One $30 app now runs GPT, Gemini, Claude, and Sonar side by side

# What the offer is ChatOn is an app that combines multiple major language models — GPT, Gemini, Claude, and Sonar — into a single assistant. For new users, the app's Premium plan is on sale for one year at $29.99 (regular price $39.99). The deal requires redeeming a code within 30 days of purchase and is final once redeemed.

# What ChatOn includes ChatOn provides a set of capabilities beyond simply switching between models:

• Model switching: Choose between GPT, Gemini, Claude, and Sonar within the same conversation flow.
• Real-time web search: The app runs live searches and returns source links for results.

• Document handling: Upload PDF, DOC, TXT, and EPUB files for summarization, rewriting, or translation.

• Ready-made prompts: More than 100 prebuilt prompts for writing, research, and planning tasks.
• Cross-platform sync: Chats sync across iOS, Android, and the web under one account.

More than 100 million downloads are reported for ChatOn on iOS and Android. Reviewers say switching between models feels smooth and stable, and the interface remains simple even with many features packed into one app. ChatOn won a Lovie Award for Best User Experience.

# Limits and fine print

# Why someone might choose this instead of separate subscriptions People who compare multiple models often end up with several subscriptions to see which model performs best for a specific task. ChatOn consolidates access so you can ask the same question to different models without juggling accounts or tabs. It also bundles non-chat capabilities (image/video generation, OCR, and document tools) into the same account.

# Practical considerations before buying

• Verify the sale applies to your device and region and that you qualify as a "new user."

• Redeem the code within the 30-day window and know that redemption is final.
• Consider whether you need ongoing access to the same mix of models after the year ends or if a one-year access window fits your workflow.

# Bottom line If you regularly test answers between models or want a single app that handles chat, web search, media generation, and document processing, ChatOn's discounted one-year Premium plan is a low-cost way to consolidate those tools. Confirm the daily usage caps and the new-user restriction before committing.
