How long does it take to migrate from CustomGPT to AskVault?

We suggest planning for about two weeks: set up AskVault and index your content in the first week, test it side by side with CustomGPT, then switch production and cancel CustomGPT once the answers match or beat your CustomGPT baseline.

Can I bring my existing bot instructions from CustomGPT?

Yes. Paste your existing instructions into the System Prompt field on your agent's Playground page, test them there, then publish.

What does AskVault add when I move from CustomGPT?

One agent deployed across your website widget, WhatsApp, Slack, Discord, email and more; answers grounded in your content with the source list shown by default; and HMAC identity verification for widget visitors.

Common pitfalls

Forgetting to cancel CustomGPT. Calendar reminder for day 14.

Channel surprise. Each new channel behaves differently from a website widget. Test WhatsApp/Slack rollout carefully.

Identity mismatch. Re-issue HMAC secrets.

If done well, no. Your visitors still get a chat widget on the same pages.

Can I migrate progressively (channel by channel)?

Yes. Start with widget; add channels over weeks.
