Built for drawing-heavy estimating and quoting teams
Unlock capacity and eliminate the quoting bottleneck
Offline CAD & drawing takeoffs
Analyse drawings and extract linear, area, and count quantities directly on-device. Supports 2D drawing sets (DWG, DXF, PDF, TIFF), 3D CAD models (STEP, IFC), and BOM context without cloud uploads.
Zero-setup CRM & RFQ inbox
Organise incoming requests from Gmail, Outlook, EML, MSG, or ZIP archive packages. Create structured RFQ folders and extract sender contacts with zero account friction.
Import wizard for cost libraries
Migrate rate cards, material catalogues, and historic estimates from Excel/CSV files in minutes. Automatically maps custom tooling setups, nesting margins, and local labour codes.
AI-assisted draft estimating
Turn messy drawings, BOMs, spreadsheets, and spec sheets into structured Bills of Quantities (BOQ). Generates reviewable itemised drafts while keeping the estimator in full control.
Local-first data sovereignty
Keep proprietary customer designs, company margins, and bid history isolated on-disk. Kwantflow does not send quote files or prompts to third-party AI providers.
Seamless background updates
Get non-disruptive local updates. One click keeps your desktop CAD viewer, geometry converters, and estimating engines compatible with the latest industry formats.
