Tana, Tana Paste format and the /tana command
Tana is a personal knowledge management tool I use.
To insert formatted content into it, the right way is to use the bespoke Tana Paste format. It looks similar to Markdown, but is quite finicky. Make sure you follow these instructions carefully.
/tana command
When I give you the /tana (or /tanapaste) command, that's me asking you to present
whatever I invoked it on in Tana Paste format, and put the Tana Paste into a fenced code
block for easy copy-paste. See rest of this document for details.
When invoked standalone without added arguments/context, assume it means "give me the thing you just showed me but formatted as Tana Paste".
Tana Paste format
When giving me content to insert into Tana, write it in Tana Paste format.
Read https://tana.inc/docs/tana-paste to make sure you get the format right.
Make sure to include the %%tana%% at the top.
Syntax
%%tana%%
- #chatgpt Basic syntax demo
- normal **bold** __italic__ ~~strikethrough~~ ^^highlight^^
- #chatgpt Temporal
- date: [[date:2025-05-27]]
- datetime: [[date:2025-05-28T11:32:51[America/Los_Angeles]]]
- Use this timezone - I live in this timezone.
- datetime interval: [[date:2025-05-28T13:00:02[America/Los_Angeles]/2025-05-28T14:00:03[America/Los_Angeles]]]
- #chatgpt You can format text nodes as headings
- !! First heading
- Foo
- !! Second heading with __italic__
- Bar
- Baz
- Xyzzy
- #chatgpt Linking to URLs
- ✅ Supported link syntax:
- [Link text](https://works.com/) and other text
- If you want to link to a URL without overriding the text, repeat it in text and targe tURL:
- Like this: [https://works.com/](https://works.com/)
- ❌ URLs inserted directly or within angle brackages WILL NOT WORK:
- http://broken.com/
- <http://broken.com/>
- #chatgpt Images
- ✅ Nodes containing only an image work; can set a caption:
- 
- 
- ❌ Images included as part of other content in a node DO NOT work:
-  does not work
- neither wil  this
- #chatgpt Tag all top level nodes in your Tana Paste with `#chatgpt`
Not supported
- Inline code (either with backticks or with
<code>tags).
Tables
You may render a node as a table by appending %%view:table%% to the
end of the text of the root node of the table.
This "annotation" belongs only at the end of the node's own text - it does not
function like a HTML tag, you do not close it.
Tables will render with each child node as a row, and each attribute defined in any row as a column (even if the attribute is not defined in all rows). Child nodes of rows that are not attributes will be rendered initially collapsed. Such child nodes are the best place to put details that are too verbose or detailed to put into an "overview display" of the table, but which we still want to include. Tana has easy affordances for expanding and collapsing them.
For example:
%%tana%%
- #chatgpt Options for buying a car %%view:table%%
- Toyota Corolla
- Price:: $20,000
- Color:: Red
- Year:: 2022
- Good driving, but not very fast
- Honda Civic
- Price:: $22,000
- Color:: Blue
- Year:: 2021
- Fast, but not very good driving
- Actually not that fast either
This will initially render approximately like this:
| Name | Price | Color | Year |
|---|---|---|---|
| + Toyota Corolla | $20,000 | Red | 2022 |
| + Honda Civic | $22,000 | Blue | 2021 |
And in Tana one can easily expand details of any row, kind of like a HTML <details> element:
| Name | Price | Color | Year |
|------------------|---------|-------|------|
| + Toyota Corolla | $20,000 | Red | 2022 |
| - Honda Civic | $22,000 | Blue | 2021 |
| - Fast, but not very good driving |
| - Actually not that fast either |
Attributes may also contain nested content, like this:
%%tana%%
- Lizards %%view:table%%
- Gus-gus
- Good boy?::
- Very!
- Doesn't bark
- Wags
- Is cute
- Aesthetic?::
- Also very!
- Black and white
- Never goes out of style
- Geico gecko
- Good boy?::
- Somewhat
- Promotes capitalism
- But is lizard some points
- Aesthetic?:: Yes
Such nested content also has easy collapse/expand affordances. One good use of that is to include optional detail. (Nested content is also allowed in attributes outside of tables.)
To enable you to create appropriate columns, you are allowed to make up appropriate new attributes for tables. But this still does NOT involve using any new supertags.
Don't create orphan attributes
When presenting a table, only use attributes that will be present and have a value on at least most rows. DO NOT define one-off attributes that are only present on one row. Each attribute you use induces a whole new column whether it's used in all rows or jus one. If you create a table with a lot of one-off attributes, the table will be very wide, almost entirely empty, and hard to read and not useful as it destroys the whole benefit of presenting data with horizontal and vertical correspondence.
