Our Mission
The internet is full of information, forms, meetings, and decisions. Most AI tools ask you to leave your workflow and open a separate app. We think that's backwards.
Zenva AI lives where you work — in your browser tab. It sees the page you're on, understands the context, and helps you act immediately — without copying, pasting, or switching windows.
Everything Zenva AI Does
AI Chat
Ask anything about the page you're on. Summarise articles, extract data, translate, explain concepts — all without leaving the tab.
Smart Autofill
The AI scans any form and fills it using your saved profile — job applications, sign-ups, surveys — completed in seconds.
Requires BalanceMeeting Assistant
Join any online meeting and get a live transcript plus AI-generated summary with action items and key decisions — automatically.
Requires BalanceScreen & Game Guide
Share your screen and get real-time AI guidance. Perfect for games, tutorials, or any task where you need a second pair of eyes.
Document Memory
Upload your CV, portfolio, notes, or product docs. The AI reads them and references them in every answer it gives you.
Requires BalanceAI Memory
Tell the AI things to remember — your job, preferences, goals — and it carries that knowledge across every session, forever.
Requires BalancePowered by the Best AI Available
Zenva AI runs on Anthropic's Claude — one of the most capable, nuanced, and safety-focused AI models in the world. Claude understands complex instructions, handles long documents, and produces responses that are actually useful, not just technically correct.
We use Claude Sonnet for detailed tasks (autofill, document analysis, chat) and Claude Haiku for ultra-fast real-time responses (meeting transcription, game guide auto mode) — giving you the right tool for every job without sacrificing speed.
Context-Aware Intelligence
Every chat message includes up to 5,000 characters of visible page text, so the AI always understands what you're looking at — no copy-paste needed.
Two Models, One Experience
Claude Sonnet handles deep analysis tasks; Claude Haiku powers real-time features like live transcription and auto game guidance at low latency.
Safety-First by Design
Anthropic's Constitutional AI training means Claude refuses harmful requests and is resistant to prompt injection attacks from malicious web pages.
Privacy by Design — Not an Afterthought
Passwords are bcrypt-hashed
We cannot read your password under any circumstances. If you forget it, it must be reset — we cannot retrieve it.
JWT Tokens with Revocation
Authentication uses JWT tokens with a 7-day expiry and a server-side revocation blacklist — logging out truly invalidates your session.
Screenshots Never Stored
Screenshots taken by the Screen / Game Guide are sent to Claude AI for real-time analysis and immediately discarded. We store no images on our servers.
HTTPS Everywhere
All production traffic is encrypted with HTTPS/TLS. No plaintext communication between the extension and our API.
Export or Delete Any Time
You own your data. Export everything or permanently delete your account from the Settings dashboard — no friction, no dark patterns.
Zero Advertising
We make money from subscriptions, not your attention. No tracking pixels, no ad networks, no data brokers.

Pay-As-You-Go Credits — No Subscriptions
Zenva AI doesn't lock features behind a subscription tier. Every account works off a credit balance: every AI request (chat, autofill, meeting transcription, screen guidance) uses a small amount of credit based on the actual work it does. There's no monthly fee and nothing to cancel.
Start Free
New accounts get $0.50 in free credit automatically — enough to try every feature, no credit card required.
Top Up Anytime
When your balance runs low, top up from the Settings dashboard. Credits never expire and roll over indefinitely.
