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.

The interface is deliberately simple — capture a thought, optionally categorise it, and it immediately joins your evaluation flow. The distinctive part is how evaluation works. Rather than scoring ideas once and moving on, sliiidea uses a swipe interface similar to popular dating apps: swipe right to upvote, left to downvote. Revisiting ideas regularly and evaluating them the same way builds a more reliable, less mood-dependent basis for deciding which ideas are worth pursuing. You can organise ideas in lists, filter them, track their status and mark the strongest ones as 'to implement' when it's time to choose. The app is free to use on iOS, Android and the web, with no account required to try it. The developers also list AI features on the roadmap — AI-generated idea lists from a description, AI-augmented ideas mixed into your list, automatic enhancements and feedback, and duplicate detection — which will strengthen the brainstorming side as they ship. **Pricing & Plans:** Free — sliiidea is free to use on iOS, Android and the web, with no account required to try it. - **Fast idea capture:** Capture thoughts instantly with a simple interface so nothing is lost; ideas drop straight into your evaluation flow. - **Swipe to prioritize:** Evaluate ideas like a dating app — swipe right to upvote, left to discard — for repeated, mood-independent judgment. - **Lists, filters and statuses:** Organize ideas in lists, apply filters and track status, then mark winners as 'to implement' when it's time to decide. - **Reflection over time:** Come back regularly, add new thoughts and let ideas grow and develop over time rather than stall after capture. - **AI features on the roadmap:** The roadmap includes AI-generated idea lists, AI-augmented suggestions, automatic feedback and duplicate detection. **Strengths:** Free to use across iOS, Android and web; Swipe evaluation makes prioritization fast and repeatable; Simple, focused interface avoids feature bloat; Roadmap promises AI-generated ideas and duplicate detection **Limitations:** AI features (auto idea generation, feedback, duplicate detection) are still listed as upcoming; Focused purely on idea capture and prioritization, not on executing projects; Requires regular revisits to get the most from the evaluation model [Profile (Markdown)](https://openaitools.app/tool/sliiidea.md) ## Frequently Asked Questions ### How do LightPDF and sliiidea compare in monthly traffic?
