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.

TermLink turns your iPhone into a compact SSH companion for AI coding, server checks, and remote file handoff. Connect to your own SSH host, generate a key pair, copy the public key, and keep the setup steps close to the terminal. Upload screenshots or photos over SCP, then pass the remote path to Codex, Claude Code, or another AI coding workflow without retyping it. The local workspace stays inside the iOS app sandbox. Built-in commands cover file navigation, JSON formatting, Base64 encode/decode, and JavaScriptCore-backed Node-compatible snippets for safe learning and small experiments. Key features: - SSH profile setup with key generation - Remote shell access from iPhone - SCP image upload and remote path handoff - Snippets for frequent SSH commands and AI prompts - Sandboxed local files and bundled command shims - JSON formatter, Base64 tools, and JavaScriptCore snippets - Japanese IME support and app language switching - Adjustable terminal font size - Optional Pro themes, multiple tabs, multiple SSH profiles, multiple snippets, and remote path insertion TermLink is built as an SSH companion, a command-line learning tool, and an AI coding handoff surface. It is not a native package manager, an external code store, or a way to run downloaded native executables after review. Japanese: TermLink は、iPhone から SSH ホストや AI コーディング環境へつなぐための端末ワークスペースです。SSH 接続、SCP 画像アップロード、Codex / Claude Code 向けのリモートパス連携、サンドボックス内ファイル操作、JSON 整形、Base64 変換、スニペット、Pro テーマなどを利用できます。アプリ外のコードをダウンロードして実行するネイティブパッケージマネージャーではありません。

Verdict
The clearest difference is in-app purchases: OpenCone at none against TermLink's 1. TermLink's advantage is update cadence (every 5 days vs every 4 months). On price, ads, device support and iOS requirement there is nothing between them.
