AI-assisted report writing: Tracelia drafts the text. You choose every word.
In Tracelia, the AI drafts from your findings: analysis, conclusions, recommendations, cost estimate. You review, correct or rewrite each draft, by keyboard or by dictation, then you approve it. The report assembles only what you approved, and you sign it alone.
Tracelia is available in French today. Join the list to hear when the English version opens.
“At zero slope, the ponding near that drain is not a defect in itself; the flashing is: NF DTU 43.1 requires at least 0.15 m above the ballast.”
« À pente nulle, la flache relevée près de cette entrée n’est pas en soi un défaut ; le relevé, si : le NF DTU 43.1 exige au moins 0,15 m au-dessus de la protection. »
On one demo case: what the AI puts in front of you, and what you do with it. Interface shown in French.
What it reads
It starts from what you saw.
The draft is prepared from your findings: a location, your observation typed or dictated on site.
If it states a fact you didn’t observe, you take it out before you approve.
Tracelia was designed for French practice: analyses refer to French codes of practice (NF DTU) where relevant.
What it writes
What’s established. What’s still to check.
On a leak at the edge of a flat roof: the measurements taken, the standard cited with its value, the probable cause, then what still needs checking.
Uncertainty isn’t erased. It’s written down.
Analyse du constatBase flashing too low, parapet leak
establishedMoisture-meter readings within the 80 × 45 cm ceiling stain are three times those of a sound area nearby.
establishedDirectly above, the base flashing has pulled away from the parapet over 1.20 m and stands only 8 cm above the gravel ballast. Measured slope: 0.5%; a single roof drain, no overflow.
probable causeAt zero slope, the ponding near that drain is not a defect in itself; the flashing is: NF DTU 43.1, France’s code of practice for waterproofing low-slope roofs, requires at least 0.15 m above the ballast. With no overflow, water from a heavy rain can reach the detached section: that is the probable cause.
to be verifiedA localized water test must confirm this path and rule out the drain flange.
limitI cannot establish how long the flashing has been detached, or whether it already was at handover.

More excerpts, in the sample reportOne draft per step. Never the report.
Each step gets its draft; the report assembles only what you approved.
| Case step | What the AI drafts | What the expert does |
|---|---|---|
| Finding analysis | A draft linking the observation to a probable cause; it can be regenerated | Reviews, edits, then approves: “Analyse validée” (analysis approved) |
| Conclusions | A summary of the approved findings | Edits the draft, then accepts it |
| Recommendations | Prioritized measures: protective measures, further investigations, repairs, maintenance | Edits the draft, then accepts it |
| Cost estimate | Lines by trade, each showing its origin (rule, AI, manual entry) | Adjusts prices and quantities, then accepts |
| Report | Nothing: the report assembles what you approved | Generates the report, reviews it and signs it |
Approval stays in your hands.
Until you approve an analysis, the finding stays pending review. The report can be generated only once the required steps are approved.

6 in 10
In production, the expert approves 6 out of 10 AI-drafted texts unedited, after reading them. The expert edits the other 4 before approving: that’s what the review is for.

Refine
Say what’s wrong. No retyping.
A passage isn’t right? Dictate an instruction (in French, like the interface; translated here): “be more cautious about the origin of the crack,” “drop the reference to NF DTU 20.1 and rephrase.” Tracelia proposes a new version and flags every block it changed.
You compare block by block, keep or reject each change, then approve. The original draft stays as it is until you decide.
ConclusionsFictional case

III. Sign-off
Tracelia changes nothing on its own. It shows you where to look.
Before you edit an approved analysis, Tracelia lists the sections that depend on it: conclusions, recommendations, cost estimate, report.
The analysis goes back to pending review. Each affected section comes back to you for a fresh approval.

AI in TraceliaTracelia uses a generative AI model to draft an analysis from your site findings. AI can make mistakes: you review, edit and approve every report, and you sign it as the responsible expert.
Questions
Your questions.
Can Tracelia’s AI make mistakes?
Yes. It can suggest an unlikely cause, an inaccurate wording or a claim your findings don’t support. That’s why no draft reaches the report without your review and approval.
How does a fact you didn’t observe stay out of the report?
The draft is prepared from your findings. If it states a fact you didn’t observe, you take it out before approving: no draft reaches the report without your approval.
Who is the author of the report?
You are. The AI drafts; you correct, approve and sign the report as the responsible expert. The report carries your firm’s identity and format.
Does the AI price the work for you?
It proposes lines; you settle the estimate. Each line shows its origin: rule, AI or your own entry. You adjust prices and quantities, then accept the estimate.
Expert cost estimate, given as a range; not a contractor quote.
Are my cases used to train AI models?
No. The terms rule it out: they grant no right to train models on your cases. Your cases are not used as training data without your separate, specific and freely given consent.
Does the AI work in English?
Not today. Tracelia, its interface, its drafts and its reports are in French, and analyses follow French practice.
Does the AI cite standards?
Yes, where they apply: NF DTU, Eurocodes, NF standards, and French statutes (Civil Code, Construction and Housing Code, Insurance Code). It looks them up on the web while drafting and names them in the text of the draft, without a list of links. A cited reference can be inaccurate or out of date: you check it against the current edition before you approve.
