ZapKitt is a collection of 110+ free AI-powered tools. Build ATS-optimized resumes, compress PDFs, generate images, write emails, create business plans, and more. What makes it different: every tool is 100% free with no signup, no watermarks, no daily limits. File tools process everything in your browser — your PDFs, images, and documents never get uploaded to any server. AI writing tools are powered by Llama 3.3 70B. Built for students, job seekers, freelancers, and small businesses worldwide.
Quick update for the PH community! Based on feedback, here's what I shipped this week:
- PDF download now works instantly (client-side, no server wait)
- Resume builder generates all 14 sections with real metrics
- Interview prep generates 50 questions with detailed STAR answers
- Added Ko-fi support page for those who want to help keep it free
I'm building in public and would love your input — what tool should I prioritize next?
1. LinkedIn Profile Optimizer
2. Resume Tailoring (match resume to specific job description)
3. Portfolio Website Generator
4. Salary Negotiation Coach

With Llama 3.3 70B powering the writing side, how are you covering the compute costs on your end and still keeping everything genuinely free with no signup?
@yaar89286282857 I was thinking the exact same thing. How can you provide free LLM access?
Looked at the website and they claim to have over 12.5K users and over 250K AI generations and their provider claims to charge $0.59/M input and $0.79/M output tokens.
@yaar89286282857 @yudhish_khatri Great observation! Let me break down the real math:
Those 250K generations include ALL tool usage — not just LLM calls. PDF conversions, image tools, text formatting etc. run 100% client-side in your browser (zero server cost).
For the AI-powered tools (resume builder, interview prep), I use Groq's free tier (Llama 3.3 70B) which gives generous rate limits. Gemini's free tier and OpenRouter are failover backups. Multi-key rotation distributes load across accounts.
The actual LLM-heavy usage is a fraction of total generations. Most users generate 1-3 resumes then move on — it's not like a chatbot with ongoing conversations burning tokens.
Hosting: Vercel free tier. Domain: ~$10/year. Monthly cost right now: practically $0.
Will it stay free forever? If it scales to 100K+ active users hitting AI tools daily, probably not. But I'll add optional donations (Buy Me a Coffee) and a generous free tier before any paywall. The goal is keeping the core tools free and accessible.
@yaar89286282857 Great question! Right now I'm using Groq's free API tier which gives generous limits for Llama 3.3 70B. For failover I use Gemini's free tier and OpenRouter. The PDF/image tools cost nothing because they run entirely in your browser — zero server cost. Hosting is Vercel's free plan. Total monthly cost: $0. If usage grows beyond free tiers, I'll add optional donations (Buy Me a Coffee) before ever adding paywalls. The goal is keeping it free as long as possible.
Finally tried the resume builder and it actually pulled decent keywords from my old PDF without making me sign up. Also nice that the PDF tools stay local in the browser.
@erkanve9o Thanks for trying it, Erkan! Really glad the keyword extraction worked well from your PDF. That's exactly the use case I built it for — take an existing resume, pull out the right keywords, and restructure it for ATS. The local PDF processing was a deliberate choice — privacy shouldn't be a premium feature. If you have any suggestions for improvements, I'm all ears!
