Google Cloud Partner
Need a ChatGPT Enterprise alternative for a Google Workspace org? Move your enterprise AI to Gemini, native in Docs, Gmail, Meet and Sheets, grounded on your own Google data. This is an enablement and change-management programme, not a data migration, run by a Google Cloud Partner.
Moving from ChatGPT to Gemini is an enablement project, not a data migration. There is no enterprise AI dataset to lift. Codimite, a Google Cloud Partner, switches your licensing to Gemini for Google Workspace, rebuilds your prompts, custom GPTs and API assistants as Gemini and Vertex AI capability, re-grounds them on your Google data, and drives user adoption. The work is change management: licensing, rebuild and adoption.
Why migrate
Standardising on Google Workspace means Gemini lives inside Docs, Gmail, Meet, Sheets and Slides, no separate AI tab.
Gemini answers from your Drive, Gmail and Workspace content; on Vertex AI you ground on your own enterprise data.
Gemini's long context window handles large documents and datasets in one pass.
Gemini for Google Workspace is priced per seat in the Workspace stack.
Productivity, identity, security and AI under the Google admin console.
What we rebuild
| ChatGPT artifact | Becomes in Gemini / Vertex AI | Notes |
|---|---|---|
| Saved prompts | Gemini prompt library | Re-authored and tuned to Gemini |
| Custom GPTs | Gemini Gems / Vertex AI agents (ADK) | Rebuilt; Codimite uses Google ADK + n8n |
| OpenAI API assistants | Vertex AI / Gemini API integrations | Re-implemented against Vertex AI endpoints |
| Knowledge / file grounding | Grounding on Workspace & Vertex AI data | Re-pointed to your Google data sources |
| Admin & governance policies | Google admin console policies | DLP, access, retention re-created |
| ChatGPT conversation history | Does not transfer | No portable store; conversations are not lifted |
This is an enablement engagement, we rebuild capability against Gemini, we do not move an AI dataset.
Our process
We inventory ChatGPT usage, prompts, custom GPTs, API assistants, power users, and confirm Workspace readiness.
We map each use case to a Gemini or Vertex AI equivalent and define grounding and governance.
We re-author prompts, build Gemini Gems and Vertex AI agents with Google ADK + n8n, and re-implement API assistants.
A champion group validates value on Gemini before scale.
Licensing switch, role-based training and an adoption playbook.
Adoption tracking and support through the change window.
