Frequently Asked Questions

Could a company's sustainability team use ai-data-extractor for emissions data?

No. It reads AI coding-assistant chat history from local app data directories and emits JSONL conversations. It has no emissions factors, no disclosure templates, and no reporting outputs.

Is ai-data-extractor really free with no catch?

It is MIT-licensed and runs entirely locally with no account and no upload. The trade-off is support: there is no hosted service or SLA, and Windsurf and Trae parsing is heuristic against undocumented schemas, so those can break when those apps change.

Who is explicitly not a Persefoni customer?

Small businesses wanting a cheap simple calculator, non-regulated organizations with a single-scope footprint and no assurance requirement, teams wanting open-source or self-hosted accounting, self-serve buyers, and companies unwilling to invest internal time in data quality.

Does Persefoni's AI certification matter to a buyer?

It obtained ISO/IEC 42001 certification for its AI management system in August 2026, which is relevant if your procurement or assurance process requires documented AI governance. It says nothing about extraction tooling.

Which assistant sources does ai-data-extractor cover today?

Claude Code, Codex CLI, Cursor, Windsurf, Trae, Continue, Gemini CLI, OpenCode, Cline, Roo Code, and Aider — the last two added in the January 2026 releases.

Can I run Persefoni without a sales conversation?

The product's own not-for list includes buyers who need to self-serve the full disclosure suite, so expect a sales-led onboarding rather than instant checkout.
