What the tools can and cannot change

Your assistant reaches langweave through five tools on the Standard plan, and two — neither of which writes — on Free (Plans). On Standard, two of them write, and both write the same kind of thing: an event — one line in your history saying what happened to one word, and when. langweave passes each event on to lexmem, which keeps your memory.

What your assistant can do

• Record that it used a word (log_exposures): glossed, bare, or inside a sentence. This is what moves words along — see word states.
• Pass on what you asked (log_exposures): that you asked what a word means, or how to read it.
• Pass on what you said about a word or a grammar point (update_item): that you know it, or want it back in learning. The instructions allow this only when you say so, never for a word that was merely used.

Each of these adds events to your history. Your word states are worked out from that history — nothing sets a state directly, so every change to your profile has an event behind it, with a time.

What your assistant cannot do

• Edit or delete your history. Events are only ever added. A mistaken “I know this” is undone by a later “put it back in learning”, which is another event.
• Change your settings. The limits in the digest — how much to weave, how many new words, the thresholds — are changed only in the app.
• Choose or switch your language. Enrolling in a language, and choosing which one is active, happen only in the app at app.langweave.tech. The language you will spend a year learning is your decision, not one a model makes in passing.
• Add words to the word list. Each language’s list is built from dictionaries and released as a whole, by lexmem; a logged word that is not in it is reported back as unknown and recorded nowhere.
• See your account. The tools know an account id and nothing else — not your email, not your name.
• See the conversation. What reaches langweave is the list of logged words, never the text around them.

When it gets it wrong

Your assistant can mis-log: miss a word, or record an exposure for a word it did not really use. The rules are built so that this is cheap. A missed log means a word takes a little longer; an extra one is one sighting towards a count of eight. If a word reaches known that you do not know, say so, or ask what it means — either puts it back.
