It s a 100% free, minimalist writing tool that uses AI to:

1. Find the best sources

2. Fact-check

3. Spell-check

but puts the onus on you to actually write.

As someone who enjoys writing, I love using it myself and I think anyone who wants to keep their own voice, research well, or jot down ideas will benefit from it without having to rely on AI to do the thinking.

After reading that MIT study on how using AI to write can reduce memory and critical thinking, we at IdeaTBD knew we wanted to build something fast - a tool that helps you write, not write for you.

So we gave ourselves 48 hours to ship an MVP. Here's what made the cut and what didn t.

What We Shipped

• A simple, clean writing editor

• Real-time fact-check and spell-check

• A research side panel that pulls from trusted sources

• Instant text analysis to highlight potential BS

• A zero-distraction UI

• Basic autosave and history

We ve been building Idea TBD in public - a weekly drop where we share raw product ideas, highlight early-stage tools, and experiment with building a community around curiosity and creativity.

It s scrappy. It s messy. It s ours.

Here s what we ve learned so far

Substack Traction

Ever since going full entrepreneur mode, my Instagram feed is flooded with business tips, marketing frameworks and founder hacks. Some of it is incredible but let s be real:
I save these reels, never revisit them and never actually apply the insights.
What if we built a tool that pulls transcripts from your saved reels, uses AI to summarize and categorize them, and resurfaces insights when you need them?
Potential features:

• Auto-transcribe + summarize reels you save

• Tag + categorize by topics (e.g., growth, copywriting, retention)

• Send weekly digest of your saved insights

• Integrate with Notion / Slack / Asana

• Chrome extension or mobile widget: Show me saved insights related to X

Basically, turn your endless saved reels into an actionable strategy library you ll actually use.

Does something like this exist already?

The Problem
Fandom lovers crave immersion, but most fan experiences are stuck in passive mode: watching shows, reading books, or scrolling Reddit threads.

Meanwhile, social media feels like the opposite of magic: doomscrolling, recycled takes, no real spark.
The Idea
FictionFeed: a social network built inside fictional universes.

Scroll through a feed of AI-generated updates from your favorite characters: Elrond, Tyrion, Hermione - all speaking in their native tone and lore.

It s like Instagram Fan Fiction Immersive Roleplay.
How It Works

Problem

"Building in public" is broken. We re posting into the void - no structure, no momentum, no real collab. Twitter s loud, Reddit s messy, Discord s buried. Even in communities, we re still building alone.

Solution

A kanban-style social network for builders.
