How do I add punctuation to text online with Moleculai?

Write your task in the chat — from a short request to a detailed description with style and length requirements. The more detailed the prompt, the more accurate the result. DeepSeek and Kimi are especially good for text editing. The platform has many models total, switching between them takes one click. Generation takes seconds, and the text is ready to use right away or refine further.

Which AI models are good for text editing?

For punctuation, start with ChatGPT — versatile and fast. If you need a clear structure, switch to Claude. For analytical requests, DeepSeek is more precise. Gemini is strong with information and translation. Kimi handles long texts in one pass. Grok gives a fresh style without bureaucratic phrasing. Llama is stable at scale. Qwen excels at multilingual tasks. All models are included in the subscription.

How much does adding commas to text online cost, and is there a free option?

You can try adding punctuation to text online for free — test generations are available after sign-up. For ongoing use, there are plans: Pro at ≈$20/month (2,000 tokens), Plus at ≈$36/month (5,000 tokens), and Expert at ≈$94/month (10,000 tokens). All models are included in every plan.

What quality does online punctuation checking deliver?

The quality of the result for text editing depends directly on the prompt. Specify the topic, style, length, audience, and format — the AI produces coherent text ready to use. For professional tasks, we recommend Claude or ChatGPT. A final proofread is still needed — AI doesn't replace an editor, but it takes on 80-90% of the work. Try several models — quality varies.

What tasks does online punctuation placement handle?

The punctuation task is solved through a text prompt: describe what you need, and you get a 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 with a bit of refinement is usually enough.

How is Moleculai better than other services for text editing?

Instead of $20-40/month for one model, it's from ≈$20 for all nine. Plus you can compare results from several AIs in seconds, without switching between tabs.

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.
BBrianNewsletter author
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.
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.
