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.
