AI-ASSISTED · EVIDENCE-BACKED · VERIFICATION READY
Catch issues before they cost you time, money and credits.
CarbonFlow Preflight helps you prepare your carbon project documents, data and calculations for independent verification — faster, cleaner and with full traceability.
60%Faster verification preparation
40%Lower consultant effort
90%Issues caught early
100%Evidence traceability
Hash-verified evidenceEvery uploaded document is fingerprinted and never overwritten.
Traceable to the sourceEach value points to a page and passage you can open.
Rules, not guessesDeterministic checks decide. AI only reads and explains.
Reproducible runsRulepack, engine and inputs are frozen with every run.
From raw files to a reviewable record.
Five stages, each leaving a trail you can inspect later.
Upload
Add monitoring reports, meter logs and agreements for a monitoring period. Files are stored privately and hashed.
Extract
Key values are read from each document and kept with their page and passage. Anything uncertain goes to a person.
Validate
Versioned rules check completeness, units, dates, calculations and consistency across documents.
Review
Your team works through findings, corrects inputs and records a reason for every decision.
Report
Export a preflight report and an evidence manifest that a verifier can follow back to the source.
Every finding shows its evidence.
No black box. Open any result and see the rule, the input and the passage behind it.
Evidence beside every value
Read the extracted figure next to the exact passage it came from, then accept or correct it.

Versioned rule checks
Completeness, units, dates, calculations and cross-document consistency.
Reviewable decisions
Acknowledge, resolve or dismiss a finding with a recorded reason. History stays.
Report and evidence manifest
A readable report plus a manifest of document hashes and source locations.

Frozen inputs per run
Re-run after corrections without losing the original. Compare runs side by side.
A preparedness tool, not a verifier.
Independent verifiers make the verification decision. Preflight helps you arrive with fewer surprises.
What it does
- Checks data and calculations against versioned rules
- Links each finding to its source document and passage
- Keeps a history of reviews and corrections
- Produces a report and an evidence manifest
What it does not do
- Certify or verify a project
- Predict whether credits will be issued
- Replace an accredited verifier
- Let an AI model decide compliance
Run your first preflight.
Create a project, add a monitoring period and bring your evidence.
