## AIPRM

AIPRM installs as a browser extension and injects a prompt library directly into the ChatGPT and Claude interfaces. Instead of retyping the same instructions, you browse a catalog of thousands of prompt templates covering SEO, marketing, copywriting, sales, operations, and support, then apply one with a single click. The company says more than two million users and several large brands rely on it, and each template carries usage counts and community votes so you can judge quality before using it.

Beyond the public library, AIPRM is a prompt management system. You can save your own private prompt templates, organize them into custom lists, star favorites, hide prompts you never want to see, and control tone and writing style through selectors. A Power Continue feature extends the assistant's continue-writing button with expand, simplify, and shorten actions, and higher plans let you customize those actions yourself.

AIPRM also targets teams: multi-seat plans share a private prompt space so everyone uses the same vetted instructions, which helps keep brand voice and output structure consistent across a department or agency. Access is sold as a freemium extension with paid Solo and Team tiers, and the free version can be used indefinitely with lower quotas.

**Pricing & Plans:** Free tier available for unlimited time with lower quotas; paid Solo and Team/multi-seat plans add higher quotas, more private prompt templates and lists, and customization. FAQ pages reference roughly $10 for a Plus-level plan and about $33 for Pro, billed in USD with local sales tax added at checkout.

- **Curated prompt library:** Thousands of community and team-verified prompt templates across industries, each with usage counts and user votes so you can pick proven prompts rather than guessing.
- **Private prompts and custom lists:** Save your own templates for reuse, group them into named lists such as copywriting or legal, star favorites, and hide noise you never want to see again.
- **Team prompt sharing:** Multi-seat plans give a team one shared private prompt space, keeping instructions, tone, and output formats consistent across everyone's AI sessions.
- **Tone and writing style controls:** Selectors let you shift the tone and style of an answer without rewriting the prompt, and paid plans let you define your own custom tones.
- **Works inside ChatGPT and Claude:** The extension runs where you already work, adding the library, lists, and Power Continue actions to the assistant interface instead of a separate app.

**Strengths:** Large, actively maintained prompt library with community voting signals; Private prompt management turns one-off prompting into a reusable team asset; Runs inside ChatGPT and Claude, so there is no context switch; Free tier is usable indefinitely, making evaluation low risk

**Limitations:** Community prompts are not all team-verified, so quality varies; Value depends on using ChatGPT or Claude as your main assistant; Highest quotas and customization require paid plans; all sales are non-refundable

## Letty

Letty positions itself as an inbox productivity layer rather than a full email client. After installing the Chrome extension, it appears alongside your Gmail composition window and analyses the thread in front of you. From there it can propose a contextually relevant reply, draft a longer message from a short prompt, or help you match the tone of earlier messages in the chain. The goal is straightforward: cut the minutes you spend staring at a blank reply box.

What separates Letty from a generic writing assistant is the training step. You can feed it your own documents, an FAQ list, or the text of a website, and it will pull answers and phrasing from that material when it writes. The dashboard reports how many characters you have attached, which makes it practical for support teams or founders who answer the same questions repeatedly.

Pricing follows a freemium shape with a genuinely usable entry point. The Free plan gives 10 AI credits each month and room for up to 400,000 training characters. Paid tiers step up quickly: Premium adds 150 credits and up to 4 million characters, and Platinum lifts credits to unlimited with a 10 million character training allowance. Credits reset on the first of each calendar month. The platform is Gmail-only today, with Outlook and Zoho described as future additions.

**Pricing & Plans:** Freemium. A Free plan offers 10 AI credits per month and up to 400,000 training characters. Premium is $9/month for 150 credits and 4M characters, and Platinum is $19/month for unlimited credits and 10M characters. Annual billing discounts are available, and credits reset each calendar month.

- **Context-aware smart replies:** Letty reads the incoming thread and proposes replies that fit the conversation, helping you clear your inbox without writing every response from scratch.
- **One-click email drafting:** Turn a rough idea into a finished message. Letty drafts professional emails for pitches, follow-ups, introductions, and everyday correspondence.
- **Train on your own knowledge:** Attach documents, FAQs, or a website URL and Letty draws on that material to answer questions accurately in your replies.
- **Style matching:** Letty can mirror your tone and phrasing so outgoing mail sounds like you rather than a generic template.
- **Gmail-native extension:** Letty lives inside Gmail as a Chrome extension, so drafting and replying happen where you already work with no separate app to manage.

**Strengths:** Works inside Gmail, so there is no new inbox to learn; Training on your own documents or website produces more accurate, on-brand replies; Free tier lets you test the core workflow at no cost; Clear, tiered pricing with an unlimited-credit top plan

**Limitations:** Officially supports Gmail only; Outlook and other providers are listed as “coming soon”; Free tier is capped at 10 AI credits per month and modest training-character limits; Credit allowances reset on the calendar month rather than the billing anniversary; Advanced controls for style fine-tuning require effort before replies fully match your voice
