Two free clinics before custom GPTs retire.

Last updated · By Chris Tabb, founder · Sources checked November 13, 2026

Appearly is hosting two free 45-minute online clinics on Tuesday, December 1, 2026, 12:00–12:45 PM ET and Tuesday, December 8, 2026, 12:00–12:45 PM ET. We’ll walk through migrating a custom GPT — OpenAI’s path is My GPTs → Migrate to plugin — and answer questions before the standard retirement date of December 11, 2026. The joining link will be emailed to you before the session. Appearly is not affiliated with OpenAI.

§ 01

What we’ll cover

  • How to inventory the custom GPTs you still rely on, and which ones to retire.
  • OpenAI’s official path: My GPTs → Migrate to plugin, and when a Project is a better fit.
  • What transfers (instructions, knowledge files, connected apps) and what doesn’t (custom actions, the selected model, sharing settings).
  • The step most teams miss: the new plugin starts private, so you have to reshare it and replace any public GPT links.

Our honest take

Bring one GPT you’d like to keep. If you can’t, watch the walkthrough and ask about yours.

§ 02

How to join

Sign up with your name, work email, company, and a preferred date (or “either”). We’ll send a confirmation from hello@appearly.app, and we’ll email the joining link before the session. There is no meeting link on this page yet.

Add a session to your calendar: December 1 or December 8. Both run 12:00–12:45 PM Eastern Time.

§ 03

If you’d rather have it done

Custom GPT migration starting at $2,500, billed as a fixed fee after a short review of how many GPTs you have and whether they use custom actions. OpenAI seat costs are separate. Use the migration triage form if you want a quote, or come to the clinic first.

§ Reserve a seat

Sign up for a clinic

Both sessions are free, 45 minutes, and online. We’ll email the joining link before the session — it isn’t published yet, so don’t look for a meeting URL on this page. Appearly is not affiliated with OpenAI.
