How does AI grammar checking work in Moleculai?

Describe the task in your own words - the AI turns your request into finished content. All 9 models work for text editing: DeepSeek, Gemini, Kimi, Grok, and others. Try DeepSeek and Kimi - you'll see the difference in style and approach. The result appears in seconds. Edit right in the interface or download it as a file.

Which AI models are good for text editing?

Each of the 9 models works for text editing, but with a different focus. DeepSeek: precise phrasing and analysis. Claude: a professional tone and structure. ChatGPT: creativity and versatility. Kimi: handling large texts. Gemini: research tasks. Grok: an unconventional approach. Switching takes a second. Try 2-3 models on the same request to pick the best one.

How much does AI spell-checking cost, and is there free access?

Free access to the text editing tool is available right after registration - try it out at no cost. Paid plans range from ≈$20/month for Pro (9 models, 2,000 tokens) to ≈$83/month for VIP (10,000 tokens, 394 million words, 10,000 images). For comparison: a single ChatGPT subscription costs about $20, while here you get 9 models for less.

What quality can I expect from AI error correction?

The result depends on two factors: how detailed your prompt is and which model you choose. A well-written prompt specifying the topic, tone, and length produces text you can use with minimal editing. Claude and DeepSeek excel at analytical material, ChatGPT at creative work. For important tasks, we recommend trying 2-3 models and picking the best result.

Does AI error checking work for Russian text?

Yes, all 9 models in Moleculai support Russian. This sets the service apart from foreign alternatives, where you often have to switch to English for the best results.

What tasks does AI grammar checking handle?

The tool helps with grammar checking - enter a description and the AI creates the content. It works with any format, from short texts to long-form material. The platform has 9 models for different styles and tasks. Switching between them is instant. The result can be copied or downloaded in one click.

What makes Moleculai better than other text editing services?

The advantage of Moleculai for text editing: you don't have to pick one AI and hope it's the best. Try the same task on ChatGPT, Claude, and DeepSeek at once, then choose the best result.

Ready-made prompts

Rewrite in your own words
Rewrite the text in your own words: keep the meaning, the facts and the figures, drop the clichés and the officialese, make it lively and easy to read aloud.
Check for mistakes
Check the text for spelling, punctuation and style. Give the corrections as a list: before - after - why. Flag the debatable cases separately.
Cut it in half
Cut the text in half: keep only what the meaning falls apart without. Preserve the figures, the names and the conclusions, do not change the style.
Change the tone
Rewrite the text in a different tone - I will say which. The meaning and the structure stay the same, only the vocabulary and the sentence length change.
Continue the story
Continue the text from where it breaks off: keep the style, the author's voice and the characters, and add one plot twist.

I check my students' texts: the corrections come back as a list, "before - after - why". Going through that with a class is far easier.

I cut my emails in half. I asked it to keep only what the meaning falls apart without - open rates went up and unsubscribes went down.

When I get stuck I ask it to continue the scene in my style. The characters' voices are kept, and sometimes the plot twist turns out better than mine.
