Versions follow Chrome's required numeric format (no semver suffixes).
v0.3.0 — May 2026 — Export entire claude.ai projects
New: Project Export. On a claude.ai/project/<uuid> page, paid
users now export the whole project — Instructions, knowledge files,
every conversation in the project, every attachment — as one ZIP.
Triggered from the popup or from a floating button on the project
page; free users get an upsell variant.
ZIP layout: README.md, metadata.json, instructions.md,
files/ (text knowledge + binary uploads merged, with their own
_INDEX.md), conversations/<date>_<title>/ matching the
batch-export per-chat layout, a root _INDEX.md listing every
conversation with status (OK / Skipped: empty / Failed: <err>
/ Not run), and _INCOMPLETE.md only when the /docs or
/files listing call failed. Full spec at
the project-export how-to.
Memory is not included — claude.ai does not expose project
memory in any reachable REST endpoint, and the bundled README.md
documents the omission so it's clear it's not an export bug.
Formats: Markdown / HTML / JSON / TXT. PDF excluded (same
browser-print constraint as batch).
Reciprocal mutex with batch export: only one in-page paid export
runs at a time. Applying a license while on a /project/ page
flips the upsell button to working state without a reload.
Pre-existing batch-export data-loss path fixed as a drive-by:
same-date+title conversations no longer overwrite each other inside
the ZIP — disambiguated by a shared key set across both modes.
v0.3.1 followup: project-export UI strings localized across all 10
shipping locales; Chrome Web Store long descriptions updated to
mention project export.
v0.2.141 — May 2026 — Claude-style theme is the default
HTML and PDF exports now default to a warmer cream-and-serif theme
that mirrors reading a chat on claude.ai. The cleaner archival look
is still available as Document theme in popup → Advanced →
Export theme.
Existing users who explicitly chose Document on a dev build keep
their preference; everyone else picks up the new default on the
first export after updating.
v0.2.139 — May 2026 — Claude-style PDF goes full-bleed
The cream now reaches the paper edges instead of leaving a 14 mm
white frame around the content. PDF print path moved from
@page margin to body padding so the page itself is full-bleed
while the content keeps its breathing room.
Document theme PDFs unchanged — the historical 14 mm @page margin
is preserved so headers/footers Chrome draws there have somewhere
to live.
For the cream to actually print: tick Background graphics in
Chrome's print dialog. The in-page tip banner calls this out
prominently and Chrome remembers the toggle next time.
v0.2.135 — May 2026 — Claude-style export theme (opt-in)
New optional theme that uses Iowan Old Style / Charter for Latin
body text, Songti SC / Hiragino Mincho for CJK, and a warm
#f9f5ee page background. Reads like a printed page from the
Claude web app.
popup → Advanced → Export theme — pick Claude-style or
Document; the default is Document until the v0.2.141
switch above.
Phase 2 typography lift in the same release: Hiragino Sans GB
and Heiti SC added to the default font fallback stack alongside
the existing PingFang SC / Microsoft YaHei, so Japanese and older
macOS Chinese render in the right visual register.
v0.2.133 — April 2026 — Markdown rendering polish
GFM tables (| col | col | style) now render as proper <table>
elements with header / body, alignment, and inline-md inside cells.
Used to leak as raw pipe-and-dash text in HTML/PDF exports.
v0.2.134 follow-up: ATX headings (# through ######), horizontal
rules (---, ***, ___), blockquotes (> …), and inline
links ([label](url)) all render in HTML/PDF exports. Markdown
exports were already fine — this closes the gap between the two.
v0.2.121 — April 2026 — Visualize-widget export
Claude's inline visualize widgets — SVG diagrams and HTML mockups
Claude generates via show_widget — now ship inside HTML/PDF/MD
exports instead of being silently dropped, and land as sibling
.svg / .html files in the per-conversation folder of bulk-export
ZIPs.
v0.2.127 follow-up: colored diagram nodes (c-blue, c-amber,
c-green, etc.) now keep their colors in the exported SVG. They
used to collapse to all-black flowcharts because Claude's runtime
CSS didn't travel with the export.
v0.2.128 — April 2026 — Welcome page on first install
Fresh installs open the aichatarchive.app/welcome
walkthrough in a new tab so users find the floating Export button
without hunting through Chrome's puzzle-piece menu.
v0.2.129: welcome URL is locale-aware — Japanese-Chrome users land
on /ja/welcome, Korean on /ko/welcome, etc. — across the 9
shipping locales at the time. v0.2.132 added /fr/welcome to
bring the total to 10.
v0.2.130: skipped on enterprise-policy and sideloaded installs so
IT-managed deployments don't surprise employees with an external
tab.
v0.2.126 — April 2026 — Pick which messages to export
New Choose messages… entry on the floating Export menu opens a
side panel with a checkbox per turn. Pick exactly which messages
go into the export — useful when only the last reply is worth
keeping.
