Caller vs Dokta

Browser-Based Calling

Discover the simplicity of calling without any software. Caller operates entirely within your web browser, be it on a computer, tablet, or smartphone. This eliminates the need for downloads, installations, or constant app updates. The experience is instant and uniform across devices, granting you the freedom to make a call from anywhere you have an internet connection, turning any device into an international calling hub in mere seconds.

Transparent Pay-As-You-Go Pricing

Embrace a model of true financial clarity. With Caller, you only pay for the minutes you actually use, with rates starting from just $0.02 per minute. There are no monthly subscriptions, no minimum fees, and no hidden charges. You simply add credit to your account, which never expires, and are billed precisely for your completed call time. This approach invites you to explore global communication without the burden of a financial commitment.

Global HD Voice Quality

Experience conversations as if you were in the same room. Caller is powered by enterprise-grade infrastructure dedicated to delivering high-definition audio quality on every call. This focus on clarity ensures that your important conversations with clients, loved ones, or support lines are free from distortion, lag, or dropouts, making distance feel insignificant.

Dedicated Virtual Phone Numbers

Curious about establishing a professional local presence abroad? Caller allows you to purchase your own dedicated phone numbers from countries like the US, UK, and Canada. You can choose from local, toll-free, or mobile numbers to use as your caller ID. This feature is perfect for businesses, freelancers, or anyone needing a separate contact line, providing instant credibility and convenience for international contacts.

Instant AI Document Analysis

Dokta's foundation is its lightning-fast AI analysis. Simply drag and drop any document—invoice, quote, contract—and within 60 seconds, the system automatically performs OCR and uses AI to classify the document type, extract critical data like amounts, due dates, and client details, and structure it all within your dashboard. This eliminates manual data entry, ensuring your financial records are accurate and up-to-date from the moment a document arrives.

Automated Invoicing & Online Quotes

Move beyond static PDF generators. Dokta allows you to create professional invoices and quotes in clicks. For freelancers on day-rate contracts, it can even automate monthly invoicing. A standout feature is the ability to send quotes with an online acceptance link; once a client approves, you can convert that quote into a finalized invoice with a single click, streamlining the entire proposal-to-payment workflow seamlessly.

Real-Time Cash Flow & Anomaly Detection

Gain immediate insight into your financial health with a clear, visual dashboard. Dokta tracks invoiced revenue, collected cash, outstanding payments, and VAT liabilities over a 12-month period. Beyond visibility, it acts as a guardian by detecting potential document anomalies, such as duplicate invoices, inconsistent VAT numbers, missing numbering, or suspicious changes to supplier IBANs, helping to protect your business from errors and fraud.

Intelligent Client Database & Payment Tracking

Dokta automatically builds and enriches your contact list from the documents you process, using SIRET numbers to pull in official business details. It assigns a payment score to each client based on history and enables automated, polite payment reminders for overdue invoices. This transforms your documents from isolated files into a dynamic network of client intelligence, helping you manage relationships and improve cash collection.

International Business Development

Sales and business development teams can leverage Caller to cost-effectively reach leads and partners across the globe. The ability to call landlines and mobiles in over 200 countries at a fraction of traditional cost removes a significant barrier to international expansion. Using a dedicated local number can also increase answer rates and project a professional, established image.

Remote Team Communication

For distributed teams with members in different countries, Caller provides a simple, unified tool for quick voice communication. Managers can connect with remote employees, or team members can collaborate without relying on varying local carrier plans or complex corporate systems, all while enjoying clear audio quality.

Personal & Family Connections

Individuals with family and friends overseas can maintain close relationships without worrying about exorbitant phone bills. The pay-as-you-go model is ideal for sporadic, longer catch-up calls, allowing users to stay connected affordably and reliably from the comfort of their browser.

Accessing International Services

Travelers, expats, or anyone needing to contact foreign banks, government offices, or customer support lines can use Caller to bypass expensive international roaming charges. It provides a reliable way to manage affairs abroad by calling local landline numbers directly, ensuring important calls can be made clearly and without hassle.

The Freelance Developer or IT Consultant

For freelancers working on Time & Materials contracts, administrative overhead is a distraction. Dokta automates the entire billing cycle: it can generate monthly invoices automatically based on the contract terms, track when they are paid, and send follow-ups for late payments. This allows the developer to focus purely on coding while ensuring their cash flow is managed proactively and professionally.

The Creative Project Freelancer

Graphic designers, writers, and other project-based creatives can streamline their client journey from pitch to payment. They use Dokta to create and send visually appealing quotes with online acceptance. Once approved, the quote becomes a billable invoice instantly. The platform then tracks the project's payment status, manages deadlines, and automates reminders, ensuring they get paid for their creative work without awkward conversations.

The Auto-Entrepreneur / Micro-Entrepreneur

Solo entrepreneurs under France's auto-entrepreneur regime need simplicity and compliance. Dokta helps by generating conforming invoices, tracking income against the URSSAF ceiling, and sending alerts for contribution deadlines. It provides a clear, real-time view of earnings and tax liabilities, eliminating guesswork and stress around declarations and helping them stay focused on growing their business.

The Growing Small Business

As a small business scales, document chaos can stifle growth. Dokta serves as a centralized command center for all financial documents—from supplier invoices to client contracts. It provides a unified view of cash flow, automates accounts payable/receivable tasks, flags financial discrepancies, and maintains a clean, exportable record for accountants, enabling better financial control and decision-making.

Caller operates on a flexible, credit-based system. You pay only for what you use with no monthly fees or subscriptions. International call rates start as low as $0.01 to $0.02 per minute to many destinations, which can be up to 90% cheaper than traditional carriers. Credits are added to your account in any amount you choose and never expire. Additionally, for users wanting a dedicated phone number (like a US or UK number), these are available as a separate monthly subscription starting from $1.99 per month. All pricing is transparent and detailed on their website, with charges applied solely for completed call minutes.

Dokta offers simple, transparent subscription plans without hidden modules. All paid plans include a 14-day free trial.

Do I need a phone or SIM card to use Caller?

This is where Caller redefines the norm: no, you do not. The service operates independently of your traditional phone line or mobile SIM. All you need is an internet connection and a device with a web browser (like Chrome, Safari, or Edge) and audio capabilities.

They adhere to a strict no-hidden-fees policy and do not require long-term contracts, prioritizing your privacy and trust.

How does Dokta's AI analysis work?

You simply upload a document (PDF, photo, or scan) to the platform. Dokta first uses Optical Character Recognition to read the text. Then, its AI engine, powered by Claude from Anthropic, classifies the document type and intelligently extracts key structured data like the total amount, due date, client or supplier name, and tax information. This entire process is completed in under 60 seconds, populating your dashboard with actionable information.

Is my data secure with Dokta?

Absolutely. Dokta prioritizes security and compliance. All data is encrypted using AES-256 standards. The platform is fully GDPR compliant, and its servers are hosted exclusively in Europe on Amazon Web Services in Paris. This ensures that your sensitive business and client data remains under strict European data protection regulations.

What happens if I exceed my document limit?

Dokta operates on a tiered subscription model based on the number of documents you can process per month. If you are on a paid plan and approach your limit, you will be notified. You can then choose to upgrade your plan to a higher tier with a larger document allowance to continue using the service uninterrupted.

Can I try Dokta for free?

Yes, Dokta offers a free "Découverte" tier to get started. This plan allows you to process up to 15 documents per month (with a 5-page maximum per document), use the free invoice generator, and maintain an unlimited client database without requiring a credit card. It's a full-featured trial designed to let you explore the core automation capabilities risk-free.
