Monica alternatives in 2026, compared on price and memory

Monica's advantage is placement: it sits beside whatever you are reading. Its weakness is the same thing. A sidebar is a utility, not a place where a project lives. If you want the project to persist, the alternatives below are the ones to compare.

Who should switch

• You want one project thread instead of a sidebar on every tab.
• You want memory that applies to the work, not only the page.
• You want documents and artifacts next to the chat.
• You want a flat plan instead of a credit balance.

1. Sider

Sider is the closest like-for-like swap. It is a browser sidebar with many models and a free tier. If the sidebar is the part you actually use, stay in that category.

• Price: from $8.30 a month billed annually, $24.90 Plus, $133.30 Ultra.
• Best for: a sidebar on every tab.
• Trade-off: utility, not a workspace.

2. Merlin

Merlin is the daily-allowance alternative. It gives a generous free daily pool and a browser extension, with a $29 monthly plan or $19 billed annually. It is a good fit if you want many small questions answered without a credit meter.

• Price: free 102 queries a day, $29 monthly or $19 annual.
• Best for: daily small tasks.
• Trade-off: memory is an afterthought.

3. Swirl

Swirl is the workspace alternative. Memory is the product, the models can change inside one thread, and replies can become editable documents and visualizations. It is the opposite bet from a sidebar.

• Price: five free messages, then $15, $30, $60, or $100 a month.
• Best for: work that spans weeks.
• Trade-off: not a browser sidebar.

4. ChatHub

ChatHub is the side-by-side option. If you used Monica to compare answers, ChatHub makes the comparison the product. It is cheaper to try than a full workspace.

• Price: $19 monthly, $14.99 annual, $39 unlimited.
• Best for: comparing two models.
• Trade-off: a comparison toy, not a memory layer.

5. TypingMind

TypingMind is for people who want to own the stack. Bring your own API key, pay providers directly, and get a strong local-first workspace. More setup, more control.

• Price: $39 one-time Standard, plus API costs.
• Best for: developers and power users.
• Trade-off: setup before the first message.

The question is not which sidebar is best. It is whether you want a sidebar at all. If the answer is yes, Sider and Merlin are the direct alternatives. If the answer is no, Swirl is the workspace bet.
