Xpense AI helps you turn your receipts into structured expenses — using the AI model you choose. Use a local LLM via LM Studio for fully offline processing, or connect your own API key (OpenAI, Grok, Open Router - more models soon) for cloud-based extraction. Xpense AI itself doesn’t upload or store any receipt data. If you use an online AI provider, your invoice images will be sent only to the service you configured, using your credentials. Features • Scan or import receipts, invoices, PDFs, screenshots • AI extraction using your chosen model (local or online) • Supports totals, VAT, currencies, dates, merchants, line items • Optional: load your company policy for compliance checks • Organize expenses by trip and date • Customize and export clean reports • No accounts, no cloud storage — data stays with you

Verdict
The clearest difference is in-app purchases: TDK at none against X's 1. TDK also leads on iOS requirement (15.0 vs 17.0). On price, update cadence, ads and device support there is nothing between them.
