## Cokeep

Cokeep targets the gap between saving information and actually learning from it. Instead of accumulating an unread reading list, it lets you collect articles, videos and links from anywhere, then reshapes them into something you can absorb — long pieces are split into smaller chunks, and AI produces instant summaries and tags so individual items stay findable inside a growing library.

The site frames the problem as information overload. Its messaging promises that you will "keep smarter, learn faster" by focusing on what matters and organising retained knowledge "like a pro". That is a retention-first pitch rather than a pure bookmarks pitch: the value is not just storing a link but making it easy to revisit and remember.

A community layer sits on top, letting you explore curated content other users have shared and collaborate with friends or teammates. On the privacy side, Cokeep states that users retain complete control of their data, including the ability to delete it or request details of how it is used at any time. The site advertises free and flexible plans and mentions an early-access waitlist, which means the product is still building out its user base.

**Pricing & Plans:** Cokeep advertises free and flexible plans for different reading and learning habits, and its homepage mentions a waitlist for launch access with exclusive discounts. No specific plan prices are published on the homepage.

- **Save from anywhere:** Bookmark articles, videos and links from across the web into a single, searchable library.
- **Content chunking:** Break lengthy articles and videos into smaller sections so you can absorb key points without the overwhelm.
- **AI summaries and auto-tagging:** Get instant summaries of what you saved, with automatic tags that keep the library organised and searchable.
- **Community discovery:** Explore curated content shared by the Cokeep community and swap insights with friends or teammates.
- **Data ownership controls:** Account authentication plus the ability to manage, delete or query your data at any time.

**Strengths:** Addresses the real problem with save-it-later tools, which is that saved content is rarely revisited; Automatic summarisation and tagging cut down on manual library upkeep; Chunking turns long articles and videos into content you can actually finish; Explicit data-ownership and deletion controls address a common privacy concern

**Limitations:** Early-stage product with a relatively small stated user base, so the community library is still thin; No published plan prices on the homepage, making budget hard to judge in advance; Chunking and auto-tagging quality ultimately depends on how well the AI parses long-form video and dense text

## 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
