Strengths and limits
Merlin AI
Strengths
- Several model families in one account: The pricing page lists models from OpenAI, Anthropic, Google, DeepSeek and xAI, so you can compare answers without separate sign-ins.
- Works where you already browse: The Chrome extension offers summarizing and writing on the page you are viewing, alongside web, desktop and mobile apps.
- A Free plan to try first: Free costs $0 with limited access to basic and Plus-level models, so you can test before paying.
Limits to plan around
- Fair use limits sit behind unlimited: The terms end service for the rest of the month above $100 of usage cost and for the day above $16, and the plan table does not state this.
- Extension sends visit data: The privacy policy lists page URL, previous URL, referrer and user ID among data sent to Merlin's servers.
- No API and a 100k context: The pricing page says there is no direct API access and the Pro context window is currently 100k tokens.
YesChat
Strengths
- One balance for several providers: Switch between OpenAI, Anthropic, Google, xAI and DeepSeek models without separate subscriptions.
- Visible cost per reply: Receipts show weighted tokens and credits, and failed requests are charged 0 credits.
- Usable free tier: Fifteen daily agent-mode messages need no card and reset each day.
Limits to plan around
- Model access is plan-gated: Free excludes Claude and Gemini; Opus 5 needs Ultra, while GPT-6 Astra and Claude Fable 5.1 need Max.
- Narrow refund window: Refunds are limited to 3 days and to accounts that used no more than 20% of Advanced Credits.
- Broad license over submitted content: The terms grant the operator a worldwide, perpetual license to user content, including publication to others.

Comparing tools from different categories is fine, and often useful — a writing assistant and a research tool solve different halves of the same job. The table will show you exactly where they diverge.
Questions about comparing tools
How does the comparison work?
Add two tools to the comparison tray from any tool card, then open this page. The table pulls each tool's verified plan details, platforms, strengths and limits from its profile, so both columns carry the same kind of evidence, with a separate source-check date for each tool.
Do you declare a winner?
No. The table sets two tools against each other on documented facts, not on a score. Which one wins depends on your task, your budget and your usage volume — three things we cannot see from here.
Why are some cells empty or marked unverified?
Because we could not confirm that detail on the vendor's own pages. Rather than filling the gap with a figure from elsewhere, we mark it and say why on the tool's profile.
Can I compare more than two tools?
Not at once. Two columns keep the differences readable and force a real decision. Remove either selected tool to replace it, or clear both to start a new pair.
Every figure in the table above comes from the linked profile, where the source and the verification date are listed. Browse all tools or read the editorial policy.
