Frequently asked questions about Santix

Santix is a construction site and project management app where the site manager, field engineer, architect and subcontractors look at the same drawing and work from the same numbers. It runs on iPhone and iPad and keeps recording when there is no connection.

iPhone and iPad. The Android version is in preparation. The web panel is only for organisation sign-up, seats and invoices; field work happens in the app.

It will be on the App Store soon. For now we offer early access through TestFlight; apply through the contact form.

The app interface is in Turkish. Its terms follow Turkish site practice: pafta (drawing sheet), mahal künyesi (room data sheet), hakediş (progress payment), revize, taşeron. See the construction glossary.

On site: drawing markup with pins, room data sheets, revision tracking, progress tracking and offline work. In the office: schedule, progress payments and budget, bid comparison, contract templates and document tracking. All on the features page.

It imports MS Project XML and Primavera P6 XER schedules and Excel or CSV cost estimates and room schedules, and exports the budget and payments to Excel. There is no BIM/IFC support, no accounting software link and no e-signature.

Timesheets, personnel entry and exit, stock and stores, plant tracking, statutory accounting, e-invoicing and e-signature are not in Santix. It does not replace the official electronic site diary either.

Yes. Pins, photos, voice notes and status changes entered offline stay on the device and sync when the connection returns. Download drawings in advance with "Tümünü indir" (download all) in the offline section of the drawings screen. More on the offline field app page.

On sync the changed fields are sent and the last value written wins for each field; status history is kept. A change that breaks permissions or the revision flow rules is refused and listed for you with the reason.

Uploading drawings, AI suggestions and actions that need a server decision, such as redeeming an invite code, need a connection. The app says so on those screens.

Title, description, type, category, priority, assignee and due date; photos (camera or gallery), voice notes and video. Comments and status history are kept under the pin.

Six types: task, defect, request for information, observation, safety and revision request. Statuses are draft, open, in progress, blocked, awaiting inspection, done and closed.

You draw the finished area on the drawing or mark a whole room as done. Santix computes the percentage from the work item's measurement basis: floor area, wall area, ceiling area, perimeter or count. See progress tracking.

Yes. Progress on work items in rooms rolls up into linked tasks, and tasks into the Gantt. "Sahadan hesapla" (calculate from site) in the schedule updates task progress from site records.

DWG, DXF and PDF. Santix splits the file into sheets and reads each sheet's number, title and scale from the title block.

Yes. Many Turkish offices draw sheets side by side in model space instead of layouts; Santix finds the sheets from the title block and frame.

In our November 2026 tests, a 7-storey working drawing set became 11 sheets and 267 room suggestions in about 11 minutes. A 58-sheet structural set was split into 58 sheets in about 28 minutes.

No. Drawings are processed on Santix's own CAD server on Google Cloud Run in the Frankfurt region (europe-west3); the Autodesk cloud is not used.

Pins move to the new version and keep their position in drawing units. You can overlay two versions with adjustable opacity; see revision tracking.

Santix reads room tags and wall lines and suggests rooms and areas. Suggestions go through the layers, rooms, finishes and approval steps of the room review screen and are not written to a room data sheet until approved.

No. Structural sheets such as formwork, reinforcement and column setting-out are split, but no rooms are suggested; the 58-sheet structural test set correctly produced none.

If the title block says mm but the drawing is in cm, Santix notices by comparing areas with those written on room tags. This was caught that way on a real project.

Cumulatively: previous payments are subtracted from the total value of work to date, then retention, advance recovery, penalty, withholding tax, stamp duty and VAT withholding are applied. An example from ₺100,000 to ₺89,552 payable is in the progress payment guide.

The site manager. If its lira value exceeds the organisation threshold, ₺500,000 by default, the owner approves after the site manager. The approval history is kept on the payment.

TL, USD and EUR. Foreign currency lines are converted at the Central Bank rate of the relevant day; rates are fetched daily and each payment keeps its rate date.

By item and by subcontractor. Each line shows planned, committed (signed contracts), actual (approved payments), remaining and an overrun forecast.

No. Santix holds the payment calculation, approvals and paid status; bank payments, statutory accounting and e-invoicing stay in your accounting software.

