## 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

## Thread Navigator

Thread Navigator is a focused reading tool for X (Twitter) threads. Long threads often break across many posts, making them hard to follow, so Thread Navigator takes a link and unrolls the whole conversation onto a single, clean page. You can read full threads without creating an account, which makes it convenient for quickly catching up on a thread someone shared.

For comfortable reading, the tool offers a Paper Mode that strips away distractions and lets you adjust font size and spacing. If you want to keep what you find, you can create a free account to bookmark threads and access your reading list across devices, or export full threads as PDF or Markdown for offline reading. A Chrome extension lets you read directly from X.

Thread Navigator also helps with discovery through a topic-based explore section, with categories spanning AI and machine learning, finance and crypto, news, entertainment, science, and marketing. The service is freemium: reading full threads and saving bookmarks stay free, while Premium adds highlighting and Notion integration.

**Pricing & Plans:** Thread Navigator is free to read full threads and save bookmarks. Premium is an upgrade that adds highlights and Notion integration.

- **Unroll Twitter threads:** Paste an X (Twitter) post or thread link and read the entire thread on one page without signing up.
- **Paper Mode reading:** Switch to Paper Mode for a distraction-free layout with adjustable font size and spacing.
- **Save for later:** Create a free account to bookmark threads and access your reading list across devices.
- **PDF and Markdown export:** Export full threads as PDF or Markdown for offline reading, with free exports going through a short unlock page.
- **Explore threads by topic:** Browse unrolled threads organized by topics like AI, finance, science, and marketing.

**Strengths:** Unrolls full threads without requiring an account; Paper Mode provides a clean, distraction-free reading layout; Free bookmarking for saving threads across devices; Exports threads to PDF or Markdown for offline reading

**Limitations:** Premium features require a paid upgrade; Some saves rely on third-party integrations such as Notion; Private or deleted posts may not be available to unroll
