SahaSesi AIA YazSis brandSahaSesi AI is an AI-assisted construction site logging product built for contractors. Foremen and crew leads send text, voice messages and photos to a single WhatsApp number; the AI sorts each message into work log, timesheet, material request, defect and incident records (including occupational health and safety, OHS). The office checks and approves in the panel, and managers receive the site report as a PDF every evening.
Pilot programLaunching through a pilot program with the first construction sites.

Your team doesn’t need to learn a new program; the WhatsApp they use every day is enough. The only thing that changes is that messages now turn into records.
Open the site; enter the name and mobile number of the foreman and subcontractor leads. Each of them gets a short welcome message on WhatsApp.
A photo, a voice message or a short note. The message is sorted by type and answered with “Logged”; if it was misunderstood, the foreman corrects it.
Records line up in the panel by type; those that can’t be confirmed land in the “awaiting review” list. Once the site chief approves, the daily report is locked.
Every evening a single PDF with a section per site goes to managers by WhatsApp and email; the monthly timesheet downloads to Excel.
Messages are sorted into five record types; the lists and reports the office needs come out of them automatically.
“Column formwork on the 3rd floor of Block B is finished” is added to the daily report with block and floor details.
“Kaba crew 12 people, rebar fixers 4 people half day” is logged per person or per subcontractor crew; half days and overtime are tracked separately.
“We need 20 m³ of concrete tomorrow” becomes a request; when the delivery note photo arrives, a delivery record is opened.
A defect with a photo is opened against the responsible subcontractor and closes when the closing photo arrives.
Work accidents, work stoppages and inspection visits are logged separately; an OHS incident appears in red at the top of the evening report.
Records can be corrected, approved and exported; every change leaves a trace.
Voice messages are converted to text and photos are attached to the record; consecutive messages from the same person are processed together.
Each record is read back to the foreman as “Logged: …”; when they write “no, it was 10 people”, the record is corrected.
A message that can’t be confirmed or processed lands in front of the office; no record is silently lost.
The day’s records line up in the daily report automatically; once the site chief approves, the report is locked and only a manager can make later changes.
One page per site; it reaches managers by WhatsApp and email every evening, and past reports stay in the panel.
The monthly timesheet downloads to Excel by person and subcontractor, day by day, with half days and overtime.
If a site’s timesheet hasn’t arrived by the reminder time, its foreman gets a reminder on WhatsApp.
The daily report and PDF are prepared with the site’s weather for that day.
The screens are taken from the product’s live demo; records are color-coded by type.

SahaSesi AI is a construction site logging product that uses AI to turn the text, voice messages and photos that foremen and crews send on WhatsApp into work log, timesheet, material, defect and incident records, giving the office a panel and managers a PDF report every evening. It is a YazSis brand.
No. The WhatsApp they already use is enough. You add the person’s name and phone number in the panel, they receive a short welcome message, and after that they just write to that number.
No, the bot cannot read messages in WhatsApp groups; the infrastructure WhatsApp offers businesses does not allow it. Send the message to the bot directly, or forward the group message to the bot with “Forward”.
WhatsApp holds the message on the phone and sends it itself when the signal returns. The record is written to the day the message arrives; if the message contains an explicit reference such as “yesterday”, it is processed up to three days back at most.
Records, photos and audio files are kept in a data center in Frankfurt (Germany, EU). Messages come in through WhatsApp (Meta); the AI and speech-to-text services are in the US. These transfers are made under Article 9 of KVKK (Turkish data protection law).
It can happen, which is why each record is read back to the foreman as “Logged: …” and the foreman can correct it. Records that can’t be confirmed land in the office’s “awaiting review” list; the daily report is locked after the site chief’s approval.
