ThinkLens
Rethink what you read. Mind included.
An AI tool for critical thinking in Telegram. Paste any text and get a structured breakdown — not a verdict of true or false.
What critical thinking means here
Critical thinking is not about calling something “fake news” or winning arguments. It is about seeing structure: what is claimed, what is supported by evidence, what is interpretation, and what persuasion techniques are at work.
ThinkLens helps you practice that habit on everyday texts — articles, posts, essays — with transparent limits: AI reflection, not expert judgment.
How ThinkLens works
- Send or paste text in the Telegram bot.
- Get a structured analysis: summary, scores, reasonable points, potential issues, rhetorical techniques, and why the text feels convincing.
- Optional Plus tools on the same text: argument map, steelman, hidden assumptions, counterarguments.
Rationality Index (0–100) blends clarity, evidence, and factual tone while flagging manipulation and categorical language — always with caveats.
Plus modules
- Argument Map — thesis, sub-claims, support, and counterarguments.
- Steelman — the strongest fair version of the argument.
- Hidden Assumptions — unstated economic, moral, political, or technical premises.
- Challenge — counterarguments, weak spots, clarifying questions.
Free tier: daily analyses in neutral mode. Plus adds depth tools, history, and tone modes.
Principles
- AI analysis, not expert judgment
- Probabilistic language — no absolute truth claims
- Respectful tone toward reader and author
- Transparency about limitations
