Checking Tamil as a journalist, sub-editor or blogger
If you write formal Tamil for a newsroom, a magazine or a blog, you check the same things in every draft: the consonant after certain words, the written forms of spoken words, and letters that look alike. Thiruttham does that check in the text box you are already writing in, proposes small edits with a reason for each, and changes nothing until you accept it.
Where you can use it
- Gmail, the WordPress and Blogger editors, and most other web text boxes (not every site has been tested), with the Chrome extension on a computer. It stays out of search and sign-in boxes, and you can turn it off for any site.
- The web editor, in any modern browser including on a phone. Your drafts are kept in your browser; an AI check sends the sentences you check (see below).
- Google Docs is not supported yet. Today, paste the text into the web editor, check it there, and copy it back.
Two ways to check: in Chrome, or in the web editor
| Option | In Chrome, in the box you write in | In the web editor |
|---|---|---|
| Suited to | Mail, and posts written directly in WordPress or Blogger | A long draft written elsewhere, or a check on a phone |
| How | Press the Thiruttham button at the corner of the box; the suggestions open in the side panel | Paste or open your text, press Check; the suggestions list beside it |
| Needs | Chrome, or a browser built on Chrome, on a computer | Any modern browser |
| Copying | None: the text stays where you wrote it | Paste in, then copy the corrected text back |
Rules first, AI second
Every suggestion says which layer made it. The fixed rules are written code that runs in your browser, needs no account and gives the same answer every time. They cover consonant doubling after listed words and endings, standard spellings, and the written forms of a list of 45 spoken words. The AI-assisted check handles what depends on meaning: similar-sounding letters, agreement between subject and verb, and spoken forms beyond the list. It needs a sign-in and shows an edit only when it is confident, so it can miss a mistake, and it can be wrong.
What is sent
- A rule check runs in your browser and sends nothing.
- An AI check sends the sentences you check, only when you press Check after signing in, to our server and to a language model provider whose terms exclude training on your text and keeping it. Each checked sentence is kept encrypted for up to 30 days so that a repeat check is fast; no person reads it. If you choose to report a correction, that one sentence is kept longer, with your consent.
- Your protected words are kept in your account, so the list needs a sign-in. Words on that list, such as names, are never changed.
The Privacy page has the full statement.
What it will not do
- Change your text without your click. You can undo an accepted change straight away.
- Today it does not rewrite, translate or draft text for you. It proposes small corrections to the text you wrote.
- Promise to find every mistake. A text with no suggestions can still contain mistakes, and a suggestion can be wrong; you can dismiss it, protect the word, or report it.
Try it on your own text
Replace the sample below with your own Tamil and press Check. The box runs the fixed rules only; agreement between subject and verb and similar-sounding letters need the AI-assisted check, which needs a sign-in.

You can start a 7-day trial of Pro yourself, once, with no payment needed. Pro is ₹299 a month or ₹2,799 a year.
Can I check Tamil inside WordPress or Blogger?
Yes, with the Chrome extension on a computer. A small Thiruttham button appears at the corner of the editor's text box; press it, and the suggestions open in Chrome's side panel.
Will it change names in my article?
Names on your protected list are never changed. The list needs a sign-in; without one, a rule check can still suggest a change to a name, and you can dismiss it. Nothing changes until you accept it.
Does my article leave my computer?
A rule check runs in your browser and sends nothing. An AI check sends the sentences you check, only when you press Check after signing in. They go to our server and to a language model provider whose terms exclude training on your text and keeping it; each is kept encrypted for up to 30 days so that a repeat check is fast, and no person reads it.
Does it work in Google Docs?
Not yet. Paste the text into the web editor, check it there, and copy it back.
Does it work on a phone?
The web editor does. The Chrome extension cannot be installed on a phone.
