Any iOS 26 users? Light Deep Research + Export .PDF To Proton Drive + New APIs
Post Intention: Hello iOS 26 users + anyone else trying to advance Lumo through their own capacity. My way of being productive and putting good out into the world by trying to advance an AI chatbot that I see massive untapped potential in, and my goal is to get it the top 5 AI assistants section of the Apple App Store. This is a showcase of iOS 26 capabilities and no disrespect is meant to other OS's/platforms. The backend of the OS allowed me to ironically pursue my goal with my newly purchased iPhone Air. Ideally, this proves the concept and paves the way for other platforms. This is a severely stripped down version of file sent over to Support.
Breakdown: Initial theories I had (i.e: token optimization + UI limitations mitigated via output as file) was shown to be factual and I capitalized on it. This post will display snippets from the .PDF I created and it took days with absolutely NO significant AI interference. AI used for backend technical information & learning purposes. Anyone serious who wants to see a redacted report can feel free to PM me. Backend iOS 26 allows for a native and secure experience with exporting to Proton Drive. An expansive 3,000 (time constraints, could have made it to 4,000) words. PDF was created in Proton Docs and finally handed off to support a few hours ago. I proposed a “Deep Research Mode + Generate PDF + Export To Proton Drive. The mode is hard-capped at 3,500 words though it was highly inferred using a reference device (iPhone Air) and precise output with UI elements/artifacts is still to be determined. Editable .docx did not work out for a multitude of reasons and was the original file format of interest. Note: DR+G.PDF is a “one-time” mode. Launch, fill out prompts, toggle switches, input primary prompt, report generated, export to Proton Drive, done.
iOS 26 APIs (EXPORT, PDF UI PRESERVATION ETC):
✔️£) Proton Drive: Already a “FileProvider”- iOS already recognizes it as a destination. (FileProvider + .fileExporter())=Native iOS Share Sheet = Direct Export to Proton Drive as .PDF
✔️£) Document Generation Framework: Perfect preservation of the .PDF while maintaining the UI elements/artifacts of the document with a secure handoff because of Apple sandboxing rules. Tables, code boxes with syntax, bolded headers with emojis, etc.
✔️£) “BGContinuedProcessingTask“: Deep research running for 3-4 minutes? Guess what, you can leave and come back without killing the task!
PRE-REQUISITES FOR EXPORT:
✔️£) Proton Drive App Installed: On iOS 26 device while remaining logged in. User must be notified to login to Proton Drive’s app or potentially select other Proton apps.
✔️£) iOS 26: iOS 26 or later must be installed.
✔️£) Internet: Internet connectivity is required.
DEEP-RESEARCH DESCRIPTION: Deep Research is a new mode/tab or Enhanced Projects Mode implementation that outputs a .pdf file that is ideally directly uploaded to ProtonDrive for ecosystem integration. Deep Research Mode outputs a significant amount of characters and does advanced researching, data pulling, etc to output an almost “guide-like” or “medical-research grade paper like.
SEVERELY STRIPPED PREVIEW OF METHODS:
£) Recursive search loops to output expansive, multi-source information and increase output volume and fidelity.
£) User Interlaced Data (RAG) Mode Failsafes (User Prompts):
✔️£) Methodology Toggle: The methodology toggle gives user control to prioritize uploaded files/URLs as the primary source of data to function as a “control” or point of reference. The alternative toggle prioritizes autonomous AI data gathering. This toggle can provide two very distinct outputs.
✔️£) Scope Failsafe (Low Data Failsafe) Box: Scope failsafe allows user-inputted information the primary input doesn’t account for. Ex: Main input is “Give me a guide on how to use Proton Services.” Scope Failsafe Box: “Proton Mail settings, how to best utilize the advanced model of Lumo through user prompting. Encrypted Proton video chat iOS app.” Model recognizes secondary points to deep dive into. This prevents failure of the mode/difficulty with outputting.
✔️£) Qualifiers Input Box: Mode research direction and anti-redundancy. “I already know about Proton Pass” or “Try to dive a little deeper on the lesser known E2E encrypted Proton video chat”. This acts as a ”fine-tuner of data.”
PARTIALLY RELATED CONTEXT INJECTION FOR BOTH STANDARD AND DEEP RESEARCH QUERIES/STANDARD CHAT PROMPTING BOTTLENECK MITIGATION: The output fidelity is further enhanced by “data interlacing via user inputted data”.
💎 £) TRI-MECHANISM FIX FOR GENERALIZED PROMPTING BOTTLENECK
✔️£) URLs: Text-dominant URLs. Feature exists.
✔️£) File Uploads: Supported file types. Feature exists.
✔️£) Web-Search: Web-Search past April 2024 cutoff. Feature exists.
SIGN OFF: Well, that is the stripped version of the .PDF. It took me a few days to make the actual file which is much more text heavy. I tried to format this as easy as possible. I’d like to remind everyone that if you aren’t on iOS 26, theirs nothing wrong with that and maybe the bottleneck fix can help you whichever side of the fence you stand on. I also have a user written guide in this subreddit which helps clarify the whole “prompting” issue and delivers a temporary mitigation to any potential existing problems. For my fellow iOS 26 users and to the devs, a few new tools came in again, ironically as I decided to look into a ”generated file” format. I have a large desire to help other users and would be honored if you came to me in need of assistance. This was a stripped down version of the .pdf recently sent through the proper channels. I really hope my proposed “light-to-moderate Deep Research &’Generate .PDF” for exporting to Proton Drive get’s picked up one day. If anyone needs more backend information, I can get hard at work! Stay safe and blessed!
