## Duck.ai

Duck.ai brings the privacy philosophy behind DuckDuckGo's search engine and browser to conversational AI. You can chat with a range of popular AI models from a clean web interface, with no account required, and the company's stated goal is to keep your prompts from being linked to your identity or used to build an advertising profile.

The service is deliberately positioned as a low-friction entry point to AI: no app to install, no subscription, and no personal details to hand over before you can ask a question. For people who are uneasy about their chat history sitting inside a mainstream AI account, Duck.ai offers a simpler alternative that behaves more like a private search box than a social profile.

It sits alongside DuckDuckGo's broader privacy toolkit, which includes tracker blocking, cookie prompts management, email protection, and browsing protections, so users already invested in that ecosystem can add AI chat without introducing a new set of trackers.

**Pricing & Plans:** Free to use, with no account required. No paid tier is advertised for the chat service itself.

- **Multiple AI models:** Choose among several leading AI assistants from a single interface instead of juggling separate apps.
- **No account needed:** Start chatting without signing up, handing over an email, or creating a profile.
- **Privacy-first handling:** Chats are designed to stay detached from your identity rather than being tied to an ad profile.
- **Integrated in DuckDuckGo:** Accessible alongside the search engine and browser that already block trackers and cookie pop-ups.
- **Browser-based:** Works in the browser on desktop and mobile with no install step.

**Strengths:** Free with no signup required; Backed by DuckDuckGo's established privacy reputation; Several leading models in one place; Fits naturally with existing DuckDuckGo tracker blocking

**Limitations:** Fewer power-user features than dedicated AI apps; Conversation history and memory features are intentionally limited; Model selection and availability can change over time

## 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
