## 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.

## 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
