OBTF vs Notion vs Obsidian: which note-taking approach fits
OBTF, Notion, and Obsidian solve the same problem — keeping notes — but they are built on very different assumptions. This guide compares them on practical criteria and explains when each approach makes sense.
In short
- OBTF — one text file, newest entries on top, search with
Ctrl+F. Minimal structure and dependencies. - Notion — a workspace of blocks, pages, and databases. Its strength is collaboration and flexible views.
- Obsidian — a local vault of Markdown files with links, tags, and plugins. A compromise between structure and data ownership.
Comparison
| Criterion | OBTF | Notion | Obsidian |
|---|---|---|---|
| Format | One .txt | Cloud blocks and databases | Markdown files in a local folder |
| Structure | Chronology and markers | Pages, properties, databases | Folders, links, tags |
| Offline | Full | Limited | Full |
| Search | Ctrl+F, grep, rg | Built-in search and filters | Full-text search and backlinks |
| Collaboration | None | Strong | No real-time collaboration |
| Images | Links to files | Embedded blocks | Embedded files |
| Extensibility | None | Templates and integrations | Plugins and themes |
| Dependency | An editor only | Notion cloud | App and plugins |
| Large volumes | Good with a text editor | Can slow down | Depends on plugins and vault size |
| Learning curve | Minimal | Medium | Medium to high |
When OBTF is the best choice
OBTF wins when speed, autonomy, and longevity matter. A single file opens instantly, works without internet, and survives changes of applications. It is easy to read, search, copy, and feed into AI tools: a RAG workflow can use the raw text directly, with no export or block parsing.
The approach suits personal notes, journals, task logs, drafts, and a knowledge base that should remain readable in 10–20 years. It does not require maintaining a hierarchy: structure emerges from dates, markers, and repeated sections.
The limits matter too. OBTF has no built-in collaboration, nested pages, backlinks, or proper image display. If a team, a client database, or complex views are required, one file quickly becomes awkward.
When Notion is the best choice
Notion shines in team scenarios: wikis, project boards, CRM, content databases, and documentation with permissions. Its block model combines text, tables, Kanban boards, calendars, and embedded databases. Templates and properties provide predictable structure without programming.
The trade-off is dependency on the cloud and a subscription. Full use requires internet and sync; offline access is limited. Export to Markdown or HTML is possible, but complex databases, relations, and views do not transfer completely. The more logic lives in Notion, the more expensive migration becomes.
Notion makes sense when the value comes from collaboration and structured data, not from the text itself. For a personal archive meant to last decades, it is overkill.
When Obsidian is the best choice
Obsidian sits in the middle: files live locally in Markdown, but links, tags, a graph, and plugins sit on top. This works well for research, knowledge bases, and notes where connections between topics matter more than chronology.
Obsidian does not lock the text into its cloud: a vault can sync through Obsidian Sync, iCloud, Dropbox, Syncthing, or Git. At the same time, the app and plugins add a layer of dependency. The more plugins and custom syntax, the harder it is to move the vault to another tool.
If structure and connections are needed but collaboration is not, Obsidian is a reasonable choice. If structure only gets in the way of writing, OBTF is simpler.
Hybrid setups
- OBTF + Notion. Keep a personal OBTF as a daily journal and inbox, and use Notion for a team wiki and project database. Move only finished documents between them, not the entire stream of notes.
- OBTF + Obsidian. Use OBTF as an incoming file and develop individual topics in Obsidian. Do not turn OBTF into a pile of Markdown syntax: it should stay readable without Obsidian.
- OBTF + AI. A text file is easy to pass to local or cloud models for search and summarization. Notion and Obsidian usually require an export or a separate connector.
Moving to OBTF
- Export your current notes: Markdown or HTML from Notion, or simply copy the Obsidian vault folder.
- Normalize the entries: date, heading, text. Do not try to preserve every property and relation.
- Assemble one file in reverse chronological order. Older entries can stay in blocks by year.
- Put images and attachments in a separate
attachments/folder and reference them as text. - Keep a backup of the original export and delete it only after the new file has been verified.
Bottom line
The choice depends on constraints, not fashion. Need collaboration and databases — Notion. Need local Markdown files and links — Obsidian. Need a fast, durable, portable personal archive — OBTF. These approaches do not have to exclude each other; the most practical setup is often a hybrid.
