How it works

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.

A thorough external review follows a defined process — scope, iterations, and a professional conclusion. Kalc runs the systematic verification pass inside that workflow: before the pack leaves, between cycles, and after every material change.

∑

Systematic checks

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

◎

AI-assisted insights

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

✓

Actionable output

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

The analysis flow

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.

The problem

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.

What you get

Systematic analysis in one workflow

Formulas, assumptions, statements, and scenarios — structural checks, AI-assisted insights, and exportable findings in one Excel workflow.

  • Severity-ranked findings with cell references — an independent verification pass before external model assurance review
  • Statement and scenario assurance where your model presents them: structural ties, roll-forwards, and which case is live
  • Reliance signals, documentation coverage, and an exportable analysis record for working papers

Why verification capacity is the constraint in 2026 →

∑

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.

▤

Financial statement checks

P&L, balance sheet, and cash flow detected where the model presents them — designed to help you see whether statements tie, roll forward, and hold together.

◫

Scenario provenance

See which case the workbook was saved on, how cases differ, and which drivers move — before covenants and metrics are read on the wrong case.

☰

Documentation & governance

Assumption coverage and reliance signals — designed to show whether the model is checkable before external review.

Built for your work

Verification that fits how you already work

Guides for modellers and compliance reviewers — and a workflow that extends formal review, not replaces it.

For modellers →

First verification pass, assumptions, Zero Retention, and when to escalate to human review.

For compliance reviewers →

Data handling, Contained vs Grounded, GDPR rights, and a review checklist.

Practitioner guides →

Assumptions documentation, pre-decision verification, and how Kalc fits your workflow.

Extends your review workflow

Read the guide →

Before external review

Fix clear defects and arrive with a severity-ranked findings summary for your reviewer.

During iteration

Re-run after material edits; see what resolved and what regressed between versions.

Between engagements

Maintain baseline model hygiene when a full review is not yet booked.

Complements build tools

Build and verify →

Copilots draft

Verify reconstruction and consistency after drafting — in the same workbook.

Agents populate

Receive agent-ready findings; fix and re-verify in the loop via API or MCP.

You decide

Kalc verifies; it never builds. Findings identify and suggest — you choose what to fix.

For AI-built models

The agent builds. Kalc verifies.

AI can build a model in minutes — but it cannot independently check its own work. Kalc is the separate verification step: deterministic findings your agent can act on via API or MCP.

⟳

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 for your build agent: what to change, where, and why — grouped by severity. Re-submit and see what resolved or regressed.

Built for agent workflows
  • 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 for your build agent.

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

Confidential by architecture — not by policy

EU-hosted processing

Model analysis runs on EU infrastructure. No transatlantic transfers of your deal data are described in our published Privacy Notice.

Analysed in memory. Never stored.

Your model is analysed in memory and never written to our storage. Nothing is written to disk, nothing is backed up, nothing is kept beyond the run — and no AI provider we use trains on it.

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. Kalc verifies and recommends; you remain responsible for the analysis.

Questions

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.

How does Kalc fit with external model review? +

Kalc is designed as a preparation and follow-up layer around the review you already use — run passes between meetings, fix clear defects early, and arrive with a findings summary. It does not sign off models or replace a qualified external reviewer. Read how they work together →

Where is my data processed? +

On EU infrastructure. Your model is analysed in memory for the duration of the run. You can use Zero Retention so nothing from the analysis is stored after it finishes. New workspaces default to Contained — nothing about your model is sent to a third party unless you opt in to Grounded advisory features. See our Privacy Notice.

What is included during beta? +

Full access to all analysis layers at no cost for 30 days from your first analysis, extendable on material contribution — see our Beta Terms. Direct support from the Kalc team. We request first impressions within fourteen days of your first successful run.

Which sectors are supported? +

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

Every model deserves a review.

Kalc gives your team the audit capacity to get there — in minutes, inside Excel.
