## AIDEA

AIDEA is a small, focused browser extension for people who talk to AI models all day and are tired of retyping the same instructions. Instead of keeping prompts in a notes app and copying them by hand, you build a searchable library inside the browser and drop any saved prompt into a chat when you need it. The extension shipped on the Chrome Web Store in late 2023 and is offered by an independent developer at no cost.

The second half of the idea is customisability. AIDEA lets a saved prompt ask for input before it runs, so a single template can be reused with different topics, tones, or audiences instead of being rewritten each time. The developer also publishes SPARK, a custom GPT that walks you through assembling a prompt piece by piece, which is handy when you have a goal but not the wording.

Because it lives in the browser rather than inside one specific chat product, AIDEA is best understood as a companion layer for prompt-heavy work: research, writing, support replies, and repetitive operational tasks. It is deliberately lightweight — the listing is under 30 KB — and the developer states that no user data is collected or sold.

**Pricing & Plans:** Free. AIDEA is published as a no-cost Chrome extension with no paid tier listed.

- **Personal prompt library:** Store the prompts that work and pull them back up later instead of rewriting the same instructions from memory.
- **Customisable, input-driven prompts:** Settable templates can request input from you at run time, so one saved prompt covers many situations.
- **SPARK custom GPT:** A companion GPT that helps you construct new prompts step by step when you know the goal but not the phrasing.
- **Task automation shortcuts:** Reusable prompts shorten repetitive AI chores such as drafting, summarising, and templated replies.
- **Minimal, privacy-minded footprint:** A tiny browser extension whose developer declares that data is not collected, sold, or used for unrelated purposes.

**Strengths:** Genuinely free browser extension with no paywall to test; Prompt library and templates live where you already work — in the browser tab; Input-driven prompts make one saved prompt far more reusable; Very small install with a stated no-data-collection policy

**Limitations:** No public ratings or reviews yet, so quality signals are limited; Last listed update was December 2023, so newer AI features may not be mirrored; Tied to Chrome, so Firefox and Safari users cannot install it

## 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
