## PDFgear

PDFgear targets the everyday PDF chores that usually push people toward paid subscriptions: editing text and images in a document, converting to and from Word, Excel or images, merging and splitting files, compressing large scans, filling forms and applying signatures. The core selling point is that these are available at no cost, with the software installed locally on Windows, macOS, iOS or Android, and a parallel set of browser tools for quick one-off jobs.

Where it differentiates is the AI layer. The built-in assistant can summarise a long PDF, answer questions about its contents and pull specific text out of tricky layouts — useful for research papers, contracts and reports where copy-paste fails. OCR converts scanned documents into editable Word or TXT in more than 30 languages. The editor itself aims to feel like a word processor, with support for annotating, highlighting, inserting shapes and reorganising pages.

The site also explains openly why the product can be free, describing its sustainability model, and it links to a related e-signing service. Because there is no account requirement for most operations and the desktop software runs offline, PDFgear suits users who are privacy-conscious or simply tired of upload limits. It is a strong general-purpose alternative to Adobe Acrobat for routine work, though highly specialised print or enterprise workflows may still need commercial tooling.

**Pricing & Plans:** Free. The desktop apps and online tools are offered at no cost, with no signup required for typical tasks. A related e-signing service is also available.

- **Full PDF editing:** Edit text, images, shapes, links, signatures and form fields in a document as easily as in a word processor.
- **AI assistant:** Chat with a PDF, generate summaries and extract answers or text from long and awkwardly laid-out documents.
- **Conversion suite:** Convert between PDF, Word, Excel, PowerPoint, TXT and images, including batch conversion with lossless output.
- **OCR in 30+ languages:** Turn scanned or image-based documents into fully editable Word or TXT files.
- **Cross-platform access:** Use native apps on Windows, macOS, iOS and Android, or dozens of browser tools with no installation.

**Strengths:** Genuinely free for both desktop and online use, with no account required for most tasks; AI assistant adds summarisation and document Q&A on top of standard editing; Available across Windows, macOS, iOS, Android and the web; OCR supports more than 30 languages for scanned documents

**Limitations:** Very large or highly specialised print workflows may still need commercial software; The number of separate online tools can be hard to navigate at first; AI features depend on document quality, so poor scans can produce weaker summaries

## 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
