One shortcut. Whatever’s on your screen.
A problem set at 1 a.m., a paper full of notation, a spreadsheet that says #REF!, a bill that went up. Same habit every time: box it, ask, and watch the answer drawn on it.
Stuck at 1 a.m.? Ask the page.
Select the step you don't follow, in a problem set, a lecture slide or a paused lecture video, and ask why. tintlo talks you through it while it draws on the working itself.
Ask it things like
- “Why is this sine and not cosine?”
- “Where did the 2x come from?”
- “Is my working right so far?”
- “What did she just write on the board?”
Hints before answers
Learning Mode nudges you to the next step instead of handing over the solution, so it sticks.
Maths, typeset in place
Each step is written out next to the line it explains, not in a chat window somewhere else.
Revision that writes itself
Every explanation lands in your Notebook with its screenshot. Export it as PDF or Markdown before the exam.
Read the paper, not ten tabs about it.
Select one equation, one figure or one paragraph of methods and ask what it means. tintlo labels each part where it sits, so the explanation stays attached to the paper.
Ask it things like
- “What does each symbol mean here?”
- “Explain figure 3.”
- “Why divide by √d before the softmax?”
- “What's the difference between these two curves?”
Notation, term by term
Every symbol in an equation is underlined and labelled in the order it's explained.
Figures, pointed at
Arrows land on the curve, the axis or the outlier that the explanation is about.
Filed under the paper
Explanations are saved to your Notebook under the paper's title, searchable when you write it up.
The formula, the dashboard, the menu you've never opened.
Ask about the thing in front of you instead of searching for it. tintlo points at the exact cell, chart or button, so you never have to translate an answer back onto your screen.
Ask it things like
- “Why does this cell say #REF!?”
- “What's this chart actually telling me?”
- “Which button adds a footer?”
- “Summarise this page in three points.”
Right on the cell
The broken cell is circled and the part of the formula that lost its reference is labelled.
Any app, any menu
Buttons and fields are read directly, so arrows land on the exact control you need.
Safe on calls
tintlo's drawings hide automatically when you share your screen, and come back afterwards.
Read the stack trace without leaving it.
Select an error, a log line or a function you inherited, and ask what's going on. tintlo marks the line that matters and explains it in plain words.
Ask it things like
- “What does this error actually mean?”
- “Which line is the real cause?”
- “What does this regex match?”
- “Why is this returning undefined?”
Any editor, terminal or console
tintlo reads the screen, not your project, so it works wherever the error shows up.
Only what you box
Only the region you select is processed. The rest of your code is never captured.
You keep the keyboard
tintlo explains and draws. It never types into your editor or runs anything.
A second pair of eyes on the working.
Check a student's solution, find exactly where a derivation goes wrong, or get a clearer way to explain a step before class.
Ask it things like
- “Where does this solution go wrong?”
- “Explain this step for a 15-year-old.”
- “What's a simpler way to show this?”
Mistakes, circled
The line where the working goes wrong is circled on the student's own page, with the fix beside it.
Handouts from explanations
Save the explanations you like to your Notebook and export them as PDF.
Classroom controls
On a school plan, Learning Mode can be required and tintlo paused during exams.
Pause the video. Point at the confusing bit.
Online courses move on whether you followed or not. Pause, select the slide or the frame, and ask what you missed.
Ask it things like
- “What did he just draw?”
- “Why does this step work?”
- “Explain this diagram simply.”
- “What should I know before this lesson?”
Paused videos and slides
Works on course pages, slides and most paused lecture videos. Some protected streaming video can't be captured.
Keep asking
Follow-up questions on Pro and Max: click the mic on the frozen box and ask again.
Your own course notes
The Notebook builds a searchable set of notes as you go, one explanation at a time.
The bill, the form, the setting that makes no sense.
Official letters and settings screens are written for someone else. Select the confusing part and ask what it means for you.
Ask it things like
- “Why is this bill higher than last month?”
- “What goes in this box?”
- “Is it safe to turn this setting off?”
Line by line
Charges, form fields and settings are circled and explained in plain words.
Card numbers stay private
Card numbers are blurred on your computer before anything is sent.
Sensitive apps left out
Password managers and banking apps are excluded by default, and you can add your own.
Whatever you're stuck on, ask it there.
