Merlin
Pros
- + Model-agnostic threads: in my testing I could switch from a GPT-4-class engine to Claude mid-conversation without losing context, which most single-model assistants can't do
- + Page-aware capture is the real differentiator — summarising a PDF, a YouTube talk and drafting a Gmail reply in one sidebar step saved me the copy-paste round trip
- + Usage accounting is unusually transparent: the 102 free queries/day and the 30-queries-per-premium-prompt rate are documented by the vendor, not hidden in an FUP
- + One login spans Chrome/Edge/Brave, web app, a native macOS app and mobile, with synced history and prompt library
- + Projects gives genuine retrieval over your own Notion/Drive/S3/URL material rather than a generic chat wrapper
Cons
- - Free tier is effectively three premium-model prompts per day once the 30-queries-per-prompt rate is applied to the 102-query pool
- - Pro is 'at least 30x' free usage under fair-use limits — the ceiling is in the terms but never quantified, so heavy users can't budget against it
- - The extension discloses it may earn affiliate commissions from sites you visit and purchases you make while using it
- - Vendor value claim ('$130 worth of value for $19') and ISO 27001/SOC 2 compliance claims are asserted, not independently verifiable from the material I reviewed
- - 26-in-1 breadth means the ancillary tools (AI detector, image editing) are shallower than the chat and summarisation core
Weglot
Pros
- + Genuinely fast to live: in my test, content detection, translation, language switcher and hreflang-tagged translated URLs all appeared without code changes
- + Visual in-place editor is the fastest review workflow I have used in website translation — click the live element, edit the string
- + Published, tiered pricing with a 14-day no-credit-card trial across all plans (€15 to €699 per month billed annually at time of writing)
- + 110+ languages with custom variants (e.g. British English, Brazilian Portuguese) and automatic SEO metadata translation
Cons
- - Word limits are fixed non-renewing pools across all languages — continuously growing sites consume them and step up tiers quickly, so realistic budgets start around the Pro tier
- - Not a full TMS: terminology enforcement, reviewer chains and project tooling are lighter than TextUnited or Smartcat
- - Website-centric — documents, software strings and mobile apps are outside the core workflow
- - Translations live in Weglot's service layer; export is available from the Advanced tier up, but plan an exit path for large sites
