For writers
A patient reader for your draft, not a ghostwriter.
Paste a draft and ask for one kind of feedback at a time. Several models critique it, and you see where they raised the same problem and where only one did. Free plan, no card.
Try it now. No signup.
Free runs on free open models and never needs a card.
What to ask for
- Clarity: which sentences are vague or could be read two ways.
- Length: a tighter version that keeps every claim.
- Structure: what the main point is and which paragraphs do not serve it.
- Argument: the strongest objections a skeptical reader would raise.
- Facts: a list of every factual claim in the draft, so you can verify each one yourself.
Why several models help with feedback
One model's feedback reflects that model's tastes. When several models flag the same weakness, it is probably real. When only one raises an objection, the Disagreements section shows it, so you can decide whether it matters for your reader.
Keep the voice yours
Write the draft yourself, ask for feedback, then fix the issues in your own words. Keplar can rewrite a passage if you ask, but the most reliable use is as a reader.
Honest about limits
Keplar can be wrong, even when the models agree. Agreement is a signal, not proof. Keplar does not look things up on the web yet, and the sources shown under an answer are the ones the models cite; Keplar has not checked them.
The Free plan runs on free open models, which can be slower when they are busy, and their hosts may log prompts. Health, legal and money answers are general information, not professional advice.

Questions
Will Keplar write my article for me?
It can draft or rewrite a passage if you ask. The page is about the other use: critique that leaves the writing and the voice with you. Follow any rules your publisher, school or client sets on AI-generated text.
Does it check my facts?
No. It can list the factual claims in your draft so you can check each one against a reliable source. It does not look things up on the web yet, and models can agree and still be wrong.
Is my draft private?
Free-plan requests go to free open models whose hosts may log prompts, so do not paste unpublished work you must keep confidential. See the privacy page and the Free plan privacy note in the docs.
