## 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

## WriteMage

WriteMage is built around a simple idea: instead of copying text into a chatbot and pasting the answer back, bring the AI to wherever you are already typing. On macOS it runs as a floating panel that sits above your active app like Spotlight, so you can select text, ask for a rewrite or translation, and drop the result straight back into the document. Because it can see the surrounding context, the answers relate to what you are actually working on.

It also has memory. WriteMage keeps track of the conversation and answers with that context, and every chat is saved locally with a label so you can pick up a thread from yesterday. A Prompt Editor GUI lets you tailor the preset prompts and add your own, which turns the app into a reusable toolkit for email drafts, summaries, edits and translations.

On iOS, WriteMage is implemented as a native keyboard extension, which is the mechanism that lets an AI assistant work inside other apps on a platform that sandboxes them. The developer has been notably transparent about the business: it was developed in late 2022, was free during an extended beta, and offers both subscription plans and a one-time lifetime deal. You can either provide your own OpenAI API key for unlimited words or pay to have AI usage managed for you.

**Pricing & Plans:** Freemium-style model with a free beta download and paid plans. Basic plan (about $10-16/month billed yearly at launch sale pricing) has you bring your own OpenAI API key for unlimited words; the Personal plan (about $12-19/month billed yearly) includes managed AI usage, roughly 750,000 words per month. A one-time lifetime deal covering both macOS and iOS was also offered. Confirm current prices on the official site.

- **ChatGPT in any macOS app:** Use ChatGPT without copy-pasting: WriteMage floats on top of whatever macOS app you are in and can read the surrounding context.
- **iOS keyboard assistant:** A native iOS keyboard lets you rewrite, translate, summarize and draft text inside any app in the App Store.
- **Conversational memory and history:** WriteMage remembers the current conversation and answers with that context in mind, and saves chat history locally with labels.
- **Custom prompt editor:** A prompt editor GUI lets you customize the built-in prompts and create your own for recurring tasks.
- **Bring your own API key:** Run on your own OpenAI API key for unlimited words, or let WriteMage manage AI usage with a monthly word allowance.

**Strengths:** Works directly inside any macOS app and any iOS app via the keyboard, no copy-pasting; Context-aware answers and session memory make it useful for real documents, not just chat; Local chat history with labels and no telemetry, even during beta; Bring-your-own OpenAI API key option removes word limits

**Limitations:** The macOS app was still labeled beta (v1.1.4) at the time of review, so it may not be fully polished; In-app purchase to use your own OpenAI API key on iOS costs extra; you also need an OpenAI account; License limits macOS devices (2 on basic, 4 on personal), which is restrictive for teams; Windows, Linux and Android are not supported
