You marked up a plan. Now you want your architect to see it, answer your questions, and add their own remarks. You don't want to send them a Hemma account, you don't want to give them access to your invoices, and you don't want to start a new email thread with screenshots. Sharing solves all three. One plan, one link, full collaboration.
When you share a plan, Hemma generates a secure link tied to your architect's email address. They open it, confirm their email, and get a view of that one plan: your annotations, the document itself, and a place to reply.
That is everything they get. No access to your other plans. No view of your budget. No window into your contractors or invoices. The share is scoped to a single plan, and the rest of your project stays private.
Open the plan you want to share, then look for the share option in the plan view. Enter your architect's email address, and Hemma sends them an invitation. The link expires after a period you choose. You can revoke it at any time.

Use the email address your architect already gives out professionally. Hemma uses it to verify them on every visit, so a stable address keeps things friction-free.
Your architect receives an email with a link. When they click it, Hemma asks them to confirm the email address. A quick safety step that means no one else can use the link if it gets forwarded. Then they enter their name, agree to terms, and the plan opens.
What they see:
What they don't see:

Architects work with a deliberately smaller toolkit. They can:
They cannot draw circles, arrows, rectangles, or freehand shapes. Those tools belong to you. The thinking is simple: your architect's job is to advise, not to redline. Pins and replies cover almost every conversation that needs to happen.
Every reply, from either side, triggers an email to the other people on the annotation thread. Your architect replies and you get a notification. You reply and they get one. Nobody has to log in just to check whether anything changed.
Inside Hemma, new replies show up with an unread indicator on the annotation card. You can scan the sidebar at a glance and see exactly where the conversation has moved.
If the project is finished, the share is no longer needed, or you simply changed your mind, you can revoke the link from the same place you created it. Revoke is immediate. The next time your architect tries to open the plan, they see a notice that access is no longer available.
The annotations and replies they added stay on the plan. Revoking access does not delete the conversation. It only stops new visits.
The old way: forward a PDF, attach a screenshot, write a paragraph explaining what to look at, hope the reply lands in the same thread, lose track when the next plan revision arrives. The new way: one link, one document, one conversation that stays attached to the drawing.
Your plan stays the source of truth. Your architect joins the conversation. The thread stays in one place.