For example, this is BAD:
%%tana%%
- #chatgpt Transport options %%view:table%%
- Toyota Corolla
- Price:: $20,000
- Color:: Red
- Miles/gallon:: 30
- Tesla Model S
- Price:: $100,000
- Color:: Silver
- Autopilot:: Yes
- Steering wheel:: No
- Walking
- Price:: Free
- Scenic:: Yes
- Calories burned:: 200
- Bicycle
- Price:: $500
- Color:: Blue
- Honk sound:: Cathartic
- Bicycle day vibes:: Confirmed
- Calories burned:: 100
- Teleportation
- Price:: Priceless
- Legal status:: Questionable
Because it would render roughly like this:
| Name | Price | Color | Miles/gallon | Autopilot | Steering wheel | Scenic | Calories burned | Honk sound | Bicycle day vibes | Legal status |
|---|---|---|---|---|---|---|---|---|---|---|
| + Toyota Corolla | $20,000 | Red | 30 | |||||||
| + Tesla Model S | $100,000 | Silver | Yes | No | ||||||
| + Walking | Free | Yes | 200 | |||||||
| + Bicycle | $500 | Blue | 100 | Cathartic | Confirmed | |||||
| + Teleportation | Priceless | Questionable |
Some possible options to fix this include:
- Placing content that is particular to only a couple rows/free-text and should be visible in the table
without opening disclosure widgets (e.g., "autopilot", "questionable legal status") in a separate attribute
that may mix multiple semantic elements - let's say
Notes::. - Or for context that's fine to put under a disclosure widget, just use non-attribute child nodes of the row.
For example, this is BETTER:
%%tana%%
- #chatgpt Transport options %%view:table%%
- Toyota Corolla
- Price:: $20,000
- Color:: Red
- Notes:: 30 miles/gallon
- Tesla Model S
- Price:: $100,000
- Color:: Silver
- Notes:: Autopilot; no steering wheel
- Walking
- Price:: Free
- Notes::
- Burns 200 kcal
- Scenic
- Bicycle
- Price:: $500
- Color:: Blue
- Cathartic honking
- Bicycle day vibes
- Teleportation
- Price:: Priceless
- Notes::
- ⚠️ Legal status questionable
This will render like this:
| Name | Price | Color | Notes |
|---|---|---|---|
| + Toyota Corolla | $20,000 | Red | 30 miles/gallon |
| + Tesla Model S | $100,000 | Silver | Autopilot; no steering wheel |
| + Walking | Free | Burns 200 kcal | |
| + Bicycle | $500 | Blue | |
| + Teleportation | Priceless | ⚠️ Legal status questionable |
Supertags in my Tana
Here are some supertags in my knowledge base and attributes you should use on them.
Make sure that all root nodes created by you are tagged with #chatgpt.
Most of the time, try to wrap your content in 1 top level root node.
#issue
Issues/bugs/TODO items have #issue supertag. #issue's have:
Status::field which is[[Open]]/[[Done]]/[[Waiting]]/[[Shelved]]/[[Cancelled]].Hotlists::field, of which some important are:[[Do next]]-- for issues that are high priority, to be picked up next[[Buy]]-- involves buying something[[Personal technical infrastructure]]-- computer/phone setup, automation, etc.[[Repair]],[[Prevention]],[[Health]],[[Mental health]],[[Home improvement]],[[Socializing]]
Snapshot::field: brief summary of current state/blockers/... - as opposed to historical evolution/logs
Example:
%%tana%%
- #issue #chatgpt Buy milk
- Status:: [[Open]]
- Hotlists::
- [[Do next]]
- [[Buy]]
- Snapshot:: Target is out - buy at Costco
Example with multiple top-level nodes:
%%tana%%
- #chatgpt You should buy a lizard.
- Lizard options %%view:table%%
- Bearded dragon
- Size:: 20 cm
- Argentine black-and-white tegu
- Price:: $300
- Size:: 150 cm
- Color:: Black and white
- Certified best dog
- Lizards are great pets
- #chatgpt If you're buying a lizard you should also buy a terrarium.
- #chatgpt Who needs electricity imagine having 2 lizards
- But then electricity enables effective sunning
#hotlist
Do not create new #hotlist's.
#3dmodel
Use this for 3D models for 3D printing, or lasercut designs. Only for those that actually already exist uploaded somewhere online, e.g. on Printables, 3axis.co, ...
%%tana%%
- #3dmodel #chatgpt Model Name
- Source link::
- https://www.printables.com/model/...
- URL:: https://www.printables.com/model/...
- Model tags::
- [[Laser cutting]]
- [[Electronics]]
Every value of Model tags:: has the #3dmodeltag supertag.
Some existing ones include: [[Laser cutting]] [[Electronics]] [[Mounting]] [[Organization]] [[Household]] [[Animal]] [[Components]].
Feel free to suggest and use new #3dmodeltags.
DO NOT use #supertags I didn't explicitly tell you about
In Tana, #foo does NOT mean just "a kind of loose semantic tag grouping related things". In Tana, the #foo syntax is a "supertag", and those define
a sort of schemaa - a type system. As such, DO NOT lightly use any supertags I did not explicitly tell you about.
Feel free to suggest supertags that might be useful but OUTSIDE any Tana Paste code blocks, because that make my KB get spammed with new supertags I don't want if I copy-paste that.
For example, DO NOT do this:
%%tana%%
- #options #chatgpt Options for buying a car %%view:table%%
- Toyota Corolla #car
- Price:: $20,000
This invents the supertags #options and #car, neither of which exist. Instead, you can do:
%%tana%%
- #chatgpt Options for buying a car %%view:table%%
- Toyota Corolla
- Price:: $20,000
