Import a CSV or Excel file, or link a Google Sheet or Airtable view that stays up to date. SpecStream fills in what each row is missing, such as the owner, an email, a phone or a website, and puts every address on the map. Combine several lists into one, and a place or company that was in two of them is kept once. Compare records, export them as a file or send them to your tools, and share selected snapshots with the visibility and expiration you choose.

Who is it for?
For everyone with a spreadsheet they wish did more.
Top features
Import any list. Free.
Map names, websites, cities, countries, and coordinates from a CSV or Excel file, a Google Sheet, or an Airtable view. Keep additional columns. Imported values stay labeled as yours.
- Fill in what’s missing. Choose the rows and the details to add, such as the owner, an email or a phone. SpecStream looks each one up by its website, a page link, or an ID such as a company number or DOI, and fills only the empty cells. The quote comes first.
- Start with the list. View, filter, map, compare, or organize it in a project before running new work.
- Keep it in sync. A linked sheet or view is checked every day for new and changed rows. Your notes and views stay put.
Hand the list to your agent
Read it, cut it down, and send it on. Your agent works from the same saved results. Paste these into any agent connected over MCP. Click one to copy it. Your agent reads it and runs it.

Is it for you?
It earns its place when:
Go with if…
- Your list should be useful before you buy anything
- You want snapshots that never change under you
- Shared links should expire and be revocable
- The next step needs CSV, Excel, JSON, or HTML
Use it with the rest of SpecStream.
Every SpecStream tool works on the same lists, so nothing gets copied from one to the next.
