Talking to Hemma — what to ask

Hemma has a built-in AI chat that knows your project. Ask a question in plain language and it looks at your invoices, quotes, contractors, budget and the phases of your build, and searches your emails and notes (with links to the source so you can verify it yourself).

01What Hemma knows

Hemma answers questions based on what is in your project:

  • Money and contractors: what is outstanding, what is overdue, and what has been paid, per contractor and for the whole project
  • Budget: the roll-up per budget line (estimated, budgeted, quoted, invoiced)
  • Emails and notes: Hemma searches the subjects and the full text of your emails, and the text of your own notes
  • Findable by name: documents, contractors, budget lines and events are found by their name
  • The phases of your build: which phase you are in, what follows, the milestones and decisions each phase holds, what each of them means, and when a decision has to be settled. This plan is there from the day your project is created, so these questions work before you have uploaded anything

One boundary worth knowing: Hemma does not read the text inside a file you uploaded. It knows a document's name, its type, and the fields that were extracted from it (amounts, dates, VAT number). It cannot quote a clause from a contract or a line from a specification.

Hemma does not know things outside your project. It cannot look up public records, access the internet, or answer general construction questions. It does answer questions about the phases of your build — but from your own plan, not from general construction knowledge.

02Questions that work well

  • "What's still outstanding with my contractors?"
  • "Which invoices are overdue?"
  • "How much have I paid the electrician so far?"
  • "How much of my budget is invoiced already?"
  • "Which quotes do I have for the roof?"
  • "How much has been invoiced compared to what was quoted?"
  • "What did the roofer write about the delivery time?"
  • "We just bought the plot, what should I do first?"
  • "Which phase am I in, and what comes after it?"
  • "What does 'Choose construction system' mean, and when does it have to be decided?"

03What Hemma won't do

Hemma is a read-only assistant. It answers questions, it does not take actions on your behalf. It will not pay an invoice, send an email, or update your budget. It also does not make predictions or estimates beyond what is in your project data.

If Hemma does not find an answer, it says so clearly rather than guessing, and points you at the screen where the answer does live, with a link when it already found something.

If there is nothing in your project yet, Hemma says that too. It won't promise you numbers it does not have, and the example questions stay away until your first document is in.

04Where to find it

The Hemma chat is in the main navigation. Look for the chat icon or "Talk to Hemma" link.

05Usage limits

You can ask up to 20 questions per hour. This limit resets every hour. If you hit it, wait a few minutes and try again.

06Common questions

Does Hemma learn from my questions? Hemma uses your questions only to answer them. Questions are logged in a privacy-safe way (names and amounts are stripped) to help improve the product, but they are not used to train AI models on your data.

Can I ask in Dutch or French? Yes. Ask in whatever language you like: Hemma always answers in the language set on your profile.

Hemma gave me a wrong answer. The AI has access only to what is in your project. If a document was not processed correctly, the answer may reflect that error. Follow the source link in the response to check the underlying data. If something is wrong with a document, see reviewing and correcting what the AI extracted.
