01 / How it works

Four prompt stages.
One audit-ready workbook.

Auditably runs your raw climate data through a structured AI pipeline aligned with the 69 paragraphs of IFRS S2 — producing a multi-sheet Excel workbook that ties every cell back to a paragraph reference.

STEP 01

Cleanse your data

Drop in raw meeting notes, spreadsheets, ERP exports — whatever your sustainability team already produces. Our AI Cleanser turns it into the four canonical CSVs IFRS S2 expects.

STEP 02

Build the master prompt

One click generates the structured master disclosure prompt — pre-loaded with your entity, sector, fiscal year, and all four data inputs. Send it to ChatGPT, Claude, or our Auto-API pipeline.

STEP 03

Generate the workbook

Paste the AI response back in — or let Auto-API run end-to-end — and download a 6-sheet Excel workbook with cover page, intake data, physical & transition risks, glossary, and full TCFD narrative. Ready for your auditor.

Persefoni-grade output.
Without the Persefoni invoice.

03 / Why finance teams choose us

Audit-ready disclosures,
without the consulting bill.

We replaced a six-week consulting engagement with a one-afternoon Auditably session. Our auditor signed off on the workbook structure on the first review.

05 / FAQ

Everything finance leaders
ask before buying.

Is the Excel output actually audit-grade? +
Yes. The workbook follows the structure assurance providers expect under ISAE 3000 (Revised): every metric ties back to an IFRS S2 paragraph reference, every risk has a unique ID, and the cover sheet documents methodology and entity metadata. We’ve designed the template alongside Big-4-trained sustainability auditors.
How is this different from Persefoni or Watershed? +
Persefoni and Watershed are enterprise carbon ledgers built for organisations with dedicated sustainability teams, priced at five-figures-and-up annual contracts. Auditably is built for the mid-market CFO who needs an IFRS S2 disclosure now, doesn’t have a Climate Controller, and wants to keep the work in Excel where their auditor already lives.
Do I need an OpenAI or Claude API key? +
Only if you want Auto-API Mode (Pro plan), which automates the entire pipeline. The Practitioner plan works with the free ChatGPT or Claude.ai web interfaces — you just copy our prompts in and paste responses back. Both paths produce the same audit-ready Excel output.
Where is my data stored? +
Nowhere we control. The entire tool runs in your browser. CSV uploads, configuration, and AI responses live only in your tab — they’re not sent to Auditably servers. If you use Auto-API Mode, your data goes from your browser directly to OpenAI or Anthropic over HTTPS, with your own API key.
What if my auditor rejects the format? +
We’ve never had that happen, but if it does, send us the auditor’s feedback at support@auditably.co and we’ll update the template at no charge. Our 30-day money-back guarantee covers you regardless.
Does this work for my industry? +
Yes — IFRS S2 plus the SASB industry-based guidance covers all 77 SASB industries. The Master Disclosure Prompt asks you for your SASB industry code in Step 2, and the AI tailors the narrative accordingly. We’ve tested it across manufacturing, real estate, financial services, logistics, and resources.
Which jurisdictions does this support? +
IFRS S2 is being adopted in 30+ jurisdictions including the UK, Australia, Singapore, Malaysia, Canada, Brazil, Nigeria, and Hong Kong. The output also aligns with California SB 261, EU CSRD/ESRS E1, and TCFD legacy disclosures, so the same workbook serves multiple filings.
Can I export to Workiva or another reporting platform? +
The Excel output is RFC-4180 compliant and can be imported into Workiva, OneStream, or any system that accepts .xlsx. Many customers use Auditably to generate the first draft, then move it into Workiva for XBRL tagging and final filing.
Is this GDPR-compliant? +
Because we don’t process or store your data, GDPR Article 28 (data processor) obligations don’t apply to us. Your data stays in your browser. If you use Auto-API Mode, OpenAI’s and Anthropic’s standard data-processing terms apply between you and them.
What’s included in Pro that Practitioner doesn’t have? +
Pro adds Auto-API Mode (no manual copy-paste — the AI runs the entire pipeline), multi-entity support (up to 5 subsidiaries with separate workbooks), FY-over-FY comparison, auditor share links, and a real-time IFRS S2 paragraph coverage tracker.
How long does it take to produce a full disclosure? +
On the Practitioner plan with manual copy-paste: 15–30 minutes for a clean dataset. On the Pro plan with Auto-API: 2–4 minutes end-to-end. Compare to 4–12 weeks for a typical consulting engagement.
Can I try before I buy? +
Yes. The 30-day money-back guarantee on monthly plans gives you a full reporting cycle to evaluate. If Auditably doesn’t produce a workbook your auditor accepts, email us within 30 days for a full refund — no questions asked.
