ChatOn

Nova

ChatOn

The website lists no prices; they are shown in the app stores and in the web app before purchase, and may vary outside the US.
The free plan is limited to basic chat: advanced models, web search, uploads and image generation all need Premium.
Vendor pages disagree on the free plan's model: the plan table says GPT-5.6, while the FAQ says GPT-4o mini.
The US App Store lists the iOS app as iPhone only.

Nova

Prices are not on the website: the vendor says they are shown in the app, and the US App Store lists the same plan at several price points.
The vendor's pages do not say where free use stops or which features need a subscription.
The site lists macOS, but the Mac version is the iPad app: the App Store marks it as not verified for macOS and requires an Apple M1 chip or later.
Refunds are generally limited to requests made within 3 days of purchase and after fewer than 20 messages.

ChatOn

Several models in one chat: Premium opens GPT-5, GPT-4o, o4-mini, Claude Sonnet 5, Gemini 3.5 Flash and Perplexity Sonar, and the model can be switched to suit the task.
Real-time web search: Questions can be answered from current web results through Perplexity Sonar and Sonar Pro. Web search is a Premium feature.
Image generation and Pic Transformer: Creates images from a description, edits existing ones in the chat, restyles an uploaded photo with preset looks, and turns a photo into a short video.
Doc Master: Summarizes, rewrites, translates and answers questions about PDF, DOC, TXT and EPUB files. Text in a photo can be extracted with OCR and brought into the chat.
Writing tones and ready-made prompts: Replies can be set to tones such as Professional, Friendly or Persuasive, and a prompt library covers captions, emails, resumes, travel plans and similar everyday tasks.
Web and mobile sync: A single purchase applies across the web app and the iOS and Android apps, so the subscription does not need to be bought again on another device.

Nova

Several models in one app: The App Store listing names OpenAI GPT-5.6, Google Gemini 3.6 Flash, Anthropic Claude Opus 5, Kimi K3, xAI Grok 4.5 and DeepSeek V4 Pro as the models behind the assistant.
Web search and research: Searches the web for real-time information, and a deeper research mode compares information and analyzes sources on a topic.
Writing help and proofreading: Drafts and rewrites essays, posts and other text, checks grammar, clarity and tone, and translates between more than 140 languages.
Image generation and voice mode: Generates images from a prompt, and a voice mode allows hands-free spoken conversations with the assistant.
Files and scan-and-solve: Works on files such as Word and Excel documents, and can scan a document, question or homework problem and answer it.
Cross-device sync: Chats continue across devices, with a web app at chat.novaapp.ai alongside the mobile apps.
