SMF·CODA
Can a prompt replace Coda?
Notes & knowledge management — docs + tables + apps
Exhibit tracking slip
Verdict
A personal doc editor with embedded tables and simple formula columns is a real weekend build. What doesn't come with it is Coda's actual depth: a full formula language, a marketplace of integration 'packs,' team permissions, and the doc-as-app workflow that makes it a platform rather than an editor.
Exhibit A — The prompt
Received on30.07.2026Build a personal docs-with-tables tool: documents are Markdown, edited with a live preview, where a specially-marked fenced block references a table by name and renders it live inside the document. Tables have typed columns (text, number, date, select, checkbox) backed by a real database, with inline row editing. Support formula columns — a simple expression over a row's other fields, evaluated safely server-side with no imports and no network access, recomputed whenever a value changes. Let a document declare a button that runs one action from a small, fixed whitelist (add a row with defaults, mark a row done) — documents should never be able to execute arbitrary code. Support named, saved views per table (a filter plus a sort) that can be embedded in any document. Support CSV export per table and Markdown export per document.
Do not build real-time collaboration, permissions, or a packs and integrations ecosystem — Coda's formula language and pack marketplace are the actual product; this is a single-user personal version of the same idea, not a platform.Opening prefills the prompt — press enter to run it.
Exhibit B — What you lose
- B.1 Coda's full formula language
- B.2 packs and third-party integrations
- B.3 team permissions
- B.4 real-time collaboration
- B.5 the polished doc-as-app feel
Prior art
Exhibit C — Why people still pay: editor/formula/integrations
A doc that behaves like a small app is what teammates can actually understand and maintain without a developer — people pay for that workflow, not for tables inside a document.
Questions
Can I import my existing Coda docs?
Coda exports documents and tables, and the table data maps reasonably well onto this build's schema. Formula columns don't transfer — Coda's formula language is proprietary, so each formula needs to be rewritten by hand.
Will it work on my phone?
For reading a doc, yes, as a responsive page. Editing tables and writing formulas is realistically a desktop task.
What does it cost to run?
Hosting and a database, typically a few dollars a month, with no per-seat or per-doc pricing to think about.
What's the one thing that doesn't survive the rebuild?
The pack ecosystem. Coda's packs connect a doc to dozens of other tools with a few clicks; here, any integration with an outside service is code you write yourself, one at a time.
