## Mochii

Mochii focuses on the moment you are actually working on the web. Instead of copying text into a separate chat tool, you open a sidebar that can see the page you are on, answer questions about it, summarize long documents, and draft replies. The extension is available for Chrome and Edge, and the same account works through a standalone web app on desktop and mobile, so your characters, memories, and knowledge base travel with you.

Beyond a standard chat box, Mochii leans into personalization. You can build custom AI characters tailored to specific jobs — a coding mentor, a writing coach, a data analyst — and give them persistent memories so they remember context from earlier conversations. A built-in knowledge base lets you upload your own material and query it, while a no-code chatbot builder turns that material into an embeddable assistant for a website.

Pricing is tiered by token allowance. A free Personal plan covers light daily use, while Pro, Premium, and Ultimate plans scale up monthly tokens, response speed, early access to new models, and options like custom model keys. Because Mochii aggregates third-party models, it is an independent product rather than an official offering from any single AI lab.

**Pricing & Plans:** Freemium. A free Personal tier includes a monthly token allowance with community support. Paid plans start at $4.99/month (Pro), $9.99/month (Premium), and $29.99/month (Ultimate), each with larger token pools, faster responses, early access, and advanced customization; yearly billing lowers prices by up to 20%.

- **Multiple AI models in one place:** Switch between OpenAI, Claude, Gemini, and image models like DALL-E and Stable Diffusion inside one unified sidebar instead of juggling multiple subscriptions and tabs.
- **Intelligent reading and analysis:** Analyze and summarize PDFs, images, and webpages directly, extracting key insights from documents and live pages as you browse.
- **Custom AI characters and memories:** Design reusable AI characters with their own roles, tone, and context, such as a developer, writer, analyst, designer, or tutor.
- **Knowledge base and chatbot builder:** Organize documents and notes into a personal knowledge system that the assistant can reference for grounded, context-aware answers.
- **Smart form filling and deep research:** Automate form filling, run deep research with citations, and get AI help with writing, coding, and business tasks across the web.

**Strengths:** Combines several top-tier AI models in one interface, reducing subscription sprawl; Sidebar extension works on any webpage, alongside PDF and image analysis; Custom characters, memories, and a knowledge base add useful personalization; No-code chatbot builder with lead generation and analytics

**Limitations:** The free tier is token-limited and better suited to occasional rather than heavy use; Advanced model access and custom API keys are locked behind paid tiers; Because it aggregates third-party models, availability can shift with upstream providers; Premium pricing can add up if you rely on high-volume monthly usage

## Syncia - Power of ChatGPT on any website

Syncia is a browser extension that injects an OpenAI-powered assistant into every web page you visit. Press Ctrl+Shift+X (or your own shortcut) and a sidebar opens where you can ask questions about the page, request rewrites, or brainstorm, all without switching tabs or copying content into a separate chat window. Because it works on top of the current tab, the assistant can be used directly on articles, documentation, emails, forums and web apps.

The second core piece is the selection menu. Highlight any passage of text and Syncia shows a small floating toolbar that can summarise it, simplify the language, translate it, check grammar, or adjust length. You can also save your own custom prompts and re-use them from that same menu, which turns favourite instructions into one-click actions.

Syncia is fully free and open source, published under the developer's GitHub repository. It does not ship a bundled model or subscription: you connect your own OpenAI API key, so you control the account, the spend and the data flow. Settings are handled on a dedicated configuration page, and the extension declares that it does not collect or sell user data.

**Pricing & Plans:** Free and open source. There is no subscription or paid tier; you supply your own OpenAI API key and pay OpenAI for the usage you generate.

- **Chat sidebar on any site:** Open an OpenAI-powered chat panel over the page you are browsing using a keyboard shortcut, so you never lose context.
- **Selection quick menu:** Highlight text to summarise, simplify, translate, check grammar, or change length from a floating toolbar under the selection.
- **Custom prompt library:** Save your own instructions as reusable prompts and trigger them from the quick menu in one click.
- **Bring your own API key:** Connect a personal OpenAI key for full control over the account, model choice and usage costs.
- **Open source and private:** The code is published publicly, the extension is free forever, and the developer states that no user data is collected or sold.

**Strengths:** Completely free and open source, with no paywall or bundled subscription; Works on virtually any website through a sidebar plus a selection toolbar; Custom prompt storage turns repeated instructions into one-click actions; Your own API key means full visibility and control over usage costs

**Limitations:** Requires a separate OpenAI API key and an OpenAI account before it is useful; Feature depth and model quality depend entirely on the OpenAI models you choose; Chrome-only, so Firefox, Safari and Edge users are not covered
