HoloChart How it works Privacy Pricing English English Deutsch Español Français Italiano Português 中文 日本語 한국어 Русский العربية Install free 100% on-device · cross-LLM See the answer. Not the wall of text. HoloChart projects any LLM's answer into an instant, living chart — ChatGPT, Claude, Gemini, Mistral, Perplexity and local Ollama. It assembles on your screen as the model types, entirely on your device. Even the share watermark doesn't track you. Install free → See it work No data leaves your browser · no second LLM · no telemetry · no ads, ever HoloChart live · on-device LIVE Bottom line Nautilus leads monthly revenue — 63% of total, 1.7× the runner-up. 31,400 18,600 0 Nautilus Team Free 100% local · no data leaves the browser · no second LLM Reads the answer on: ChatGPT Claude Gemini Mistral Perplexity Ollama / Open WebUI Before → after Watch the chart assemble itself. A rule-based, on-device visualizer — not an AI system itself. It reads the structure inside the answer and draws the clearest chart, live as it streams. The answer, raw Here is how the three plans compare by monthly revenue: | Plan | Monthly revenue (EUR) | | ---- | --------------------- | | Free | 0 | | Nautilus | 31,400 | | Team | 18,600 | Nautilus is clearly the biggest driver. HoloChart, live Bottom line Nautilus leads monthly revenue: 63% of the total, 1.7× the runner-up (Team). 31,400 18,600 0 Nautilus Team Free holochart.app 100% local · no data leaves the browser · no second LLM Capabilities One panel. Every model. Zero egress. Live as it streams The HoloGlass panel assembles while the model is still typing — bottom-line first, chart refining in real time. Structurally private Zero network calls with your content — verified by a no-egress build gate. Zero extension telemetry, no tracking pixel. Not even in the watermark. Works on local models The only AI-answer visualizer that also works with local Ollama — cloud artifact features cannot access your local instance. Speaks your language Auto-configures at install; switch language live and the result — numbers, currency, even RTL — updates instantly. One-click share Export the chart as PNG/SVG. The branding travels with it — turning every share into a quiet referral. EU-clean by design GDPR-clean by construction; under the EU AI Act it's a rule-based visualizer of third-party output, not a provider of an AI system. Architecture, not a setting Privacy isn't a toggle. There's nothing to toggle off. Your prompts and the model's answers never leave the page — there is no server to send them to. No second LLM Detection is rule-based and local. We never send your text to another model to "understand" it. No telemetry Usage counters (like trigger-rate) live only in your browser's local storage, surfaced only to you. Tracking-free watermark The share watermark is static shapes and text — no pixel, no ID, no callback. Fair · no ads · bootstrapped Free is genuinely free. Nautilus is the polish. All LLMs are free, forever. Nautilus removes the watermark, adds history, exports and multi-device. Free €0 All LLMs · watermark Nautilus €7 /mo no watermark · history · export Team €29 /mo per seat Lifetime €99 Nautilus forever · capped 300 🔥 Founder-Lifetime — Nautilus forever, no subscription ever, one-time €99 · 247  / 300 spots left — then subscription only.

DOM selectors for each LLM are kept up-to-date with each site change. Good questions Everything, answered. Does HoloChart send my prompts anywhere? No. Detection and rendering happen entirely in your browser. There are zero network calls with your content — enforced by a build-time no-egress gate. The only optional network call is a license check for Nautilus, which never includes your content. Is HoloChart an AI system under the EU AI Act? No. HoloChart is a rule-based visualizer of another model's output — it does not itself perform inference or generate content. It's GDPR-clean by construction. Which LLMs are supported? ChatGPT, Claude, Gemini, Mistral, Perplexity, and local Ollama / Open WebUI. All of them are available on the free tier; Nautilus removes the watermark and adds history, exports and multi-device. Why does it work on local models when cloud tools don't? Because HoloChart runs on-device and reads the rendered answer in your browser. Cloud "artifacts" features can only see content inside their own product — they can't reach your local Ollama. What does the watermark contain? Only the static text "holochart.app" and our logo tile — no tracking pixel, no unique ID, no network callback. Nautilus removes it entirely. HoloChart — See the answer. 100% local.

