Many researches shows that students which use social media more than three hours per day have lower grades. In our opinion this is because the constant notifications make difficult to concentrate, so the information is not stay in the memory.
We propose to migrate our reporting to the new platform in Q1. This will reduce costs a lot and the team will be more productive, because the old system is very slow and nobody likes it.
We are very sorry for the delay, it was not our fault but the supplier one. We will try to send you the goods until Friday, please be patient with us and don’t cancel the order.

Same task, both tools: writing a LinkedIn post about your career change
You're a Russian engineer turned product manager. You want a LinkedIn post in confident English from a thought you had in Russian. Here's what each tool does.
With Wordtune
- Translate your Russian thought to English using Google Translate (separate tab).
- Get: «In the last year I moved from engineering to product management. It was difficult but interesting. I want to share three lessons.»
- Paste into Wordtune. Try rewrite suggestions.
- Get options: «Over the past year, I transitioned from engineering to product management. The journey was challenging but rewarding...»
- Pick best variant. Copy to LinkedIn (separate tab).
The downside: Three tabs (Translate + Wordtune + LinkedIn). The translation loses the Russian aspect markers («перешёл» perfective vs «переходил» imperfective — Diglot would handle this, Translate treats them generically). Wordtune polishes the English but doesn't catch potential perfective-leak in the surrounding sentences if you continue writing.
With Diglot
- Open Diglot editor. Type your Russian thought directly — the editor accepts mixed-language drafting.
- Highlight Russian paragraph → translate to English. Diglot routes through engines tuned for professional register, preserving aspect distinctions (`перешёл` → confident past-perfective «I transitioned», not the indeterminate progressive Google Translate often produces).
- L1-aware grammar checks the English output for Russian-transfer patterns: article omission, missing copula, perfective-vs-progressive drift.
- Cowriter Edit mode: «tighten to LinkedIn-post register, confident not deferential». Cuts hedging Russian-influenced phrasing.
- Copy final English to LinkedIn. Authorship Certificate logs your keystrokes — if your post somehow gets falsely flagged as AI-generated, you have cryptographic proof of authorship.
The upside: One editor for the whole flow. Translation preserves aspect distinctions Russian speakers care about. Rewrite is aware of your L1, so it avoids re-introducing patterns the grammar checker just removed. The final post sounds confidently you, not laundered through three generic tools.

Where Wordtune ends and Diglot begins
A rewrite-first English-improvement product — strong "sound more natural" messaging in a browser-based editor.
Wordtune is one of the cleanest English-rewriting products on the market. Built by AI21 Labs (founded 2018, Stanford-rooted research lab co-led by Yoav Shoham), its messaging — "sound more natural," "clearer English" — speaks directly to writers who already have an English draft and want to improve it. Diglot solves a different problem: the work of getting from a thought in your native language to a polished English draft in the first place. If you live in the second half of that workflow, Wordtune may be ideal. If you live in both halves, read on.
What Wordtune sells
- Clearer English rewrites
- More natural wording suggestions
- Writing fluency and confidence
- Browser-based editor (not just a sidebar)
- Education and business positioning with clear tier ladder
Why Wordtune wins
- Very clear "rewrite and fluency" messaging — owns "sound more natural"
- Easy-to-understand consumer pricing ladder
- Editor workflow that looks more coherent than a pure utility
- Explicit support for educational use cases
- Strong rewrite quality for English-first writers
Wordtune wins when
- You already have an English draft and want it to sound more natural
- You don't need translation as part of your writing workflow
- You write fluent English natively but want a stronger rewrite assistant
- You prefer a clean editor focused only on rewriting
Switching from Wordtune to Diglot — practical guide
If Wordtune is your daily rewrite tool, the question is whether you live in the rewrite-only slot (Wordtune wins) or the full-production slot (Diglot fits).
1. Check your actual workflow
Open your last 3 documents. How did each one get written? If you typed English directly and Wordtune helped polish, you're a rewrite-only user — Wordtune is the right tool, don't switch. If you drafted in another language and translated to English before polishing, you're a full-production user — Diglot replaces the entire loop.
2. Sign up Diglot free tier, write your next document there
No credit card. Use Diglot for one full document — essay, business email, LinkedIn post, whatever. Pay attention to whether the translation + grammar + rewrite working in the SAME editor changes how the work feels. Most ESL writers report a noticeable drop in cognitive load after one full-document session.
3. Compare rewrite quality directly
Take a sentence you wrote. Run it through both Wordtune and Diglot rewrite. Honest answer: Wordtune's rewrite is purpose-built and produces excellent variants. Diglot's rewrite is good and is informed by your L1 (Russian writer gets rewrites that avoid Russian transfer patterns). For pure rewrite quality on isolated sentences, Wordtune still wins. For rewrites woven into the surrounding L1-aware document context, Diglot wins.
