Without signing in, you can build one presentation per browser, and it costs no credits — neither now nor after you move it. You can publish it only once it's saved to your dashboard.
Open the save form
When the slides are ready, a “Save the presentation” block with a sign-in form appears above them. If you've scrolled down, the “Save” button at the bottom of the screen takes you back to it.
Sign in
Enter your email and press “Email me a sign-in link” — no password needed. Or press “Continue with Google”. If you don't have an account yet, signing in for the first time creates one.
Open the link in the same browser
Open the link from the email in the browser where you built the presentation: only that browser knows it's yours. If your mail app opened the link in a different browser, sign in again in the right one — the move starts there.
Confirm the move
JamPres shows the email you're signed in with and asks “Move the presentation to this account?”. Press “Move it” and the presentation page opens. From there you can edit it, publish it and share the link.
A draft made without signing in is kept for 7 days. If you already have a presentation on Free, the draft waits: upgrade or delete the earlier one, and it will move over. You can't build a second presentation in the same browser without signing in — JamPres will ask you to sign in, and the first one moves to your dashboard too.
