Sometimes you need the meaning of one email. Sometimes you need to stay with an entire article. Attha connects quick translation with bilingual reading, helping you move from understanding another language to using it. A message comes in. Start there. Paste an email, message or passage, choose the languages and review the translation. Copy the result when you're ready to reply or quote it. Paste text to get started, without preparing a separate file. Keep your place in longer material. Import a document or subtitle file and follow its original paragraph order. Read translations alongside the source and use context-aware translation to work through articles, professional material or subtitles without losing the thread. Turn reading into practice. Use supported pronunciation aids and read-aloud tools to connect the words you see with how they sound. Organize related material into projects, return to your reading position and export results for the next task. Choose how you translate. Use the in-app cloud engine or configure a supported provider's API key. Languages, pronunciation aids and read-aloud options depend on the engine and device. Check important content against the source. Cloud processing sends the required text to the relevant service. Purchases and usage Lifetime is a separate one-time unlock. Boundless Go, Plus and Pro are monthly or yearly auto-renewing plans with shared app benefits and cloud usage. Boundless Points packs add usage credit. Different features may require different entitlements; check the specific plan, price and terms in the app before purchasing.
