BUILT FOR TEAMS WHO CAN’T AFFORD TO MISREAD THE SPEC
Stop playing “Ctrl+F roulette” with specs and contracts.
Phyxius is a forensic search tool for project documents. Upload specs, contracts, RFIs, and addenda. Ask in plain language. Phyxius finds the exact clause, shows the paragraph, and links you straight to the source — whether you’re at your desk, in the trailer, or out in the field.
Private by design • Works on desktop, tablet, and mobile • Source link on every answer • Auto-generated document manifests (coming soon)
Example question
“What’s the compaction requirement for backfill under the pump pad in Area C?”
Found in Area_C_Sitework_Spec_31_23_23.pdf — open source (p.12 §3.5.2)
Why we built Phyxius
Fixed-cost projects leave no room for “I think the spec meant this.” One missed line in a 400-page document can burn margin, trigger rework, or stall a job.
Most tools try to be “intelligent.” Phyxius is deliberately uncreative. It doesn’t brainstorm, draft, or guess. It finds the exact text, shows the source, and keeps every project workspace separate.
For project managers, engineers, and superintendents who live under the spec — in the office, trailer, or field — accuracy isn’t optional. It’s the job.
Built for teams where precision matters more than opinions.
Who it’s for
-
Project Managers
Coordinate scope, schedule, and budget — and need to confirm exactly what the spec and contract say before approving anything. -
Engineers (Civil, Marine, Structural, Mechanical, etc.)
Write and interpret technical requirements, and need to locate, defend, and clarify exact language quickly. -
Superintendents & Field Leads
Make calls in the field and need answers they can pull up on a tablet or phone, with the clause to back it up.
How it works
Three steps. No training, no prompts, no “AI wizardry.” Just faster answers from the documents you already have.
1. Drop in your project documents
Specs, contracts, RFIs, addenda, SOPs — organized into a separate workspace for each project or client.
2. Ask in plain language
“What’s the allowable settlement for the tank foundation?”
“What coating system is specified for the piles?”
“When are schedule extensions allowed on this contract?”
3. Open the exact source
Phyxius points you to the page and paragraph it used. Click once to open the original PDF and verify it yourself — on desktop, tablet, or mobile.
No drafting. No summaries you can’t trust. Just source-linked answers from your own documents — wherever you’re working.
What Phyxius catches for you
It’s not about “searching documents.” It’s about defending decisions, avoiding RFIs, and protecting margin.
Hidden “gotchas” in specs
Find buried exclusions, conflicting requirements, and “unless otherwise noted” clauses before they become change orders.
Critical technical details
Locate pressure ratings, coating systems, tolerances, testing requirements, and acceptance criteria instantly across documents.
Dispute & claim support
When a question turns into a dispute, pull up the exact clause and highlight it from the original source in seconds — even from the field.
Trust & Security
Built for teams who care about confidentiality, clean data boundaries, and predictable costs.
Your data stays in your workspace
Each project or client has its own workspace. Documents don’t leak between them, and nothing is shared with other customers.
No training on your documents
Phyxius indexes your files for search only. Your content is never used to train public AI models.
Read-only by design
Your original documents never change. Phyxius reads them, indexes them, and lets you open them — that’s it.
Predictable usage, no bill shock
Built-in circuit breakers cap AI answers on free trials and Starter plans so you never get surprise usage invoices.
