Changelog
ZapVox historical archive, from v1.0.0 to v3.9.47.
π This page is the
historical archive (v1.0.0 β v3.9.47). Later versions live in
What's new, updated at every release.
βSend nowβ button, βClear sentβ, and a more readable scheduling screen
- π Send now β each scheduled message now has a button to fire it right away, without waiting for its time. Great for testing. It still respects every safety limit.
- π§Ή Clear sent β removes all already-sent, failed or expired schedules at once, keeping the list clean.
- More readable safety screen β the fields (allowed hours, minimum interval, limits) were reorganized with the label on top and the field below, fixing the misalignment.
Message scheduling actually sends again
- Sending fixed β in some cases the scheduled message was typed into the chat but not sent, staying as a draft. We rewrote sending using WhatsApp's native mechanism: now the text (including multi-line messages) is filled in and sent reliably.
- No page reload β sending happens without refreshing WhatsApp Web, quietly in the background.
Safer scheduling: it checks the recipient before sending
- Double recipient check β before sending, ZapVox confirms through two independent sources that the open chat really is the right contact. When in doubt, it doesn't send β avoiding messages to the wrong person.
- Navigation without reloading β opening the right conversation no longer requires a page refresh.
- More punctual timing β we tuned the send randomization so it never fires early.
Schedules synced across computers
- Switch PCs without losing anything β your schedules are now saved to your account and show up on any computer you sign in on.
- Manage from the dashboard β view, edit the text, reschedule, pause or delete your schedules right from the ZapVox dashboard on the website.
- Click Pro features β tapping a Pro-only feature opens the pricing page in your language.
Scheduling fixes: the list is back, variables moved into the WhatsApp mini-popup, and the hidden menu
- The schedule list is back β we fixed a case where the list (and the form) disappeared for non-Pro users because the plan notice was wiping out the section. Everyone can see their schedules again.
- Variables moved into the WhatsApp mini-popup β the variables (
{{name}}, {{date}}β¦) moved out of the extension popup and into the scheduling mini-popup inside WhatsApp itself. The popup is cleaner and you insert variables right where you write the message.
- No more menu hidden in the corner β fixed a visual glitch where the inline menu got stuck in the screen corner when WhatsApp was disconnected.
One active browser per account
- One active session at a time β your ZapVox account is now active in one browser at a time. If you sign in on another browser or computer, the most recent session takes over and the previous one shows a friendly notice.
- "Use here" button β from the notice, one click brings the session back to the current browser, no need to sign out and back in.
- Server-side check (newest wins) β protection against shared-account use. You're still free to switch between your own devices anytime. Need several browsers at once? Talk to us at [email protected].
Message scheduling becomes a Pro feature (Free gets 3 per day)
- Scheduling messages is now part of Pro β on Free you can schedule up to 3 messages per day to try it out; on Pro it goes up to 100/day (fair-use that protects your number).
- Server-side plan and quota check β verification now happens reliably on the server, counting the day's schedules.
- Gentle notices β when you get close to or hit the Free limit, a light notice appears with the option to check out Pro, without blocking your flow.
- On-screen reminders (π) stay free on every plan.
Scheduling gets a visual refresh
- New look β we polished the Scheduling and Reminders sections: spacing, icons, status badges, and the form are clearer and nicer to use.
- No behavior changes β just prettier and easier to read. All safety controls and limits stay exactly the same.
Reminders (π) and Scheduling (π
) are now separate sections at the front of the popup
- Two distinct sections β Message scheduling (π
, sends to a contact at a set time) and Reminders (π, on-screen alerts just for you) now each have their own accordion, right at the top of the popup.
- Nothing buried anymore β scheduling is no longer hidden inside "π¬ Chat tools". Open the popup and both are right there in front.
- Each with its own icon β π
to schedule messages, π for personal reminders. No more mixing up "send to someone" and "remind me".
- Everything still works the same β the status list, "π Sending safety", the variables (
{{name}}, {{date}}β¦) and the anti-block limits are exactly as before, just easier to find.
Safety controls always visible + weekly cap + live usage
- Sending safety always visible β the protection controls (allowed hours, minimum interval, limits, missed-message policy) now show right below the schedule list, without needing to open the form. Nothing stays hidden.
- New weekly limit β on top of the hourly (20) and daily (100) limits, there's now a weekly limit with a default of 300 sends and a fixed safety cap of 500. If the week is exceeded, sending is deferred (never lost).
- Live usage counters β next to the limits, you see how much you've used: "Hour: X/20 Β· Day: Y/100 Β· Week: Z/300". It's highlighted once you pass 80% of the cap.
- Clear status on every wait β when a send is deferred by hitting a limit, the item shows "β Waiting (hourly/daily/weekly limit)" instead of looking like a silent failure. Real errors still show the reason.
