ZIMA is the all-in-one AI chat app: Claude, ChatGPT, and Gemini in one place, plus AI images, video, music, voice chat, and a Gallery of everything you create. Chat with Claude Fable 5.1 and Claude Opus 5.5 from Anthropic, GPT-6 Astra, Sol and Luna from OpenAI, and Google's Gemini 3.8 Flash and Gemini 3.1 Pro — 32 models, one subscription, one clean, fast interface. One App. Every Model. Stop juggling AI subscriptions. Pick the right model for each task — quick answers, deep research, writing, coding — switch mid-conversation without losing context, and turn on extended thinking for the hardest problems. Start free, no account needed, with Claude Sonnet 5.5, GPT-6 Luna, Gemini 3.5 Flash, and more. Upgrade to Lite, Pro or Max for every premium model and higher daily limits. AI Image Generation Create images in any chat just by asking. Choose your image model in Image Options: OpenAI's GPT Image 2.5, Google's Nano Banana 2, ByteDance's Seedream 5.0 Lite and Pro, or Black Forest Labs' FLUX.2 Max. Ask for up to 4 variations and each appears the moment it's ready. Tap an image's tag, like A2, and say what to change ("make A2 warmer"), or pick a one-tap adjustment. New image models arrive without an app update. AI Video Generation Make short videos with sound in any chat. Gemini Omni Flash is the default, or choose ByteDance's Seedance, MiniMax H3, or Google's Veo 3.1 in Video Options. Ask for up to 4 versions at once, bring a photo to life, then edit or extend any clip just by asking: "make it nighttime," "keep going." Clips play right in the chat. Music, Sound Effects & Speech Ask for a song with lyrics or an instrumental, a sound effect or looping ambience, or text read aloud in one of ten natural voices — even as a dialogue. Powered by ElevenLabs, every track plays right in the chat. Your Gallery Every image, video, and track you've made, across all your chats, in one place. Browse by date or by chat, filter by type or model, and search your prompts. Jump back to the chat where something was made, or use it as the reference for a new chat. Save, share, or delete. Voice Chat & Dictation Hold the mic and choose Voice chat for a real spoken conversation with ChatGPT or Gemini, and switch mid-call. Show it a photo or document, share your camera with Gemini, and get answers from the live web — every call is transcribed into your chat. Or tap the mic to dictate: your words fill the message box as you speak. Know When It's Ready Turn on notifications and ZIMA tells you the moment a video, song, or image set is done — or when a reply finishes after you've left. Web Search & Link Reading Answers grounded in the live web, with sources you can tap. Paste a link and ask about it, or have ZIMA pull real photos from the web into the chat. Gmail & Google Drive Connect your Google account and ZIMA can search your email and files — "what did Sarah say about the launch date?" It drafts emails for you to send yourself (ZIMA never sends) and creates Google Docs, Sheets, Slides, and Forms in your Drive. Every read shows a card in chat, so you always know what was accessed. Real Files, Created in Chat Ask for a report, spreadsheet, or deck and get a downloadable Word, PDF, Excel, PowerPoint, or CSV file right in the conversation. Preview, download, or save to Drive, then refine by asking. Upload & Ask Attach images, PDFs, Word docs, spreadsheets, and more. ZIMA reads them, answers your questions, and remembers earlier attachments even in long conversations. Always Organized Every chat is saved, searchable, and synced between iOS and the web. Edit or delete your messages anytime. Clear Privacy Your messages go to the provider of the model you pick, solely to generate your reply — never to train AI models. A plain-language "AI & Your Data" page shows exactly what ZIMA shares with AI providers, before first use and anytime in Settings. Terms of Use: https://chatzima.com/terms-of-service

Verdict
The clearest difference is review sentiment: ChatZima at 100% against VCL go's 50%. ChatZima also leads on rating (4.7 vs 3.0) and ratings volume (25 vs 2). VCL go's advantage is in-app purchases (none vs 10) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. ChatZima sells 10 in-app purchases, starting at $10.00 per month. VCL go asks for nothing beyond the download.
ChatZima holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: ChatZima has 25 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 50% of VCL go's written reviews are positive against 100% of ChatZima's.
