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.

Manage your GitHub website with SiteAgent. Describe a change, inspect the proposed edits, preview your site, and commit when you are ready.

Choose a supported cloud AI provider using your own account or API key, or download a compatible on-device model on supported hardware.

SiteAgent Super unlocks additional sites and providers and removes the app session limit. Monthly, yearly, and lifetime purchases are available; Apple shows current prices and any eligible offers before purchase.
