get_core_profile — loads your standing profile once at the start of a session: verified, high-confidence facts (nothing sensitive), the people and things that come up most, and your active projects.

search_memories — finds memories relevant to a question, each with a verdict on whether it may be stated as fact (see Confidence, conflicts and "assertable"). It also finds matching memories other people shared with you, and says who shared them.

get_context — a ready-made block of what your own vault holds on a broad topic ("what do you know about my car?").

add_memory — stores one fact. import_memories stores many at once (up to 50 per call).

get_memory — reads one memory in full: entities, action items, confidence, timestamps and any attached files.

update_memory — corrects a memory, keeping the old value in history. forget_memory erases one for good; there's no undo. Your assistant should confirm first, and erasing several in a row needs your explicit go-ahead.

get_as_of — what was true about something on a given date.

get_memory_history — every value a memory has held and when JustOnce believed it.

get_relationships — walks the graph of how the people, organisations and places in your memories connect ("how do I know Priya?").

find_related_entities — lists the people, organisations, places and accounts your memories mention, or checks how well-supported one stored value is (an address or account number) before your assistant relies on it.

store_document — saves a small file the assistant holds, plus the facts it read from it. JustOnce doesn't OCR, so your assistant passes along what the document says.

request_upload_link / check_upload_link — gives you a one-time browser link to upload an original file (up to 25 MB; it works once and expires after 15 minutes), then checks when it lands.

fetch_document — retrieves a stored file over the signed-in connection.

list_shared_spaces, list_space_memories — see your spaces, who's in them, and everything shared into a space.

open_shared_space — creates a space and can ask to invite people by email as viewers, including people who don't have an account yet.

share_memories — asks to share memories into a space, or takes a share back.

close_shared_space — archives a space you own and ends everyone's access. You can reopen it in the app.

search and fetch — the citable-results tools ChatGPT connectors use. Other assistants use search_memories and get_memory instead.

ChatGPT and Codex don't get get_core_profile, get_context, get_as_of, get_relationships or find_related_entities, and some memories are kept out of them. See Connect ChatGPT.
