## 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

## Wolfia

Wolfia is an AI agent for the security and legal reviews that block enterprise deals. It reads the questionnaires, DDQs and RFPs buyers send, plus the portals those requests arrive in, and returns answers drawn from your own policies and documentation, with a citation for each answer. It supports common formats like SIG, CAIQ, HECVAT and DDQ, and returns XLSX, DOCX and PDF files in their original layout with answers in the right cells.

Beyond questionnaires, Wolfia covers the surrounding workflow. A Chrome extension detects and fills vendor risk management portals such as OneTrust, Whistic, ServiceNow, Coupa and Panorays. A knowledge base agent syncs sources including Google Drive, Confluence, Notion, Slack, SharePoint, Drata and GitHub so answers stay current as policies change. Reps can ask from Slack or Claude via MCP and get a cited response, and a trust center can auto-approve known prospects from your CRM, collect an NDA and share a SOC 2 report without a ticket. Customer contract intelligence gives legal a first pass on redlines, checking each clause against what your policies already promise.

Wolfia is aimed at customer trust and GRC teams at software companies selling to enterprises, where a small team supports a much larger sales organization. The Chrome extension requires an existing Wolfia account. The platform advertises enterprise-scale results, citing customers that handle hundreds of questionnaires a year with a single reviewer. Pricing is arranged by contacting the company.

**Pricing & Plans:** Contact for pricing. Wolfia offers a free start and a 'Book a demo' path, with pricing tailored to enterprise teams; specific tiers are not published on the public site.

- **Questionnaire automation:** Upload SIG, CAIQ, HECVAT, DDQ and RFP files as XLSX, DOCX or PDF and get filled answers back with the source cited for each.
- **Buyer portal filling:** The Chrome extension detects and fills vendor risk management portals such as OneTrust, Whistic, ServiceNow and Panorays, plus spreadsheets.
- **Knowledge base sync:** Wolfia pulls in Google Drive, Confluence, Notion, Slack, SharePoint, Drata and GitHub so answers always reflect your current policies.
- **Answers in Slack and Claude:** Approved reps can ask @wolfia in Slack and get an answer with the policy it came from, without waiting on the security team.
- **Contract review and trust center:** Review and redline customer contracts against what your policies already commit to, clause by clause with citations.

**Strengths:** Every answer is cited back to its source document for reviewer confidence; Fills real buyer portals through a Chrome extension, not just spreadsheets; Keeps answers current by syncing your existing knowledge sources; Extends the same knowledge base to Slack, Claude and a public trust center

**Limitations:** Enterprise-focused pricing requires contacting sales for a quote; Requires an existing Wolfia account and a populated knowledge base to be useful; Value depends on keeping source documents current; Best fit for larger sales orgs, not solo users
