ChatHub vs Fello AI

ChatHub

• Comparing how several AI models answer the same prompt
• People who want many models under a single subscription
• Extension users who would sooner run on their own API keys

Fello AI

• Apple users who want one native app for many AI models
• People who want model access without managing API keys
• Turning notes and PDFs into Word, Excel or PowerPoint files

ChatHub

• The size of the free usage quota in the web app is not published; more usage and the premium features need a paid plan.
• Pro limits advanced models to 1,500 queries a month and document uploads to 300. Only Unlimited removes those caps.
• Custom chatbots for your own OpenAI-compatible endpoints are available only in the browser extension.
• Refunds are offered within 7 days of purchase, prorated by days used, and not for renewals.

Fello AI

• It is available on Mac, iPhone and iPad only; the vendor says there is no Windows or Android version.
• Free users get 5 questions per hour with premium models before the app switches to its Free AI model.
• The vendor's FAQ lists lower prices ($3.99 weekly, $9.99 monthly, $79.99 yearly) than the US App Store listing. The price charged is the one shown in the app.
• Billing runs through Apple, and existing ChatGPT, Claude or Gemini subscriptions cannot be connected or used inside the app.

ChatHub

Side-by-side answers

One prompt goes to up to six chatbots at once, and the replies appear next to each other so you can compare them and pick the strongest.

One subscription for many models

Paid plans include GPT, Claude, Gemini and 20+ other models with no API keys needed, split into basic and advanced tiers that each have a monthly quota.

Your own accounts or API keys

The browser extension is free and can run on your own accounts or API keys. Custom chatbots can be added for any OpenAI-compatible API, such as OpenRouter or Ollama.

Web access and file analysis

Premium features add real-time web access and chat with images, PDFs, spreadsheets and other uploaded documents.

Image and video generation

Creates images with models such as Nano Banana, FLUX.2 and Stable Diffusion using monthly credits. Extra credits cost $1 per 500, from $5, and are valid for 3 months.

Prompt library and chat tools

Saves prompts for reuse, searches chat history in full text, summarizes several chats with one click, previews generated code and shares conversations.

Fello AI

20+ models in one app

Switch between GPT, Claude, Gemini, Grok, DeepSeek, Kimi, Perplexity and other models from one menu, with no separate subscriptions. Reasoning mode is available across the major models.

Adaptive Search and Deep Research

The app decides when a question needs live web data and answers with sources. Online Search and Deep Research can also be picked by hand from the skills menu.

Skills that produce files

Describe what you need and the app builds a PowerPoint deck, Word document, Excel sheet or PDF in the conversation. A Podcast skill turns a document or topic into a two-host audio episode.

Files and images

Upload up to 16 files per conversation at up to 16 MB each, including PDFs of up to 500 pages and Office documents. Image models generate pictures and edit existing ones from a prompt.

Floating chat bar and dictation

On the Mac, Option-Space opens a chat bar over any app. Voice dictation records up to five minutes at a time and transcribes in more than 100 languages.

Projects, pins and bookmarks

Projects hold shared background, instructions and files for related chats. Conversations can be pinned, replies bookmarked, and everything searched in full text.
