MightyMouse vs ChatGPT Plus
The $20 subscription most people already have is ChatGPT. Here is what the same money buys somewhere else, and what you would miss.
Short answer: ChatGPT Plus is $20 a month for OpenAI's models, while MightyMouse gives you 33 models for text, images and video from many labs in one account, with Pro also at $20 a month. MightyMouse's chat is newer and simpler: today it has no web search, no voice and no PDF upload.
You have a question that one model handles badly. You paste it into a second tool, a third, and now you pay for three subscriptions to get one good answer. That is the itch this comparison scratches.
What ChatGPT Plus is, from OpenAI's pages
- Price. OpenAI's Codex pricing page, read on 2026-09-29, lists Plus at $20 a month and Pro from $100 a month.
- Models. The same page lists OpenAI's own models: GPT-6 Astra, GPT-6 Sol and GPT-6 Luna. So Plus is one lab's models.
- Codex. That page says Codex is included in Free, Go, Plus, Pro, Business, Edu and Enterprise plans, with limits per five-hour period.
For everything else Plus includes, see OpenAI's own pricing page at chatgpt.com/pricing.
What MightyMouse's chat does today
In your browser at app.getmightymouse.com:
- 33 models. 10 for text, 12 for images and 11 for video. Text includes Opus 5.5, Sonnet 5, GPT-6 Astra, Gemini 3.1 Pro, Grok 4.7 and Kimi K3.
- Pick the model for each message. A menu at the top of every chat switches it.
- Two chats side by side. Open a second chat next to the first, give each its own model, and compare the answers.
- Images and video come back in the same thread. Ask, and the result shows in the chat with a Download link.
- Attach things. Drop in up to four images, or a text file such as a CSV, notes or code.
- Projects. Group chats by project. Projects you make on the web also show up in the Mac app.
- Share a link. Turn an answer into a link. If the answer is a small web page, the link opens it as a page.
- Works on your phone. It is a web app, so it opens in your phone's browser.
Every model is on every plan. Free gets you started. Pro is $20 a month and Max is $60, and the difference is how much usage you get, not which models.
What you would miss
MightyMouse's chat is newer than ChatGPT. Today it does not have:
- Web search. The models answer from what they know, without looking things up live.
- Voice. There is no talk-to-it mode in the web chat.
- PDF upload. You can attach images and text files, not PDFs.
- Editing or regenerating. You cannot edit a message you sent, or ask for a fresh answer with one click.
- Stop. You cannot stop an answer part way.
- Custom instructions. There is no setting that carries your preferences into every chat.
- Long answers. Each reply is capped at 4,096 tokens, which is a few pages of text.
Who should pick which
- Stay with ChatGPT Plus if you live in web search, voice and PDFs, and you are happy with OpenAI's models.
- Pick MightyMouse if you want to try the same question on Claude, GPT, Gemini and Grok, or if you want image and video models next to the chat, or a coding agent on your GitHub in the same account.
