Changelog

What's new.

Every TelPrompt release, in plain English. What we shipped, what we fixed, what's next.

v3.0
Current June 2026

A teleprompter that cannot touch the page.

The architecture rewrite. TelPrompt now runs in its own browser window and holds zero page permissions. Voice tracking moved to on-device only. Same product, dramatically more private.

New
  • Standalone window architecture. TelPrompt opens in a dedicated browser window, separate from any tab. No content scripts. No web-accessible resources. A website you visit cannot see, query, or fingerprint it.
  • On-device speech. Voice tracking now uses Chrome's processLocally: true mode. Your audio is processed on your machine and never sent to any server. Falls back to a clear message + Fixed Pace if on-device isn't available — never silently to the cloud.
  • Inlined fonts. Outfit and DM Sans are bundled as data: URIs. Zero external font requests.
  • Detectability test (8 / 8). A manifest-level proof that the extension is structurally incapable of touching any webpage, included as test-detectability.js.
Improved
  • Permissions reduced to ["storage"] only. Chrome no longer shows the "read and change all data on websites you visit" warning at install.
  • WPM math in Fixed Pace mode is now measured from the actual rendered layout instead of a heuristic — accurate at any font size.
  • Mute fully releases the mic stream so Chrome's indicator goes dark when you press M.
Fixed
  • Fixed Pace no longer fails to move when started — measurement now happens after the reading view is shown.
  • The reading box now opens dead-center and is grab-anywhere draggable.
v2.2
May 2026

Saved scripts library.

Save unlimited scripts locally. Click any saved script to load it back. Delete the ones you're done with. All stored in chrome.storage.local, never synced anywhere.

New
  • Script library with save, load, and delete — kept entirely on your device.
  • Word count and estimated reading time at 150 WPM.
Improved
  • Editor surface upgraded to a borderless tonal block with a coral caret.
v2.1
April 2026

Voice tracking refined.

Sliding-window matcher tuned, three sensitivity presets added, and the reading-line glow re-designed.

New
  • Casual, Balanced, and Precise sensitivity presets.
  • Coral reading-line glow band with smooth-scroll easing.
Improved
  • Word matcher now handles mispronunciations and short pauses without lurching.
v2.0
March 2026

The Zahlo Intelligence redesign.

Complete visual rebuild around the Zahlo Intelligence design system. Outfit for headlines, DM Sans for body, coral as the precision accent, generous radii, no borders.

New
  • Voice Tracking (initial release).
  • Fixed Pace mode with WPM stepper (60–250).
  • Mirror mode, drag-and-resize window, keyboard shortcuts.
v1.0
February 2026

Initial release.

A simple teleprompter overlay you could open on any page. Fixed-pace scroll. Adjustable font, opacity, mirror.

New
  • Initial overlay-based teleprompter.
  • Single saved script, mirror mode, basic keyboard shortcuts.
