TooAi is an offline AI toolkit for Android. A local LLM chat, a system-wide AI writer, and four on-device scanning tools — all running on your own phone. No account, no subscription, nothing uploaded to a server. ━━━━━━━━━━━━━━━━━━━━ OFFLINE AI CHAT — RUN YOUR OWN LLM ━━━━━━━━━━━━━━━━━━━━ Import a model file and chat with it entirely on your device. TooAi runs on LiteRT-LM, so small models like Gemma 3 and Qwen2.5 answer straight from your phone's hardware — even in airplane mode. • Import any .task or .litertlm model from your files • Tune max tokens, temperature, Top-K and Top-P per model • Multiple chat sessions, saved locally and searchable • Markdown replies with headings, lists and code blocks • Nothing you type ever leaves the device ━━━━━━━━━━━━━━━━━━━━ AI WRITER — IN EVERY APP YOU TYPE IN ━━━━━━━━━━━━━━━━━━━━ Select text anywhere on your phone — email, chat, notes, browser — tap TooAi in the selection menu, and rewrite it on the spot. • Polish — formal, casual or friendly tone • Summarize — bullet points, short paragraph or concise • Proofread — fix grammar, clarity or wordiness • Write anything — free-form prompt using your selection as context • Tap Replace and the rewritten text drops back into the field • Generate several variants and swipe between them ━━━━━━━━━━━━━━━━━━━━ DOCUMENT SCANNER — SCAN TO PDF ━━━━━━━━━━━━━━━━━━━━ Scan paper documents, receipts and notes with automatic edge detection and cropping. Every scan is saved as a PDF you can share or delete from an in-app list. ━━━━━━━━━━━━━━━━━━━━ QR & BARCODE SCANNER ━━━━━━━━━━━━━━━━━━━━ Scan QR codes and product barcodes, and keep every result in a local history — links, Wi-Fi codes, EAN and UPC barcodes, plain text. Nothing is logged to a server. ━━━━━━━━━━━━━━━━━━━━ TEXT RECOGNITION — IMAGE TO TEXT ━━━━━━━━━━━━━━━━━━━━ Extract text from any photo or screenshot with on-device OCR, then copy it to your clipboard in one tap. Ideal for pulling text out of documents, signs, slides and receipts. Past extractions stay in your history. ━━━━━━━━━━━━━━━━━━━━ BACKGROUND REMOVER — SUBJECT CUTOUT ━━━━━━━━━━━━━━━━━━━━ Pick a photo, tap once, and TooAi separates the subject from the background. Save the cutout straight to your gallery — no editing skills, no watermark, no export limits. ━━━━━━━━━━━━━━━━━━━━ BUILT FOR PRIVACY ━━━━━━━━━━━━━━━━━━━━ • Every AI feature runs on your device — text and images are processed locally • No sign-up, no login, no user account • No ads, no analytics SDKs, no tracking • No in-app purchases or subscriptions • Requests no camera and no storage permission — scanning is handled by the system camera and Android's photo picker • Your chats, scans and history live in a local database you can wipe by clearing app data ━━━━━━━━━━━━━━━━━━━━ GOOD TO KNOW ━━━━━━━━━━━━━━━━━━━━ • Requires Android 8.0 or newer • Offline AI chat and the AI Writer require Android 12 or newer, plus a model file you supply • Language models are not bundled — you import your own, so the download size stays small • Bigger models need more RAM; 1B–2B parameter models suit most phones • Scanning, OCR and cutout features use Google Play Services on-device modules, which download once and then work offline • On some Samsung devices the text-selection entry must be enabled under Settings, and appears after TooAi has been opened once ━━━━━━━━━━━━━━━━━━━━ Offline AI assistant, private LLM chat, AI rewriter, PDF document scanner, QR code reader, barcode scanner, OCR image to text and background eraser — in one small app that keeps your data on your phone.
