How AI Cashback Works: Less, Explained

You ask Claude which running shoes to buy. It suggests a pair, finds a working coupon code, and tells you that buying through its link puts $4.20 back in your pocket. That is Less. This page explains exactly how it works — including how we get paid, because a savings tool that hides its own economics is not a savings tool.

Less is a connector (an MCP service) for Claude and ChatGPT. You connect it once. After that, when you ask your AI about anything you are about to spend money on — shoes, a VPN, a project-management tool — the AI can call Less to check three things: validated coupon codes, cashback, and honestly compared alternatives. No browser extension, no new app, no separate account to check daily. It works inside the chat you already use.

Here is how Less compares to the cashback tools you may already know:

Connecting it

Claude: open Settings, go to Connectors, add Less. Approve the connection when Claude asks. Then just talk — "I need a winter jacket under $200" is enough.

ChatGPT: open Settings, go to Connectors, add Less. Approve it. Ask about your next purchase as you normally would.

That is the whole setup. There is nothing to install in your browser and nothing running in the background.

Where the money comes from

Merchants pay commissions for referred customers. They have done this for decades through affiliate networks — the same programs behind coupon sites and cashback extensions. When you buy through a tracked link, the network reports the sale and the merchant pays a commission.

Most tools in this space keep that commission. Less splits its net commission with you 50/50, and shows your share in dollars before you click anything.

Worked example. You want shoes that cost $120:

• Less finds a validated $15 code. You pay $105.
• The merchant's affiliate program pays 7% on the $120 order: $8.40 net commission to Less.
• Less keeps $4.20. You get $4.20.
• Total: $19.20 back on a $120 purchase — 16% — for buying the thing you were buying anyway.

The merchant funds all of it. It is their customer-acquisition budget; the only question is whether a middleman keeps your half.

The honesty rules

Any tool paid by commission has an obvious conflict of interest: recommend whatever pays best. Less handles this with three rules, not a promise.

1. Best net value for you wins. Always. Rankings are computed on your net outcome — price after codes and cashback, and for services, what you actually get for it.
2. Commission is only a tiebreaker. It can order options only when they land within about 3% of the same net outcome for you. It cannot promote a worse deal past a better one.
3. Zero-commission options are in the catalog and can win. Mullvad pays Less nothing. When it is the best VPN for your case, Less recommends it and earns $0.

Every ranking decision is logged for audit. And every recommendation carries an FTC-style disclosure telling you a commission may exist and what your share is. The full policy is at sayless.is/legal/disclosure.

What happens when you click

Attribution is deliberately boring. Less gives your AI a tracked link. You click it and check out in your own browser, on the merchant's own site. No extension, no auto-applied codes, no scraping — codes come from official affiliate network feeds, which is why they are validated rather than crowdsourced guesses.

If you do not click the link, there is no commission and no cashback. That is the entire mechanism, and it is also the limit of what Less can see about your purchase.

The wallet: pending, locked, paid

Cashback is slow. Here is why, plainly.

If you return the purchase, the merchant claws the commission back and your cashback reverses. Less never pays out money before the network pays Less — that is the honest reason the wait exists, and we would rather say so than pretend the delay is a mystery.

Privacy, and what Less does not do

Your conversation stays between you and your AI. Less only sees the queries the AI sends it — "trail running shoes, size 10, under $150" — not your chat history, your files, or anything else you have discussed. There is no browser extension watching your tabs.

What Less does not do, as of July 2026: no Amazon (v1), no price tracking, no selling of your data. The business model is the commission split described above. That is the only revenue.

Common questions

Is the AI biased toward paying merchants? The ranking rules above are the guardrail: net value wins, commission breaks ties within ~3%, and decisions are logged. The Mullvad case is the proof — Less recommends it and earns nothing.

Why a $10 minimum withdrawal? Payout fees on tiny amounts would eat your balance. $10 keeps the transfer worth making.

What if a code fails? Codes come from official network feeds and are validated, but merchants pull promotions. If one dies, ask your AI to check again — Less returns what is currently live.

The short version

• Less is a connector for Claude and ChatGPT. Connect once; your AI checks codes, cashback, and alternatives when you shop.
• Merchants pay affiliate commissions. Less splits its net commission with you 50/50, shown in dollars before you click.
• Best net value wins, always. Commission only breaks near-ties (~3%), zero-commission options can and do win, and every ranking is logged.
• You check out in your own browser via a tracked link. No extension, no scraping, no auto-applied codes.
• Cashback goes pending → locked (30–90 days) → paid via Wise or PayPal, $10 minimum. Refunds reverse it. Less pays you after the network pays Less.
• No Amazon in v1. No price tracking. No data selling. Less sees only the queries your AI sends it.
