DEEP IN

For people who publish reviews

If you write about language apps, here is what we can offer

This page is for review sites, comparison articles, "best apps" round-ups, newsletters and teachers who publish tool lists. It is not an ad — it is so you have something to work with, if Deep In is worth a line in your list at all.

The terms

$10oncefor every reader who arrives through your link and takes a paid subscription
$1a monthfor as long as that person stays — not one payment, but every month they keep using it
0payout thresholdpaid monthly with no minimum; we cover the transfer fee

Full terms are on the programme terms page. For comparison: most programmes in this category pay once and stop.

See the product first

Nobody can review what they have not used. Deep In's first day runs without an account and without a card, which is enough to form an opinion. If you need full access for longer, write and we will send store promo codes — they redeem without a card and cost you nothing.

What we do not ask for. We do not ask for a link, we do not approve your copy, and we do not make praise a condition. If your conclusion is that Deep In is not for your readers, write that. A site that says no is worth more than one that says yes to everything.

The facts a review needs

Prices and what is included$18 Basic, $29 Deep, the day-one limits, and why there is no free tier Compared with FluentUincluding where FluentU wins Compared with LingopieLingopie is cheaper, and we say so Why we are not Duolingonot a course — and not a replacement for one

In short: Deep In teaches English only, needs a base level, works with any YouTube video, and costs more than most. The interface is in eight languages.

How to start

The link and code are already in the app: Profile → Invite. If you would rather agree something in words, need promo codes, or want a different arrangement — write.
