Leistera vs Custom GPTs: a GPT on files is not the title page
A Custom GPT with uploaded norms is fast, and often forbidden the moment the brief must go in. ChatGPT Enterprise does the same job more cleanly. The job remains: chat over the stack someone chose. Not competence. Not title page. Not drawing.
| Criteria | Leistera | Custom GPTs |
|---|---|---|
| Control | Pilot, report, hosting agreed | Whoever built the GPT |
| Valid edition | First step | What sits in the GPT |
| Proposal | Sections with source, Word | Chat, copy-paste |
Choose Leistera when
Choose Leistera when the bot fails your specialist questions on edition and page.
Choose Custom GPTs when
Choose a Custom GPT when the stack is small, deliberately chosen, and will not be signed.
Frequently Asked Questions
- We already have a norms GPT. Is that enough?
- If it passes 50 of your own questions with document, edition and page: yes. Most do not, because the wrong file sits in the stack.