- 8s floor reinforced β the caption makes it clear: randomness can only increase the spacing between sends, never drop it below 8 seconds.
Full schedule list + stronger anti-block protection
- Full schedule list β the scheduling section now shows all items (messages and reminders) with recipient, message snippet, time, and a status badge: β³ Scheduled, β
Sent (with the time), β Error (with a readable reason β "number has no WhatsApp", "limit reached", etc.), βΈοΈ Paused, π« Skipped, and β Waiting for allowed hours.
- Per-item actions β βοΈ Edit (reopens the form to change text, time, or recipient), βΈοΈ/βΆοΈ Pause/Resume, β
Mark done (marks it complete and removes it from the queue), and ποΈ Delete.
- More quick variables β on top of Name and Full name, now also Date, Time, Date & time, and Weekday, inserted with one click.
- Anti-block floor β the minimum interval between sends now has an 8-second floor (cannot be disabled): even in a burst, sends stay 8β20 seconds apart to protect your number.
- "If WhatsApp was off" β a new option for missed messages: send as soon as possible, only if it's the same day, or send all even if late (with a 48h safety cap).
Scheduling fixes and improvements
- No more repeated resends β fixed a case where a scheduled message could be resent in a row when the send result was uncertain (e.g. the tab reloading mid-send). Now, when in doubt, ZapVox never resends: each one-time schedule sends at most once.
- Sending-safety controls β a new section to set allowed hours (any time, business 8amβ6pm, or custom), a minimum interval between sends, and per-hour/per-day limits. Outside the window, sending is deferred to the next window β never dropped. The anti-ban ceilings (20/hour and 100/day) stay fixed.
- Message variables β quick buttons to insert Name, Full name, Date, Time and Weekday, auto-filled with the recipient at send time.
- Front-page shortcut and clearer error messages (number not on WhatsApp, limit reached, contact with no recoverable phone number).
New
- Message scheduling v3 β sending messages at the scheduled time is back, now with the recipient locked in when you create the schedule and a new engine based on WhatsApp's official link: it opens the correct chat and pre-fills the text, far more reliable than the previous approach. Still opt-in (off by default), with jitter and safety limits (20/h, 100/day) to protect your number. Available for individual chats only β groups are not supported.
Fixes
- Side panel on Microsoft Edge β the button that opens the side panel didn't work reliably on Edge (the browser has its own sidebar and the API behaves unpredictably there). On Edge, ZapVox now opens in a floating window β same content, predictable behavior. Nothing changes on Chrome.
Improvements
- Glossary v2 (Pro) β besides guiding the AI during transcription, the glossary now applies a deterministic post-correction step that guarantees the exact spelling of your terms (names, products, jargon) in the final text.
Transparency & limits
- Fair-use limits in audio minutes β besides the number of operations, plans now also track audio minutes per day, with limits documented per plan.
- Daily window in BrasΓlia time β the limits "day" now resets at midnight BrasΓlia time, no longer UTC.
- Terms of use v1.3 β explicit per-plan limits and clearer, consumer-friendly language.
Plan changes
- Chat tools are now Pro/Trial β π transcript search, π export transcripts (.txt) and π whole-chat summary are now part of the Pro plan (and the 7-day Trial). On the Free plan, the buttons show a π lock with an invitation to check out Pro.
- Trial users keep using everything as before β nothing changes until the 7 days are up.
A tidier popup
- New π¬ Chat tools section β transcript search, daily digest and reminders became subsections inside a single accordion. The popup goes from 7 to 4 top-level sections: cleaner and easier to find things.
- Auto-send toggles together β the auto-send options for individual chats and for groups now sit side by side, in the same section.
- The link to configure keyboard shortcuts (
chrome://extensions/shortcuts) is now always clickable on the popup home screen.
Improvements
- Productivity-focused daily digest β the daily summary got a dedicated prompt: organized per conversation (π), highlighting action items and scheduled commitments. Less prose, more what-to-do.
- Click to copy β any item in the daily digest or search results goes to your clipboard with one click.
- Contact/chat name highlighted in search and digest results.
New
- ποΈ Automatic daily digest (Pro/Trial) β at the time you choose, the AI gathers all the voice messages you received during the day and delivers a single summary, as a notification and in the ZapVox panel. No need to open chat after chat.
New
- π Search your transcribed voice messages β find any word ever said in your audios right from the side panel. Case and accent-insensitive, and it all runs in your browser β nothing leaves it. Ctrl+F for your voice.
New
- π Custom glossary (Pro) β teach the AI the terms of your daily routine (medication names, legal jargon, proper nouns) and transcriptions spell them exactly right. Saved to your account.
- E-mail sign-in β a third way to sign in: receive a code by e-mail, no Google or Microsoft account needed. The flow picks up where it left off even if the popup closes.
