## Merlin AI

Merlin is built around a simple idea: instead of opening a separate chat tab for every task, you summon one assistant with a click while staying inside whatever you are reading or working on. The extension injects a sidebar on any web page, so it can read the article, the PDF, the YouTube transcript or the Gmail thread you currently have open and respond with that context already loaded. That makes summarization, rewriting, replying and research feel like part of the page rather than a separate tool.

Under the hood Merlin routes requests across a broad set of models — OpenAI's GPT family, Anthropic's Claude, Google's Gemini, DeepSeek, Mistral, Meta's Llama and others — so you can pick the model that suits a task without holding separate subscriptions for each. Beyond chat there is an image generator with multiple models and aspect ratios, a search mode that answers questions from live web results, document and video summarization, and a library of saved prompts. Newer additions like Projects (reusable knowledge bases) and Crafts (generated diagrams, mind maps and charts) push it toward light research and prototyping work.

Merlin is available as a Chrome extension, a web app, an iOS app and an Android app with synced history, custom prompts and custom bots across devices. The vendor highlights GDPR, ISO 27001 and SOC 2 alignment for data handling, and positions itself as accessible in 200+ countries where some other assistants are restricted. It is squarely a productivity assistant rather than a developer platform.

**Pricing & Plans:** Freemium. A free tier covers everyday use, and Merlin Pro is promoted at $2/month as a special offer, with the standard plan advertised around $19/month billed annually and described as replacing roughly $130/month of separate AI subscriptions. Paid tiers add higher limits, more capable models and advanced features.

- **Multi-model access in one place:** Switch between GPT, Claude, Gemini, DeepSeek, Mistral and Llama class models from a single interface instead of juggling separate subscriptions.
- **Universal page summarization:** Summarize articles, YouTube videos, PDFs and documents in place, then ask follow-up questions grounded in that content.
- **Writing and social drafts:** Draft and reply to emails in Gmail, compose posts and comments for X and LinkedIn, and repurpose web pages or videos into blogs and articles.
- **Image generation:** Generate images from prompts using more than 20 image models and multiple aspect ratios for web and social output.
- **Projects, Crafts and custom bots:** Build reusable knowledge bases, generate diagrams and charts from a prompt, and assemble custom chatbots from your own instructions and context.

**Strengths:** Replaces several separate AI subscriptions with one interface and one bill; Works inline on any page, so context is captured without copy-pasting; Covers a wide range of tasks: chat, summarization, writing, images, search and light research; Syncs across browser, web, iOS and Android with custom prompts and bots preserved

**Limitations:** The free tier is limited, and heavy use pushes you toward the paid plan; Covering so many features means individual tools may be less deep than dedicated apps; Requires trusting a third party with the pages and documents you send it, even with the stated compliance certifications

## Postli

Postli was created for one narrow job: helping people publish better content on LinkedIn more consistently. Instead of a blank text box, you start from a library of templates pulled from posts that already performed well, fill in your own specifics, and let the built-in AI assist with drafting and polishing. The result is a repeatable workflow that removes the friction of staring at an empty editor.

The platform is aimed at creators, founders, marketers, and sales professionals who treat LinkedIn as a real channel for leads and audience growth. Alongside the template library, Postli offers hooks, hashtag and idea generators, a LinkedIn post previewer, and curated feeds of well-known LinkedIn authors so you can see the patterns behind strong posts.

Because everything is tuned for LinkedIn rather than general writing, Postli positions itself as a focused alternative to generic AI writing tools and broader social scheduling suites. It starts free and scales into paid tiers for people publishing regularly.

**Pricing & Plans:** Freemium. A free tier covers core access to templates and the post editor. Paid plans unlock larger template libraries, more AI generation, and additional creator resources. Check the pricing page for current tiers.

- **1,000+ viral post templates:** Browse a large, curated collection of high-performing LinkedIn post frameworks and fill them in with your own details to publish faster.
- **Hook and headline libraries:** Get opening lines and hooks modeled on what actually stops the scroll on LinkedIn, so more of your audience reads past the first line.
- **Creator and influencer feeds:** Study real posts from established LinkedIn creators across growth, SaaS, marketing, and founder topics to learn what performs.
- **AI drafting and editing:** Generate or refine a post with AI, then adjust tone, structure, and length before you publish.
- **Preview, ideas, and hashtag tools:** Preview how a post will render in the LinkedIn feed, generate hashtags and ideas, and plan content so you never start from a blank page.

**Strengths:** Free tier makes it easy to try before paying; Large library of LinkedIn-specific templates and hooks; AI drafting helps you publish more consistently; Curated creator feeds give you real examples to learn from

**Limitations:** Purpose-built for LinkedIn, so it is not a fit for teams focused on other platforms; Some of the deeper template and influencer libraries sit behind paid plans; Output quality still depends on how well you brief the tool with your own voice and examples
