Knowledgebase Jumper 1.0.0

First public release.

Point the app at a folder of documents and it builds a searchable index on your
machine, then answers questions about them with a citation on every claim that
opens the exact file and page behind it.

Downloads

Platform	File	Notes
macOS 11+ (Apple Silicon)	Knowledgebase-Jumper-1.0.0-arm64.dmg	Signed and notarized; installs without a Gatekeeper prompt. No Intel build yet.
Windows 10/11 (x64)	Knowledgebase-Jumper-1.0.0-x64.msi	Not code signed yet, so SmartScreen warns on first run: More info then Run anyway.

What's in it

• Indexes .pdf, .docx, .pptx, .xlsx, .md and .txt, with spreadsheets indexed
  per sheet and decks per slide so citations can point at one sheet or slide.
• Six editable chat modes — Ask, Augment from Web, Timeline, Simplify, List, Scholar —
  each a prompt template you can rewrite, with {{context}} and {{kb_only}} tokens.
• Built-in previews for every supported format, so a citation opens in place.
• Text extraction and embeddings run locally. Only the passages matching your question
  are sent to the model provider you configure.

Before you start

You need an API key from OpenAI or Anthropic, entered in Settings on first run. The app
is free; you pay the provider for what you use.

Note for existing Windows users

This installer is a per-machine MSI, replacing the old per-user Squirrel installer.
Uninstall any previous build before installing this one. Your data in %AppData%\kbjumper
is left untouched.
