Rethinking Inc.
Free · No student accounts · Edit anytime

Your custom GPT just got canceled. Build its replacement in three minutes.

ChatGPT is retiring custom GPTs. Google is retiring Gems. The thing teachers actually used them for, a bot you design and students open from a link, lives here now.

Write the instructions. Share the link. Students chat with no accounts and no setup. Build up to ten bots and edit them all semester.

1

Write the instructions in plain language, the same way you built a GPT or a Gem. Who the bot is, what it does, what it never does.

2

Copy the student link. Put it in your LMS, your slides, or an email. Students open it and chat. No accounts, no logins, no app.

3

Edit anytime. The link never changes, so you can sharpen the instructions mid-semester without re-sharing anything.

Who this is for

The GPT refugee

You built a custom GPT or a Gem your students actually used, and a platform decision is about to delete it. Your instructions paste straight in here.

The role-play designer

Practice patients, mock customers, debate opponents, historical figures. You want students talking to a character you control, without managing thirty accounts.

The first-timer

You have never built anything like this. The instructions are plain English, the first bot takes about three minutes, and there is a live demo below to steal from.

Your builder

Try the student side first

This is a live bot I built in about four minutes: a practice customer my entrepreneurship students interview. You get the same link a student would, no account, no setup. Try pitching him a product and watch what happens.

The fine print, in plain language

  • Free, with caps that keep it free: 25 messages per student session and daily limits per bot. A typical class session stays well inside them, and a refresh starts a fresh session.
  • Students stay anonymous. The bot is instructed never to ask for names, grades, or anything identifying, and there are no student accounts to create.
  • Your instructions stay private. Students chat with the bot; they never see the prompt behind it.
  • You own the data, and there is almost none. You own your bot and can edit or delete it anytime. Conversations are not stored, and when the tab closes, the chat is gone, with one exception: a student can choose to share a chat with you, which saves that one conversation and gives them a link to hand you.
  • Built by a teacher. I publish a practical AI workflow for teachers every week at How to Teach With AI.

Questions teachers ask

Why is this free?

Because it gets you onto my newsletter, where I publish a practical AI workflow for teachers every week. That is the whole trade, stated plainly.

Can students share a conversation back with me?

Yes. A "share this chat with your teacher" button saves that one conversation and gives the student a link to hand you, which turns the bot into an assignment you can grade. Ask for initials or a class code as the label, never full names.

What happens if this tool disappears like the GPTs did?

Your instructions are yours: keep them in a doc you own, and they paste into any future tool in minutes. The prompt is the asset. The platform is just the socket, this one included.

Can I edit a bot mid-semester?

Anytime. The student link never changes, so you can sharpen the instructions in week eight without re-sharing anything.
