Why it matters for Christians

When a long conversation exceeds it, the model can lose track of what was said earlier, including your instructions.

What to do

In a long chat, repeat your key instructions, such as “quote the verse and give the reference,” or start a new conversation. Paste the passage you are studying so the AI answers from the text in front of it.

Ask about this word

Ask how it applies to you.

Lumin answers in a few sentences and names the passages it rests on. Each verse it cites is checked and shown in full below the answer, so you can read it yourself.

Press Enter to ask. Shift and Enter starts a new line.
