Tools 8 found in our last check

• write_notebook_page

  Writes one handwritten study page into the user's Wren notebook: editable ink, not the user's own handwriting. target.noteId adds it to that note; else a new note. Wren emails the user a link to their first note saved here. A full page (not for verbatim): 110-140 words in 6-8 bl…

• plan_notebook

  Plans a 1-30 page handwritten Wren notebook and writes its cover and contents (page 1; over 8 pages: a cover page and contents pages). The cover is not a slot: slots are the content pages, numbered from 1. Each slot's page is written by write_notebook_page with target.noteId + p…

• list_recent_notebooks

  Returns the user's latest notes, newest first: id, title, subject, pages, last edit, the outline of pages Wren wrote, and the note this chat has been writing to.

• get_note

  Returns one note's title, subject, page size and its pages (number, id, ink stroke count, whether Wren can add ink to it). Page numbers match target.pageNumber in write_notebook_page and draw_figure.

• draw_figure

  Draws one standalone figure in the user's Wren notebook, large on its own page: a graph, labelled diagram, chart, table, timeline, flowchart, mind map, concept map, number line or shapes. Figure only, no text blocks (write_notebook_page pages can hold figure blocks next to text)…

• get_profile

  Returns the stable Wren account id (Firebase uid) and basic profile of the currently linked account; a returned id confirms the account is linked.

• connect_account

  Link the user's Wren account so authored notes land in their notebook. Returns the linked uid when a credential is present; otherwise explains that account linking must be completed first.

• list_notes

  Lists the user's Wren notes, most recently edited first, with id, title, subject and page count. The noteId works as target.noteId in write_notebook_page and draw_figure, and as noteId in get_note.
