## 2paste.io

2paste.io is a lightweight web app for people who live in chat windows and API consoles all day. Instead of scrolling back through old conversations or half-written notes to find that one reliable prompt, you store each template once, give it a name, and tag it so it can be found again in seconds. There is nothing to install; the whole workspace runs in a browser tab and syncs to your account.

The feature that does the heavy lifting is variable substitution. Any {{placeholder}} you type inside a prompt is detected automatically and rendered as an editable field. Fill the fields once and the preview updates live, so you can confirm the final wording before you paste it into ChatGPT, Claude, an email client, or anywhere else. A single Replace & Copy button applies every substitution and puts the result on your clipboard.

Around that core loop the app adds the housekeeping you would otherwise do by hand: color-coded labels, project grouping, starred favorites, full-text search, a Cmd/Ctrl+K command palette, and ten-step version history. The service is currently free under a Founder's Access program, with the stated intent that early users keep feature parity if paid plans are introduced later.

**Pricing & Plans:** Freemium

- **Automatic variable replacement:** Write prompts with {{variable}} placeholders and the app turns each one into an input field, then substitutes your values the moment you copy.
- **Labels, projects, and filtering:** Group prompts into projects and tag them with up to ten color-coded labels, then filter by label, project, date range, or starred status.
- **Keyboard-first workflow:** Generate with the N key, jump around with Cmd/Ctrl+K, arrow through the list, and paste the result without leaving the keyboard.
- **Version history:** Every edit is snapshotted and the last ten versions are kept so you can preview or roll back without losing earlier wording.
- **Import and export:** Move your library in as JSON and take it out as JSON, Markdown, or plain text whenever you want, with no vendor lock-in.

## 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
