## Dropbox Sign (HelloSign)

HelloSign is the former name of Dropbox Sign. After Dropbox acquired the company, the helloSign.com domain now redirects to Dropbox's signing product, and the service continues under the Dropbox Sign brand with the same core purpose: replacing print-sign-scan with a clean digital workflow.

The product covers the full agreement lifecycle. You start with a document from Dropbox or another connected app, add signers, fields and a personalized message, then send it. Recipients review and sign securely with no account required, and completed documents can be saved automatically to your preferred storage. Templates let recurring documents — NDAs, offer letters, sales contracts — be prepared once and reused, while audit trails record who signed and when.

Beyond signing, Dropbox Sign integrates with Dropbox, Google Drive, Salesforce, OneDrive and other everyday tools, and a separate API lets developers build branded, secure signing directly into their own site, app or customer experience. Dropbox Fax, sold alongside it, sends faxes without a fax machine. The platform claims enterprise-grade security and a 4.7/5 rating on G2, and it positions itself on simplicity and speed of adoption rather than heavy configuration.

**Pricing & Plans:** Dropbox Sign starts a 30-day free trial that can be cancelled anytime. eSignature plans start at $15 per user per month billed yearly, while the API is sold separately starting at $75 per 50 requests per month billed yearly. Custom pricing is available through sales for larger organizations.

- **Account-free signing:** Recipients can review and sign agreements securely without creating an account, which removes friction from external signing.
- **Reusable templates:** Prepare NDAs, offer letters and contracts once, then reuse them for future requests to save time on recurring paperwork.
- **Signing API:** Embed secure, branded eSignature flows directly into your website, app or customer experience with a dedicated API.
- **Automatic document storage:** Completed agreements are saved automatically to your preferred storage account so nothing gets lost in inboxes.
- **Electronic fax:** Dropbox Fax sends faxes online, useful for industries still relying on fax for regulated documents.

**Strengths:** Legally binding eSignatures in the US, EU, UK and many other countries; Recipients sign without needing an account; Integrations with Dropbox, Google Drive, Salesforce and OneDrive; Automated audit trails and document storage

**Limitations:** Now branded as Dropbox Sign, which can confuse people looking for HelloSign; The API is priced separately from the core signing plans; Per-user subscription pricing adds up for large organizations

## 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
