A community of real testers, run by its members. A real person picks your product and uses it, then posts an honest review on the marketplace under their verified profile. A moderator checks every one.

02The request
A seller asks for 1 to 50 tests and pays for all of them upfront in lum, Sharelum’s points. Testers know the lum is already there. If a review never gets posted, the spot goes to another tester, so the seller never pays twice.
03The handoff
Testers browse open requests and claim the products they genuinely want to try. They get their lum the moment they claim, before they’ve even tried the product, so the lum can’t depend on the rating. Then they buy it, use it and review it honestly on the marketplace. If the review isn’t verified, the same lum is taken back.
04Real use
Digital products need no delivery, but they still need real use: a 500-word piece takes under a day, a 2,000-word book about two. A physical product has to be bought, delivered and used before anyone can honestly review it, so it gets 30 days. Delivery is up to the courier, not us, so thanks for your patience.
05The verdict
Ratings run from one to five, and the tester picks the one that matches what they found. Nobody is told what to write, and the lum is the same either way. A one-star review tells the seller what to fix. That’s why five stars here mean something.
06The check
Every review is checked where it’s posted, on the marketplace. Verified, the lum stays. Not posted, not genuine, expired or cancelled: the same lum is taken back and the slot reopens for someone else.
07Everyone
There’s no wall between the two sides. The people who ask for tests earn their lum by testing. It’s open for products sold on Amazon and SHEIN, plus a separate hub for books, and adds one marketplace at a time.
How it works
Sellers need honest reviews. Lots of people like trying new things. On Sharelum you earn lum, Sharelum’s points, by testing other people’s products — buy it, use it, review it honestly on the marketplace — and spend it to get yours tested. Lum can’t be bought.

You post it on Amazon or SHEIN (books: Amazon) under your verified profile. Sharelum never hosts reviews — there’s nothing to paste here.
One star or five: nobody tells you what to write, and the lum is the same either way. Critical reviews are welcome.

That is the whole loop. Test first, then ask.
Lum, explained
Lum is Sharelum’s points — short for lumen, the light in our mark. No money changes hands between members: you earn lum by testing things and reviewing them honestly, and spend it to get your own products tested. Five cards, one idea each.
Lum is the only currency here. Members trade it for time and honest words — never for money, never for stars.
1 / 5
The first 200 start with 1,600 lum, enough for their first tests.
The difference
A review farm sells five stars. Sharelum rewards real use and an honest review, whatever it says. Here is the difference, question by question.

For everyone
For sellers
Your reviews come from people who chose your product and really used it, not from a script. A moderator checks every one.
For testers
Pick what you’d actually use and say exactly what you found. Your lum lands the moment you claim, whatever rating you give. If your review isn’t verified, it’s taken back.
For shoppers
Every review comes from someone who used the product, under their own verified profile. Critical ones too, because that’s how sellers improve.

A community of real product testers, run by its members: a real person picks your product, uses it and posts an honest review on the marketplace under their verified profile, and a moderator checks every review.
Anyone who sells online, and anyone who likes trying new things. Most members are both — they ask for tests of their own products and earn lum by testing other people's. Shoppers win too: more reviews from people who really used the product.
No. Lum lands the moment a tester claims a product — before they've used it or formed an opinion — and it's the same for one star or five, so there is nothing to gain from flattery. Nobody is ever paid for a positive rating, critical reviews are welcome, and a moderator checks that every review is genuine. If it isn't, the lum is taken back.
Yes — that's the whole point. Testers post their review on Amazon or SHEIN (on Sharelum Books: Amazon) under their verified profile. Sharelum never hosts reviews: no ratings, no review text, nothing to paste here. If the review isn't posted or isn't verified, the lum is taken back and the slot reopens for another tester, so the seller doesn't pay twice.
Never. The tester gives the stars that match what they found, and nobody tells them what to write. A review only has to be honest and say enough to be useful. A one-star review that explains what isn't ideal gives the seller a chance to improve.
Lum is how the community rewards testing — no money changes hands between members. You claim a product you'd use and its lum lands in your balance straight away. Then you buy it, use it and post an honest review on the marketplace. Once a moderator verifies the review, the lum stays; if it isn't verified, or the test expires or is cancelled, the same amount is taken back and returned to the seller. You spend lum to get your own products tested. A typical test is around 1,000 lum and you always see the exact amount first. The first 200 from the waitlist start with 1,600 lum — enough for their first test on day one.
Long enough to really use it. Digital items need no delivery but still take a day or two, depending on the effort: a 500-word piece in under 24 hours, a 2,000-word book in about two days. Physical products get 30 days, delivery included — the tester buys it, waits for it to arrive and uses it before reviewing. Delivery is up to the courier, not us, so a little patience goes a long way. Each test can be extended once if needed.
Every test has a deadline. If the review isn't posted and verified in time, or the test is cancelled, the lum is taken back from the tester and returned to the seller, and the slot reopens for someone else — so a seller never pays for a review that didn't happen.
No. Marketplaces don't endorse Sharelum or any similar platform, and we won't pretend otherwise. What we control is how Sharelum is built: reviews are written honestly and never paid for a positive rating, critical reviews are welcome, there are weekly limits on tests, moderators remove generic, AI-written or fake reviews, and accounts that abuse the system are closed. Following each marketplace's current rules is every member's own responsibility.
No — and be wary of anyone who does. Every test starts with a real person choosing your product, so nobody can promise how many will. What we can promise is that you only pay for what happens: unclaimed slots, expired tests and reviews that aren't verified all hand the lum back.
You can't claim your own listing. Other members' products are fine — including a seller who tested yours — as long as you'd really use it and review it honestly.
Up to five open tests at a time, and up to eight new ones in any rolling week. The limits keep everyone focused on using each product properly instead of rushing through a pile of them.
In the products app, anything you sell on a supported marketplace — Amazon and SHEIN today — and you pick the marketplace for each product. On Sharelum Books, a book you wrote or publish. Paste the listing link and our team checks it before it goes live, so testers only ever see real, available products.
Yes. Cancel the plan from Billing in the app, or delete the account in Settings → Security. Deleting asks for your password, and for a two-factor code when two-factor authentication is on. It signs you out, clears your lum and removes your name and email. A test that was already verified stays on the other member’s record as “Former member”. The first 200 from the waitlist aren’t asked for a card during their 3 free months. Lum has no cash value and doesn’t survive a closed account. Email support@sharelum.com when you can’t sign in.
Amazon and SHEIN, for now. There is one products app at app.sharelum.com, and you pick the marketplace each product sells on. Sharelum Books, at books.sharelum.com, is a hub just for authors and readers. We add marketplaces one at a time, so each starts with real members and moderators.
Yes — Sharelum Books. Readers choose the books they actually want to read — a free ebook (ARC), on Kindle Unlimited or as a paperback — and post an honest review on Amazon under their verified profile. A moderator checks every review, like everywhere else.
The first 200 people invited from the waitlist get 3 months free with no card, plus 1,600 starter lum — then $5 a month, locked in for life. Everyone after them starts with a 7-day free trial, then $10 a month.
Join the waitlist for your hub — the products app or Books. Invites go out in batches to the first two hundred people on the waitlist, and every friend who joins through your link moves you ten places up the line.
