Every time you cook is evidence.

The one rule worth knowing

Recording a cook and changing a recipe are never the same act.

When you say “it needed fifteen minutes longer”, that is written down against the exact version you cooked. The recipe does not move. It still says what it said, because one cook is not yet a conclusion.

When you decide the recipe should change, Suppermode writes a new version and leaves the old one intact, along with every cook logged against it. No recipe and no cook is ever overwritten. That is why “why does this say 425°F?” has an answer later instead of a guess.

What you can ask for

• Save this recipe

  From something you dictated, pasted or worked out in the conversation. It becomes yours, at version 1.

• What's in my crispy potatoes?

  Finds the one you mean by description and reads it back, with the version number you are on. If two recipes could be meant, it asks rather than guesses.

• I cooked it tonight, and it ran long

  Records the cook with your note, against the version that was current that day — even if you log it on Wednesday for a Monday.

• What have I learned about this?

  Your cooks for that recipe, each labelled with the version it was actually cooked against, so observations from different versions are not merged into one conclusion.

• Update it to reflect that

  Appends a new version, and records which cooks motivated it. It will suggest the change and wait for you rather than editing on its own.

• Why is my bread recipe the way it is?

  The chain from version 1 to now, each step labelled with the reason it exists and the cooks behind it.

• My oven runs hot, and one of us can't eat shellfish

  Kept as a short profile and read before it writes or adapts a recipe for you, so you are not re-explaining your kitchen every conversation. Your words, not its inference from them. This is the one thing here that is replaced rather than versioned: change an answer and the previous one is gone, which is why your assistant asks before it writes.

Setting it up

Suppermode works through your assistant, and the website is there for the same cookbook when you would rather click than talk. Adding it to ChatGPT or Claude takes a minute and has the address and the steps for both.

You can also do all of it here without an assistant: save a recipe, log a cook, read the history, and change the recipe citing the cooks that led you to.

What it does not do

Deliberately, so that what it does do stays trustworthy:

• No pantry, no meal planning, no shopping lists

  This is a record of what you cooked and what you learned, not a kitchen management system.

• No importing from a URL or a video

  Recipes come from you — dictated, pasted, or written here. A recipe you did not choose to keep is not evidence of anything.

• No photos

  Text only, for now.

• Private unless you share a recipe

  Your cookbook is yours alone. No other account can reach it — somebody else’s recipe ID comes back as not found rather than as refused, so knowing an ID confirms nothing. To send one recipe to somebody, share it from its page on the website: they get a link that shows the recipe and nothing else, with no account needed, until you stop sharing it.

• It never reads your conversations

  What reaches Suppermode is what your assistant sends when it uses one of its tools: the recipe or note you are saving, the words you searched with, and the profile answers you confirm. Not the conversation around them. What your assistant does with what it reads back is covered on the privacy page.

Getting your data out, or deleting it

Export everything as JSON from your account page at any time: every recipe, every version, every cook, where each recipe came from, and your cook profile. Deleting your account removes all of it immediately. The privacy page says exactly what is stored, what is not, and the two places a copy can persist after deletion.

If something is wrong

Email [email protected]. A recipe that lost a quantity, a cook logged against the wrong version, or an assistant that edited when it should have asked are all worth telling us about — the last one especially, because it is the thing this product is built not to do.