Two presets: All (default) and Last turn (last user
question + last Claude answer).
Works for every export format including PDF; the print page picks
up the selection via URL params.
v0.2.125 — April 2026 — Floating button → format menu
The on-page Export button used to export in a single fixed default
format. It now opens a small menu so you can pick Markdown / HTML /
PDF / JSON / Plain text per export, without having to open the
toolbar popup to change format. Keyboard navigation supported.
v0.2.124 — April 2026 — Localized CWS listing
Chrome Web Store listing title and short description now ship in 9
locales: en, zh-CN, zh-TW, ja, ko, es, it, de, pt-BR. Catches
native-language Web Store search instead of only the English-locale
install funnel.
v0.2.132 added French (fr) — 10 locales total.
v0.2.123 — April 2026 — Free unlimited PDF
Daily 3-PDF cap removed. PDF generation runs entirely on your
machine via the browser's print pipeline — there's no server cost
to cap.
The paid tier's three remaining benefits stand: bulk export of
every conversation as a ZIP, attachment bundling (real file bytes
alongside the transcript), and no branding footer on exported
files.
v0.2.119 — April 2026
PDF quota-exceeded message wraps cleanly into two lines (fixes a layout shift).
Dev tooling + store-review assets moved out of the shipped bundle.
v0.2.118 — April 2026
Quieted the PDF-format hints; removed the DEV- license backdoor used only in
development.
v0.2.117 — April 2026
Surfaced PDF format limitations inline (attachments can't bundle into a printed PDF,
the thinking toggle does nothing in PDF) instead of letting users hit them.
v0.2.116 — April 2026
"Include attachments" auto-enables on first license activation. Past users who
activate a license now get the ZIP-with-attachments experience by default,
without hunting through advanced settings.
v0.2.115 — April 2026 — Polar license validation
New: full online license validation against Polar.
Licenses are re-checked at install time and every 24 hours.
7-day offline grace window: if validation can't reach Polar (offline, rate limit),
the license keeps working.
Revoked licenses return the extension to free-tier behavior on next check.
v0.2.114 — March 2026
Fixed: popup version string now pulled from manifest.json, no more drift between
the shipped version and what the popup displays.
v0.2.113 — March 2026
Fixed: "Include tool calls & artifacts" toggle now actually hides tool-call
blocks from the exported transcript when disabled.
v0.2.112 — March 2026
PDF daily quota surfaces on the Export button when depleted, with inline Upgrade
link.
Consolidated paid UI into a single card. Floating Export button on claude.ai can
now be hidden via settings.
v0.2.110 — March 2026
New: PDF daily quota (3/day) for free tier.
Batch export and over-quota PDF routes go to the checkout link.
v0.2.108 — March 2026
PDF typography overhaul — headings, spacing, and code blocks now match Claude's
own UI conventions.
v0.2.105 — February 2026
Fixed: PDF logo renders reliably across viewers.
Icon bundles transparent corners for clean display on colored backgrounds.
Added print-header tip for users on Chromium variants that strip @page.
v0.2.102 — February 2026 — Designed branding
New custom icon.
Zoho-style branding footer on free-tier exports.
Tighter print spacing.
v0.2.100 — February 2026
Fixed: PDF export now opens reliably and produces readable output across
Chromium variants.
v0.2.95 — January 2026 — HTML + PDF launch
New: HTML export (free tier).
New: PDF export via the browser print pipeline (free tier).
Batch export gated behind paid tier.
v0.2.90 — December 2025
Branding footer on free-tier exports; paid license removes it.
v0.2.85 — November 2025
Fixed: present_files bundle correctly when they only appear in tool-use blocks.
Format stability pledge
Once a format is shipped, its structure is frozen in place unless the version
signals a major change. Specifically:
Markdown headers (# title, ## Human (…):, ## Claude (…):) will not rename.
Attachment prefixes (> 📎 Attachment:, > 📎 File:) will not change.
ZIP layout ({date}_{safe-title}/attachments/) is frozen.
Third-party importers can rely on these invariants. See the
format specs for details.
Older versions
Pre-0.2.85 releases were internal or private-alpha and are not documented here.
