Most notes apps are just storage. You write something, it disappears into a list, and you never think about it again. Wisen works differently — it reads what you write and brings the right ideas back at the right moment. Echo finds threads across your notes and turns them into questions worth sitting with. Not generic prompts — specific questions built from what you actually wrote. Sometimes it connects two notes from different weeks and surfaces a pattern you hadn't noticed. Each session feels less like a review and more like continuing a conversation you forgot you started. Pulse delivers a daily brief built entirely from your recent notes. What you've been thinking about, what's still unresolved, what questions are worth returning to. It also drafts LinkedIn posts, emails, and more directly from your notes — your voice, your ideas, not a generic AI output. WisenChat lets you ask anything about your notes. What did you write about this topic last month? What's still unresolved? What decisions are you avoiding? It answers from your actual notes with citations — so you always know where the insight came from. Knowledge Map shows how your notes connect visually. Tap a link to open a cross-note Echo session between two related ideas. The map grows richer the more you write. Spaced repetition tracks which ideas you've genuinely learned and which ones need revisiting — at the block level, using a modified SM-2 algorithm. Mastered content is excluded automatically so you're never drilling what you already know. Everything is encrypted with AES-256-GCM before leaving your phone. AI features use OpenAI — only the content you actively engage with is ever processed, and none of your notes are used to train their models. Import PDFs, scan handwritten notes, drop in images and voice recordings. Works in 16 languages. No account required to start. The longer you use Wisen, the more useful it becomes. Your notes compound into real knowledge instead of disappearing.

About

Phantasm

Features
Read full description

Phantasm is a private AI chat client for the backend you already run. Point it at your own server: Ollama, vLLM, llama.cpp, or any OpenAI-compatible endpoint and chat with your own models over your own network. No account, no middleman, no data collection. YOUR SERVER, YOUR RULES • Connect with just a URL and a token — works against a bare Ollama out of the box • Add the open-source Phantasm orchestrator to unlock web search, image generation, and research modes • Multiple backend profiles for home network, VPN, or tunnel setups • Your token lives in the iOS Keychain; conversations are stored only on your phone A REAL CHAT EXPERIENCE • Fast streaming responses with markdown, syntax-highlighted code blocks with copy, and charts • Attach photos and files — vision models can see your images • Generated images appear inline; save or share them • Dictate messages with on-device transcription and have replies read aloud • Long generations survive backgrounding and pick up where they left off • Ask Phantasm from Siri and Shortcuts TOOLS ON YOUR TERMS • Per-chat toggles for web access and image generation • Optional device tools — location, calendar, Apple Health — are off by default and only shared with your own backend when you enable them • See the model's reasoning when a thinking model is selected PRIVATE BY DESIGN Phantasm operates no servers and collects no data. The app talks exclusively to the backend you configure — nothing else. What you say to your AI is between you and your hardware. Phantasm requires an OpenAI-compatible server that you provide (for example, Ollama running on your own machine). Feature availability depends on your backend's capabilities.