Your prompts and the model's answers never leave your browser. The extension itself runs no analytics and sets no tracking. This website uses Google Analytics only with your explicit consent (opt-in cookie banner). The only other network request is a license check for paid plans — it never contains your content. 1. Who we are (data controller) HoloChart is offered by AVAA Marketing Ltd , Alexander Ratter, Polykarpou Smyrnis 6, 4044 Germasogeia, Cyprus — a privacy-first browser extension that visualizes LLM answers locally. Contact: info@avaa.agency , +49 30 2096 5233. German version: Datenschutzerklärung . 2. What we process — and where When you use a supported LLM website (ChatGPT, Claude.ai, Gemini, Mistral, Perplexity, DeepSeek, Grok, Copilot, Poe, HuggingFace, Qwen/Tongyi, Kimi, Baidu Ernie, Google AI Studio, Meta AI, local Ollama/Open WebUI, and others), the extension reads the visible answer text in your browser to detect tables, JSON, and comparisons and render a chart. This processing is: Local only — it happens in the page, on your machine. Rule-based — no second LLM, no AI inference, no external service. Not transmitted — there are zero network calls containing your content. This is enforced by an automated build-time "no-egress" gate. 3. What we store Local preferences (e.g. language, tier) in your browser's storage.local . Never uploaded. Local usage counters (e.g. how often a chart was offered) in storage.local , shown only to you in the popup. We never receive them. License key (paid plans only), stored encrypted at rest in your browser. 4. The only network requests For Nautilus / Team plans, the extension contacts our license server ( api.holochart.app ) to validate your key and entitlement. This request contains the license key and plan identifier — never your prompts, answers, or any content . Legal basis: Art. 6(1)(b) GDPR (performance of contract). Payments are processed by Paddle.com Market Ltd. (UK) as Merchant of Record; we never receive your card details. The transfer to the UK is covered by the EU–UK adequacy decision. 5. Sub-processors Paddle.com Market Ltd. (UK) — payment processing and invoicing as Merchant of Record. Webgo GmbH (Germany, EU) — web and license server hosting. A data processing agreement under Art. 28 GDPR is in place. Google Ireland Ltd. (Ireland, EU) — website analytics via Google Analytics 4, used only with your consent (Art. 6(1)(a) GDPR). Data transfers to third countries are covered by EU Standard Contractual Clauses. Privacy policy: policies.google.com/privacy. 6. Retention License data (key, plan, activation date) is retained for as long as the license is active, and thereafter for the statutory bookkeeping retention period (typically 7 years), after which it is deleted. Local browser data (preferences, counters) stays on your device and is fully removed when you uninstall the extension. 7. Website Analytics (Google Analytics) This website uses Google Analytics 4, a web analytics service by Google Ireland Ltd. (Gordon House, Barrow Street, Dublin 4, Ireland). The service is activated only with your explicit consent (opt-in cookie banner, Art. 6(1)(a) GDPR). Google Analytics uses cookies to analyse how you use the site (pages visited, time on site, approximate location). IP anonymisation is enabled. No user profile is linked to personal identifiers, and no remarketing takes place. Before you consent, no Google script is loaded and no contact is made with Google servers. With your consent, GA4 sets the cookies _ga (distinguishing unique visitors, 2 years) and _ga_FGXSCKQ2FH (session state, 2 years). Legal basis: Art. 6(1)(a) GDPR (consent). Withdrawal: you can withdraw your consent at any time via the “Cookie settings” link in the footer of every page — the banner will reappear and you can choose “Decline”; existing GA cookies are removed. Alternatively, clear the hc_cookie_consent key from your browser's localStorage . More information: policies.google.com/privacy · GA opt-out add-on . 7a. Launch waitlist If you join the launch waitlist (on this website), we process your e-mail address for the sole purpose of notifying you about the launch and delivering the announced founder offer. The address is stored on our own server (hosted by Webgo GmbH, Germany, EU); a one-off confirmation e-mail is sent via the e-mail delivery service Resend (Resend, Inc., USA — transfer covered by EU Standard Contractual Clauses) or our own mail server. Legal basis: Art. 6(1)(b) GDPR (steps prior to entering into a contract, at your request). The address is deleted after the launch notification has been sent, or earlier if you unsubscribe — simply reply with “unsubscribe” or e-mail info@avaa.agency . No newsletter, no marketing list. 8. What we do NOT do No analytics or telemetry in the extension . The extension never sends usage data. No fingerprinting, no advertising, no selling or sharing of data. No tracking in the share watermark — it is static text and a logo, with no pixel, ID, or callback. Website analytics (Google Analytics) only after your explicit opt-in consent — see section 7. 9. Your rights (GDPR) You have the right of access, rectification, erasure, restriction, portability, and objection (Arts. 15–22 GDPR). Because we hold very little server-side data, requests typically concern the license record for paid plans. Contact: info@avaa.agency . You also have the right to lodge a complaint with a supervisory authority. As a Cyprus-incorporated company, our lead supervisory authority is the Commissioner for Personal Data Protection , 1 Iasonos Street, 1082 Nicosia, Cyprus ( www.dataprotection.gov. ------------------------------------------------------------
