How do you write a letter with AI in Moleculai?

Set the parameters: topic, format, tone, and length — the platform generates a result in seconds. Nano Banana, ChatGPT, Claude, and 6 more models are available.

Which AI models are good for text generation?

All models work for text generation, each in its own way. Claude produces polished, well-structured text. ChatGPT is more lively and conversational. DeepSeek is strong at logic and argumentation. Grok stands out with unconventional phrasing. Gemini works well with facts. Kimi holds context across long tasks. Llama is predictable and stable. Qwen is best for technical texts. Nano Banana is for creative experiments.

How much does it cost to write a memo with AI, and is there free access?

For writing letters, start with the free generations available after sign-up. If you like the results, choose a plan. Pro: ≈$20/month with a 2,000-token limit. Plus: ≈$36/month, 5,000 tokens. Expert: ≈$94/month, 10,000 tokens. All models are available on every paid plan. An annual subscription works out cheaper.

What's the quality of a letter written by AI?

With a precise prompt, the letter-writing tool delivers a result ready for publication after minimal proofreading. The key is detail: the more input you give (tone, structure, examples), the better the output. Claude holds a formal style, ChatGPT a conversational one, DeepSeek a technical one. Compare models on the same request and pick the best one. The final text is a solid basis for further work.

What tasks does the AI assistant for writing letters handle?

The task of writing letters is solved through a text prompt: describe what you need — get the result. ChatGPT, Claude, DeepSeek, and 6 more models are available. Each interprets the request differently, giving you a choice of style and approach. For professional tasks, one good generation plus some polishing is usually enough.

Why is Moleculai better than other services for text generation?

When looking for a letter-writing tool, the choice usually comes down to one service. With Moleculai you're not limited — many models in one interface let you try each one and pick the best result. Savings: one subscription instead of several. Convenience: Russian interface, hassle-free payment.

Give me three versions on one topic: different in tone and length. Under each, one line on who it suits.
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.
Write in someone else's style
Write a text in the style I name: match the vocabulary, rhythm and sentence length to it, keep my topic.
Outline the text
Build an outline for the text to come: what each part covers, in what order and roughly how long. I will send the topic in my next message.

Examples created by our users

IIvyWrites fan fiction
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.
MMarinaRuns a children's club
I write stories for the sessions: I give the topic and the age of the group and get a finished text. That used to take an evening, now it is a couple of minutes.
PPeterWrites greetings
I ask for three versions on one topic, different in length and tone. I take the closest one and tweak a couple of lines to sound like me.
