Which one is for you
Pick Glarity if
- Fits if you read a lot of long videos and articles and want a summary in the browser
- Works for people who read pages in another language and want the translation next to the original
Look elsewhere if
- Skip it if you want to know the free limits first, because the pricing page doesn't list them
- Watch out: the pricing page names GPT-4o, Claude 3.5 Sonnet and Gemini 1.5 Pro, so the models may be older than you expect
- Tight if you read a lot: Standard stops at 150 advanced queries a month and Pro at 600
- Watch out: accounts are for one person, and the page says shared use could get the account suspended
- Not for you if you need monthly billing, as only yearly-billed prices were shown
Pick Sider if
- Fits if you want an AI side panel on every browser tab
- Works for people who want several models to answer the same question in one chat
Look elsewhere if
- Not for you if you want to know what a plan includes before paying, as the store listings don't say
- Skip it if you'd buy the $49.99 Pocket Plan for desktop use, because its credits are for mobile only
- Pricey if you need Unlimited, at $39.99 a month, with Pro at $19.99 in between
- Watch out: the App Store also lists a legacy Basic plan, a $12.99 Nano plan, a $40.00 Plus plan and a second Pro item at $65.00 a month, none of them described
- Tight if you plan to stay free, since neither store listing says how much usage comes without a plan
How we grade them
| 2.4GPAGlarityFair | 3.0GPASiderVery good | |
|---|---|---|
| Value for money | B$7.49 a month on yearly billing, which is inside the cheaper quarter of what AI assistants charge ($9 and under). Only yearly prices are shown, and the dearer plans carry discount banners with no end date. | CBasic is $9.99 a month on the US App Store, which is ordinary money here, with Pro at $19.99 and Unlimited at $39.99. The listings don't say what any plan includes, and Sider's own site blocks automated readers, so web prices may differ. |
| Free plan and trial | CThe homepage calls the extension free, but the pricing page gives no free allowance and no trial, so you can't tell where the cap sits before you hit it. | CThe apps and the browser extension are free to install, and the Chrome listing mentions free multi-chatbot support. Neither store listing says how much usage comes without a plan, so you'll meet the limit before you can read it. |
| Features | CSummaries for YouTube, pages, PDFs and search results, plus translation and a writing helper. The listing's own notes say the model list may be out of date and the plans are capped by queries. | BIt covers the job: a panel on any tab with GPT, Claude, Gemini, Grok and DeepSeek, or several at once in a group chat, questions about PDFs, pages and open tabs, YouTube videos boiled down, grammar and translation, and Wisebase for your files. Monica and Merlin do much the same. |
| Ease of use | BNo rating on record, but it's an extension you add to the browser and start using: no setup beyond picking a plan if you hit the limit. | A4.7 from about 4,300 App Store ratings. Install the extension and the panel is on every tab, so there's no copying between windows, and a Fusion model picks which AI handles each request. |
| Platforms and integrations | CChrome, Edge, Safari, Firefox and Opera as an extension, and nothing else. No phone app and no standalone desktop app. | AA sidebar for Chrome, Edge and Safari plus apps for Mac, Windows, iPhone and Android on one account, and it works inside Gmail, YouTube, Google and Bing. One catch: Sider says the mobile Pocket Plan's credits can't be spent in the desktop browser. |
| Best for | summaries of videos and web pages in the browser | an AI side panel on every browser tab |

Worth knowing
Glarity

- Accounts are for individual use only, and the page says multi-user access could lead to suspension.
- Only the yearly-billed prices could be read; no monthly-billing prices were displayed.
Sider
- Sider's website answers automated readers with a security check, so the prices here are US App Store in-app prices and web prices may differ.
- The store listings do not say how much usage the free tier includes or what each paid plan adds.
- Sider told an App Store reviewer that the Pocket Plan is for mobile use and that its credits cannot be spent in the desktop browser.

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
