    analyse_transcriptCompare one speaker in a meeting transcript with public founder and operator interviews and return the report as data: speaking type, style positions, similar well-known people, standout habits and takeaways. transcript: the whole text, one speaker turn per line ("Name: words"). speaker: one speaker label as it appears in the text. name: the person's name when the label is generic (Me, Them, Speaker 2), or "You" when the speaker is the user; required for a generic label other than Me. role: "answering" when they were pitching or answering questions, "asking" when they mostly asked them. Needs at least 300 words from the speaker and at most 15,000 words in all; usually takes under a minute, up to about two minutes when the service is starting up. Clients that support MCP Apps also show the visual report.
    open_in_terminalReturns a curl command that uploads a local transcript file (.docx, .txt, .md or .vtt) to FounderBrain for analysis, for clients that run commands on the user's own computer, such as Claude Code and Codex. path: the file's full local path. speaker, name and role: the speaker label to analyse, the person's name when the label is generic, and "answering" or "asking". Without a speaker the command only lists the speakers and their word counts.
    check_transcriptList the speakers in a meeting transcript and how many words each said, without scoring anything. transcript: the whole text, one speaker turn per line ("Name: words").
