## AI Bookmarker

AI Bookmarker addresses a problem almost every heavy browser user knows: bookmark folders overflow, titles are meaningless, and the link you saved six months ago is effectively gone. The extension runs an AI model over each page at save time and produces a title, a set of topical tags and a short summary, so entries arrive already organized rather than needing manual cleanup.

Beyond tagging, it keeps a Markdown copy of the original page content, including media such as videos from X (Twitter). That capture step is what makes the saved items reusable: you can export them to Notion, push them into NotebookLM with one click, or keep them in encrypted cloud backup and run full-text search across everything you have ever saved.

The product ships with pre-configured top-tier models, so there is no API key to set up — you log in and start saving. Cloud sync keeps the library available across browsers and devices, and the free tier is generous enough to evaluate the whole workflow before upgrading.

**Pricing & Plans:** The free plan covers unlimited bookmark creation, five AI-generated summaries per month, full-text search, and import/export. Pro is $9.99 per month or $99.99 per year and raises the AI allowance to 1,500 summaries per month, adding stable high-priority AI access plus automatic backup to Notion and to the provider's cloud.

- **Automatic tags and summaries:** Every saved page is processed by an AI model that writes a title, assigns topical tags and produces a concise summary, so nothing has to be tagged by hand.
- **Notion and NotebookLM sync:** Bookmarks, tags and summaries sync to your Notion workspace automatically, and a one-click action pushes a saved item into NotebookLM as source material.
- **Markdown page capture:** Save original web page content as Markdown, including media from platforms such as X, to build a durable personal knowledge base for AI workflows.
- **Cloud backup and full-text search:** Bookmarks are encrypted in transit and backed up to the cloud, and full-text search finds an item by any word that appeared on the page rather than by its title.
- **Works across major browsers:** Native extensions for Chrome, Firefox and Edge mean the same library follows you between browsers without export/import gymnastics.

**Strengths:** Free tier is genuinely usable: unlimited bookmarks, full-text search and no API key setup; AI summaries and tags remove almost all manual organizing work; Markdown capture plus Notion/NotebookLM sync make bookmarks reusable as AI context; Encrypted cloud backup and extensions for Chrome, Firefox and Edge

**Limitations:** The free plan caps AI summaries at five per month, which runs out quickly for heavy savers; The best integrations (Notion auto-backup, priority AI access) sit behind the paid Pro plans

## Sider

Sider's premise is that you should not have to leave the page you are reading to use an AI assistant. Its sidebar overlays the browser, detects the content in view, and responds with chat, summaries, translations or explanations using frontier models from multiple providers. The result is a lightweight research and reading workflow: highlight a paragraph, ask for a simpler explanation, translate a PDF and keep the original in sight.

Recent versions push Sider beyond chat. Sider Hand is a browser agent that works across real websites and uses your logged-in sessions to carry out multi-step jobs such as comparing prices while shopping, filling forms, doing cross-site research or triaging a Gmail inbox. Sider Code goes the other way, letting you instruct changes to a website's appearance or behaviour in plain language and preserving the customisation for next time. A Create module generates images, videos, slides and documents from the same panel.

Pricing moves from a limited free tier to credit-based paid plans aimed at heavier users. Lower plans suit occasional chat, summarisation and translation, while higher tiers add a dedicated cloud computer that keeps the browser agent running around the clock and a larger monthly credit allowance. Sider ships as browser extensions for Chrome and Edge plus desktop and mobile apps for macOS, Windows, iOS and Android, and is used by a very large installed base.

**Pricing & Plans:** Freemium. Free tier available with limited credits; paid plans advertised at roughly US$10/month for occasional use up to around US$100/month at the top tier, with higher credit allowances and a dedicated cloud computer on the upper plans.

- **AI sidebar on any page:** A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
- **Summarise and chat with documents:** Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
- **Translation and read-aloud:** Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
- **Sider Hand browser agent:** Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
- **Sider Code page customisation:** Describe a change in plain words and have Sider restyle or simplify any website, remembering the modification for future visits.

**Strengths:** Works inside the browser you already use, with no context switching; Access to multiple frontier models from one subscription; Strong reading toolkit: PDF chat, YouTube summaries, translation and read-aloud; Increasingly capable agent features for multi-step browser tasks

**Limitations:** Useful credits run out quickly on the free and lower tiers; Model availability and quota rules change over time, so expectations must be checked per plan; Some agent and code features depend on a cloud machine and heavier plans
