Your reading load changed. Your reading interface didn't.

AI can generate a report in seconds. Documentation keeps growing. Research, newsletters and long-form content keep piling up. TempoLens gives you another way to move through that text.

📚

Too Much to Read

Long AI answers, documentation, research and articles compete for the same limited hours in your day. TempoLens lets you choose a faster reading pace when the material allows it.

🧱

Dense Content

Headings, lists, tables and code make ordinary speed readers difficult to use. TempoLens recognises structure so important context doesn't disappear into a wall of flashing words.

😴

Attention Drifts

Long pages make it easy to skim, jump around or reread the same paragraph. Flash Mode gives you one focal point and a consistent reading rhythm.

Two reading modes. Choose what fits the text.

⚡

Flash Mode (RSVP)

F o cused

Words appear one at a time in a fixed position, so your eyes stay focused on one reading point. Adjust the pace at any time.

Best for:

  • Articles
  • AI responses
  • Documentation
  • First-pass reading
👁️

Focus Mode (Bionic)

Reading is one of the most powerful tools we have for learning and growth.

See the full text while the beginning of each word is visually emphasised. Read, scan and review at your own pace.

Best for:

  • Reviewing material
  • Scanning for information
  • Slower, careful reading
🧠

Flexible Reading Controls

Reading preferences differ from person to person. TempoLens gives you control over pace, presentation, font size, contrast and reading mode so you can find a setup that feels comfortable.

Accessibility features:

  • Adjustable reading speed
  • Adjustable font size
  • OpenDyslexic option
  • High-contrast and OLED themes
  • Flash Mode (one word at a time)
  • Focus Mode (visual word anchors)

Some users with attention or reading difficulties prefer externally paced or highly configurable reading interfaces. TempoLens is a productivity and accessibility tool, not a medical treatment.

Speed reading without destroying the structure.

TempoLens recognises the structure of what you're reading instead of treating every word the same.

📝 Paragraphs
Word-by-word RSVP
📋 Lists
Displayed as full blocks
💻 Code blocks
Syntax highlighted, paused
📊 Tables
Shown complete with structure
🏷️ Headings
Context markers, brief pause

Example: reading documentation

H
Configuration Options (pause)
P
word... by... word...
</>
const config = {
  speed: 350,
  mode: 'rsvp'
}
(pause for reading)
P
Paragraph continues...

Code stays code. Lists stay lists. You're not mentally reconstructing structure while speed reading.

🤖

Built for AI-generated text.

ChatGPT, Claude and Gemini regularly produce long, structured answers with headings, lists and code. TempoLens preserves that structure while you read, making AI output one of its most useful workflows.

A simple fallback - paste directly into the floating reader.

Read the passage normally, then try the same idea with RSVP at a faster pace. Adjust the speed until you find a level that feels useful.

Traditional Reading

Reading is one of the most powerful tools we have for learning and personal growth. Yet most of us read the same way we did in elementary school - word by word, line by line, eyes jumping across the page. This works, but it's inefficient. Your eyes spend more time moving than your brain spends processing. What if the words came to you instead? That's the core idea behind RSVP: Rapid Serial Visual Presentation. One word at a time, right where you're looking.

Frequently asked questions

Flash Mode presents every selected word rather than automatically skipping words. However, reading faster can reduce comprehension, particularly with complex material. TempoLens lets you control the pace, pause and move backwards whenever needed. Choose the speed that fits what you're reading.

It can. Reading speed and comprehension involve a trade-off, especially with dense or unfamiliar material. TempoLens does not promise identical comprehension at every speed. Use faster settings for material you want to move through quickly and slow down when details matter.

TempoLens combines fixed-position RSVP reading with a full-text Focus Mode, while preserving useful structure such as headings, lists and code. It works directly from selected text across the web and processes selected reading text locally in your browser.

Yes, with Clipboard Mode. Copy the text you want to read and open TempoLens. Native one-click PDF reading is not currently available.

Yes. Long AI responses are one of TempoLens' core use cases. TempoLens recognises headings, bullet points and code blocks so structured AI output remains easier to follow while reading.

You can start immediately. Begin at a comfortable pace and adjust the speed depending on the material. There is no target speed you need to reach - the useful speed is the one that balances pace and understanding for you.

Some people with attention difficulties prefer a reading interface with a single focal point and external pacing. TempoLens lets you adjust speed, font size, themes and reading mode to find a setup that works for you. TempoLens is a productivity/accessibility tool and is not a treatment for ADHD.

TempoLens includes an OpenDyslexic font option, adjustable font sizing, high-contrast themes and one-word-at-a-time Flash Mode. Reading preferences vary widely, so the interface is designed to be configurable rather than assuming one format works for everyone.

The text you choose to read is processed locally in your browser. TempoLens does not collect your browsing history or send selected page content to our servers for reading. See the Privacy Policy for details about license and account-related data.

Yes. The Free plan includes up to 15 reads per day with no credit card required. Upgrade to Pro only if you need unlimited usage and additional Pro features.

Start with the free plan or try Pro for 7 days without a credit card. Paid purchases are covered by our 30-day money-back guarantee.
