AI CONSTRUCTION ESTIMATOR · PRIVATE BETA 2026
bidyou.ai is an AI construction estimator with a specific architecture choice: each tenant gets a private embedding store of their historical bids, queried locally, on EU-owned GPUs, with provenance preserved on every prediction. Two contractors using bidyou.ai see different recommendations because they had different histories. Generic AI estimators give them the same answer; we don\'t.
Built for the EU and English-speaking construction markets. Free for three active projects. No credit card. No third-party LLM API ever sees your bids.
Most AI construction estimators ship a single model fine-tuned once on a public dataset. Two contractors using the same tool get identical recommendations because the model is identical. bidyou.ai gives each tenant a private embedding store of their historical bids. Your matches come from your closed projects first, not from generic priors. Two contractors using bidyou.ai see different recommendations because they had different histories.
Generic AI estimators send your BoQs to OpenAI, Anthropic, or a managed LLM endpoint. Even with "no training" toggles, your data crosses the wire. bidyou.ai runs Qwen3 family models on owned EU GPUs. Zero third-party API calls. Your bids stay inside the EU perimeter, full stop. GDPR-native architecture, signed DPA on Pro and above.
Hover any AI suggestion → see exactly which historical line it matched, which drawing block it counted, the source dates, the confidence score. Generic AI tools tell you "here is your estimate." bidyou.ai tells you "here is your estimate, and here are the 23 prior bids it came from, and here is why this line's confidence is 87% not 95%."
Every line your estimator accepts, edits or overrides is logged with reason. The text dictionary refreshes weekly (130k+ mappings, 75% top-1 accuracy at baseline). Sister-tables (lpr_excel_ia, orc_item_ia, obras_ia_metricas) capture AI predictions in parallel to production for backfill comparison and model versioning. Your engine gets smarter with use; theirs doesn't.
~15 funded entrants in the last 24 months. Most are US. Most train one global model. Only Kreo (UK) has any meaningful EU positioning, and even Kreo doesn\'t do per-tenant historical bid training. Here\'s where each cluster sits, and where bidyou.ai differentiates.
Their angle: Quantity takeoff from drawings. 97% claimed accuracy. Strong US adoption.
Gap that opens room for bidyou.ai: No European retailer pricing. No private supplier lists. No EU hosting.
Their angle: Only credible EU-rooted AI estimator. Strong drawing takeoff. Real UK customer base.
Gap that opens room for bidyou.ai: UK-centric construction taxonomy. No multilingual ingest. No private supplier-list integration.
Their angle: AI-first UX. Free trials. Recent funding. Aggressive marketing.
Gap that opens room for bidyou.ai: US training data. No GDPR DPA out of box. No EU billing. Workflow optimised for CSI MasterFormat, not BoQ.
Their angle: Bid-finding + estimating combined. Useful for contractors hunting work.
Gap that opens room for bidyou.ai: Estimating quality varies. Often coupled to specific marketplaces. Less audit-grade than EU compliance buyers require.
Common pattern: US-trained models, generic priors, third-party LLM endpoints, no GDPR DPA out of box. bidyou.ai\'s opening: EU/GDPR-native, per-tenant private model, sub-€100/mo, multilingual ingest.
Excel BoQs (any layout), PDF specs (text or scan), DXF/DWG drawings (YOLOv11 block detection). EN/PT/ES/FR all read natively. No template lock-in.
Dictionary lookup against your historical bid corpus (75% top-1). For un-matched lines, vector search across hundreds of thousands of historical items via per-tenant ChromaDB. Confidence scored, provenance preserved.
Your private supplier price lists queried first. Live retailer queries (region-aware) for items not in your catalogue. Ranked by total cost delivered (unit + shipping + lead time + stock risk).
Every accept/edit/override is logged with reason. Sister-tables capture AI vs human deltas without touching live data. The text dictionary refreshes weekly. Continuous-learning loop closes when finished jobs feed actual cost back.
An AI construction estimator is software that uses machine learning to convert construction inputs (drawings, BoQs, specs, photos) into priced bid estimates. It typically combines computer vision (for drawing takeoff), natural language processing (for spec parsing), and retrieval-augmented generation (for matching against historical bids or price databases). bidyou.ai falls in this category but with a specific approach: per-tenant training on YOUR historical bids rather than a single global model.
Top-1 dictionary match accuracy is around 75% across the baseline 130k+ multilingual mappings. Semantic fallback (768-d sentence-transformers, mpnet multilingual) catches another layer. Confidence is reported per-line. Low-confidence lines are flagged for human review. Accuracy improves continuously as your tenant's historical corpus grows — by month 3 of active use, most contractors see 85%+ top-1 on their own item descriptions.
Three reasons. First, generic LLMs don't have your historical pricing — they hallucinate or quote stale public-web prices. Second, they don't do quantity takeoff from drawings (no YOLO/computer-vision pipeline). Third, GDPR: your BoQs are commercially sensitive; sending them to a US-hosted LLM is a data-residency violation in most EU jurisdictions. An EU-hosted estimator with private supplier lists, local inference, and per-tenant history isolation is the only architecture that handles all three.
Qwen3 family models running locally on owned EU GPUs (NVIDIA RTX 5070 Ti and 5090 series). Multilingual sentence-transformers (mpnet, 768-d embeddings) for vector search. PaddleOCR for scanned-document text extraction. YOLOv11 for drawing block detection. All inference is local — zero third-party LLM API calls, zero data egress.
Togal and Kreo are strong on quantity takeoff from drawings; Beam and Handoff focus on AI-generated estimate drafts. None ship per-tenant model training on your historical bids — that's bidyou.ai's wedge. None offer integrated live retailer pricing for BoQ items. EU/GDPR positioning is unique to bidyou.ai. Pricing also undercuts: sub-€100/mo cloud SaaS vs. their $99–$299 range.
Private beta open now for English-speaking markets (UK, IE, US, AU, CA). Free tier (3 active projects, no credit card) lets you try the matching against the seed database immediately. Public launch with multi-currency, multi-tax-regime, and additional language coverage (DE/FR/ES rolling out) follows during 2026. Founding-customer pricing locks in for early adopters.
Free forever for 3 active projects. No credit card. Magic-link activation. EU-hosted.