4. Decide based on document length + language pair
Short English-only writing (LinkedIn post, single email): Wordtune is enough, no need to switch. Long mixed-language work (essays, papers, business docs): Diglot replaces Wordtune + Google Translate + Grammarly with one editor. Most users land at Spark ($19/mo) for the bundling — translation + L1 grammar at a comparable price to Wordtune Unlimited alone ($13.99/mo). The Authorship Certificate is free and unlimited on every plan.
5. Keep Wordtune for what it does best (optional)
Wordtune Free (10 rewrites/day) is a useful fallback. Some users keep it for browser-extension rewrite suggestions in environments outside their main writing tool. Once Diglot's browser extension ships, that gap closes.
Honest about friction: Wordtune's rewrite quality on isolated English sentences is purpose-built and excellent — AI21 Labs has years of research depth behind it. Diglot's rewrite is good but not specialty-grade. Where Diglot wins is the workflow envelope around the rewrite. If your use case is dominated by isolated rewrites, Wordtune is still the rational choice.
Deep dive: rewrite-only vs full L1→English production
Wordtune occupies a specific slot in the writing-tool landscape: rewrite-first. Built by AI21 Labs (Stanford-rooted research lab founded 2018, led by Yoav Shoham), its core competence is taking an English sentence and offering multiple natural-sounding variants. Drop a sentence in, get four rephrasings, pick the one that sounds best. This is excellent at what it does, and for writers who already have English drafts that need polish, it's the right tool.
Diglot occupies a different slot: full L1 → English production. The product exists because most ESL writers don't have an English draft to polish — they have native-language thinking that needs to become an English document. The work that precedes the «polish-this-English-sentence» step (translation, register tuning, L1-aware grammar feedback) is where Diglot lives. Wordtune assumes you've already done that work somewhere else; Diglot is the workspace where you do it.
This is why side-by-side comparisons of «which tool writes more natural English» can be misleading. Wordtune wins isolated rewrite tasks. Diglot wins the overall English-document workflow for ESL writers — because Wordtune doesn't help you GET to the sentence you want polished. The typical ESL writer using Wordtune is actually running a three-tab loop: Google Translate (L1 → English draft), Wordtune (polish), Grammarly (final grammar). Each tool is excellent at its slot. The friction is the loop itself.
There's a secondary architectural difference: Wordtune ships a Read feature (summarize/explain long texts), continuing the AI21-Labs research thread into reading + writing. Diglot doesn't currently have a comparable Read feature — that's a roadmap consideration, not a competitive moat. If summarization of long texts is core to your workflow, Wordtune Read covers it directly. Diglot users handle summarization via the Cowriter Ask mode (paste the text, ask «summarize key points»), which works but is more freeform than Wordtune Read's purpose-built interface.
Frequently asked questions
Is Diglot a Wordtune alternative for non-native English writers?
Yes, with one important framing: Wordtune is excellent at making an English sentence sound more natural. Diglot is excellent at the full workflow — from your native-language thinking to polished English output. If you only need the second half, Wordtune is great. If you regularly do both halves, Diglot replaces both Wordtune and your translation app in one editor.
Does Diglot's rewrite quality match Wordtune?
Rewrite quality is one of several axes we optimize for, alongside translation accuracy, L1-aware grammar, and workflow continuity. For pure native-English rewriting in isolation, Wordtune is purpose-built and excellent. For ESL writers, our rewrite is informed by knowing your L1 — so it doesn't just suggest a smoother variant, it suggests one that lands on the side of natural English given the transfer patterns your L1 tends to leak.
Why would I use Diglot instead of Wordtune + Google Translate?
That's the exact workflow Diglot replaces. Wordtune + Google Translate + Grammarly is the three-tab loop most ESL writers use. The cost isn't dollars — it's the friction of copy-pasting, losing context, and never having a single editor that understands the whole workflow. Diglot's value isn't being better at any one tool. It's being one tool that holds the whole flow.
Is Diglot more expensive than Wordtune?
Wordtune Plus is $9.99/mo and Unlimited is $13.99/mo. Diglot Spark is $19/mo ($15.83/mo annual). We are priced higher because we bundle translation and L1-aware grammar alongside rewriting. The Authorship Certificate is free and unlimited on every plan. If rewriting alone is your need, Wordtune is cheaper and built for that.
Does Wordtune handle ESL transfer patterns at all?
Not specifically. Wordtune's rewrite engine is tuned for natural-sounding English regardless of who wrote the original. It will smooth «We measured temperature of sample» into «We measured the temperature of the sample» — but it won't tell you that this is a Russian-L1 article omission pattern that will appear in every sentence you write until you internalize it. The corrections are correct; the LEARNING is missing. That's the Diglot wedge for ESL writers.
What are Wordtune Spices and Diglot's equivalent?
Wordtune Spices are pre-built rewrite modes (Continue, Counterargument, Statistical Fact, Joke, etc.) that give AI direction without a freeform prompt. Diglot's Cowriter has parallel functionality via the Edit mode — instead of pre-named Spices, you describe what you want in plain English («make this more confident», «add a counterpoint», «tighten to 2 sentences»). Wordtune's pre-named buttons are faster for common moves; Cowriter's freeform input is more flexible for nuanced asks.
