About

Bio Architect

Features
Read full description

Bio Architect is an offline biography evidence studio for professionals, speakers, researchers, editors, and communications teams. Build one canonical subject dossier, trace publishable claims to source records, and shape distinct bios for each audience without sending sensitive material to a server. Start with evidence, not a fill-in template. Record employer pages, registries, publications, programs, credentials, interviews, or private document notes with provenance, visibility, dates, locators, and relevant excerpts. Turn those records into structured claims with a canonical value, editorial status, and explicit source links. Create separate variants for organization websites, conferences, media contacts, professional profiles, spoken introductions, grants, and bylines. Each draft has its own point of view, word target, selected claim map, and editor note. Review before publishing: - Find claims with missing or removed sources - Surface conflicting values for the same biography fact - Flag disputed claims and stale source reviews - Catch numbers that are not mapped to selected evidence - Review point-of-view drift and unsupported promotional language - Save immutable checkpoints and compare revisions word by word Export only what the recipient needs: - Clean biography text - Redacted editorial fact-check packet - Complete private dossier archive Bio Architect adapts its information architecture for iPhone and iPad. Everything is stored locally with SwiftData. There are no accounts, network requests, analytics, ads, tracking, third-party SDKs, or generative AI. The app never writes biography copy for you and never claims to verify a person automatically.
