FAQ

Questions.

Which reports can it read?

Lab PDFs, Word files, Excel/CSV sheets and photos of the results sheet. If a value can't be read, you type it in.

Is my report kept private?

The file is read in your browser and not stored. Only the readings are sent to our AI provider (Anthropic) to write the recommendations; they are deleted within 30 days and not used for training.

Does it replace an engineer?

No. It gathers the evidence and suggests next steps; a qualified engineer reviews and signs the report.
