Local LLM Server Pro vs Hex

Turn Apple Intelligence into a local API for your scripts and apps. Local LLM Server Pro exposes Apple's on-device language model through selected OpenAI and Ollama-compatible endpoints. Inference stays on your device. PRO: A ONE-TIME PURCHASE No ads and no daily generation request quota. Pro does not expand Apple's model context window or guarantee background service. The free version is ad-supported and allows 100 generation requests per day. START WITH ONE RESPONSE Enable Apple Intelligence and wait for the model to be ready. Start the server, open the in-app playground, and ask a short question. Then use the curl, Python or JavaScript examples in Server Information to connect your client. A step-by-step setup guide is available from the support link. SUPPORTED WORKFLOWS • OpenAI Chat Completions with a custom /v1 base URL, streaming, structured output and tool-call responses. • Selected Ollama chat, generate and model-list endpoints. • Text embeddings using Apple's contextual embedding provider. • Same-device localhost access, or local-network access with an optional API key. • Server logs, request statistics and Shortcuts for server controls. KNOW THE LIMITS This app uses Apple's supported on-device model. It does not import GGUF or Hugging Face models, download arbitrary Ollama models, or provide OpenAI's Responses API. Use model IDs returned by the server, such as base. Compatibility depends on the endpoints your client uses. Requests can contain up to 1 MiB of JSON. This HTTP byte limit is separate from the model's token context. Shorten large conversations or tool definitions; use max_tokens to bound replies. KEEP THE SERVER VISIBLE Keep the app in the foreground while serving. On iPad, use Split View with your client alongside it. Requests may pause when the app is backgrounded or the screen locks. The optional background reminder is advisory, not suspension detection. REQUIREMENTS Apple Intelligence-capable hardware with iOS/iPadOS 26 or later, or macOS 26 or later on a compatible Apple silicon Mac. Apple Intelligence must be enabled, supported in your language and region, and its on-device model ready. Setup may require a model download.

Hex is a developer toolkit for iPhone and iPad: 21 small utilities for the jobs that interrupt real work, like decoding a token, pretty-printing a payload, testing a pattern or checking a file hash. Everything runs on your device. ENCODE • Base64: encode text, or decode standard, URL-safe (base64url), line-wrapped (MIME) and unpadded input. Bytes that aren't UTF-8 text are shown as a hex dump. • URL Encode: percent-encode a value so & = ? / # + : @ are escaped, or decode it (+ reads as a space). Malformed escapes are flagged. • HTML Entities: encode ampersands, angle brackets and quotes, or decode every HTML 4 named entity (nbsp, copy, mdash and the rest) plus decimal and hex references. • JWT Decode: header and payload as readable JSON, with claim order kept. • Hash Generator: MD5, SHA-1, SHA-256 and SHA-512 of any text. FORMAT • JSON Formatter: prettify, minify and validate. Your key order, numbers and escapes stay exactly as written, and top-level values like "text" or 42 are accepted. • XML Formatter: indents and validates. Comments, CDATA, processing instructions and the XML declaration are kept, and the output is re-escaped so it stays valid XML. • SQL Formatter: puts SELECT, FROM, WHERE, JOIN, GROUP BY and ORDER BY clauses on their own lines and uppercases keywords. Strings, quoted names and -- or /* */ comments pass through unchanged. • Markdown Preview: headings, bullet and numbered lists, block quotes, fenced code blocks and rules, with bold, italic, inline code and links. • HTML Preview: renders your HTML offline. Remote images, scripts, styles and frames are blocked, and links don't navigate away. GENERATE • UUID Generator: version 4 UUIDs, 1 to 100 at a time, upper or lower case. • Lorem Ipsum: words, sentences or paragraphs. • Password Generator: 4 to 128 characters from uppercase, lowercase, digits and symbols, with at least one from each set you pick. The strength meter shows entropy in bits. • Color Converter: HEX (3 or 6 digits), RGB and HSL, each editable with sliders. • Checksum: MD5, SHA-1 and SHA-256 of a file from Files, read in chunks so large files work, and a check against an expected hash. TIME • Unix Timestamp: timestamp to date and back. Seconds, milliseconds and microseconds are recognised. • Cron Parser: standard five-field cron with ranges, lists, steps and month or weekday names, a plain-English description and the next five run times. • Timezone Converter: pick a time and the zone it's in, then see it in any of the listed zones. TEXT • Diff Checker: line-by-line comparison that lines up inserted and deleted lines. • Regex Tester: matches highlighted in your text, a numbered match list, and case-insensitive, multiline and dot-matches-newline options. • Text Inspector: characters, words, lines, sentences, paragraphs and UTF-8 bytes, with a character breakdown. WORKFLOW • Clipboard detection: copy JSON, a JWT, Base64, a URL, XML, HTML, a Unix timestamp, a hex color or SQL, and Hex offers the matching tool with your text already in it. iOS may ask permission before Hex reads the clipboard. • Deep links: hex://json, hex://jwt, hex://base64, hex://cron and the other tools open directly from Shortcuts or other apps. • Copy any result, or export it as a file (.json, .xml, .sql, .txt and more) through the share sheet. WHAT HEX DOESN'T DO • No network tools: no HTTP client, no API testing, no DNS lookups. • JWT Decode reads tokens but does not verify signatures. • Cron Parser doesn't support the L, W or # extensions or a seconds field. • The SQL Formatter changes layout only. It doesn't run or validate queries. • No sync and no history beyond your five most recent tools. PRIVACY Nothing leaves your device. Hex makes no network requests, has no analytics, no tracking and no accounts. Text you paste and files you hash stay on your iPhone or iPad. PRICE A one-time purchase. No subscription, no in-app purchases and no ads. Made by SHYGUY LLC.
