Rigorous model analysis, inside Excel.

Every formula checked. Every assumption surfaced. Every dependency mapped. Systematic analysis and AI-assisted insights — at a fraction of the cost of a manual review, in minutes.

Kalc Excel add-in analysing a project finance model with severity-ranked findings

Three layers of intelligence. One clearer picture.

Kalc applies systematic checks first, AI-assisted insights second — so every finding is traceable to a cell, not a guess.

Systematic checks

Every formula reconstructed from source. Every dependency mapped. Structural clarity before AI adds context.

Actionable output

Assurance score, severity-ranked findings, and an exportable analysis report — ready for your working papers and presentations.

From raw model to informed next step

Understand

Structure mapped. Dependencies traced.

Validate

Formulas checked. References flagged.

Interpret

Logic assessed for purpose.

Prioritise

Findings ranked by severity.

Share

Exportable report for your review.

Model completion is not decision confidence

LLMs produce probable answers

Financial models are computation graphs, not text. A language model describes what a formula likely does — it cannot reconstruct every path and prove correctness.

Specialist review is hard to scale

The thorough model review you want before sharing a workbook is slow, expensive, and inconsistently documented — especially when timelines are tight.

Evidence gets buried

Findings scattered across chat transcripts, email threads, and verbal sign-off. Teams need cell-level references, severity scores, and a reproducible analysis record.

Systematic analysis in one workflow

Structural checks, AI-assisted insights, and exportable findings — applied in sequence inside Excel.

Systematic checks

Every formula reconstructed from source. Every dependency mapped. Every broken reference traced — structural clarity before AI adds context.

AI-assisted insights

Sector-aware logic checks on verified structural data — DSCR, IRR, NPV, covenant patterns — explained with cell-level references.

Assurance scoring

Model-wide assurance score with severity-ranked findings. Critical, high, medium, and low — grouped for remediation, not buried in noise.

Structure mapping

Complete dependency graph across sheets — orphaned cells, broken external links, and fragile points mapped before a single finding is raised.

Version comparison

Side-by-side model versions with cell-level change tracking and impact analysis — built for revision cycles and stakeholder updates.

📄

Exportable report

Analysis report formatted for working papers, presentations, and internal review — timestamped and traceable to source cells.

The agent builds. Kalc verifies.

AI can build a financial model in minutes — but it can't independently check its own work, and neither can the copilot that helped write it. Kalc is the independent check in the loop: deterministic verification and findings your agent can act on. Kalc identifies issues and suggests remediation; it does not advise on legal, financial, or other matters.

Verify in the loop

Call Kalc from your agent over API or MCP. Every formula, dependency, and financial-logic rule checked deterministically — not guessed. Findings anchored to the exact cell.

Findings your agent can act on

A remediation brief written for a build agent to read: what to change, where, and why — grouped by severity. Your agent fixes and resubmits; Kalc reports what resolved, what's still open, and what regressed.

  • POST /sessions — submit a version, get findings, deltas, and a gate status your orchestrator can branch on.
  • GET /audit/{id}/brief.md — an agent-ready remediation brief, ready to paste into your build agent.

Available over REST and as an MCP server. Kalc verifies; it never builds. Findings identify and suggest — they are not legal, financial, or professional advice.

Confidential by architecture — not by policy

🇪🇺

EU-hosted data

All model analysis processed and stored within EU infrastructure. No transatlantic transfers of your deal data.

🔒

Zero AI retention

Zero data retention on AI inference. Your formulas are analysed to produce findings — not stored or used for training.

⚖️

GDPR Article 28

Data processing agreement available. You remain the controller; Kalc acts as your processor.

Separate from authorship

Kalc did not build your model and cannot edit it. It identifies issues and suggests remediation — analytical support only, not legal, financial, or professional advice. You decide how findings are used.

Frequently asked

What does Kalc analyse? +

Excel financial models — formulas, dependencies, assumptions, and financial logic. Kalc reconstructs every calculation path, applies sector-specific checks, and returns severity-ranked findings with cell-level evidence directly inside Excel.

How is this different from ChatGPT or Copilot? +

Language models produce probable descriptions of formulas. Kalc applies systematic checks first, then AI-assisted insights — with cell-level references you can review. Kalc did not build your model.

Where is my data processed? +

On EU infrastructure. Zero data retention on AI inference is available. Self-hosted and air-gapped deployments are supported for regulated environments.

What is included during beta? +

Full access to all analysis layers at no cost. Direct support from the Kalc team. We request first impressions within fourteen days of your first analysis.

Which sectors are supported? +

Project Finance, M&A, Infrastructure, and Real Estate templates are in active beta. General financial logic checks apply to all models regardless of sector.

Every model deserves a second look.

Systematic analysis at machine speed — a fraction of the cost of a manual review.
