## DeckAssistant

DeckAssistant is a Stream Deck plugin built for people who constantly shuttle text between applications and an AI chat. Instead of copying a paragraph, switching windows, pasting and copying the answer back, you select the text and press a mapped key. The plugin sends the selection to the AI with the prompt you configured on that button and returns the result, so the round trip becomes a single physical action.

The plugin pairs with a web application that is designed as a more workable ChatGPT interface. There you get folders to organise chats, custom prompts, message editing, history search, favourites, data export, screenshot export, a prompt library and shareable chats, plus Google lookups and image generation. Conversations started from a Stream Deck button continue in the web app, so the button becomes a shortcut into an organised workspace rather than a disposable one-off query.

Setup follows four steps: create an account, copy the API token from your dashboard, install the plugin and paste the token into a button. It runs on macOS 11 or later, on both Intel and Apple Silicon. The product is developed by Martijn Smit under the Lostdomain label and is licensed with a documented licence agreement, refund policy and terms of service. It is aimed at writers, developers, support staff and anyone who wants a consistent, quick AI workflow rather than ad-hoc prompting.

**Pricing & Plans:** Paid software purchased from the vendor, with a licence agreement and refund policy; discounts have been offered at checkout. See the official pricing page for current plans.

- **Process selected text with one key:** Select text in any app, press a key, and the AI processes it in place — no more copy-pasting into a chat window.
- **Custom prompts per button:** Every button can hold its own prompt; pick from the included examples or write your own for rewriting, translating, summarizing and more.
- **Better ChatGPT web interface:** Continue any conversation in the web app with folders, favourites, history search, message editing and prompt library.
- **Export, search and image generation:** Export chats, export screenshots, run Google lookups and generate images without leaving the conversation.

**Strengths:** Turns text processing into a single keypress in any application; Per-button custom prompts make repeated tasks consistent; Web app adds organisation ChatGPT lacks: folders, search, prompt library; Documented licence, refund policy and terms

**Limitations:** Requires a Stream Deck device and macOS 11 or later; Needs an account and an API token before any button works

## 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
