CHAT WITH YOUR WORKSPACE'S MODELS • Pick any model your workspace offers, or leave it on Auto and let Langdock choose • Set how hard a model thinks: higher levels take longer for better answers • Watch answers appear as they are written, with tables, code, math, charts and images • Regenerate an answer with a different model • Attach photos, take a picture, add files or files from your integrations, or paste, and ask about them • Files the AI creates arrive as cards you can open, preview and share WEB SEARCH AND DEEP RESEARCH • Search the web in a chat and see numbered sources next to the answer • Open the sources sheet to check where a claim comes from • Start a deep research run and read the finished report with its sources AGENTS, PROJECTS AND PROMPTS • Find your team's agents, pin your favorites and start a chat with one • Type @ in the message box to mention agents, integrations, knowledge folders and saved prompts • Keep instructions, files and chats together in a project • Pin, rename, search and organize your chat history, and switch between workspaces INTEGRATIONS, WITH YOU IN CONTROL • Agents can act in your connected tools, such as your CRM or your mail • When an action needs your OK, Langdock shows what it is about to do and waits for you to Confirm or Deny • Choose which connection to use, or reauthorize or add one without leaving the chat VOICE • Dictate a message with your voice on iPhone or Apple Watch ALWAYS WITHIN REACH • Live Activities and Dynamic Island: follow a long answer from the Lock Screen, see its steps, and get notified when it is done or needs you • Widgets: ask from the Home Screen, or add New chat, Dictate and Latest chat to your Lock Screen • Control Center and Action button: start a new chat or dictate with one tap • Siri, Shortcuts and Spotlight: "Ask Langdock", start a new chat, search your chats or open an agent • Quick actions: press and hold the app icon for New chat, Dictate, Camera or Search • Share extension: send text, web links, images and PDFs from any app straight into a chat (up to five files, 25 MB each) APPLE WATCH • Ask with your voice, read the answer on your wrist, reply with a quick tap and pick up recent chats • Add Langdock to your watch face or Smart Stack for one-tap access • Your watch signs in through your iPhone, so there is nothing to set up MADE FOR iOS 26 • Native SwiftUI design with Liquid Glass, light and dark mode, and Dynamic Type • iPhone and iPad, with the iPad in every orientation • Available in English and German • No ads, and no third-party tracking in the app Langdock requires iOS 26 or later and a Langdock workspace account.

Verdict

The call

The clearest difference is review sentiment: Privacy AI at 92% against Langdock's 32%. Privacy AI also leads on ratings volume (21 vs 1) and iOS requirement (18.0 vs 26.0). Langdock's advantage is in-app purchases (none vs 3) and rating (5.0 vs 4.8). On price, update cadence, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Langdock holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Privacy AI has 21 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 92% of Privacy AI's written reviews are positive against 32% of Langdock's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Privacy AI ships an update weekly, Langdock every 2 weeks. Both last shipped on November 8, 2026.
