What our research says

Merlin AI

Buy it if you genuinely rotate between GPT, Claude and Gemini and resent paying three subscriptions — the aggregation is the whole value. If you live inside one model, its native app is faster, cheaper and gets features first.

Pros

One subscription reaches a dozen-plus frontier and open models
Extension surfaces the assistant directly on Gmail, YouTube, Google and LinkedIn
Mobile apps sync history, so the browser session continues off desktop
Real free tier for evaluating before paying

Cons

'Unlimited' paid plans are governed by an opaque fair-use credit budget users hit without warning
Extension is desktop-Chromium only; mobile browsers get a reduced web app
Feature parity with each underlying model's own app is never complete
No developer API

Neurohelper AI

Neurohelper AI's pitch is not having to separately subscribe to a chat model, an image generator, and a video generator — one credit balance covers all of them across several providers. That convenience comes with pricing that scales quickly once a team needs API integrations or more than a handful of seats, and month-to-month billing costs about a quarter more than the advertised annual rate.

Pros

single credit balance spans chat, image, video, audio, and voiceover generation across multiple providers
10 free credits and a $1 trial let a new user test the workspace before paying
unused credits roll over rather than resetting every month, up to a cap

Cons

the headline prices are the annual rate; paying monthly costs $19 rather than $15 on Basic
API integrations are gated to the Business tier and above, not available on cheaper plans
company details beyond Turkish governing law in the terms are not disclosed
