GAMMA AR: Augmented Reality for Construction Site Management GAMMA AR is an application designed for monitoring construction sites. It utilizes augmented reality technology to overlay 3D Building Information Models (BIM) on construction sites using smartphones or tablets. With GAMMA AR, site managers, facility managers, craftsmen, and other stakeholders involved in the construction process can walk through the site and compare real-world conditions with the planning information contained in 3D BIM models. GAMMA AR enables the visualization of 3D BIM models before and during the construction process, thereby fostering a better understanding of the planning, preventing errors, and reducing construction costs. This enables site managers and planners from various disciplines (HLS, architecture, etc.) to collaborate on the construction site using the BIM model, preventing collisions and resolving ambiguities before they lead to errors. Additionally, GAMMA AR allows for the direct detection of errors within the BIM model, enabling adjustments to be made during the planning phase, preventing errors, and ensuring comprehensive monitoring of construction progress. Is GAMMA AR for you? GAMMA AR allows you to connect various software systems such as Autodesk, Procore, and BIMCollab. Construction site managers benefit from GAMMA AR by avoiding errors and eliminating the need to interpret 2D plans. Facility managers can report errors or make adjustments directly in the BIM model via GAMMA AR and transmit this information to other stakeholders involved in the construction process. GAMMA AR is an easy-to-use, intuitive tool that can be applied directly without requiring any training that could increase the cost of implementation. For construction companies, GAMMA AR offers significant benefits: entire departments can be relieved of the burden of communicating via 2D plans, which is no longer necessary. GAMMA AR establishes digital communication channels between the construction site and the office. Using BIM360 or Autodesk Construction Cloud (ACC)? Simply sign in with your Autodesk account, import your IFC, REVIT, and NAVISWORKS models into GAMMA AR, and synchronize your issues with BIM360, ACC, Procore, or BIMCollab. Summary Avoid Errors: Plans on-site are cumbersome and prone to errors! For many tasks, it is faster and safer to review the plans directly on a tablet and compare them with real-world conditions. By working digitally on tablets and smartphones, the reliance on paper plans is significantly reduced, thereby lowering the risk of obsolete information and redundancies. Sync Models and Notes with Your Office: With GAMMA AR, you can send issues directly from the construction site to the office. Each comment is directly linked to a building element or room during site inspections. With this location reference, new information is immediately integrated into the building model. This simplifies documentation and improves communication, as comments are clearly and unambiguously conveyed.

Saelyx is an assistant that lives with you across every device, carrying your memory, your knowledge and your files. This app is one of its doors. It's in early access, and it's open: download the app and sign in with your email. SEES, HEARS AND ACTS AT ONCE Most assistants do one thing at a time: they read, or they listen, or they look. Saelyx does all three at once and reasons about them together. Show it your screen while you talk to it and hold something up to the camera, and it understands the three as a single situation. · Screen · reads what you have in front of you while you work. · Camera · show it something and it understands it straight away. Includes up to 10 camera photos a day; each new photo uses 2 units of your cycle. · Voice · listens to you continuously, with nothing to press. REAL CONVERSATION It answers in under a second, and you can cut in mid-sentence, the way you would with a person. No waiting for it to finish before you change the subject. IT REMEMBERS YOU, AND YOU CAN READ WHAT IT REMEMBERS What you tell it today is still there tomorrow: names, context, preferences. Out of that it distils a portrait of who you are, which you can open, edit, regenerate and delete. It is plain text, not a black box. YOUR KNOWLEDGE, INSIDE IT Upload your documents and they become its own: contracts, manuals, notes, whatever you have. Ask across all of them at once, by voice too, and it searches inside them, not by filename. IN YOUR MEETINGS Meeting Mode listens, follows the thread and keeps what you need in view while you're still talking. Not a summary at the end: help during. Afterwards you keep the summary and the transcript, on every one of your devices. YOUR DAY, IF YOU LET IT With your permission it reads this iPhone's calendar to tell you what meetings you have when you ask. It only reads: it never creates or changes events, and it does not store the contents of your calendar. IT REMINDS YOU Ask it to remind you of something and it will. Your reminders sort themselves, soonest first. DICTATION IN ANY APP Its own keyboard so you can dictate wherever you type, and a history of what you dictated in case something goes missing. ON YOUR WRIST The Apple Watch app lets you talk to Saelyx without taking your phone out, and it replies out loud. BUILT FOR iPad Not the iPhone app stretched: on iPad it has its own sidebar and detail pane. THE SAME ACCOUNT, EVERYWHERE iPhone, iPad, Apple Watch, Mac and the browser. What's inside — your memory, your knowledge, your files, your meetings — is the same from any of them. This app is a door, not a separate copy. YOURS, AND PORTABLE Make a backup with your memories, your notes and your files, keep it yourself and load it back whenever you want. Export your profile and your sessions. Two-factor verification with your authenticator app, control over the sessions and devices you have open, and full deletion of your account. BUILT AROUND YOU Tune how it answers you and how long it thinks before replying. And teach it new skills, which it reuses from then on. PRIVACY, SPECIFICALLY · Your voice and whatever you show it are processed on the spot, and are not stored to train models. · Your data is stored encrypted on servers in Europe, tied to your account alone. · No advertising. We do not sell your data, and we do not share it with third parties to profile you. · Before storing anything sensitive we ask you in writing, explaining what, where, for how long and how to delete it. And you can withdraw it whenever you want. · Before doing something that cannot be undone, Saelyx asks you to confirm. Saelyx grows every week: what it does today isn't what it will do next month. Saelyx talks with you using artificial intelligence. Answers can contain mistakes: check them before making decisions that matter. An internet connection is needed in order to talk.

Verdict
The clearest difference is in-app purchases: GAMMA AR at none against Saelyx's 6. Saelyx's advantage is update cadence (every 3 days vs every 2 weeks). On price, ads, device support and iOS requirement there is nothing between them.