- Long audios transcribed end-to-end β multi-minute voice messages are no longer cut short: the transcription covers the whole message, start to finish.
- β±οΈ Time-saved counter in the panel β see how many minutes of audio you didn't have to listen to.
Fixes
- Phase 7 β extended retry for group audios β in busy groups, WhatsApp takes longer to hydrate audio metadata. Added an extra retry phase with 8s of additional wait after all other strategies fail, before showing a loading error.
- Friendlier audio error message β suggests clicking again manually before asking for an F5.
- Improved diagnostics in logs (includes
isGroup and msgType flags).
Tests
- 397/397 tests green (4 new ones covering v3.4.14 error patterns).
Summaries in impersonal voice
- Summaries and topics no longer attribute actions to proper names β before: "Rafael needs to do X". Now: "X needs to be done". Avoids confusion (the reader can't tell if they are the sender/recipient/observer in a group) and eliminates attribution errors.
- Proper names are preserved when they truly matter ("Call Dr. Silva at 3pm", "PIX payment to XYZ Store").
- Edge Functions
summarize v14 and topics v17 deployed.
Milestone
- ZapVox approved by Google and officially published on the Chrome Web Store. Available to everyone β install it free at chromewebstore.google.com.
Fixes
- Copy bug fix: duplicated watermark β copying a transcription manually duplicated the "ποΈ zapvoxia.com.br" watermark. Now built from a single deterministic source.
- CSS contrast fix β in dark mode, transcriptions could become unreadable due to a hardcoded
color: #111. Fixed with WCAG AAA contrast in both themes.
- Manifest source consistency β Supabase host_permissions aligned between source and dist.
New
- Universal glass morphism on the transcription card β works with any WhatsApp theme and any custom wallpaper (photo, gradient, solid color). Near-opaque background with
backdrop-filter: blur(14px) saturate(1.4) guarantees readability in 100% of scenarios.
- WCAG AA 7:1 contrast enforced.
- Automatic adaptation via
prefers-color-scheme + body[data-theme].
New
- Sentiment cache β analysis survives an F5 (7-day TTL, no API cost on re-render).
- BETA badge in the popup.
- Adaptive theming via WhatsApp's native CSS variables.
UI cleanup
- Inline π Sentiment button β tone analysis right on the audio card. Result shown in a separate chip, never contaminating copy/auto-send.
- "Topics" button removed (orphaned since v2.2.1 merged topics into summaries).
Critical fix
- Bug: Portuguese audio transcribed in English. In "Automatic (SmartLang)" mode the Service Worker fell back to
navigator.language, which returned en-US on Chromes with an English UI β forcing Whisper to transcribe Portuguese audio into odd English. Fixed to let Whisper auto-detect from the audio itself.
Fixes
- GET_USER_PLAN handler fixed β Pro users were blocked with "Scheduling is Pro-only" even while paying, because the handler was missing.
- Friendlier deleted-messages UX β instead of automatically replacing deleted content, shows an opt-in "π View original (ZapVox)" button. More respectful and aligned with the CWS Single Purpose Policy.
Robust cascade
- Deterministic 5-phase cascade for audio loading (Phases 1a/1b/2/3/5) β replaced trial-and-error polling with WhatsApp's own internal primitives.
- Phase 5 β manual decrypt in the Service Worker β last resort when every other phase fails. The SW fetches from WhatsApp's CDN, derives keys via HKDF-SHA256, verifies HMAC and decrypts AES-256-CBC.
- Opt-in telemetry (client) β events sanitized through an explicit whitelist.
Structural changes
- Deleted message recovery (text + images + videos + audios) via local IndexedDB cache with a 7-day TTL. Opt-in in the popup.
- Sentiment analysis as a post-transcription action (BYOK + Cloud).
- Topics merged into Summary β summaries now automatically include the key points.
- Local Whisper removed β the product is now 100% cloud-first (BYOK Groq β BYOK OpenAI β Cloud Edge cascade).
- Free now includes 10 cloud transcriptions/day + BYOK without ZapVox limits (your own key quota applies).
Fixes
- Local transcription is now free for all users (discontinued in v2.2.0 β today it is 100% cloud)
- The 3/day limit now applies only to cloud operations (summary, topics)
- Limit check moved to after local transcription in the transcription cascade
Security
- Removed an administrative debug handler β it allowed improper escalation to Pro
- Removed a debug handler β same vulnerability

New
- Topic summaries β besides free-form summaries, now with key-point extraction
topics Edge Function for server-side processing
- Summary/topics selector in the popup
Improvements
- BYOK Groq β your Groq key as Strategy 2 in the cascade
- AES-GCM 256-bit encryption for BYOK keys (PBKDF2 600k iterations)
- 7 exclusion layers + 5 positive strategies for audio detection
- Hardware compatibility page
