## 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

## Spion

Spion attacks a very specific kind of wasted time: the small browser rituals you repeat every week. Copying a metric out of a CRM, pasting it into a spreadsheet, fixing a typo, then posting the update in Slack — six steps, three tabs, eleven minutes, every Monday. Spion is a Chrome extension that records that sequence once, quietly, and then works out what the underlying workflow actually is.

The interesting part is what happens after recording. Rather than replaying your clicks back at you, Spion reads the pattern and rebuilds it as a cleaner workflow with fewer steps, a sensible trigger, and a suggested summary step you probably skipped. It then hands that workflow off to whatever automation stack you already run — n8n, Make, Zapier, Workato, or a Claude prompt — or turns it into an editable PDF guide for colleagues who need to follow the process by hand.

Spion is aimed at teams drowning in recurring operations work: sales pipeline and lead routing, marketing reporting, IT onboarding, finance close and invoicing, HR headcount, legal renewals, customer success health checks. The pricing is freemium and deliberately low-friction — a genuinely free tier, $12 per month for Pro, and $60 per month for a five-seat Team plan. Privacy is handled by keeping recordings local in the browser and sending only captured steps for analysis, with no advertising trackers.

**Pricing & Plans:** Freemium. Free forever includes 5 recordings and 5 exports per month with full AI analysis. Pro is $12/month for 50 recordings and unlimited exports. Team is $60/month for 5 seats and 300 recordings per seat. Annual billing saves 25 percent, and no credit card is required to start.

- **One-click browser recording:** One click starts capturing your actions across tabs, forms and dashboards, with zero configuration and no script to write.
- **AI pattern detection:** Spion scans the recorded steps, identifies the repeating pattern, and rebuilds it as an optimised workflow with a proper trigger rather than replaying every click.
- **One-click export to six targets:** Finished workflows drop into n8n, Make, Zapier, Workato or Claude as importable files, recipes or prompts, so you keep using the tools you already trust.
- **Step-by-step SOP and PDF guides:** Spion also generates an editable, enablement-grade PDF or SOP so colleagues can follow a documented process rather than guess.
- **Repetition tax calculator:** A slider-based calculator estimates the hours a task steals each year, making the case for automating a given ritual concrete.

**Strengths:** Turns undocumented clicking into a structured, runnable automation; Exports to the platforms teams already pay for instead of a locked-in runtime; Genuinely free tier with full AI analysis and every export format; Generates human-readable SOPs and PDFs alongside machine automation

**Limitations:** Browser extension is Chrome-focused rather than cross-browser; Free tier caps you at 5 recordings and 5 exports per month; You still need an existing automation platform (n8n, Make, Zapier, Workato) to run the finished workflow; Recorded workflows can break when a target site changes its interface
