Plot Spark ignites your next idea - with a single roll. Whether you're working on a novel, a short film, a tabletop RPG campaign, or just need a story for tonight: Plot Spark instantly delivers a character, a conflict, and a setting - random, unexpected, and inspiring. HOW IT WORKS Pick a kit, roll the dice - and get a complete story prompt with character, conflict, setting, and a wild twist. Sounds too simple? That's exactly the point. Prefer instant results over a dice animation? Turn the roll animation off and get straight to the prompt. ELEVEN KITS, EVERY GENRE Plot Spark ships with eleven curated kits - from neon-soaked noir and cosmic comedy to high-seas adventure, Cold War espionage, and Victorian hollow-earth expeditions. And you can create your own kits and fill every slot with your own ideas - tuned to exactly the tone you need. JOURNAL & MARKDOWN EXPORT Save every hit straight to your journal. Write notes, develop the idea, or let it simmer - your best prompts won't get lost. Export any entry, or your whole journal, as clean Markdown and keep working in your favorite writing app. FROM SPARK TO GAMEBOOK Your exported prompts are plain Markdown - the same format Story Weaver speaks, our free open-source language for writing branching gamebooks with choices, dice, and fights. Grow a rolled prompt into a full playable adventure: github.com/ComicSans/story-weaver NO SUBSCRIPTION. NO ACCOUNT. Plot Spark needs no internet connection, no login, and no subscription.

Bio Architect
Read full descriptionHide 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.
