## 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

## Surf

Surf positions itself as the intelligence layer for open financial markets. The core experience is conversational: you ask a question about a token, a protocol, a company, or a market move, and the system returns an answer grounded in live market feeds, onchain events, SEC filings, and news, with the underlying sources cited so you can verify the reasoning. Around that chat experience, Surf layers a set of named products such as CryptoPulse and Cryptopedia, plus an in-browser Studio for building analysis.

What separates Surf from a generic chatbot is the data plumbing behind it. The company says its datasets are kept current, structured, and unified across fragmented sources before any model touches them, which matters because much of crypto data is scattered across exchanges, chains, and regional venues. Surf also highlights its coverage of hard-to-source markets, including multilingual Asian centralized exchange data, as a differentiator for institutional research.

For builders, Surf exposes the same intelligence through an API, an MCP server, a CLI, and reusable agent skills, so a research desk can embed crypto and equities context directly into its own agents and internal tools. Surf states it is used by more than 500,000 users across 700-plus organizations, and its developer layer is documented separately for teams that want to integrate rather than click. Surf is operated by Cybertino Inc. and is not affiliated with any exchange or broker; outputs are research assistance, not investment advice.

**Pricing & Plans:** Surf publishes a tiered pricing page covering Free, Pro, and Max plans alongside API credit packages, with annual billing options and Studio credits bundled at higher tiers. Exact figures change over time, so check the official pricing page before purchasing.

- **Cited conversational analyst:** Ask questions about tokens, protocols, or equities in plain language and receive answers backed by visible sources rather than unsupported assertions.
- **Unified multi-source data:** Market prices, onchain events, SEC filings, and news are normalized into one structured layer so the model reasons over consistent inputs.
- **Developer integration layer:** API, MCP server, CLI, and agent skills let teams wire Surf intelligence into their own agents, dashboards, and internal research workflows.
- **CryptoPulse and Cryptopedia products:** Purpose-built modules for tracking market-moving developments and for looking up structured context on projects and assets.
- **Coverage of hard-to-source markets:** Surf emphasizes structured multilingual data from Asian centralized exchanges, a category many Western data vendors handle poorly.

**Strengths:** Answers come with citations, which makes verification practical rather than a leap of faith.; Covers both onchain crypto data and US equities in a single interface, useful for cross-asset research.; Genuine developer surface area: API, MCP, CLI, and agent skills, not just a chat box.; Institutional framing and published case studies signal real deployments with funds and exchanges.

**Limitations:** It is a research and intelligence tool, not a trading or execution venue, so it will not place orders for you.; Deeper data access and higher usage tiers sit behind paid plans and API credits.; Coverage quality varies by asset and venue; niche or thinly traded markets may return thinner answers.
