One conversation at a time
A clear path from context to your words.
Thoughtline starts only when you ask. It reads the visible conversation you selected, gives you useful directions, then gets out of the way.
- 1
Choose the context
Right-click what matters.
Select one visible post, comment, or reply. Thoughtline stays inside that boundary.
- 2
Find your angle
Explore four directions.
Add insight, ask a question, extend the idea, or respectfully challenge it.
- 3
Make it yours
Edit, copy, publish.
Refine every word in the side panel. Nothing is published until you do it yourself.
More than replies
Build a writing practice, not a content machine.
Refine rough writing
Paste a draft or reshape a selected post through your confirmed perspective and voice.
Research source-backed ideas
Find promising ideas across public sources, with a link back to every original item.
Choose the hashtag finish
Set 0–10 generated hashtags and save custom tags that follow every generated or refined post.
Carry your setup forward
Export one validated configuration file and restore it during onboarding or in Settings, with secrets included only when you choose.
Keep useful work close
Search, edit, revise, and export local history without turning your work into telemetry.
Made for your voice
“Useful AI should leave you sounding more like yourself, not less.”
Your language
English, Bangla, or naturally matched to the source.
Your guidance
Tone, topics, audience, examples, and an editable style guide.
Your approval
Every draft remains editable and every publish action remains yours.
Boundaries are a feature
Private by design. Limited on purpose.
Thoughtline is intentionally not a bot. It analyzes only what you explicitly select and keeps you in control of every outcome.
