LocalEngine vs Boreal PDF

LocalEngine runs open-source AI language models entirely on your iPhone and iPad. Everything happens on-device: your prompts, conversations, and images never leave your device and are never sent to any server. Built in pure Swift with SwiftUI, LocalEngine runs models through a Metal-accelerated llama.cpp engine, so you get fast, low-latency AI completely offline — no account, no sign-in, no cloud. WHAT YOU CAN DO • Chat — Hold multi-turn conversations with a local model. Replies stream token-by-token in real time. Start a new chat or stop a response at any time. • See images — Turn on vision in Settings, attach photos to your message, and ask about them. Images are understood entirely on-device by a vision-capable model. • Download models — Browse a curated catalog of open models and download the one that fits your device. Downloads run as resumable background jobs with live progress, and the screen can stay awake while a large model downloads. • Tune generation — Adjust the response length (max tokens) and the temperature to shape how the model replies. • Unlock larger models — LocalEngine is free to use with starter models. A one-time Pro upgrade unlocks larger catalog downloads on iPhone and iPad. CURATED MODELS LocalEngine is ready to chat out of the box with a small, fast default model, and its catalog includes compact vision-language models you can grow into: • Qwen3.5 — 0.8B and 2B free, with 4B available through Pro • Gemma 4 — E2B free, with E4B available through Pro Smaller models are quick and light on storage; larger Pro models are more capable on newer devices. Each vision model pairs with a multimodal projector so it can understand images — all on-device. PRIVATE BY DESIGN • 100% on-device inference — no cloud, no telemetry, no analytics. • No account and no sign-in required. • Runs fully offline once a model is downloaded. • Built to App Store privacy and security standards. REQUIREMENTS • iOS / iPadOS 17.0 or later • A recent iPhone or iPad is recommended, especially for the larger models • Free storage space for the models you choose to download LocalEngine puts the power of modern AI — text and vision — in your pocket, without giving up your privacy.

Boreal PDF helps you turn paper forms, receipts, certificates, contracts, and application documents into cleaner PDFs from iPhone. Start with a camera scan, selected photos, or an imported PDF. Boreal PDF keeps the workflow focused on the practical steps before submission: straighten the page, improve text readability, fill in missing marks, reduce file size, and export a PDF you can review before sending. Key tools: - Scan paper documents or import photos and PDFs. - Auto-crop, rotate, retake, reorder, merge, or split pages. - Add dates, names, signatures, freehand ink, and stamp-style marks. - Compress PDFs toward common upload limits. - Run OCR for printed Japanese and English text. - Preview the final PDF, then save, share, or print it from iOS. Boreal PDF is local-first by design. The companion website does not provide cloud document storage, account sync, or server-side PDF processing. OCR works best on clear printed text; handwriting, glare, low light, and heavy skew can reduce accuracy, so always review important documents before submitting them. Boreal PDF is free to start with 5 documents per day. Within that allowance, form marks, compression, OCR, searchable PDF, and watermarked export stay in the workflow. Pro removes the daily document limit and unlocks watermark-free final export. A 24-hour Pro Pass is available for short-term access, alongside monthly and yearly Pro subscriptions. Current prices, trial availability, renewal terms, and regional availability are shown on the App Store.
