## GPTKeeper

GPTKeeper exists to solve one very practical problem: ChatGPT conversations are easy to lose, hard to reference later, and awkward to send to other people. The extension attaches itself to your ChatGPT session and adds straightforward controls for capturing a whole thread, exporting it as a PDF document, and generating a link you can hand to a colleague, classmate or friend.

Because it is distributed through the Chrome Web Store, installation is a one-click affair and no separate account is required. The extension is deliberately narrow in scope: it does not try to become a chat client, a prompt library or a knowledge base. Instead it behaves like a clipboard for your AI conversations, which makes it quick to learn and light on system resources.

The listing notes a modest user base and the interface text is mainly in Japanese, so it is best suited to Japanese-speaking users or anyone comfortable working with a simple, icon-driven toolbar. It handles website content in order to read the conversation you are currently viewing.

**Pricing & Plans:** GPTKeeper is free to install from the Chrome Web Store. No paid tier or subscription is listed.

- **One-click conversation saving:** Capture an entire ChatGPT thread without copying and pasting message by message.
- **PDF export:** Download the saved conversation as a PDF file that can be archived, printed or attached to an email.
- **Link sharing:** Generate a shareable link for a conversation so others can read it without a screen recording or screenshot.
- **Social network sharing:** Publish a conversation directly to networks such as Facebook or Twitter, or embed it on a website.
- **No account needed:** Runs as a browser extension with no sign-up, keeping the workflow to a couple of clicks.

**Strengths:** Very simple, focused workflow that takes only a few clicks; PDF export gives you a durable offline copy of a conversation; Free to install with no account or sign-up required; Small download size, so it barely affects browser performance

**Limitations:** Interface text is mainly in Japanese, which limits accessibility for other audiences; Last updated in 2023, so it may lag behind newer ChatGPT interface changes; Only useful to people already using ChatGPT in a Chrome-based browser

## LightPDF

LightPDF positions itself as an all-in-one document workspace rather than a single-purpose converter. The classic side of the product covers the essentials most people need every day: viewing and editing PDF text and images, converting between PDF and Office/image formats, OCR for scanned files, merging, splitting, compressing, watermarking, signing and annotating. Because everything runs in the browser with companion apps for Windows, Mac, iOS and Android, the same account and files travel with you across devices.

The AI layer is where the product has expanded most. An AI agent lets you chat with an uploaded document, ask follow-up questions and trace answers back to citations, while a separate chat experience works on YouTube videos. Document translation preserves the original layout across 20+ languages, including scanned and image-based PDFs, and structured data extraction turns invoices, receipts, bank statements and purchase orders into editable spreadsheets. Rounding out the suite are an AI PPT generator, mind-map and summary generation, watermark and sticker removal, text and logo erasing, document enhancement for scanned pages and an AI invoice generator.

Pricing follows a freemium model with a free tier (10MB file limit, watermark on some exports) and paid plans that add unlimited file sizes, batch processing, cloud storage and monthly AI credits. Individual subscriptions start around $5.99 per month, with a yearly option near $15.99 and a one-time lifetime plan; credits are consumed per AI action, so heavy AI users can top them up. Team, business and education plans are available on request.

**Pricing & Plans:** Freemium. A free plan covers basic PDF tools with a 10MB file cap; paid plans start around $5.99/month, with a yearly tier and a one-time lifetime option. AI features consume monthly credits that differ by plan.

- **AI document agent and chat:** Upload a PDF and ask questions in natural language, follow up on details and see which passages the answers came from. A separate chat mode works with YouTube videos.
- **Layout-preserving translation:** Translate whole documents, including scanned and image-based PDFs, into 20+ languages while keeping the original formatting and layout intact.
- **AI data extraction to spreadsheets:** Convert invoices, receipts, bank statements and purchase orders into structured, editable Excel files automatically.
- **Full PDF editing and conversion suite:** Edit text and images, OCR scanned pages, convert to and from Office formats, then merge, split, compress, watermark, sign and annotate.
- **Cross-platform access:** One account works on web, Windows, Mac, iOS and Android, so documents and paid features follow you between devices.

**Strengths:** Very broad toolkit that covers both everyday PDF chores and advanced AI document tasks; Free tier is usable for light jobs, and the paid plans are cheaper than many competing PDF editors; Layout-preserving translation and AI data extraction handle scanned documents that trip up simpler tools; One subscription covers five platforms, including desktop and mobile apps

**Limitations:** Free plan caps files at 10MB and adds watermarks on some outputs; AI features run on a credit system, so heavy usage means top-ups or a higher tier; Advanced AI operations like text editing or logo removal consume credits quickly
