## 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

## Thunderbit

Thunderbit is an agentic web scraper built for teams that need data out of websites but do not want to maintain selectors or write scraping code. It installs as a Chrome or Edge extension: open any page, click extract, and the AI reads the layout and proposes the fields that make sense — product names, prices, emails, phone numbers, listings, reviews, and more. You confirm or refine the request in plain English, and the agent returns a clean table with the rows you asked for.

For high-volume sites it offers two faster paths. Pre-built templates cover popular destinations such as Amazon, eBay, Google Maps, Zillow-style listing sites, social platforms, and directories, returning the same fields every time without consuming AI credits. Agent mode handles less structured work by following links from list pages into detail pages, pairing each result card with the information on its article or listing so research tasks that would normally take hours finish in one run. AI can also summarize, categorize, translate, or reformat data during extraction, and results export to Google Sheets, Airtable, Notion, Excel, CSV, or through the Web Scraper API.

The product is positioned mainly for sales, real estate, operations, and marketing teams. Typical uses include scraping contact information and turning directories into lead lists, tracking buying signals like hiring or funding changes, aggregating property listings, monitoring competitor prices and SKUs, watching stock availability, and gathering reviews for sentiment analysis. Pricing is freemium: a free-forever tier with limited credits, then Starter, Professional, and Business plans that scale credits and add priority support, with an API and custom enterprise terms available.

**Pricing & Plans:** Freemium. A free-forever plan provides a limited monthly credit allowance, and paid Starter, Professional, and Business plans scale credits and features (yearly billing saves around 20% with credits upfront). A Web Scraper API is available for developer integration, and Business offers custom credits, custom limits, and priority support at custom pricing.

- **One-click AI extraction:** Open a page, click extract, and AI proposes the fields worth capturing and returns structured rows — no CSS selectors or drag-and-drop setup.
- **Pre-built site templates:** For popular sites like Amazon, eBay, and Google Maps, pre-built templates return consistent fields instantly without spending AI credits.
- **Agent mode with linked pages:** Thunderbit can open linked pages and pull details from them, so a results list and its detail pages become a single table in one run.
- **AI data shaping:** Summarize, categorize, translate, reformat, or calculate fields as part of the scrape, so exports arrive ready to use.
- **Direct exports and API:** Send results directly to Google Sheets, Airtable, or Notion, export to Excel or CSV, or connect via the Web Scraper API for developer workflows.

**Strengths:** Works without CSS selectors or coding knowledge; Pre-built templates for popular sites save AI credits; Agent mode follows linked pages for deeper enrichment; Exports directly to Sheets, Airtable, Notion, Excel, and CSV

**Limitations:** Fully free usage is limited by monthly AI credits; Scraping some sites can be affected by anti-bot measures or site terms; AI field suggestions occasionally need refinement for complex or unusual page layouts; Best experience requires the Chrome/Edge extension rather than a fully browser-free workflow
