Clean Text helps you edit, correct, and organize text quickly and reliably, making everyday writing tasks easier. It’s designed for anyone who works with text: writers, students, developers, marketers, and anyone who copies and pastes content between different apps. From fixing formatting issues to preparing clean, readable text for emails, documents, websites, and social posts, Clean Text keeps your work consistent and well organized. Complete Text Cleanup Clean Text solves the most common formatting problems that appear when copying text from emails, PDFs, web pages, or chat messages. Remove empty lines, extra spaces, tabs, unwanted characters, smart quotes, or line breaks in seconds. A rich set of cleanup tools lets you standardize content with a single tap, making even the messiest text immediately usable. Editing with Apple Writing Tools Clean Text supports Apple Writing Tools, integrating them alongside all the classic text cleaning and formatting features. You can use them to correct, rewrite, summarize, and improve your text directly in the app. AI-based features are always optional and are only activated when you choose to use them. Powerful Find and Replace Real-time search instantly highlights all matches in the text, making it easy to locate words, phrases, or patterns even in long documents. Options like Case Sensitive and Whole Word give you precise control, while the live preview makes replacements safe and reliable. Recent Texts and Smart History Quickly access recently copied texts and reuse previously applied transformations to speed up repetitive workflows. Seamless Cross-Device Integration Thanks to iCloud, you can start working on iPhone or iPad and instantly find your text on your other devices. Recent changes are always available, with no manual steps required.

About

Sigmy

Features
Read full description

Sigmy is a fully on-device AI assistant. The language model, document search, and every piece of private text stay on your iPhone or iPad. No cloud. No account. No tracking. No training on your data. Ever. WHY SIGMY IS DIFFERENT • Runs a Google Gemma model locally on your device — no API keys, no subscriptions to external AI services, and no network round-trips that can leak your content. • Works offline, on a plane, in a tunnel, or in a sensitive workplace where cloud AI is banned. • Your documents, chats, and questions never leave your device. We cannot read them and neither can anyone else. WHAT YOU CAN DO • Ask questions about your PDFs, Word docs, text files, Markdown, and scanned images — every answer cites a tappable source passage. • Import documents by tapping +, scanning with the camera, capturing text from photos, pasting images, or sharing from any other app. • Compare two or more documents side-by-side — "what's different between these contracts?", "which proposal has better terms?". • See comparison answers as clean tables when the model formats them that way. • Tap suggested follow-up questions after each answer to dig deeper with one tap. • Extract events from any document straight to your Calendar — meeting dates, deadlines, travel itineraries. • Hands-free mode: have Sigmy read answers aloud in your choice of voice — fully on-device. • Dictate questions by voice and export chats as PDF, Markdown, plain text, RTF, or email. • Search your chat history to find past conversations instantly. • Full-text search across every document you've imported, with semantic ranking that understands what you meant. • Quick-prompt templates for executive summaries, action items, study outlines, and timelines. PRIVACY BY DESIGN • Optional Face ID / Touch ID unlock for the whole app. • Optional AES-GCM encryption of the document index at rest, sealed whenever you background the app. • Privacy manifest declares every iOS API we touch and why. • PII detection warns you before indexing credit card numbers or other sensitive identifiers. FREE TRIAL — 7 DAYS OF EVERYTHING Every new install gets a 7-day free trial with full Pro features: unlimited documents, extended memory window, and all advanced tools. No credit card required. SIGMY PRO After the trial, Sigmy Pro unlocks: • Unlimited document imports and queries • Extended memory window for long files • All advanced tools and future Pro features at no extra cost THREE WAYS TO SUBSCRIBE • Pro Monthly — $5.99/month after a 7-day free trial • Pro Yearly — $39.99/year after a 14-day free trial (saves ~50% vs monthly) • Lifetime Pro — one-time $79.99, permanent access, no renewals SUPPORTED DOCUMENT TYPES PDF, Word (.docx), plain text (.txt), Markdown (.md), Rich Text (.rtf), HTML, CSV, and images containing text (via on-device OCR). DEVICE REQUIREMENTS iPhone or iPad with sufficient RAM for on-device AI. Sigmy adapts memory settings automatically to your device. The language model (~3.4 GB) is included in the app — no separate download after install. Works fully offline once installed. — SUBSCRIPTION TERMS Sigmy Pro is an auto-renewable subscription. • Pro Monthly: $5.99 per month after a 7-day free trial. • Pro Yearly: $39.99 per year after a 14-day free trial. • Lifetime Pro: one-time $79.99 non-renewing purchase. Payment will be charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period.
