OpenCone turns the documents on your iPhone into answers you can check. Bring your own OpenAI and Pinecone keys: OpenCone reads and splits your files on the phone, stores them in your own Pinecone index, and answers your questions with OpenAI, citing the passage behind each claim. ASK • Answers stream in as they're written, with headings, lists, tables and code. • Claims carry tags such as [S1]. Tap one to read the exact passage, with its file, page and score. • Follow-up questions see your earlier exchanges. • Ask by voice, with Apple's speech recognition. SEARCH ONE INDEX OR ALL OF THEM • Auto reads each question and searches the indexes and namespaces likely to hold the answer, up to five at once. Ask it to compare two and it searches both. • Everything searches every namespace of every index you include. • One index searches the index you pick, in one namespace or in each of them. • Questions are embedded with the model that built each index, so the indexes you already have work as they are. • Optional reranking with Pinecone's hosted rerankers. YOUR DOCUMENTS • Import PDFs, plain text, Markdown, RTF, HTML, JSON, XML, CSV, code and images. Text in images is recognized on the phone. • Choose the index and namespace for each upload, follow its progress, and see how long each step took: read, split, embed and store. • Create and delete indexes and namespaces, with the cloud, region and metric you choose. ANSWER SETTINGS THAT FOLLOW THE MODEL • Choose from the current GPT models, or enter any model ID your key can use. • Reasoning effort, answer length up to the model's maximum, detail, service tier, web search and code interpreter, each offered where the model supports it. • Add your own instructions to every answer. SEE EVERY API CALL • Settings lists every OpenAI and Pinecone endpoint OpenCone calls: what it's for, the settings that shape it, and how this session's requests went. PRIVATE BY DESIGN • Your keys stay in the iPhone's Keychain. • No account, no analytics, no ads, and no server in between: requests go straight from your iPhone to OpenAI and Pinecone. • Answers are requested with storage off, so OpenAI keeps no conversation between questions. • One reset removes your keys, your settings and what OpenCone learned about your indexes. OpenCone works with your own OpenAI API key and your own Pinecone API key and project. OpenAI and Pinecone bill their usage to your accounts.

READ BEFORE PURCHASE: Installed fonts are available in apps that support Apple’s user-installed font system. Apps that provide only their own built-in font list may not display them. Ligatures depend on each app’s text-rendering settings and cannot be forced if the app does not support or enable them. Nerd Fonts Installer includes 18 Nerd Font families and 118 bundled faces. All font files, catalog data, metadata, and licenses are included with the app; no font downloads or account are required. AVAILABLE FONTS • 0xProto Nerd Font • AnnotationM Nerd Font • AtkynsonMono Nerd Font (based on Atkinson Hyperlegible Mono) • ComicShannsMono Nerd Font • DroidSansM Nerd Font • FiraCode Nerd Font • GoMono Nerd Font • Hack Nerd Font • Inconsolata LGC Nerd Font • Inconsolata Nerd Font • InconsolataGo Nerd Font • JetBrains Mono Nerd Font • MesloLGM Nerd Font • OpenDyslexic Nerd Font • Terminess Nerd Font • Ubuntu Nerd Font • UbuntuSansMono Nerd Font • VictorMono Nerd Font AtkynsonMono and OpenDyslexic provide accessibility- and readability-oriented options alongside coding and monospace designs. FEATURES • Search the complete bundled font catalog • Preview each actual bundled font with editable specimen text • Switch among every supplied face and preview sizes from 5–42 pt • Install every supplied face in a family together through the iOS Fonts system • See installation status and remove one family or all fonts installed by the app • Browse Unicode characters, Private Use Area icons, encoded and unencoded glyphs, alternates, and ligatures • Search character and glyph maps by character, code point, Unicode name, glyph ID, name, or kind • Inspect Unicode details, glyph mappings, icon sources, categories, and metrics • Copy characters and mapped glyph text • Inspect embedded names, traits, language coverage, OpenType features, variation axes, font tables, file details, counts, and checksums • Read copyright, attribution, incorporated-work notices, and complete bundled license text • Open a prefilled support email containing the app version, device model, and OS version • Native iPhone and iPad interface designed for iOS 26. Core browsing, previews, metadata, licenses, installation, and removal work from bundled resources without a network connection. Here is a non-exhaustive list of apps that user-installed fonts should work with: Code App, a-Shell, Pyto, Blink Shell, Prompt 3, Drafts, Adobe Apps, Tot, Goodnotes, Notability, Pages, Keynote, Numbers, Procreate, Adobe Photoshop, Adobe Premiere, Final Cut Pro, OmniGraffle, Noteful, IceCubes, Aidoku, Moblin, Provenance, Typography Insight, Accordance, iDesign, Clip Studio Paint, Ulysses, Noto, HashPhotos. If an app works with your Adobe Creative Cloud user-installed fonts on iOS, it should work with these (same underlying mechanism) I can verify Textastic and Obsidian do not support user-installed fonts. Textastic documentation clarifies that it's only fonts installed through a profile. Obsidian change log says it does, but no user-installed fonts were in the list of available fonts.
