CostLogic is a construction takeoff and job-costing workspace with a powerful agent called Onyx. Onyx can perform actions on your behalf. Upload plans, detect rooms, calibrate scale, measure quantities, turn takeoffs into estimates, and send invoices, all in one browser-based workflow. Go from blueprint to invoice without stitching together five different tools, and turn days into hours or minutes of work.

CostLogic is a browser-based construction takeoff and job-costing workspace that connects measurement, estimating, and invoicing in one continuous workflow. Instead of juggling separate tools for reading plans, calculating quantities, pricing jobs, and billing customers, CostLogic brings the entire process into a single interface. At its core sits Onyx, an AI assistant that can detect rooms on floor plans, draft estimates, prepare invoices, and answer questions about your projects—all through natural language prompts.
Onyx acts as a built-in project assistant that understands construction plans and job data. You can ask it to detect rooms on a floor plan, turn a takeoff into an estimate, draft an invoice, or check a bid's margin—and it performs those actions directly in your workspace.
Upload construction PDFs and measure linear, area, count, and angle quantities directly on the drawing. The scale is calibrated automatically from the title block, and multi-page plans are named and organized for you.
Instead of manually tracing every wall, Auto Room identifies rooms and areas straight from the drawing. Once detected, those spaces can be turned into measured quantities that flow into your estimate.
Measured quantities move directly into line items with markup, waste, tax, and deposits included. An approved estimate converts into an invoice in one click, which you can email as a branded PDF and track as outstanding.
One tool from first measurement to final invoice—no exporting, no retyping, no stitching five apps together.
Most takeoff software stops at measurement, forcing you to export quantities into a separate estimating tool and then into an accounting system. CostLogic collapses that chain into a single browser-based workflow. The Onyx assistant adds another layer of efficiency by handling the tedious parts—room detection, estimate drafting, invoice preparation—so you can focus on the actual job. It also runs entirely in the browser on Mac and PC, with published pricing and no sales call required to get started.
You're tired of re-entering quantities across multiple tools, or you want AI to handle the repetitive parts of takeoff and billing. If you measure plans, price jobs, and send invoices on a regular basis, CostLogic offers a streamlined alternative to the traditional takeoff-software-plus-spreadsheet approach. The free trial and transparent pricing make it easy to test whether the workflow fits your operation.

Bob's CLI runs on your own hardware with zero API costs, zero data leaving your machine. Bob lives in your terminal, sees your actual files, and writes code only with your explicit approval. What makes it different: auto-detect local AI models, behavioral DNA profiling that adapts to how YOU work, autonomous code review + auto-fix, conversation forking, deep dives, and SovereignLink — remote execution from any device while your code stays home. Free to start. Sovereign by design.
GitHits gives coding agents access to the open-source code your app depends on. Get real implementation examples, dependency source navigation, package inspection and documentation. Agents can grep and read your codebase. They can't grep and read the open-source code your app depends on. That's where they start guessing, retrying, and looping. GitHits builds a version-aware index on demand. Agents can search, navigate, and inspect the code behind their dependencies. CLI: npx githits@latest init
