Merlin AI

Merlin AI is a paid assistant from Foyer that puts several AI models behind one account. Its pricing page lists a Free plan at $0 with limited access to basic and Plus-level models, basic image generation and limited access to 70+ AI tools. With the yearly option selected, Pro is shown at $19 a month billed $228 for a year, and Teams at $15 per seat a month billed $180 for a year, with a minimum of 2 seats.

The page also carries a banner for Merlin Pro at $5 a month as a special offer, and it does not say how long the offer runs or which billing period it applies to. The price for paying month by month is not legible in the page text, so it is not stated here. Read the number on the live page before you pay.

Pro lists unlimited access to basic models, 50x usage on Plus-level models, access to exclusive models named GPT 6.1 Sol and Claude Opus 5.5, advanced image and video generation, unlimited access to 70+ AI tools, sync across devices and fast-track support. The FAQ puts the context window for Pro at 100k tokens and says Merlin provides no direct API access.

The word “unlimited” is qualified on the same page: Pro is bound by fair use limits and offers at least 30x the usage of Free. The page also describes a top-up feature for buying extra credits after you hit a limit. Teams adds member management, a usage dashboard, a larger context window on all models and a claim of SOC2, GDPR and ISO 27001 compliance.

• Web app: chat with the listed models in the browser.
• Chrome extension: summarize, write and ask on the page you are viewing.
• Desktop app: a native Mac app with Merlin Agent.
• Mobile apps: iOS and Android, with synced history.

The terms are more specific than the plan table. For a standard paid account, usage costing Merlin more than $100 in a month ends service for the rest of that month, and usage above $16 in a day ends it for that day. Accounts on a promotional discount get limits that are proportionally lower. Merlin calculates the cost from the token use of the underlying models plus cloud costs.

The terms also list reasons for suspension without a refund, including sharing an account between people, running scripts over Merlin and “outlier usage” judged at the company’s discretion. Editorial assessment: heavy daily users of the strongest models should read section 12 of the terms before choosing an annual plan, because the plan page does not state these figures.

The privacy policy says the browser extension, once installed and permitted, sends Activity Data for pages you visit to Merlin’s servers: the URL, previous URL, referrer, timestamp, user ID, browser, operating system, navigation type and HTTP status code. It says page content is not collected unless you use a feature that needs it. The policy also lists prompts, uploaded files and conversation history as User Content, retained for 30 days after a deletion request.

One clause matters for budget plans: data handling for plans billed below USD 5 a month follows the free-user policies, and full SOC2, GDPR and ISO compliance is guaranteed from USD 5 a month. The terms name Foyer Tech Incorporated in Delaware, while the privacy policy names Foyer Technologies Private Limited, so check which entity contracts with you.

1. Run each task in Merlin with the closest model it offers and in your current tool, using the same input text.
2. Record the model Merlin used, the time taken and whether a usage limit stopped you.
3. Open the extension on a page you do not mind sharing and note what it asks permission to read.
4. Check the live price and billing period before paying.

Accept the switch only if the answers are as usable as your current tool’s and no limit interrupts a normal day. Reject it if the extension permissions or the usage terms conflict with your work. Leave the observed result blank until the exercise is run.
