Cost & access
BrewMark does not sell products or process payments. Its tools return grind settings and, when someone is choosing a grinder, a shortlist that links only to BrewMark's own buying guides on brewmark.io. Those guide pages carry retailer links (Amazon Associates), so BrewMark may earn a referral commission on purchases made there; nothing is bought inside ChatGPT.
Declared limitations
- Coffee question with no grinder involved: should answer without BrewMark
- Unrelated request: BrewMark should not be called
- Purchase request: BrewMark does not sell grinders and should not act

Description
From the marketplace listing
BrewMark is a home coffee brewing tool. It gives the grind setting to use on your own coffee grinder, for every brew method from espresso to cold brew. It covers 200+ home grinders, including Baratza, Fellow, Comandante, 1Zpresso, Timemore, Niche and DF64. Ask things like: - "What setting should I use for pour over on my Fellow Ode Gen 2?" - "The recipe says 18 clicks on a Comandante C40 MK4. What's that on my Baratza Encore?" - "Which grinder should I get for pour over under $200?" Answers come as a card: the setting drawn on your grinder's dial, every brew method on one chart with a starting recipe, and "too sour" / "too bitter" buttons that move the dial a step at a time. Tell it how the cup tasted and it gives the next setting to try; say it's dialed in and the assistant can remember it for that coffee. Shopping for a grinder, you get a shortlist with photos, approximate prices and a link to each one's BrewMark buying guide. BrewMark maps every grinder onto one shared 0 to 100 grind scale, so a setting quoted for one grinder can be translated to another. Intended for home brewers dialing in a grinder they own, following a recipe written for a different one, or deciding which grinder to buy. Limitations: settings are starting points, not guarantees. Burr wear, bean density and roast level shift the right setting, so expect to adjust by taste. BrewMark does not give settings for grinders where its data is not good enough to publish (for example the Kafatek Monolith), and says so rather than guessing. Prices are approximate US list prices. It does not sell anything or need an account. When you report how a cup tasted, BrewMark keeps an anonymous record (grinder, brew method, setting, taste, and the coffee's name if given; no IP address or identifier) to improve starting settings for particular coffees.

--- name: get-started description: Grind settings for the user's own coffee grinder, and help choosing one to buy. Use when someone asks what grind to use on their grinder, needs a recipe's grind setting translated to the grinder they own, or is deciding which grinder to get. --- # BrewMark grind settings BrewMark covers 200+ home coffee grinders. It can do four things: - **Translate a setting between grinders.** A recipe says "18 clicks on a Comandante" and the user owns a Baratza Encore: call `convert_grind_setting`. - **Give the settings for one grinder.** The user wants to know what to use for espresso, pour over, French press and so on: call `get_grinder_chart`. If they named a brew method, pass it as `method` so the card leads with it and its starting recipe. - **Say what to try next after tasting.** The user brewed at a setting and it tasted sour or bitter: call `dial_in` with the grinder, the setting, the result and the brew method if they said it. If they say it now tastes good, call it again with result `good`. - **Help choose a grinder.** The user is deciding what to buy: call `find_grinder` with the brew methods, budget, hand or electric, and must-haves they mentioned. Leave out anything they didn't say. BrewMark doesn't sell grinders; each pick links to its buying guide on brewmark.io. Don't use it to place an order. Users name grinders however they like. Pass the name as they said it. If the tool reports more than one match (for example "Comandante" covers the MK3 and MK4), ask the user which one they have. Don't guess. Every number is a starting point. Burr wear, bean density and roast change the right setting, so say that once and suggest adjusting by taste: finer if sour or fast, coarser if bitter or slow. Answers show as a card with the numbers drawn on the grinder's dial. Don't repeat every number from the card; give the advice around it. The card has "Too sour" and "Too bitter" buttons; if the user taps one, its new suggestion reaches you as context, so follow it.
Release notes
New: tell it how your coffee tasted and it gives the next setting to try, on the card, with a Dialed in button. Settings for your grinder can now take the roast into account.
