## 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

## Timezone Cat

Timezone Cat is a Slack bot for teams whose channels mix languages. Instead of pasting messages into a generic translator, you connect the workspace and the bot posts translations directly in the thread, keeping the conversation readable for everyone regardless of the language they actually speak.

The distinguishing idea is context. Timezone Cat reads the surrounding messages before translating, so it can resolve the things word-for-word translation mishandles: a polite Japanese reply that is really a soft decline, a one-syllable Korean answer that means the opposite of 'yes' because the question was negative, a dropped object that only makes sense next to the two options listed above, or irony that reads as praise. It surfaces those judgments as inline nuance tags with a short note rather than silently rewriting the message.

It also handles the practical arithmetic of distributed work. Times are converted with the reader's city named, and money appears in the original currency first with the reader's currency after. Because the bot keeps daily, weekly and monthly summaries of each channel along with the decisions made in them, vague references to 'what we agreed last time' can be answered with the actual date and outcome. Setup requires a connected Slack workspace and an active subscription, plus a short description of your company's tone and a glossary so output matches your house style.

**Pricing & Plans:** Subscription-based: translation starts once the connected Slack workspace has an active plan. Exact tiers are arranged per workspace, so contact the Timezone Cat team for current pricing.

- **Context-aware translation:** Reads the thread before translating, so short answers, dropped pronouns and replies to negative questions are resolved from what came before.
- **Nuance and tone tags:** Flags what a literal reading would miss, such as a Japanese polite consideration that hides a soft no, Korean agreement that flips a negative question, or a joke that is actually a complaint.
- **Time zone and currency conversion:** Converts times with the reader's city named and shows money in the original currency first and the reader's own second.
- **Channel memory summaries:** Keeps daily, weekly and monthly summaries of each channel with the decisions in them, so vague references are resolved with the date, person and outcome.
- **Workspace defaults and glossary:** Describe your company, tone, formality and brand voice so translations sound like your organisation, plus a glossary for the terms you care about.
- **Slack-native behaviour:** Respects each channel's settings, translates only comments inside code blocks, translates text in screenshots, and answers @mentions with thread summaries.

**Strengths:** Translates in the thread instead of in a separate tool, so context is preserved; Explicitly flags nuance, tone and idiom rather than pretending translation is neutral; Handles time zones and currencies automatically for globally spread readers; Channel memory makes vague references actionable

**Limitations:** Only works inside Slack; there is no standalone web translator; Requires a connected workspace and an active subscription before translation starts; Nuance notes are model-generated, so specialist or legal wording should still be checked by a human; Company context and glossary setup is an upfront investment before quality improves
