What our research says

ChippyAI

Chippy is a lightweight way to get ChatGPT-style help while browsing without leaving the page, and its bring-your-own-API-key model means there's no separate subscription once you're past the daily free quota. The bigger problem now is age: the extension was last updated in October 2023 and its site still talks about GPT-3.5 and a 2021 knowledge cutoff, so newer assistants such as Sider or Monica are the safer choice.

Pros

No account creation required to start using it
Conversations and API keys stay local rather than on a remote server
Covers summarizing, research, translation, and Q&A in one extension

Cons

Extension last updated in October 2023 and still built around GPT-3.5
Free quota is only 20 GPT-3.5 queries a day
Real ongoing use requires your own OpenAI API key and its associated cost
Supports only Chrome and Chromium-based browsers

Monica

Worth it if you want one subscription that reaches GPT, Claude and Gemini from wherever you already are; pointless if you live inside a single vendor's app and are happy there. The value is the sidebar and the model switching, not the intelligence, which is all rented.

Pros

Genuinely wide model roster, including image and video models, under one credit pool
Extension plus desktop plus iOS/Android means the same history follows you across devices
Separate prepaid developer API at platform.monica.im if you want the same aggregation in code

Cons

Prices are only visible after loading the pricing app, and the tier names have already shifted once (Unlimited became Max)
Advanced credits reset monthly, so heavy image or video use burns a Pro plan fast
You are a reseller's customer — outages, rate limits and model deprecations arrive second-hand
monica.cn is a separate China-market build run by a different legal entity, which confuses support and privacy expectations
