Q: How do you handle F-Gas and ErP regulatory revisions?

Each document version is versioned. When you upload the 2026 ErP revision answers index the new text automatically; the previous one becomes archive. Audit log shows which version generated which answer.

Q: Does it work with manuals in multiple languages?

Yes. Documents can be uploaded in any of the 8 supported languages and answers are served in the customer’s detected language regardless of source.

Q: Can I restrict answers to certified installers only?

Yes. SSO groups can gate parts of the knowledge base; technical service bulletins remain installer-only while end-customer manuals stay public.

Q: Integrates with service CRMs (e.g. Salesforce Service Cloud)?

Yes — bi-directional webhook to Salesforce, ServiceNow or any HTTP endpoint, with the full conversation transcript and citations.

Technicians find the right manual, the right schematic and the right past case in seconds. Voice-first for hands-busy work, multi-language by default.

Three problems specific to this sector

Opaque error codes

E03, F112, A4-warning. Keyword search alone fails; semantic search loses the code. helpcode uses hybrid retrieval with BM25 boost on alphanumeric codes.

Installers on the move

Answers from a phone, on scaffolding, in 8 languages. AI hotline with voice recognition + synthesised reply. End-to-end latency < 1.4s.

Compliance + certifications

CE, ErP, F-Gas, EN 14511. Every answer cites the right regulation. Regulatory updates tracked in an internal changelog.

Typical workflow

01 Upload. PDF manuals + tech sheets + service bulletins. Chunking specialised for text + tables + error codes.

02 Tuning. Internal reviewer validates 50-100 typical questions. We tune hybrid retrieval and reranker on the first-run false positives.

03 Deploy. Chat widget on the installer portal + AI green-number for voice. SSO to your CRM, CSV log export.

04 Iterate. Dashboard surfaces unanswered questions. Add a manual → indexed in 4-8 minutes → live.
