MITHRIL is a private AI assistant that runs on your iPhone and iPad. Your conversations are processed and saved on your device, or on your own Mac if you pair one. No account, no cloud, no tracking. TWO KINDS OF MODELS • Apple's on-device model, built into iOS 26 on devices with Apple Intelligence. Nothing to download. • Open models from Hugging Face in GGUF format, from companies like Alibaba, Google, Meta, Microsoft, Mistral, DeepSeek and Liquid AI. Browse by company, see whether a model fits your device's memory before you download it, and switch any time. AN ASSISTANT THAT CAN DO THINGS It knows today's date, the time and your city from your device, and asks before it acts. Texts and emails open as drafts for you to review and send. Choose which abilities it can use: • Reminders and calendar events • Texts, email and phone calls • Look up your contacts • Directions and places nearby • Run your Shortcuts • Web search: Wikipedia, DuckDuckGo, or Brave with your own key • Search your own documents • Today's date and exact math PHOTOS, YOUR PHONE AND YOUR MAC • Ask about a photo: attach one, take one or paste a screenshot, and models that read images answer on the device. • Search my phone: ask about the text in your photos, screenshots and the folders you pick, indexed on the device. • Use your Mac: pair your own Apple silicon Mac and chat with the bigger models on it over your Wi-Fi, encrypted between your devices. • Run your coding agents or a terminal on your Mac from here. PRIVACY YOU CAN SEE The Privacy map shows what runs on your device, what goes online, and exactly what is sent. A web search sends only the search words, never your conversation, and your location is only turned into a city name. A live list shows every network request MITHRIL makes. VOICE Dictate with Apple's speech recognition, or download NVIDIA Parakeet for more accurate on-device transcription. Hear answers in natural voices generated on the device. The floating assistant stays with you in Picture in Picture while you use other apps. FOR THE CURIOUS Tap the speed line under an answer for a live engine dashboard: tokens per second, time to first token, context use, cache hits and memory. REQUIREMENTS iOS 26. Apple's on-device model needs a device with Apple Intelligence. Open models run on any supported iPhone or iPad. Larger models need more memory, and MITHRIL shows what fits before you download. Models are made by their publishers and downloaded from Hugging Face. MITHRIL doesn't train or host models.

Verdict
The clearest difference is rating: Local LLM at 4.5 against Vector Space AI's 4.0. Local LLM also leads on ratings volume (16 vs 1). Vector Space AI's advantage is review sentiment (100% vs 89%) and iOS requirement (18.0 vs 26.0). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Local LLM holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Local LLM has 16 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Vector Space AI's written reviews are positive against 89% of Local LLM's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 4 days. The most recent releases landed on October 30, 2026 and November 5, 2026 respectively.
