment or a local GPU installation where data remains on the organization's own network. Setup and deployment complete in 6 to 8 weeks.

Primary target markets are engineering firms (civil, mining, structural, oil and gas, and environmental), law firms, professional services firms, government agencies, and prime contractors with 20 to 500 employees managing document libraries their teams can no longer navigate effectively. Pricing is flat-rate from $1,800 per month with no per-user fees and no minimum headcount requirements. A free data audit is available before any financial commitment.
