Mintlify Pro costs 250 USD per month. We wanted something similar (AI assistant and nice UI), but fully customizable and cheap. So we built GibsonAI docs in 1 day for about 50 USD.

How we did it:

Used Lovable for UI components + rendering MDX beautifully (Markdown stored in GitHub).

Built an AI Agent for docs using Agno + Memori → personalized Q&A and “smart educator.”

Stored embeddings in LanceDB and metadata in our SQL DB.

Bonus: We can share our reusable design templates and source code so you can deploy on Vercel (or anywhere) and skip Lovable costs.

Would love feedback on what features you would add or change?
