## Comment Generator

Comment Generator tackles a very specific problem: commenting consistently enough to grow a social presence without sounding like a bot. Instead of producing generic one-liners, the extension reads the caption of the post in front of you and drafts a reply grounded in that specific content, which is why the results sound more like a person and less like a template.

Setup takes about a minute. You install the extension from the Chrome Web Store, sign up with an email address to activate a free trial, and then tell the tool how you write: your own instructions, preferred tone and the objective of a given comment, such as agreeing, disagreeing or adding insight. From then on, each draft appears alongside the post for you to accept, tweak or discard.

One design choice worth noting is that the extension never needs your platform credentials. It works as a layer on top of the site, and it always leaves the final action to you. The site also notes that comments are drafted in the language of the original post, so it works for languages beyond English. Paid plans and a developer API sit alongside the free trial.

**Pricing & Plans:** A 7-day free trial with no credit card is offered, after which paid plans apply. Pricing and API terms are listed on the site's pricing page.

- **Caption-aware drafting:** The extension reads the specific post before writing, so drafts reflect that content instead of a generic template.
- **Custom voice instructions:** Tell it how you write and it aims for your tone or your brand's tone rather than a neutral AI register.
- **Objective and tone controls:** Choose what the comment should do, such as agree, disagree or add insight, and how it should sound.
- **No account access required:** It works as a browser extension layered on the platform and never asks for your login credentials.
- **Multi-language support:** Comments are drafted in the language of the post, so it fits multilingual feeds.

**Strengths:** Grounds drafts in the actual post caption rather than generic phrases; Learns your voice through custom instructions instead of default AI tone; Never requires your social account login credentials; Supports Instagram, LinkedIn and Threads, with multi-language drafting

**Limitations:** It drafts but does not post, so it still requires your time on every comment; Works only in supported browsers as an extension, not as a standalone app; Free usage is limited to the trial window

## 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
