Obsidian plugin for sharper thinking
ThoughtLint reviews the active Markdown note in Obsidian and surfaces vague claims, missing assumptions, unsupported statements, weak evidence, and incomplete action plans before you move from notes to execution.
Direct answers
ThoughtLint is a local-first Obsidian plugin that lints reasoning inside Markdown notes. It helps users catch weak arguments, fuzzy claims, and missing execution detail before those flaws turn into bad product, strategy, or meeting outcomes.
ThoughtLint is for people who turn notes into decisions and work: founders, operators, product teams, researchers, strategists, and anyone using Obsidian as a thinking environment instead of a passive notebook.
Most bad work starts as under-examined thinking. ThoughtLint forces clarity by scoring the note, naming the gaps, and giving a cleaner draft you can act on or challenge.
Deterministic review
These checks run on-device with no API key and no server required.
Flags soft language like “some,” “probably,” or “better” when the note needs specifics.
Highlights notes that explore the issue but never state the takeaway, recommendation, or decision.
Finds notes that identify problems without turning them into clear next steps.
Catches plans that mention work without assigning a responsible owner or a concrete due date.
Spots strong assertions that are not backed by evidence, examples, links, or reasoning.
Identifies notes that stay in exploration mode and never resolve into a choice or explicit open issue list.
Surfaces phrases like “I think” or “it seems” when the note should distinguish evidence from assumptions.
For spec-like notes, ThoughtLint checks whether the note defines what done actually means.
For plans and strategies, ThoughtLint checks whether the note states what must be true and what could fail.
Useful output
“
ThoughtLint turns a note from “interesting but fuzzy” into “clear enough to challenge or execute.”
How it works
ThoughtLint reads the active Markdown note in Obsidian and detects the likely note type: research, spec, decision, meeting notes, or strategy.
Local deterministic checks score the note and identify where the thinking is weak, incomplete, unsupported, or ambiguous.
ThoughtLint suggests fixes, rewrites the selected section, and optionally enriches the result with a user-provided model after a clear privacy warning.
Privacy-first by default
FAQ
ThoughtLint is a local-first Obsidian plugin that analyzes Markdown notes for weak reasoning, unclear claims, unsupported statements, and incomplete action plans.
It can, but only optionally. The core checks are deterministic and local. AI enrichment is an add-on for people who want a second layer of rewriting or summarization with their own API key.
ThoughtLint is designed for research notes, specs, decision documents, meeting notes, and strategy documents inside Obsidian.
It returns a score, issue list, suggested fixes, extracted decisions, extracted action items, and an improved section that can be copied back into the note.
ThoughtLint starts with a local deterministic pass, so users get privacy by default, stable scoring, and a structured reasoning review even when they do not want to send note content anywhere.
