Jelluvi

Open-source, local-first browser extension for exporting the AI chat conversation currently open in your browser to local files.

The extension is designed around no telemetry, no analytics, no remote rendering, no external export servers, no remote hosted code, and minimal Manifest V3 permissions.

No account is required to use Jelluvi. The extension operates on the supported AI chat page already open in your browser.

Brand and Theme

• Product name: Jelluvi.
• Icon source: assets/brand/jelluvi.png.
• Runtime surfaces use generated 128px/512px derivatives so the canonical 1200px source is not shipped on every popup or landing-page load.
• Primary action and focus color: #005FEF in the light theme.
• Brand accent color: #00C6FF.
• Light theme uses a clean white background and neutral slate text.
• Dark theme uses a dark navy or near-black background with readable slate text.
• Core exports remain local-first with no telemetry, no server uploads, no remote rendering, no external fonts, and no remote hosted code.

Supported Platforms

• ChatGPT at https://chatgpt.com/* and https://chat.openai.com/* is stable.
• Claude and Gemini are beta visible-message adapters with documented limitations.
• Perplexity and NotebookLM are experimental visible-message adapters until real live QA passes.

For current adapter status and live QA criteria, see Provider QA Checklists.

This project is not affiliated with, endorsed by, or sponsored by OpenAI, Anthropic, Google, Perplexity, or any AI platform.

Supported formats

• Markdown .md
• TXT .txt
• JSON .json
• CSV .csv
• HTML .html
• PDF .pdf
• DOCX .docx
• PNG snapshot .png
• ZIP bundle .zip

Markdown profiles are available for default archives, Obsidian, GitHub, GitBook, and research logs.

Extension workflow

• The popup contains only provider status, format choices, Export, Copy MD, Preview, and transient preparation controls. There is no manual Scan button or Options drawer.
• Export, Copy MD, and Preview prepare or refresh the local snapshot automatically.
• Preview provides provider-neutral all, selected, user, assistant, and range views. The current prepared view can be downloaded, copied, opened as PDF, or saved to the opt-in Local Library.
• Settings contains persistent export, content, PDF, privacy, library, and batch controls. Support and product documentation remain on GitHub and the website.

Provider metadata, origins, support levels, limitations, and capabilities are defined in one catalog. See Provider architecture.

pnpm check runs lint, typecheck, unit tests, and a production build.

Support and Business Model

Core exports stay free and open-source. Jelluvi does not add ads, telemetry, branding in exports by default, feature lockouts, or pricing gates around the core local export workflow.

Support channels:

• GitHub Sponsors: https://github.com/sponsors/voropaevv

Business model:

• Donations support maintenance, docs, provider fixtures, and compatibility updates.
• Paid support can cover setup help, private QA guidance, and migration support.
• Custom enterprise builds are optional services for organizations with stricter packaging needs.
• A future cloud companion may be explored, but it must remain optional and separate from core local exports.

Privacy Model

• Processing happens locally in the browser after explicit user action.
• No telemetry, analytics, ads, trackers, session replay, remote logging, remote rendering, or export server is used.
• No Jelluvi account is required.
• Conversation content is not uploaded to Jelluvi or any export server.
• Conversation content is not stored by default.
• Browser storage is used for versioned local export, PDF, content, theme, and redaction preferences.
• Optional site access is requested only when the user starts batch discovery or batch export.
• Jelluvi does not request browsing-history (tabs) or browser-downloads permissions.

Limitations

• ChatGPT is the primary v1 platform.
• Secondary platform adapters are best-effort and currently scan visible loaded messages only.
• The extension exports the current conversation only; it does not scrape account-wide history in the background.
• PDF output is generated locally from the normalized conversation model. If local PDF generation fails, Jelluvi falls back to local PDF-ready HTML and shows a warning.
• PDF v1 embeds local Noto Sans and Noto Sans Mono fonts with Latin, Greek, and Cyrillic support. CJK text, complex emoji, and advanced formula layout may use fallback glyphs; formulas are preserved as plain text.
• PNG export is a local semantic long-image renderer for moderate selected or range exports. The maximum local PNG height is 16,000 px; longer chats fall back to a local text explanation and should use selected messages, ranges, PDF, HTML, or text formats.
• ZIP bundle mode stores selected formats under canonical conversation.* names, includes manifest.json with settings and file hashes, and preserves embedded data-image assets under assets/ with hashed filenames.
• Some AI platform UI changes may require fixture and selector updates.

Troubleshooting

• Run pnpm build again after changing source files, then reload the unpacked extension.
• If provider detection does not answer, the popup exits the checking state after three seconds and shows Retry. Reload Jelluvi and the chat tab if retry still fails.
• If no messages are found, confirm the active tab is an open supported AI chat conversation.
• If an export is marked partial, let the current chat finish loading and export again.
• If a download does not appear, check whether the browser blocked page-initiated downloads.
• If a secondary platform export looks incomplete, verify the first and last messages before relying on the file.

Packaging

pnpm build
pnpm package

The package script writes release/jelluvi-v<version>.zip and a matching .sha256 checksum.

Repository Hygiene

Before publishing changes, verify that generated artifacts and local files are not tracked:

git ls-files

Run a current tree secret scan:

gitleaks detect --source . --redact --verbose

For a full git history review, inspect all reachable commits and then run the same scanner against the repository history:

git log --all --oneline
gitleaks detect --source . --redact --verbose
