It runs entirely in the browser: you choose files or a folder with the plus button, review the list, and start the upload while the progress indicator tracks the actual bytes sent. Once the transfer completes you register or sign in — via Google or an email code — to unlock your share link, and the recipient needs no account at all. The service is designed for handing over photos, finished videos and documents. Folder uploads preserve relative paths, so recipients can either grab individual files or hit "Download all" for a single ZIP that keeps the folder structure; empty folders are not retained. Supported previews include common images, PDF, browser-playable video and audio, and text, while Office and OpenDocument previews depend on an available conversion service and are capped at 64 MiB for the original file. The limits are clearly published rather than hidden behind a paywall: one transfer can hold up to 10 GB across 1 to 1,000 files, anonymous uploads stay available for 24 hours from creation, and signing in can extend an owned upload to 72 hours from the original creation time. Once a transfer expires the link stops working and background cleanup removes the originals, previews and unfinished upload parts. Files are stored on Cloudflare R2. **Pricing & Plans:** Free to use — the site publishes no paid tier, no subscription and no per-transfer fee for the documented 10 GB / 1,000 file limits. - **Large transfers up to 10 GB:** Send up to 10 GB in a single transfer, with support for 1 to 1,000 files per upload. - **Folder uploads without zipping:** Choose a folder directly in a browser that supports folder selection; relative paths are preserved so recipients get the structure back as a ZIP. - **No account needed for recipients:** Upload first, then sign in with Google or an email code to unlock the link — anyone with the link can download without registering. - **In-browser previews:** Recipients can preview common images, PDF, playable video and audio, and text before downloading, with Office/OpenDocument previews when the conversion service is available. - **Transparent expiry rules:** Anonymous transfers expire 24 hours after creation; a verified sign-in can extend an owned upload to 72 hours from its original creation time. **Strengths:** Free with a genuinely large 10 GB ceiling and no account required to upload; Folder uploads keep their structure, so recipients do not have to reassemble anything; Recipients never need to register, which removes friction for one-off transfers; Published, explicit limits and expiry behaviour instead of vague fine print **Limitations:** Retention is short — 24 hours anonymous and 72 hours signed in — so it is not long-term storage; Anyone holding a valid link can download before expiry, so links must be shared carefully; Office and OpenDocument previews depend on a conversion service and are limited to 64 MiB originals [Profile (Markdown)](https://openaitools.app/tool/drop.md) ## 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 [Profile (Markdown)](https://openaitools.app/tool/sider.md) ## Frequently Asked Questions ### How do DROP and Sider compare in monthly traffic?
