Merlin AI
Editor's pickEvery top AI model in one place — ChatGPT, Claude and Gemini on any website
Our verdict
Why use it? Because it's the shortest path from 'I should use AI more' to actually using it daily. No setup, no prompt engineering degree — open any page, ask, get a good answer from the best model for the job. Start free; if the daily limit annoys you within a week, that's your sign to upgrade.
Merlin AI is the simplest way to actually use AI every day. Instead of juggling five subscriptions and copy-pasting between tabs, you get one assistant that lives in your browser and in a web app: chat with the best models from OpenAI, Anthropic and Google side by side, summarise any YouTube video, article or PDF in one click, and draft emails and replies without leaving the page you're on.

Alternatives to Merlin AI
n8n
Open-source workflow automation you can host yourself
n8n is a node-based automation platform you run on your own server, with first-class AI agent nodes built on LangChain primitives. It is far more flexible than no-code rivals and much cheaper at volume, if you are willing to operate it yourself.
Gamma
Prompt-to-presentation decks that look designed, not templated
Gamma turns a prompt or a document into a deck you can edit in place, then publish as a website or export to PowerPoint. The default layouts look finished rather than stock, and the share-as-a-link path is genuinely useful for updates and one-pagers.
Zapier AI
Automate work across 7,000+ apps with AI steps and agents
Zapier folds AI into its automation platform: AI actions inside Zaps, a natural-language builder, and agents that run multi-step workflows across thousands of apps. It is the pragmatic way to wire AI into tools that have no AI of their own.
Fireflies.ai
AI notetaker with conversation analytics rolled up across your team
Fireflies records, transcribes and analyses meetings on every major conferencing platform, then aggregates insights across the team: topics covered, talk time and coaching scores. The free plan is surprisingly capable for individuals, but the analytics are what teams pay for.
