Everything Aiter writes traces back to what it was allowed to read. So the ten minutes you spend choosing source material is the highest-leverage ten minutes in the whole product.
What you can attach
The new campaign window takes more than a URL, on paid plans:
- Extra links. Articles, docs, reviews, competitor pages, anything with a URL.
- Files. PDF, Word, text and audio, up to 20MB each and ten per campaign. Files vanish after seven days; the brief keeps what it learned.
- YouTube. The transcript gets read, so a founder talk or a product walkthrough becomes source material.
- A manual description. Instead of scraping, describe the product yourself. Twenty characters minimum, though a paragraph or two serves you far better.
- A brand or product name, if the site does not make it obvious.
There is a token meter under the inputs showing how much you have loaded, with a ceiling. Going over asks you to trim rather than silently truncating, which is the behaviour you want.
The sources that actually improve a brief
Ranked by how much they change the output, from experience with how briefs come out:
A sales deck or one-pager. These say plainly what your website says decoratively. Positioning, differentiators, objections, pricing logic. If you attach one thing, attach this.
A recorded demo or founder talk. People explain their product better out loud than they write it on a homepage. Transcripts pick up the phrases you actually use in the room.
Your best case study. It contains the outcome, the objection and the proof in one document.
Competitor pages, as extra links. This gets contrast into the brief from the start rather than waiting for a research report.
Review pages. Real customer language, immediately.
What is not worth attaching
Your entire site. Twelve links from the same domain mostly repeat each other, and they eat the budget you could have spent on the deck.
Legal and policy pages. Accurate, and they will teach the brief nothing about what makes you worth buying.
A pitch deck aimed at investors. It describes a market opportunity, not a product, and the resulting brief will write to investors. This is a surprisingly common cause of copy that sounds like a funding round.
Anything already covered by the homepage. Duplication does not reinforce, it just spends the meter.
When links fail
Some sites block automated readers. When a link cannot be opened you get a per-link status, and the choice to continue without it or cancel with no charge. You are only charged for the sources that were actually read.
The same applies to YouTube: no transcript, no ingestion, and the ones that failed are dropped from the charge.
If your own site blocks the read entirely, the brief comes back thin and Aiter says so, refunds you, and offers the manual route. That is the moment to switch to manual input and paste your best description.
The manual route, done properly
Writing the description yourself is not a downgrade if you write it well. A useful shape:
What the product is, in one sentence. Who buys it, specifically. The three things it does that matter most. What people used before you and why it was worse. What you charge, roughly. How you sound.
That paragraph beats a scrape of a vague homepage every time.
