Which drawing is current?
It is easy to work from an older drawing. PinArch keeps the published version and its history together.
Pilot program: early access open
Your client knows what they approve. You know which design to move forward with.
Share designs, revisions and material decisions by project. See exactly which version each decision belongs to.

One project. A clear next step for both sides.
No real client data. Explore two versions and the office/client perspectives. Choices are not saved and do not create approvals.

Client view
What do I need to do?
Review the current design, see what changed and ask questions alongside the relevant image.
Material preferenceExample preference: light oak. Saving a preference is separate from approval.
Approval for a specific versionIn a real project, approval requires consent for the stated version and a fresh code sent by email.
Apply to pilot your own projectHow it works
Three steps to a shared decision
Prepare a draft, explicitly publish it, then track feedback and decisions.
- 1
Prepare the draft
Set up rooms and phases; add images, PDFs and material cards. Uploading does not automatically share content with clients.
- 2
Publish for your client
Publish the version you want to share and send the invitation. Clients access the project with a free account.
- 3
Track the decision
See comments and revisions in context. Material preferences are separate from approval; approving a specific version requires a fresh email code.
Who it's for
Easy for both sides
For studios
- All projects, phases and pending approvals on one dashboard
- Client view with your logo and colour
- Team assignment and a quick start with project templates
- Reuse your material library across projects
For clients
- One account for projects from different studios
- Comfortable on a phone, with pinch to zoom
- Pending approvals, a phase bar and recent activity show where the project stands
- Interface in their own language
Features
Your whole client process in one place
From revisions and material choices to chat and approval.
Pinpoint comments
Pins are placed exactly where they matter on an image or PDF. Each pin is its own thread.
Version history
Every revision is archived as V1, V2, V3. Older versions and their comments are never lost.
Material board
Flooring, paint (RAL, NCS and more), tiles and furniture cards. Offer alternatives and let your client choose.
Recorded approvals
Approvals are tied to a specific version. Email code verification, server time and a file fingerprint are recorded with each one.
Explore all features
Project chat
A project chat for conversations that don't fit a pin. Messages can be linked to the related item.
Four languages
Your client sees everything in their own language: Turkish, English, German and Arabic.
Approval report
Collect approved items, chosen materials and revision history in a single PDF report.
Meeting scheduling
Schedule meetings with a Meet, Zoom or Teams link; your client gets a calendar invite and decisions are noted.
Project phases
Split the project into phases such as survey, concept and construction; link items to a phase.
First form for clients
Collect requirements at the start: short and long text, choice, date and image questions.
Project templates
Set up phases, rooms, first-form questions and approval points from a template in one step.
Notifications and reminders
Stay informed in the app and by email about new versions, comments, revisions and approvals.

Security
Your projects stay private
Only authorised office team members and invited clients/viewers. Viewers cannot approve.
Who can see the project?
Only authorised office team members and invited clients/viewers. Viewers cannot approve.
Does a new version change an earlier approval?
No. The earlier approval stays in history. Each newly published version is reviewed separately; drafts stay hidden from clients.
What does approval record?
Person, time, version and content hash are stored as an evidentiary record. This is not an electronic signature or a guarantee of legal validity.

PinArch is being built to simplify the most draining part of an architecture studio's client work.
Why PinArch?
An interior project involves dozens of renders, hundreds of material decisions and countless revisions. Most of those decisions are still made in messaging apps, voice notes and phone calls.
The result: lost notes, repeated questions and “that's not what I asked for” debates once work begins on site.
PinArch brings this process into one transparent space: the client views, comments and approves; the studio keeps a record of every decision.
Simplicity
No account, no setup and no learning curve for your client.
Transparency
Every decision shows who made it and for which version.
Privacy
Your projects are yours; files are never published publicly.
FAQ
Frequently asked questions
Does my client need an account?
Yes, and it is free. Your client creates an account with their email and a password from the invitation link; the same account shows projects from different studios. When approving, a fresh code sent to their email is also required.
Is an approval legally binding?
PinArch records each approval with the approver's verified email, server time, version and file fingerprint. This is not an electronic signature; please consult your lawyer for a legal assessment.
Which file types can I upload?
JPG, PNG, WEBP and HEIC images and PDF drawings. External links such as Kuula or Matterport can be added for 360° tours.
How much does it cost?
During the pilot, plans are assigned by our team and there is no charge. Pricing will be announced after the pilot.
Is there a mobile app?
PinArch runs in the browser and can be added to your phone's home screen like an app. Nothing else to install.
Can a client withdraw an approval?
The client sends a withdrawal request with a reason; only if the architect accepts does the item await approval again. The original approval record is never deleted; the request and the decision are kept as separate records.
