Inspiration

During document-heavy tasks, like reviewing legal files, reports, or academic papers, we realized how overwhelming and time-consuming it can be to extract key information — especially for visually impaired users or multitaskers.

We wanted to build a tool that lets you talk to any document and get an instant voice response, as if the document were alive and speaking to you. That idea gave birth to VocalDocs AI.

#What It Does VocalDocs AI is a no-code web app built entirely on Bolt.new that allows users to:

📄 Upload a document (PDF, Word, or plain text)

❓ Ask any question about the document’s content

🤖 Get an AI-generated answer

🔊 Listen to the response in a natural, realistic voice using ElevenLabs

Bonus: You can even translate the answer or generate a video summary using other tools.

How We Built It

The entire project was built on Bolt.new, using the no-code tools and HTTP request modules provided by the platform.

We integrated the following APIs:

Dappier / OpenAI – for natural language processing and document Q&A

ElevenLabs – for realistic text-to-speech audio responses

Lingo (optional) – to translate answers into multiple languages

Tavus (optional) – for video generation from AI-generated responses

All logic flows, user interface, and data handling were configured using Bolt's visual editor and backend tools.

Challenges We Faced

Document parsing: Extracting clean text from various file formats was tricky with limited native support. We had to rely on external APIs and pre-process text smartly.

Bolt-only constraint: Building exclusively within Bolt forced us to be creative with how we chained API calls and managed state.

Voice playback: Ensuring smooth playback of generated audio from ElevenLabs required caching and handling URLs carefully.

Rate limits: Managing API keys and staying within usage quotas during development was challenging but helped us optimize calls.

What We Learned

How to design and build a full product using no-code tools only

Efficient API orchestration in a visual interface

Real-world usage of AI tools like ElevenLabs and OpenAI

Balancing UX/UI with functional constraints

What's Next

Support for long documents and summarization

Voice input (not just output)

User accounts and history of previous Q&A

Improved accessibility for low-vision users
