## Actionbook

Actionbook positions itself as a coworker rather than a chatbot: instead of answering questions, it finishes work. Installed as a Chrome or Edge extension, it opens the sites you already use, reads the data sitting behind your logins, and consolidates scattered dashboards, lead lists, reports, and threads into a single finished result that you can share in one link.

The product leans heavily on traceability. Every number in a generated dashboard links back to the page it came from, so you can open the original and verify it before you use or forward it. Finished runs can be saved as reusable "Plays" that keep the steps that worked, which makes repeat jobs faster, more accurate, and less credit-hungry than starting from scratch each time.

Because the agent runs in your own browser with your own sessions, credentials stay on your device and never reach the model. You approve important actions and can stop any run at any point. Typical use cases include auditing social analytics, researching prospects, tracking ad performance, and compiling competitor reviews from Product Hunt, X, and Reddit.

**Pricing & Plans:** Free tier: 5,000 welcome credits plus 500 refreshed daily, all features included, no credit card. Pro: $20/month for 10,000 credits with Max models and one-month rollover. Team & Enterprise: custom pricing with a shared credit pool, shared Plays, and admin controls. Top-up credits cost $10 per 5,000 and never expire.

- **No-API data collection:** Gather data with built-in connectors or from any page you open in your browser, including sites behind logins and paywalls.
- **One-click dashboards:** Turn raw captures into a clear, shareable dashboard with platform cards, charts, and top-item tables.
- **Sourced insights:** Every number links back to its original page, so you can verify each claim before acting on it or sharing it.
- **Reusable Plays:** Save a completed run as a Play that keeps the successful steps, making the next execution faster and more token-efficient.
- **Local credentials:** The agent works inside your own browser sessions, so usernames, passwords, and cookies never leave your machine.

**Strengths:** Works on any site you are signed into, no API keys or integrations required; Every insight is traceable back to its source page; Runs locally in your browser, so credentials never leave your device; Generous free tier with daily refreshed credits and all features unlocked

**Limitations:** Requires installing a browser extension, which rules out headless or server-side workflows; Credit consumption varies widely with task complexity, so costs are hard to predict upfront; Best results depend on the stability of third-party sites the agent drives

## 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
