My AI loses my funnel details before the sales sequence is finished

I start the morning with a clear job: finish the launch funnel for my small SaaS add-on before the end of the day. I have the buyer notes, the offer, the old testimonial, and three rough email ideas in a doc. The first AI pass is useful. It sharpens the hook, names the buyer pain more clearly, and gives me a sales page section I would actually edit instead of delete.

By lunchtime I am six or seven prompts deeper. I ask for the tripwire email and it starts talking to a broader startup audience instead of the tiny founder I wrote the offer for. I correct it, paste the buyer notes again, and get something workable. The small win is that the subject lines are better than mine. The problem is that I am now spending as much time steering the chat as writing the funnel.

In the afternoon I try to connect the sales page, email sequence, and upsell. That is when the drift shows. The proof is phrased differently in each section. An objection I rejected earlier comes back as if it is new. The offer promise gets softer in the emails and bigger on the sales page. None of it is obviously broken, which makes it harder to trust. I keep scrolling up, copying bits from earlier messages, and rebuilding the brief by hand.

By the end of the day I have a funnel draft, but not a clean one. I can ship it only after another review pass because the AI helped with the words but did not preserve the decisions. What I want is simple: a way to lock the buyer, offer, proof, objections, and stage rules in one place so every AI draft is checked against the same funnel memory before I send anything to my list.
