Our apps
Privacy-first iPhone apps where all AI runs on-device. No servers, no accounts, no analytics.
Free to start, with every feature fully functional. A single one-time unlock opens unlimited use. No subscription, ever.
PromptSiege
Prompt injection, hands-on.
A hands-on dojo for AI security. Instead of reading about prompt injection, you actually do it. Against a real language model running entirely on your iPhone. Breach the model across 10 escalating challenges, then map every exploit to OWASP LLM Top 10 and MITRE ATLAS defenses.
Features
- 10 escalating injection challenges, from first leak to the Dojo Master
- Real LLM inference on-device. Apple Intelligence or an optional open-weights model
- Defence debriefs mapped to OWASP LLM Top 10 and MITRE ATLAS
- Training mode plus an on-device judge that grades every attempt
- No account, no cloud, no analytics. Your prompts never leave your phone
Privacy
- All inference runs locally via Apple Intelligence or an optional open-weights model
- No account, no cloud, no analytics
- Optional one-time ~2 GB model download, only with your consent
Offline AI Notebook
Your private AI notebook.
Import PDFs, plain text, and Markdown. Scanned PDFs included, via on-device OCR. Record or import audio and let the built-in on-device speech model transcribe it, even with your phone locked. Ask questions and get streamed answers with citations to the exact page and passage, or generate quizzes from your own sources.
Features
- Import PDFs, text, and Markdown; scanned PDFs read with on-device OCR
- Record or import audio, transcribed by an on-device open speech model. Even with the phone locked
- Answers cite the exact page and passage; no hallucinated sources
- Five-question quizzes generated from your sources, graded in pure Swift
- Streaks and locally-scheduled daily reminders
- Works in airplane mode. No servers, no accounts, no analytics
Privacy
- All AI runs on-device: Apple Intelligence or a built-in open model, on-device embeddings, on-device speech transcription
- The only permission the app ever requests is the microphone
- One-time model downloads (~200 MB – 2.2 GB), each only with explicit consent
Offline Receipts
Receipts to spreadsheet, privately.
Snap a photo of a receipt and Offline Receipts extracts the vendor, date, total, and tax, entirely on your iPhone. No accounts, no cloud, no uploads. Just clean data you can edit and export to CSV.
Features
- Camera or photo library: one tap and the receipt is read with on-device OCR
- Smart parsing finds the grand total (not the subtotal) and the tax amount (not the percentage)
- Every field is editable, with the original scan and raw text attached
- Export your history as CSV via the share sheet, and re-import it on a new iPhone
- Zero network activity: works fully offline
Privacy
- Text recognition runs locally via Apple's Vision framework
- Receipts are stored on-device only; there are no servers to send them to
- CSV export goes through the iOS share sheet, so we never see it
