## 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

## Prompt Builder

Prompt Builder addresses a common friction in working with large language models: writing a prompt that actually produces the output you want. Instead of guessing at structure, you describe your idea and pick a target model, and the tool returns a complete prompt with roles, tasks and constraints filled in. Because it tunes output for the specific model you name, you spend less time retrofitting one prompt between ChatGPT, Claude, Gemini and Grok.

A second workflow handles prompts you already rely on. Paste an existing prompt into the Optimizer, and Prompt Builder analyses it, asks up to three quick clarifying questions, then rebuilds it stronger. You can also save reusable Instructions covering voice, context and constraints so those details are applied automatically to everything you generate, rather than being re-explained each time. Each refine is tracked on a timeline, so you can compare where you started and revert to any earlier version.

Beyond generation, the product acts as a lightweight workspace: a built-in chat lets you refine prompts and run them with models including Grok, Gemini, GPT and DeepSeek, and contextual follow-up suggestions offer variations after each build. Additional-context views show the assumptions the engine made, keeping the process transparent. It is designed for people who use AI for real deliverables — marketers, developers, analysts and researchers — rather than casual experimentation.

**Pricing & Plans:** Freemium. You can try it without an account and get 5 free prompts with no credit card. Paid access is offered as a Prompt Generator Lifetime deal (advertised at a launch price, e.g. $149 instead of $249); check the pricing page for current offers and features.

- **Model-specific prompt generation:** Describe your idea and choose a target model — ChatGPT, Claude, Gemini, Grok and more — to get a prompt structured for that model rather than a generic template.
- **Prompt Optimizer:** Paste a prompt you already use and the Optimizer analyses it, asks up to three clarifying questions and rebuilds a stronger, more complete version.
- **Reusable Instructions:** Save instructions for voice, context and constraints so they are applied automatically to every prompt you generate.
- **Versioning and follow-ups:** Every refine is tracked on a timeline for comparison and rollback, and contextual next-step suggestions keep the exploration going.
- **Run prompts inside the app:** A built-in chat workspace lets you refine and run prompts with models such as Grok, Gemini, GPT and DeepSeek without switching tools.

**Strengths:** Model-specific output removes trial-and-error between LLMs; Optimizer improves prompts you already rely on; Reusable Instructions and version history make prompts repeatable; Free to try with 5 prompts and no credit card

**Limitations:** Lifetime pricing is an upfront cost rather than a monthly subscription; Free usage is limited to a handful of prompts; The value depends on how much you use LLMs for structured work