Subcontract templates for 40 trades, from excavation and concrete frame to plumbing, lifts, scaffolding and ready-mix concrete. Your organisation can add its own templates. See contract templates.

No. The templates are drafts awaiting legal review; have them checked by your lawyer before signing. There is no e-signature in Santix; the signed PDF is attached to the contract.

Default weights are price 60 %, duration 10 %, payment terms 10 %, material quality 15 % and references 5 %. You can change the weights per project; the chosen bid is posted to the budget and linked to a contract.

No. Requests go out by your usual channels; incoming bids are entered in Santix, or their items are taken from Excel.

Time-limited papers such as the building permit, building inspection contract, health and safety certificates, all-risk policy, guarantee letters and crane, scaffold and electrical inspection reports. The list is in the site document checklist.

By default you are notified 30, 14, 7 and 1 day before expiry; the reminder days can be changed per document.

Scan it with the camera or pick a PDF or image of up to 50 MB. Document type, number and dates are read from the page; you check them and save.

Classifying drawing layers, matching a room schedule to rooms and suggesting finishes, mapping Excel columns, reading documents, invoices and delivery notes from a photo, filling contract questions and drafting clauses, and summarising bid comparisons. See AI assistance.

No. Every suggestion is recorded only after you approve it. If a suggestion is unavailable you can do the work by hand; the app works without AI.

Not yet. In bid comparison, prices come from the bids firms send you.

Requests go to OpenAI through Santix's server, with storage turned off (store=false) and without your user id. Summaries such as layer names are sent, not drawing geometry.

Owner, organisation admin, project manager, site manager, field engineer, architect, subcontractor and viewer. Each person sees only what their role allows; the full table is on roles and permissions.

Only work assigned to them or opened by them, and their own firm's contract and documents. They can read the drawings; the budget, bids, payment amounts and other subcontractors' work stay hidden.

By default the owner, project manager and site manager. The owner or organisation admin can open the budget per role or per person at none, summary or full.

The site manager or the owner. An approved request goes to the architect, who answers with a note or a new drawing version, and the site manager closes it.

On the project's team screen choose a role and create an 8-character invite code. It is valid for 14 days, single-use, and shared by WhatsApp, SMS or email.

Yes. Every active user, including architects and subcontractors, uses a seat. Their roles are project-scoped, so they do not see your firm's other projects or settings.

Monthly prices including VAT: 5 users ₺4,999, 10 users ₺8,999, 25 users ₺19,999, 50 users ₺34,999. That is roughly ₺1,000 down to ₺700 per person. Details on the pricing page.

Every new organisation gets a 3-day free trial. If no plan is chosen at the end, the account becomes read-only and no data is deleted.

The organisation owner subscribes in the app under Ayarlar › Plan ve ödeme (Settings › Plan and payment). The subscription renews automatically; cancel in App Store settings at least 24 hours before the period ends.

Nobody new can join; they see that the organisation's licence quota is full. Existing users keep working; you upgrade the plan or remove someone who has left.

For annual plans, more than 50 users, or bank transfer with e-invoice, write to satis@santix.app.

Data is stored with Supabase in Frankfurt (EU), and drawings are processed on Google Cloud Run in Frankfurt. More on the security and KVKK page.

In the database. A record a person may not see is never sent from the server, so it is not on their phone either. Changes to critical tables are written to an audit log.

No. Santix does not collect location, and the app has no ads, tracking or analytics SDK.

In the app go to Ayarlar › Hesabımı sil (Settings › Delete my account). Records you created in the organisation's projects, such as pins and approvals, stay with the organisation.

Yes. Santix imports MS Project XML and Primavera P6 XER files and computes the critical path itself. Save MPP files as XML first.

Yes. An AI suggestion maps the item code, description, unit, quantity, unit price and total columns to budget fields, and you confirm it.

Yes. Upload the current drawings, import the estimate and programme, and turn open snags into pins on one site walk. Closed work and past payments do not need to move.

For one small job run by one or two people, Excel and WhatsApp may be enough. With several subcontractors, regular revisions and monthly payments the difference shows; see Santix instead of Excel and WhatsApp.
